I'm sure everyone here already mentioned; no. The water pump is not a supercharger off job. Leave it on, remove the two coolant pipes that go vertically and the belts. One doesn't necessarily say the other is failing. 44k miles and the water pump went, thermostat is fine and is staying in. PCV and thermostat? Yes. Good video all around.
just asking is okay a audi q7 tfsi 2014 please ay want to buy ???
I'm looking to buy a b8.5 S4 in the future and your videos are the most informative videos I can find on them, really helpful stuff. Thanks!
Excellent review from a well educated owner and not a mechanic. Great to watch as this is very likely the motor that I will seek in my next Audi. I do know a fair amount about them already, but your advice sure gives more insight. Thanks!
Excellent content! Just made a check list to go over as I am going to view a 2013 Q7 premium. Thanks again! Have my list ready if I buy the car I will be following the maintenance you mentioned!
Thanks. I actually watched this to precaution against what else I have to replace on my a7. Well.. I've experienced all the problems you mentioned and replaced the whole lot. That's good news.
How much did it cost you too replace everything ?
@@4eno468 alot :)
Owner of a S4 B8 Avant with manual gearbox and 125.000km on the clock. Since I live in Germany, everything is expensive as hell to get fixed. At 115.000km I had to do the timing chain and also replaced the clutch on that occasion (6800€ bill), replaced the front wheel bearings, and now I guess I have to get the clutch pedal master cylinder replaced. On the maintenance side, I replaced all driving belts, water pump, gearbox oil, spark plugs, and brake pads and disks. 10 years later the design still looks good...
Does your motor consume any oil or have to top up?
@@ozaudi9953 cca. 0.8L/10.000km oil consumption
A heap of shite
I’ve had my 2017 A7 for a few months and my service adviser just told me today it needs a new water pump and motor mounts. This vid is spot on !
Oh wow!!!
How many miles you have on it?
@@adenbaksh4843 67k at the time. Now at 69k and running good as new (after getting the work done and raising hell at Audi). Great car, just pricey maintenance without warranty
People here might think I'm an audi hater. I assure you I'm not. I had an audi a6 that I loved but one thing that car was not was reliable. People always talk about reliability as if it connected to taste. Until you learn to be impartial with brands. You won't really now what reliability is. That was my case. I've owned Mazda, Audi, Toyota, Honda, mitsubishi etc. And I know it's all anecdotal. But I've save so much money since I switched to Toyota it's insane. Most Toyota cars are not fun. It's quite a bummer. But damn they are reliable. My audi was comfy, luxurious, fun and started conversations with others all the time. I get that. But I was suffering financially because of it. Both of my Toyota cars now have almost 200 thousand miles and all I do is fluid changes, tires and filters. And I live in a state where we get rough winters. And not a spot with rust. I'm not against fun cars or anything. I've dreamed about buying a gtr since I was like 10 years old but I'm so glad that I finally know what true reliability really is. And the money I've saved OMG. I guess this time and age. You have to choose between reliability and fun. Just saying. I hope this comment helps others out there.
so this engine is good? or no 2014
These cars are for singles with a good pay stable job, or mechanically incline people. Parts are expensive and if you use cheap parts you create other issues in the car.
True before I have gti all the time problems now I have my camry 3.5 it's saw saw saw reliable and its saw powerful for people think its slow it's true I smach many good car in the road and I keep my money in my pocket if you need sam think you motivated you go to you tube and put camry v6 vs mustang 5.0 and you understand and thank you for your honesty I like my car more 😊
Nothing beats Toyota reliability, there is no other car brand I would say that can match up to Toyota reliability, Honda is probably the closest it gets to Toyota reliability
My Toyota aristo, hiace (2rz) and 89 Toyota pickup all have done nothing but be reliable to me. ❤
Great video man! Looking at all these issues in the next week since I have a 3,000 mile warranty to take advantage of!
Good luck with claiming on warranty work!
How did you get on ?
Good explanation of maintenance and problems may occure with Audi 3.0 TFSI engine 👍
Thank you for the information, I'm looking at getting a a7 3.0 and wanted to know what to look for.
hey man thank you for this info. Ive got a 2013 B8.5 S4 Avant here in New Zealand 8 years in ive done pcv t stat and water pump. The only major stuff i love my S4 such a great car.
