Issues post head gasket

[jimmernet]

Hi

I got a 2001 stock S3 - owned it from new and in 120k not a single engine component failed (xcept coil packs - all changed 20k ago) on it until a few weeks ago when it had to go in for a head gasket change -Rude awakening there!

Anyway, since then the car aint right -Under hard acceleration, it hesitates around 5k rpm in 4th/ 5th and the amber engine light flashes for a bit until I back off. I'm getting these codes from VAG com...


Control Module Part Number: 8N0 906 018 J
Component and/or Version: 1.8L R4/5VT 0004
Software Coding: 10710
Work Shop Code: WSC 06435
Additional Info: WAUZZZ8LZ1A056408 AUZ7Z0Y1650315
4 Faults Found:
17705 - Pressure Drop between Turbo and Throttle Valve (check D.V.!) P1297 - 35-10 - - - Intermittent
16487 - MAF sensor(G70): signal too high P0103 - 35-10
16684 - Random/Multiple Cylinder Misfire Detected P0300 - 35-10
16685 - Cylinder 1 Misfire Detected P0301 - 35-10 - - - Intermittent

anyone got any ideas? After the big spend on the head job I gotta dig these out for myself...

Thanks guys....

leaky pipes, suspect maf sensor,, coil packs failing.. plug gaos too big

start with the search for leaky pipes tho. very commone and can cause mayhem in running issues

Cheers bill - I reckon the pipes gotta be the problem since they all came off for the head gasket.
