VAGCOM fault codes

[Kevgrady]

just had MAF go on my mk 3 ibiza cupra so replaced it today for a new one, on way back from parts dep in floored it in third gear and at 6000rpm it went into some kind of safe mode or limp mode but im certian it wasnt in limp mode, so when i hooked up VAG com i found these codes
1.) 17964 - charge pressure control: negative deviation
2.) p1556.

can anybody tell me what i needt to replace?

boost leak or n75 mate, you got vag-com?

 

[Kevgrady]

no but my mate has

I guess you reset your ECU after you replaced your MAF. If it was reading really low and you just replaced it then the adaption will be out by some degree.

On Topic your code describes LIMPMODE!!!!!

This is generally caused by either lower than expected boost pressure, leaking pipes or more likely a faulty N75 valve.

Hope this helps.


edit :- Too Slow......

Make sure the car is cold for best results.

Disconnect the -ve battery terminal have a brew.
Come back in 20mins Reconnect the terminal.

Turn key in the ignition to the second position for about 2mins. Turn key again to start engine go for a drive. See how it feels.