Very informative thanks mate!
Great video. I have 95 K on a 2017 I think I 'll take mine in to change all those out.
Great video. But I thought you said you'd mention a few things about the DSG transmission. Heard and read a lot of issue about it (DL501). The stories make me more scared of the transmission than the engine.
Thanks for the insight brother, doing some research before I buy my mom's 2015 a6 s-line. Only 52k on the odometer but it has developed a nasty oil leak, just gonna give her a good once over and hit the problem areas you mentioned.
Engine mounts just done on my A7. The coolant system is being done in a couple of weeks.
Thanks for this video, it helps alot
Thanks, this is a great help!
Hey just wanna say great video just subscribed to your channel I’ll be watching your videos. Looking to get a Audi s7 or a7 pretty mechanically inclined just don’t know what platform is going to be the most reliable.
Good vid. Temp, Thermostat, and coolant tank at 80k miles. Then suspension components - Bushings will likely go if you live in cities with rough roads, as well as your shocks - at 70k, you'll feel it. At 90k you'll definitely feel it. With this, your lower, upper control arms at front, then various other suspension components depending on where you live (I live in a city with terrible roads with speed bumps in the highway).
Overall, this car is very low maintenance. The Iridium plugs should last up to 60k miles, but it can go well - never had a misfire on my car. Oil will start burning off - likely need head gasket replaced.
Plan this out and you can save some money on the work you need done.
I’m looking at one that runs great but found multiple misfires pending. Not sure if this can just be spark plugs and air filter/ tune up items. Is it probable this will resolve? Most importantly what are the most common culprits
I'm looking to buy an A6 C6 3.0Tfsi, good content, thanks. Probably i'll replace waterpump and pcv at begining maybe chain and belts too. Is there any known issue about oil consumption like 2.0tfsi's ? Is Pistons reliable ? I had 4 Total engine rebuilds last 5 years, 2 of them A4 b8 and my Honda fk2. Audi had bad rebuilds and Honda had bad software which knocks at boost. I dont want again a engine rebuild adventure.
You are the man. So smart.
great video bro 👌
Great info, thank you.
Do you have a video of a typical timing chain rattle?
Subbed. Great video, thank you
I wanna get one ina a year or two I started working at Audi so I already saw some of this coming but I feel pretty confident I can keep it running
You're the man! 👍👍👍
Informative video - thanks. You didn’t mention any issues with catalytic converter‘s for these engines. I’ve done a little bit of research and seen quite a bit of discussion on the subject. I’ve been noticing a rattle when decelerating just before the engine shifts into the next lower gear (on a b8.5 S4 with 126 km or 78k miles on it). I thought it might be a rusty exhaust bracket or something of the like, but couldn’t find anything like that. I was thinking it might be the cats that are starting to fall apart inside, and that’s when I noticed all the pinned discussion points on catalytic converters. What is your experience in this area?
From what I understand the cats are located right next to the exhaust manifolds. They're a pain to get to. Chances are if you are only experiencing a rattle on acceleration, it could be the flex pipe next the exhaust that has worned out or ripped. I recommend checking that area first before pulling the cats out. If you aren't on a tune then you should be okay. Also check the PCV valve as well. If that fails, oil might get into the exhaust too and could wear it out too.
It’s the flex pipe, mines done it for a few months now and I thought it was cats, but the flex pipe is prone to tearing. Look up some videos of it it’ll probably be exactly what’s wrong
Hi, did you solve it? I have a similar sound while decelerating from about 30km
@@danieltene2048 yes, it was the flex pipes. Sadly, there are no aftermarket options, unless you go to much simplified system (ie louder). So, I think that the parts alone were CDN$1800.
whoever is only driving 5k miles a year i salute you. my odometer gets 10k plus within a few months
Have a 2009 3.0T. Belt blew out on me 2 weeks ago and ended up changing pretty much the entire assembly (tensioner, harmonic balancer which had the rubber lining practically falling apart throughout, idler pulley). Went ahead and did the same w the supercharger belt. Got just about 115k as well so heads up to anyone coming up on that was quite the hassle
how much did it cost to fix?
Hello. I loved your video and the car.
