I am new to diesel engines, I have seen a lot of related videos but this one was the best for me, informative, educational simple and short. Thanks for sharing it and keep up the good work.
thankyou for this vid, my mk 5 vw golf s sdi is struggling to start every day i have to pump the gas ALOT to get it started. till a mechanic told me its no doubt my glow plugs. so straight on ebay, i bought 4 bran new ones and will fit them myself because i have watched you do it on your video saving me getting robbed if i went to a garrage and as you know we have to save money where possible these days. thanks again.
Worth adding..the glow plug relay can be at fault, it's generally located under the fuse-board in the engine bay. Access by removing the fuse-board, or much more easily by taking out the battery, and retrieving it sideways from underneath the fuse-board.
I had a ceramic glowplug come out without a tip, what a pain that turned out to be. Head had to come off, chipped piston and a valve, so I can only assume it happened when running. Fortunately it was only superficial damage and engine continued to run fine after reassembly (and still does).
They dont recomend it because it can lead to overtightening the plug pushing it more inside the chamber. As long as you ise common technical sense it should be fine
15 nm ( newton metres ) for UK views. I used torque wrench to also undo them, also set to 15 nm. I sprayed plus gas on the threads when re-installing. I then used torque wrench to tighten, but found it "snug" below 15 nm ( newton metres ) so did not go tighter. Mine were the originals ( 11 volt version ) on 17 year old VW tdi with 126,000 miles. I dont think they will need changing again. I used genuine VW "Bosch" glow plugs and not a different brand so I know the replacement were made identically & should last as long as the factory original. I also replaced the harness too as it was cracked in a number of places and again used genuine VW so I know it should last another 17 years at least.
Tell me more about the harness replacement, please. Did you have to splice it in as he suggests in this video, or how far back along does it go until there's a connector? Are the genuine harnesses expensive? Thanks.
@@PaulGuiry @Paul Guiry I just simply cut the original wire back as far as I could reach without having to remove anything. I then just measured the distance after fitting the new harness and cut the wire to match the piece cut out. I then got a chockablock and connected the wires and wrapped in electrical tape
Well done and very informative video. Excellent points with the 5 and 7V plug voltage and anti-seize. If that same glow cylinder's plug fails again and has erosion like that, you probably have a bad injector. Glow plugs are cheap, injectors are not. Hoping you just had a bad glow plug.
i got a 2008 passat diesel can you please tell me if the glow plug location is in the same places,,thnks the reason for asking is so i dont have to guess where is it located i just bought the car i dont really know much about vw cars
What happens if you don't torque it? Even on my old car the mechanic simply got an impact and tightened the spark plugs down to seat. Can't we do it until tight with these too?
Hi, I have a Skoda rapid diesel 1.4 and I've managed to replace 2 of the glow plugs nut the ,iddl;e one seems to be different like a lot thicker and a different connector, do you know what this could be and also once the problem is fixed does the warning lights automatically go off or do i need turn them off? thank you.
I'm going to be replacing my harness, maybe today. You mention weather proofing the harness. What do you mean? And is using some dielectric grease on the electrical connector a good idea? (To keep moisture and sure out of the connection.) And if you put some anti-seize on the threads doesn't that affect the torque used ... aka you need to slightly reduce the torque to avoid over torquing it? :-)
@@RollYourRock (MK4 TDI ) It's been a while but I think I just replaced all four plugs. Pretty sure I still had an issue and narrowed it down to the harness. The biggest problem that I had with the install was installing the new harness. They ones available need to be spliced into the existing wiring. There isn't a lot of existing wire to work with so you won't have a lot of chances to get it right. I soldered and shrink wrapped my splice...wasn't as pretty as I would have liked....but it's been working 100% since then. I also put some dielectric grease on the connections for the glowplus where they connect to the harness. We can get over 30C in summer, and below -30C here in winter....and so far, no issues. :) I also didn't use any anti-seize on the treads. Just torqued to whatever the recommended value is. As I recall I'm pretty sure that I also put some dielectric grease on the bare wires in the splice before I shrink wrapped them. Just some extra peace of mind to keep corrosion away.
great help this video. I had code P161C which is faulty plug cylinder 3. Guided by video I checked resistance, all 0.5 ohms except cyl 3 which was six ohms. Swapped cyl 3 and 1 plugs and got error code P161A (cylinder 1 plug). Result! Thanks My glow plugs didnt have voltage stamp on them though
I had 3 of the damned things snap off on a BMW X5 3.0D. Wasted 2 days trying to get the remaining ones out. Tried heat, cold, left hand drills and taps, e-z outs you name it. Still starts and runs ok though. Always warm the engine first and spray some penetrating fluid down there.. On the manufacturers website they'll give a value for shear torque. Set your torque wrench a bit below this and try to unscrew them. If they don't unscrew at that torque setting they'll probably snap
@n325aej yeah norbar make one. I'm sure there are other makes too. They're just like an ordinary reversible ratchet. Just look for reversible torque wrenches. Handy thing to have. And edit, it seems not all of them torque in reverse even though they're reversible.
Hello, I have a 2009 2.0 Jetta TDI with 272,000 km's so I was wondering if you recommend using diesel fuel system cleaners like STP Diesel fuel system cleaner and STP DPF Concentrated cleaner? Please let me know. Thank You.
This has to be a common sense judgement call on a case by case basis. Here, we have pretty much a like-new sparkly clean engine bay. Cleaning the plug hole threads here, would carry a bigger risk of _introducing_ debree (from the tools and means used to clean), than if not cleaning them.
Brandon Maciel if you just bought the car then you should replace them all anyway so you won't get a failure anytime soon, but when you do get a failure with only 1 glow plug then replace the only one if you had a failure when you only replaced them not to long ago, but if you get a failure after a long time of not replacing them then just replace them all because then the rest of them could fail shortly after.
My polo6 TDI 2014 model have this sign of glow plug andit doesnt exceed or comes close to 100 speed and its stressing me .Today i took it to Pinetown they said its a fuel pump needs to be changed
No. diesels do not have a spark plug, only petrol engines. A diesel works on the basis that the fuel/air mixture explodes when compressed. The glow plugs heat the mixture up at the initial fireup, to get the engine moving. With damaged glow plugs, the starting may be a problem, not the general running (although you may not get it going) Some vehicles will start from cold without the plugs, eg older landrovers. The plugs do not take a part in the ongoing engine firing like a spark plug, just at the start......
I changed all four and still get glow plug signs. It doesn't even come up on the computer but the light still flashes on the dash board almost all the time. what else could be the problem?
Have you added any LED bulbs to your vehicle? if so are they CANBUS bulbs? If not they can cause all kinds of faults on ylur dash. if not CANBUS bulbs replace with CANBUS and see if that helps.
Could be many things. Do you have a good diagnostic scanner? If not it probably won't give you the codes. I worked on a mk5 Golf 2.0 tdi gt and the coil light kept flashing because of a intermittent fault with the brake light switch.
They should come out real easy ?!?! Yea they come out so well they make kits to remove the broken ones and there are loads of videos explaining how to get broken ones out ! 🤔🤔🤔 mmm

