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.

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.

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.

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

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

@diydaly Жыл бұрын

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

@10casem Жыл бұрын

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 :)

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!

Always at just below 3k revs with low amounts of throttle, speeds seems to be irrelevant but usually happens low ish speeds.