I am close to buying 2017 sportback S5 TFSI but it has 98,000 miles (158K km) on it. Would you say it is reliable enough to buy it even now ? I know its important who had it before but i dont know, its a random used car dealership. Thank you
Good stuff, thanks!
Is the work to clean the secondary air injection ports covered by Audi if you get a CEL for codes P0491 and P0492 together at the same time?
nice videos . is like describe my car issues exactly in order. . . .. already changed PCV, coolant pump , engine mounts , and also tensioners .. . . i don't know if common or not but i have a little Shock when changing gears 1.2..3 at low rpm and Audi suggest that is clutch . now i think this is not common especially that car has 135.000 km . anyway thanks for video if any other issues glad to find out. my car is an Audi A6 Allroad 2016 TFSi .
and if you are apr tuned stage 2, use the bkr9eix spark plugs
Are there any issues wit the newer turbocharged 3.0 TFSI that comes in the new A6 Allroads?
Is there any chance you can do a similiar video on the BBK V8 engine in b6/7 S4?
While accelerating around 40-60km/hr, I getting rattling noise from right side of engine on my Audi A7 .. what could be the problem??
Any problems with the stock crankcase pulley?
I am looking at A7 55 tfsi as their value dropped quite a lot. Is it worth buying or will I be working overtime just for repairs? Any info on this specifical car?
How about the chains? Are they considered as a common problem?
Question I changed the separator and I put it all back together and now fuel is dumping. You have any idea where this could come from?
Hello I’m looking into buying one tonight. How was pricing on maintenance. Is it fair? Expensive?
Usually software issue. Pretty sturdy trans.DSG
Great video and very good points made about this engine. I have just a question if you know better, just got a 2013 Audi Q7, it has a misfire on cylinder 6, I ve got New spark plug, New coils but still not firing the spark plug no.6, it’s injecting gas but no fire. Do you have a small idea what can be ? The EPS and Traction Control is on, I think also because of that.
man ay want to buy this car q7 2014 tfsi is good??? some people have tell me just old q7 have been this problem
check compression, probably worn cylinder
Potentially ignition control module
Was it worn cylinder?
What is the mileage that the water pump failure may occur?
How do you replace coolant in a 2016 q5 3.0 v6 ?
Hello there nice explanation on everything. I just replaced the pcv/ crankcase valve on my 2017 audi Q7 3.0t. After putting everything back together I got a check engine light and a p2014 code. Any idea if I forgot to connect anything. Thanks.
I actually am considering Q7. But right now I decided to consider BMW
Why is the quality of Q7 so bad?
Did you ever find out what the code was.. I'm about to get my pcv changed
@@tonylaw5010any of you guys have any conclusions?
Hello, great video, i am looking for an S5, I know that many of these car have oil consumption problems, very high consumption. I read is because the thermosta had caused overheating and in many cases the Audi did changed the pistons. So do you think if I put a refurbished engine with new pistons this will happena again even if the thermostat is ok? Do you think is a bad engineering of the engine block itself ?
im looking for an s5 myuself too
Late response but yes the thermostat overheats constantly due to bad positioning and poor quality, many have used aftermarket thermostat and thermostat housings and have seen a decrease in oil consumption but still had signs of some pretty heavy consumption, most Audis do this besides a few older models. The transmission tends to leak too and ECS Tuning has an almost oem replacement kit for like $200-$300 with better gaskets and bolts. Many of the fails with Audi products are that they are owned by VW so they use cheap wiring, gaskets, and a lot of plastics where metal would’ve definitely been needed. So expect some gasket changes and if you keep using oem thermostat it’ll just keep burning up. You could fabricate it and move it farther from the block. But the readings will be slightly off
This is like when I feel sick and google my symptoms instead of asking a real doctor.
When you say engine filter are you referring to the air intake filter??
Think I'm correct in saying you omitted to mention it's an engine out job to replace chains and tensioners ?!!
I have an A5 3.0 tfsi v6 with 320.000 km...they only thing j pay is benzin and oil for service this car is a beast
Excellent video!
How can I know if I have the B8 or B8.5? my car is an audi a7 2013
Thanks!
What shape taillights do you have ?
I have a 2010 model s4 b8, had random missfires, so I decided to change the pcv as a few forums said that could be the issue, it was a big mission, ended up changing a few broken pipes, original pcv was and thermostat where fine, but it was in bits so I replaced them anyway £350, my random missfires turned out to be blocked cats.
