have you had it plugged into a code reader to see what error codes are stored in there ?
Hadn't at the time, although the entire reason for me going was for the mechanic to plug it in instead of taking it out and letting me know "it goes like a rocket" haha
went somewhere else today and this guy actually used vag com
4 Faults found:
17994 - Engine Mount Solenoid Valves (N144/N145)
P1586 - 35-10 - Short to Plus - Intermittent
Mechanic didn't know what this was... pretty sure I do the engine vibrates a fair bit so one of the mounts is gone, could do with replacing but far as I know shakey engine's won't cause problems... or will it... hmm
17965 - Charge Pressure Control
P1557 - 35-10 - Positive Deviation - Intermittent
Mechanic said this is to do with the wastegate on my turbo, apparently I need a new turbo which for most people would be a horror story but to me means a good excuse for a bigger turbo haha, in all honesty though couldn't tell if it's genuinely ruined or the guy just saw dollar signs when I walked in. Surely the turbo isn't the issue... hmm
17978 - Engine Start Blocked by Immobilizer
P1570 - 35-10 - - Intermittent
Mechanic didn't seem to know what this was and I told him it must be because the alarm doesn't sound... but looking again I'm fairly sure that code was to do with me putting my foot on the throttle and it cutting out, argh what the hell is causing this
16485 - Mass Air Flow Sensor (G70)
P0101 - 35-00 - Implausible Signal
No clue on this one, mechanic said something about turbo again
Readiness: 0 0 X X X
So yeah he says I need a new turbo, clutch and DMF, that's all good and I probably do but surely that has nothing to do with the problem, argh no idea with this
Cheers, pretty sure I need to read up more on egr's, always thought they just took air back to the engine and have no clue how they cause problems
