Picked up my Gti today and broke down on the way home

(1/3) > >>

TornadoV:
Hi all,

Well it's not been a good start to Gti ownership so far! I bought the car as I wanted a good base to start with and as it has a full service history including a recent DSG service by a VW main dealer I thought it ideal  :signLOL:

On my way home it started missing very slightly with the engine light flashing for around 10 seconds, a minute or so later this stopped and it drove fine the rest of the journey home. I then took it out for a drive shortly after and it started missing heavily with engine light now permanently on. It now sounds like an Impreza but with half the performance.

I have done much reading on this great forum prior to singing up so I think from what I've read it is a coilpack issue, the worry I have is when it was last serviced in July VW carried out the coilpack recall. Can they really pack up after such a short time?

Many thanks,
Sam

coilpack, plug, injector, wiring or something much worse

Read the codes (make a note) and clear them to find out which cylinder, swap the coilpacks round and take for a gentle drive, check codes to see if misfire stays on the same cylinder or follows the coilpack. Do this again with sparkplugs until you determine, whether it is a plu & coil issue or whether you need to start looking at a new injector - which is a lot more costly in terms of parts & labour

TornadoV:
Thanks for that will get on the case today and report back.

I have just been checking through the history and the plugs were changed this year to Denso VK22, are these a good choice?

Do what Dan said

Although If it was injector it would be alot worse lol

heavy misfire, need fuel out the exhaust, dash looking like xmas tree and probably wouldn't start after you turn it off as there would everywhere it should be lol

If you bought the car from a garage,then take it back