Could you tell me at roughly what mileage were the cats when they started to cause your misfiring issue please?
Great info! Looking at s like 3.0 and has multiple misfires pending although can’t tell driving. Any other symptoms or codes? And was it the final fix?
I own a 2013 s5 v6 ..I’m losing coolant every 3-4 weeks is going near to minimum, also seems it burns one quart of oil every 1000 miles…i have a tiny leak on the thick silicone pipe that comes out of the radiator on the right side…any ideas what should i do..? Cant find any oil leak or coolant leak under car, didnt take the shield off yet
I have a 2012 Audi A6 Quattro. I’m getting a p0089 code leading to fuel pressure sensors. My question is how difficult is the it to remove the Supercharger? The low pressure is under it!
whats ur millage? change the fuel filter
I have A7 2012. To remove the supercharger you should ask for profesionals. Theres plenty of plugs,hoses,places where you can plug in different locations, and so on. I was changing pcv unit, it is under supercharger, so you basicaly ripping off whole engine
don’t do it if you don’t have the knowledge
I've got a 3.0 q5 and I need to replace the rear hatch. Any advice or should I make the insurance claim and let audi do it for 6k? I can find the hatches all day long for 500 ide just have to paint it.. .. .
Did you mention about the oil filter housing failing and leaking because these cars have oil leak issues?
Yea I had same issues with oil leak it’s fixed now but now I’m always looking underneath see if it’s still leaking 🤬
My S5 began having a coolant leak not long after purchase hard to diagnose. Finally found it was a cracked water pump that was only leaking when cold as the heat expanding the metal would seal the hole and release when cold 🙃
how much did it cost to have fixed?
@@SkinnySkinch for me was warranty excess of 110£ warranty covered the other I think 300 odd. This is at a garage with 80£ an hour labour costs in the UK
wat you think is good engine? or no. ay want to buy a audi q7 2014 3.0 tfsi ?
Would’ve been probably 2k at least lol
I have an issue with audi s4 b8 on the manifold flap, repairing?, getting catalytic error

I’m sorry but There is no such thing as Reliable when it comes to Audi or BMW
Any tips how to maintain a used Audi q7 2013
I have a 2012 A7 3.0TFSI,, the high pressure fuel pump has started to go bad. Can i fix/service it? Or does this only get replaced?
Replace it
Are 16 Sq5 at 40000km has timing chain tension going bad and had that rattle on start up. Very disappointed with suck low mileage. The longer you left it without driving the longer the rattle lasted in start up.
A6 2015 2L supercharged consumed oil (class action suit) and then catastrophic failure of the engine. So common it’s very hard to get one to replace it with. I was dedicated to maintenance. The engines are defective.
I loved my Audi. I’d never get one again!
Hey i got My eye on an Audi a5 3.0 tfsi 7 speed automatic with 198000KM you guys got Any tips for me to watch out for?
The engine code is CMU
I’ve got that rattle on startup on my A8, an estimate for timing chain replacement? Also, at highway speeds, my air suspension purges the system and runs flat until I quickly pull over and shut the car off and restart it twice. That works every time to restart the suspension system then it runs like a dream again. Thoughts anyone? I think it’s a relay issue with the suspension.
Ride hight sensor maybe, and I would definitely get that rattle looked at by a shop
@@matthewthedude146 yaknow what, I had went to my local Audi shop, they replaced the front left and right level sensors, and she’s running like a dream again. The rattle might be a timing chain, or even just a loose gasket. Not sure yet. Thanks!
I have an A8 with the 3.0t 99,600 miles , i have timing chain rattle also, but don’t worry Audi even told me if it goes away after start up no worries
@ryan
@@TaylorDoesItAll if the rattle goes away within 1 to 3 seconds after start up its within acceptable range. If the rattle lasts longer than 3 seconds it can be a problem particularly with the upper tensioners
My Audi A7 will sometimes not exceed 1500 rpm. Anyone have any idea what it may be
Does the b8.5 S4 have forged internals?

In the same boat. Should i steer away?
Same here should I steer away?
An Audi A6 with 158,000 miles from a single owner, do you recommend it?