Great demo. Do glow plugs sometimes smoke before failing my tourag won’t start glow plugs blinking. Maybe bad battery
Another good video Chitty the forum has gone to crap since you sold it, your link doesn't work now
Anyone else think he has an excellent US KITT voice 👍
Great video
Great video! Many don’t tell you to use a bit of anti seize on the threads.
Makes a big difference when you need to remove a plug in the future.

Nice informative video.....doesn't look much more difficult than a set of spark plugs. Thank-you.

Thank you for the very informative video. I've learnt something new today. Thanks again.

Great channel--I'm sorry you're no longer active.
From your other videos it looks like you're on a Jetta of some sort. What year is it?
What is the name you noticed in 4:40 ? The thing for lubricating
Hello
I have a warning glow plug light flashing on my dash. On my 1.6tdi
Is it my glow plug or injector possibly??
one caveat... if you use anti seize, you should reduce the torque from 11ft/lbs a little bit down.
To what?
@@zakbrinkhoff324 maybe 9/10ft/lbs at least a little less.
How long or how many miles do these glow plugs usually last
This video was a lifesaver for me. Thank you

Looking from the front of a 2010 VW Jett TDI, what is the cylinder order? Thank you.
So there's no need to replace the plugs unless you get a code thrown up?
Thanks for showing how to test and al that good stuff and saving me alot of time
Any advice where to buy glow plugs here in the states for a 2011 2.0l TDI ? Also, I heard you can snap them.
great help this video. I had code P161C which is faulty plug cylinder 3. Guided by video I checked resistance, all 0.5 ohms except cyl 3 which was six ohms. Swapped cyl 3 and 1 plugs and got error code P161A (cylinder 1 plug). Result!

My glow plugs didnt have voltage stamp on them though
Hi mate
Why are you using ceramic glow plugs? I think you must put the normal plug, that is not ceramic.
I am waiting your opinion...
Regards!
another easy way to test is grab a test light and clip it to B+, touch the end of the glow plug, if the test lamp lights the glow plug is good.
Thanks for the info can it give you a little bit more power to replace them all once and a while ,maybe it's a stupid question
Thanks very much, this helped me save a bunch of money and time, all the best from carl.
My OBD2 scanner says "Open Loop Glow Plug cylinder 2". I assume it means the glow plug on that cylinder is bad.
Thanks for the straightforward video!!

how to diagnose the pump-injector on TDI engine
Have you ever changed a sprinter glow plug? I about to give it a go!
How the glow plug replacement go? I'm considering changing my 2008 sprinter van glow plug myself. Was it complicated?
Warm engine slightly b4 pal
Very good and clear content 🤘
Thanks you great video 🎉
thanks for video sorted out my caddy :)
Should it be done with the engine worm or cold ?
Helped out so much. Thank you.
This was a perfect video
What size socket do u need to remove the glow plug?
10mm
would you recommend changing them all or just the one that fails?
new TDI owner, i don't have this problem yet, just curious.

i got my car from carvana
sites pretty legit
i felt like my car was brand spankin new and not 3 years old
i'm thinking they've taken care of all that
Brandon Maciel for the price of the 4 your better off changing all'.
I use cupper grease before mounting.
Great video....thanks!
I guarantee all your other glow plugs aren’t far behind...should have just done them all
Guarantee huh? Lol

Ok, então é o bimassa que tenho de trocar ao meu carro... tá assim à 2 anos, só ficou cada vez pior
is this a PD engine?
yes. look at the void and fuel pump at the right of the block.
Not all PD engines have the glowplugs located outside of the engine, the 125KW engines (BMN etc) have it located inside the engine...
My polo6 TDI 2014 model have this sign of glow plug andit doesnt exceed or comes close to 100 speed and its stressing me .Today i took it to Pinetown they said its a fuel pump needs to be changed

i did 1,9 vactra i lose them not come out after that i tight all i lose 1 by 1 i crank engine euzy pull out :)
