HELP HELP - ECU issues i think

[Edd]

Can anyone give me advise on my messed up MK3 Ibiza Cupra 2000.

A couple of weeks ago my traction control light came on and wouldn’t turn off.

I got a local garage to plug my car into the machine and it came out with a list of erros. See below:

Tankvent value P1425
Boost p/control value P1547
O2 sensor B or 3 (I’m not sure), sensor 2 P1117
Sec Air sys pump relay Circ P1435
Sec air inject value circ P1421
Turbo by pass value P1289
Mass Air flow circ low input P0102

The garage said it could to the ECU need replacing. I have no idea because I'm not good with cars.

Has anyone got any idea's.

Thanks,
Edd

water might have got in the ecu , it happened to mine , just get the hairdryer on it , it is under the scuttle panel by the front wipers , worst possible place that seat could put it IMO , you might be alright if u get the hairdryer on it now , if any water hasnt soaked into the ecu that is

does ur car still run ok??

Nick - I'll try that. Anything is worth a go.

ttothec - It runs ok, but feels like the turbo isn't kicking in.

i would try just unplugging the MAF and seeing if it drives any better

the errors that were logged on ur ECU may have been from other problems and never cleared

the problem might just be the MAF

what i would do:

get all error codes cleared using vagcom, then go for a drive, then scan again and see what errors come up

btw, if u unplug the MAF and it drives normally that points to the MAF failure
