Hi Folks,
As posted in an other section, i got a gti last night. Long story short, drove it home then engine management light came on.
Today I have noticed a lumped idle slightly and a slight missfire on idle. Now and again missed a beat when fut down. However, it drives great and goes. Been in 1.8t's alot and doesn't feel any different at this point.
My mate scanned it at his garage today and threw up 7 fault codes. As I said, no EML when I drove the car away from the seller until I got home. I think he reset the codes so the lights went off. I never took a note of them, but 3 codes where for cylinder 1,2,4 misfiring.
Now I am doubting that all 3 coil packs have went, like I said, it drives sweet, just on the idle you can feel the miss fire.
Now I got home tonight and scanned with my ebay vagcom and produced this. Please note the EML was not on when I scanned it with vagcom tonight.

No other address's had faults. As you can see, no misfiring faults. On the first scan by my mate, it also had a code about lean mixture. Apologies, I should have taken note of it.
Now over the past 24 hours, the things I have noticed, climate control, ac, etc...all work bang on. The car sometimes idles normal around 800, sometimes, 950 and some times 1100 along with the slight misfire. I think it needs a new thermostat as the temp never gets to 90 unless sitting idleing.
Some hissing from the front of the car bay (rear of engine I guess) which I am thinking is an air leak, It sounds like underneath the injector rail, but I cant get allen keys until tomorrow.
Also this morning the ESP light came on and stayed on. At lunch went out and started it up and the light went off?? It hasnt came back on and this was before the scanning. It turns on as normal for testing.
I put £15 of vpower in it last night and towards the end of the day today when running empty, there were some knocks from the engine when ideling, but was all good when driving. I have just went and put £20 of shell normal 95 and the knocking is gone. I scanned with vagcom after running it with the normal 95.
Please note the car is fully stock and no remap either.
I thinking the knocking was down to the fuel? And something to do with the misfire. I read a few topics last night (after putting vpower in it...and the general response was to use 95 with a stock map?
Any advice or feedback would be appreciated. I realise that the post is very long...so thanks for reading. Just going to do some googling on the fault codes.
Thanks
Liam
