i just recently got an 05 1.8t manual quattro and it has the tick and rough idle. the tick does go away once the engine has warmed up but the rough idle stays. been suggested to look at the engine mounts
Rough idle will most likely be a pcv breather valve or the pancake valve at top located at the back of the engine, although minor leak in the intake turbo piping may also cause this. The tick you describe it's located at the back of the engine, most likely will be the timing chain tensioner which need to be replaced along with the half moon gasket seal
Hey All, getting an 04 A41.8T soon so will be coming to the community and Stuie for all my advise, glad I found you guys and thanks for the Video Stuie, really prepared me for the road ahead with my new (old) car.
The tensioner by default when broken in will be slightly loose at when the engine is off since its oil pressure driven along with an internal helper spring.
The ticking is fairly normal, it's the timing chain slightly knocking against the head cover gasket, rough idle I experienced for years and then only by chance replaced the breather and pancake valves, the car has been sweet ever since and has been like that for the last 5 years.. Annoying when trying to fault diagnose though, try squeezing breather valves and when you come to one that smooths out the idle, your culprit will be in that area..
@stuiesgarage sorry, I meant squeeze all breather hoses, mine subdued towards the back of the engine very low down, replaced all the hoses with no luck, threw loads of money at it.. I gave up and a few years later, summat at the back needed replacing, got the valves as had read about these,, but forums throw you off track, so ignored. Long story short, they cost £7 and £11 each genuine from tps, couldn't believe it finally worked! But also check your using e5 petrol and not e10, 1 tank I tried and it misfired horrendously! Which I'm stumped about.. But never made the same mistake and it's been sweet ever since
Camshaftbelt jumped 4 notches, right after the bolt in the crankshaft broke.... i am so saaaad. But the engine run 301000km...so i think it have done its job.
Hi Stuie. My 2004 ticks also and I suspect the timing is off marginally after a belt replacement but not sure. Anyways you make great videos, thanks for them.
Personally, I do also believe the car is not ideal in the very hot weather's you experience in America.. Plastic and rubber components do not bode well in extreme hot weather, mines in the UK and tbh, after initial teething issues, it's lasted 15 + years and still sounding sweet along with decent power, Common faults are coolant flange, pcv valve, the older ignition coils, boost leaks, plastic water pump and chain tensioner which disintegrates and clogs up the oil pickup tube located in the oil sump as well as the dreaded wiring loom in between the car door due to opening and closing over time. The manual Transmission very reliable, wish I could say the same about the automatics tho lols
I own the 1.8 Manuel versions have had timing chain busted and nothing else luckily failed except the bypass valve due to me turning up the e boost. Mechanic fried ecu doing engine work had to replace ecu at 100k miles. Having major coolant leak all of it gone after several miles used to barely leak now it’s exploding out. Was curious if the coolant flange was the result to that problem
Звук может быть из за изношенной постели распредвала или самого распредвала. Это случается из за краткосрочных перегревов головки блока, которая очень чувствительна к этому, так же из за неправильного подобранного слишком густого масла. В корпусе масляного фильтра стоит маленький шариковый обратный клапан, который не всегда работает исправно и стравливает давление из головки блока при простое. Густое масло усугубляет положение.
No, it was after doing a full engine rebuild, I did swap out the timing chain and hydraulic lifters to see if that would make a difference but it didn’t.
@stuiesgarage please could you assist, my A4 B6 leaking from the radiator and I suppose there may be a blockage in the coolant system and that’s the weak point or the water pump may have given in and that the blockage any advise would be appreciated. Too scared to drive it now.
Hey buddy that knocking is most likely from a piston, sorry to bring bad news. Someone said chain slack but it should be noticeable at idle and go away once you rev up, yours is the opposite, bet you at higher rpm’s it get louder… right..?
When chain slack turns to rattle at start up before smoothing out after oil fills up, it's tensioners that are worn. Easiest way to prolong the inevitable, just leave key in ignition position for a minute or 2 before firing up to give tensioners chance to fill up with oil, then start
Just watched your last video a few minutes ago. Just got an 02 a4 1.8t (not quattro) and been trying to figure my gremlins out. Check engine light and red oil light, esp pops on and off. Have no horn (guessing fuse, I can hear it click in the wheel), door jam issue for window (driver), and a short of power in 1st-2nd. At 90k, just had oil done and coolant res replaced. Any advice
Red oil light is the serious one -it means lower than spec oil pressure, which might mean your oil pickup tube is partially blocked within the sump. ESP on/off in my experience would be your G85 steering angle sensor, located behind the steering wheel, part of the clock spring. They dry out over time. Car kills the traction control (illuminating the ESP) because it can't read the angle of the steering.
If you hear a clunking sound from your wheel which is intermittent along with esp intermittent, check the driveshaft axle is properly tightened in the offending wheel, mine did what I described and as I was taking a steep bend, the driveshaft popped out! Car refused to move and could here it turning on acceleration but like a knocking /grinding sound. Thankfully garage diagnosed and confirmed drive shafts axle popped out the wheel bearing hub, literally popped back in and tightened, been sweet ever since
I haven’t been able to solve it, I replace the timing chain and all of the hydraulic lifters but it’s still there. Timing is good and idle is smooth, not sure what it could be, but I haven’t had any engine issues or metal in the oil, so I guess it’s ok. I’ve put 40k miles on this engine with the tick.
interesting, ive got the same tick but mostly on cold oil. extremely loud when its cold. im sure its lifters but getting worried when i hear stories like yours. but then again i would be happy if it lasted me 40k. thanks for the quick reply @@stuiesgarage
@@stuiesgarage I don't think so I think it's a combination of an air leak that it had before going to the mechanic and I now think the cat is gone the car feels stuffed
Is it the O2 sensor (downstream), or the air fuel sensor (up stream)? You will definitely know because a failing/failed air fuel sensor will inject way too much fuel into the cylinders causing tons of smoke and a distinct raw fuel smell. If its the downstream sensor, that would also trip a code. In my instance, I thought a new sensor would do the trick, but when I removed the downpipe with the cat, which you have to do, I looked at the filters in the cat and they were about 90% clogged. A lack of power, and bad fuel economy is a good indicator. I bought a new magnaflow cat and installed it. The power came back along with better fuel economy, but it still tripped a code after about two weeks. I used that cat because it was a shade under 6 bills. Apparently, you'll need a Audi cat which is 2 grand. I live in a county in Wisconsin where emissions isn't required, so I said "the hell with that" and installed a test pipe with a O2 sensor extender which is welded at 45 degress, so it fit with room to spare. I have been driving for 8 months with this set up and no check engine light. If your going to do this work, be warned that your downpipe may need to be replaced also, along with the clamp that secures the downpipe to the cat, and all the gaskets and grade 8 or better hardware.