Very informative video. beside the subject, it sounds like this engine or car needs way more care than the other brands. I have been interested b8 S4 but it seems like it is not a good choice. I am scared to own one now as it could be Auchi S4, not Audi S4.
I wouldn't say 'way more care'. They are more reliable than most smaller VW/Audi motors such as the 2.0t. Definitely more reliable than a BMW n54, and I would say notably better than an N55 too. I dont think there are any other comparable mid-tier euro performance cars out there which are more reliable than a B8.5 S4. Yes Lexus/Infiniti will be but then you are compromising on practicality, dynamics, and most would say looks.
Don’t think like that or you’ll never buy a car full stop! I can tell you now, I have a beautiful S5 coupe, 2012 with 116k on the clock, I came from a Peugeot 308 GTI, which is literally a nightmare to maintain as everything comes from France. The Audi is typically more expensive to maintain but also typically more reliable and a lot more premium than most cars.
Is it normal for the a8 to slow it self down so much when you let go of the gas pedal while going slow? It does not coast at low speeds.
No, my S6 did that too randomly for a 1 or 2 days untill it fixed itself again. Idk what it was but it felt weird as I'm used to it coast quite good without slowing down much. So no, not normal
A coincidence we just picked up our 2013 A7 around 115k. Time for some maintenance! Can you please maybe DIY tutorial for the Idle Control Valve? I think I’m having an issue with my rpms being wonky during idle and when stopped my car died and started back up randomly in the parking lot.
Let me know what else you need to do if anything. Looking at buying one today
can someone tell me how have tfsi 3.0 q7. 2014. is good car please pecas just old audi have been with this problem?
Please Help!!! I have a 2013 Audi A7 I hit a opossum last night going about 65 MPH busted my front bumper and it ripped the 3 pin connector out of my coolant pump. I purchased a new 3 pin connector each pin is numbered 1 2 3 but the wires are solid black. I have 3 wires dangling from the harness that goes to the pump the colors are solid RED, solid VIOLET, and RED with a WHITE stripe. Does anyone know what color goes to each specific pin number????? Any help would be greatly appreciated.
I’ve owned the S4 for a couple yesrs now problem free as I speak but would like to say I much prefer the super charged engine to turbo as there’s no lag and with a stage 1 tune the thing really pulls with low down torque it’s a great all rounder, prior to owning the s4 I had a golf R which was fast but hated the turbo lag, if your thinking of buying one go for it and don’t be worried about buying one with a tune on it already the engine can hold the extra power no problem but you might want to upgrade the brakes
Hey
My AC fan is on all the time when car is on

Hi I bought a S5 2017 recently and noticed that theres a ticking sound coming from the engine. I cant work out what it is and the local garages dont really know about high performance cars and dont want to deal with it either. Any one have the similar issue or have any idea whats going on ? any help would be appreciated
Probably the timing chain tensioner. Make sure your up to date with your oil and that the belt is good. If it continues you might want to get the tensioner checked
Hi
Mine has a problem nobody seems to be able to fix. Engine revs to 5k then loses power and if I keep revving I get misfires and eventually engine goes into limp mode and EPC and engine lights come on and engine vibrates erratically until I switch off and back on. Any idea what's happening? Much appreciated!
Start with checking fuel injectors and spark plugs
@Inimbrium check the crank pulley IMO. Had faced a similar issue. The OE pulley is a two piece unit- outer part is a rubber insulation thingy, and the core contains the pulley. This 2 piece design is prone to failure with age, use and abuse. Mine failed, the belts got misaligned and started rubbing against each other.. tearing up in the process.
Fuel pump or air intake sensor failing ...
Fuel injectors or spark plugs would be my guess. Could also be shit fuel
Thank you all for replies. I will check all of those!

I just change my pcv, water pump, thermostat, and did a carbon cleaning. I highly recommend when you are doing all those things to change a $4 gasket (ELRING 236060) that connects the oil filter canister to the engine. Mine was leaking a lot of oil and it's a LOT easier to get to with the supercharger off. IMO if you take the supercharger off you should replace this gasket.
Where did you order all of these and how much did it cost you? My gf has this car and the alternator went out. It's leaking some oil and the water pump and thermostat hasn't been an issue but I wanted to get ahead of it and replace it.
approx cost of timing chain replacement job??
