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

delete them all and see what comes back!

Sorry I did the vagcom scan with the car off :laugh:. Away to do it with the car running this now.

check with vw if the coil-packs have been replaced under the recall they had :smiley:

Like take it to VW?
Just scanned the car with it running. Same 4 fault codes as above. Im am thinking Vpower had some part in this. Going to try unplugging the maf this now.
Have just taken a video of it running. Will try and get onto utube shortly.
Thanks

Spot on. Took the plug out, started it and its purring like it should be, other small engine vibration, but not as bad when plugged in.
Turned the car off, connect the maf again, started up and reverted back to what it has been doing.
New maf I guess. It doesnt help when it shouts service now too. Its being serviced on Saturday.
Thanks

yay. .... . :smiley: :laugh: i love it when problems are resolved :grin:

So Im thinking -
MAF
16891 - Idle Control System RPM Higher than Expected.
P0507 - 35-10 - - - Intermittent
16486 - Mass Air Flow Sensor (G70): Signal too Low
P0102 - 35-10 - - - Intermittent
ECU - This is normal?? From other topics on the net, it just means there is fault codes stored on the system?
01314 - Engine Control Module
013 - Check DTC Memory - Intermittent
This could be a bad one. Theres a guide on the net for testing the flap via vagcom. Going to do it soon, but have seen photos of entire dash boards ripped out to replace it? The climacontrol things is working perfectly and blowing strong :huh:
01274 - Air Flow Flap Positioning Motor (V71)

The flap is just the one that governs the recirculating or fresh air part of the system

Cool. Some Audi forums say it's a problem they live with. Do you know if it really needs to be replaced at some point?
Done the havoc test and everything sounds good. Blows hot too.

Found the air leak. The T piece for the brake booster which goes into the inlet manifold (underneath, neext to dipstick) has as major slit in it. Soon as I put my finger up to it, it sucked it in lol and the engine went back to normal.
Just going to phone VW shortly to get a replacement. I was planning on doing the N249? & PCV delete, but require to do some heavy reading on it. I take it, there no quick way of just removing the vaccum in the interm for the brake booster?
Thanks

Top right hand of engine bay. Its on the pipe that runs into the air box. You can't miss it lol.
Be gentle with the connector when unplugging it. May be best to use a flat head screwdriver if the plug is really stuck on to the MAF>