Check your spark plugs. They can break in weird ways and cause the inner part of the plug to move with compression.
I just did them pretty recently

Poor choice .. Kid.
Nah, depends on how well it's been kept.. Solid engine in manual, just make sure you use e5, ie v power, they're very sensitive to the e10 crap
@@barenekid9695 sad to hear that but unfortunatley it wasn't much of a choice and it's too late now, but it seems well kept.
got one 3 months ago dont regret it atm, idk if urs is awd quattro as well but mine is a beast so far

Hi Stuie. My 2004 ticks also and I suspect the timing is off marginally after a belt replacement but not sure. Anyways you make great videos, thanks for them.
I’m looking at picking up an 04 B6. How often would you say you’re actually having to wrench on yours? Looking for a fun daily.

Is this noise after replacing the timing chain and tensioner?
No, it was after doing a full engine rebuild, I did swap out the timing chain and hydraulic lifters to see if that would make a difference but it didn’t.
@@stuiesgarage you replaced the oil pump with a good tensioner and the timing chain, the original cost is 500 euros
@stuiesgarage please could you assist, my A4 B6 leaking from the radiator and I suppose there may be a blockage in the coolant system and that’s the weak point or the water pump may have given in and that the blockage any advise would be appreciated. Too scared to drive it now.
The front timing cover comes off pretty easily, you should be able to see the water pump from there if you’re trying to track down a leak.
did u ever figure out what was causing that ticking? currently having the same noise coming from my 20th gti
Yeah it still ticks, been doing that for almost 40k miles now and seems fine, haven’t changed at all
Oil pump/pickup tube
The ticking can come from a bad exhause gasket. It is a paper-metal gasket and if the paper goes away the metal can make i ticking sound

I had the phantom coolant leak..from the "j" plug

yes

Any other codes?

Possible, seems a bit too loud for that
Chain slap
It's Junk ! Get a new better brand car.
Personal opinion, new cars are made using cheap materials these days, they fail like crazy!
fyi if u wanna get ur tire off the easy way loosen the lugs just a lil and drop the car on the ground quick it will break the tire loose from sticking
Thanks, that sounds like a much easier/safer way!
