Quick way to check without even moving the engine cover is by quickly removing the glow plug relay in the fuse box under the bonnet. All four pins can be checked from the relay socket. Also proves the cables to the glow plugs are good too.

I’ve just done this and all 4 glow plugs read 0.7-0.9. They all seem good but still getting PO684 fault along with all glow plug code faults. Assuming this is relay at fault is there any tests I can do to prove it’s 100% the relay?
Thanks, I had the same code, same cylinder, it cleared itself after a good bit of time, after I was all set to pull and replace the glow plug. the fault never affected the starting noticeably. Same engine, same year. Now I have an intermittent pressure sensor issue, your info was super helpful. I just reseated the connectors as it runs okay. Nice work.
Helps to run engine for a few minutes before trying to undo if glow plugs are tight. The aluminium head expands faster than the steel glow plug so sometimes this makes them undo easier.
Yeah I run engine till coolant fans come and got some heat proof gloves on and strip as fast as can or leave engine running and start stripping and undo plug whislt running to see if free havent snapped a glow plug yet but seen alit of lads at my work have as done it from cold engine
I will be putting high heat grease on the threads when I get into them next. I warped one glow plug when taking it out because the socket was not a perfect fit. Very silly to design it with paper thin metal housing.

Great video thanks. looking for advice please. Ive a 2009 Q5 1968cc Starter motor has to turn engine about 10 times when cold. Scanned and got the 4 codes P067100 + 2 + 3 + 4. Ok I know it's showing the 4 heater plugs issue. However could they be ok and it's the module and not the plugs? Would a faulty module show it's own separate fault? Or is the module giving false error as in faulty plugs which are not faulty? Looking forward to your reply Thanks MOR
Hi great video would the plugs all be the same even tho you have a no 3 different? I got poor starting and glow plug light on dash is very fast to go out. Thanks
I have thesame engine as yours and do have starting issue's, i removed glow plug caps and they all look the same, there isnt the one with the sensor. Does the car need to have the one with sensor? Notnsure what old owner did and replaced with normal one
My engine hesitates as I hit higher revs I.e gathering speed to go on the motorway.. would replacing these be a good idea (they do the same jobs as spark plugs?) 😂 sorry just had a bad experience with a garage so looking at ways to avoid. Thank you for the videos!
@coinzyuk2472 my car also does this without any faults logged so far then today I get a fault with glow plug on cylinder 3 which has this pressure sensor. Not got the new part fitted yet. Have you solved yours yet? What car is it pls?
@@tombowman4489 haven’t got it sorted yet mate, just got a hefty £800 bill from the garage to get it through its mot 🙃 won’t be looking at getting it sorted till the start of next month boss
@@diydaly no not any fault codes logged at all even though the problem has got more frequent. Always at just below 3k revs with low amounts of throttle, speeds seems to be irrelevant but usually happens low ish speeds. Only thing I've had logged as a fault is this very expensive glow plug but this has been going on way longer. Would an injector issue not log a fault? thanks for your reply man.
Unless I need to go back to learning how to use a multimeter no reading at all open loop would be bad right I have the one with the sensor one probe down where the sensor goes and then one on the body like you said got no no reading open loop
Hi great video Iv had same issue on Vw caddy van 2018 code p13d6 the pressure glow plug has been replaced however after a couple of days driving the engine light comes on and produces the same code. Any ideas thanks

@@diydaly yeah i’m gonna replace all 4 anyway especially at 140k now i do 20k a year lol so is that meaning it just needs replacing then (open circuit)
Hi amazing video definately subscribing! Quick question, I have a MK7 GTD and recently had all 4 glow plugs changed but didn’t put the glow plug with the pressure sensor in and now there is a check engine light and also says cylinder 3 compression fault on the reader. Will putting the pressure sensor glow plug in the correct place (cylinder 3) fix the issue? And would you recommend an Amazon purchase for the glow plug? And where would I find the correct glow plug size and spec? Thank you
ive listed a link for the glow plugs in the description.. did yours have a pressure sensing plug originally then? you should be able to fit the wrong plugs that all as the connectors are different from pressure sensing / normal glow plugs
Thanks for the reply. Yes organially there was a pressure sensor on cylinder 3 and no there’s not which is why I am confident this is the reason for the check engine light. On my cars and the other golfs they have cylinder 3 pressure sensor so I’ve ordered the part going to hope it solves the issue :)
@@diydaly Hi its me again. The glow plug has been fitted but still shows the fault code of P03AE. If its not the glow plug pressure sensor could it be the wire connector which sits on top of it? if so what is the best way to check it? Thank you
@@10casem yeah possibly but very unlikely , I’ve won’t had and faults with the connectors but you’ll need to make sure it’s got a 12v feed when required ..
comment on an old vid. I've got a similar car, but with the push button start. Is there a way to get the glow plugs to activate without cranking the engine? Normally, you'd turn key to ON first, is it similar? ie push button but not foot on brake. TIA
did the car run crap with this cylinder 3 sensor issue as my kodiaq is jolting on drive and hard to start at times and idles bad at times and this fault is all i see on odb diagnostics. no lights on dash though
Hi mate, just wanted to know the engine variant ? As I’ve got a 2016 scirocco 2.0tdi 150bhp . It’s the updated version with the black engine cover rather than the black and white one… could you help and inform me with this one please mate ?
My 1.9TDI Seat Leon is having issues to start every now and then. Took it to the local garage and the guy there told me that glow plugs are irrelevant for Portugal climate since its never too cold. Also thecar is park in garage. Injectors showing healthy values.. I mean... i trust this mechanic but could he be wrong?
I have mk6 jetta tdi that just recently showed glow plug and engine compression fault. I replaced all the plugs with new. However, the new all looked alike. They all have the "castle" looking top. The glow plug fault is now gone, but I am still getting a cylinder pressure fault. It runs flawlessly, quick, fast, with no stutter to the engine. Just the pesky compression code. Any ideas? Did I use the wring glow plugs on 2-4? I'm feeling lost!
If I cleared the fault without it being replaced, will it appear again. As I have been told it can appear as the temperature outside goes colder. My car is a seat Leon mk3 1.6 TDI. Thanks

They might activate very shortly that way, its hard to say with modern stuff, ive never checked that with a push button start
So mine says cylinder 4 glow plug .. so does it go left to right looking at it forward …. 1-2-3-4 or is it 4-3-2-1
1 is always the timing belt side not gearbox
my 2013 insignia has4 sensor plugs, do 4 sensors have to go back on or can i have 1 sensor and the cheap ones ? thanks
I’m afraid they have to be replaced with the same style.. the connectors won’t fit otherwise
Did you use any kind of grease on the new plugs?
Neh I didn’t , these aren’t known for seizing in
Well explained thank you
You're welcome
Great stuff - thanks for the effort!

I have replaced all the plugs but after 2-3 cycles of the car, the light pops up again. Would you know what that could be?
have you read the fault codes?
I have same problem. Do I need to put 1 Pressure sensing glow plugs and 3 normal glow plugs or I can have all 4 normal?
No I’m afraid the connectors are different so you need to replace each one like for like
