what would you say the following faults are..

[jason-jm]

MAF AIRFLOW SENSOR SINGAL TOO LOW...

POWER SUPPLY TERMINAL 30 VOLTAGE TOO LOW

Charge pressure control positive deviation...



all sounds a bit scary top one is obviously maf.. but the other 2

 

[mrk]

Charge pressure control positive deviation...
sounds like n75

 

[Dan Cupra R]

Ive got the same fault but NEGATIVE deviation rather than positive yet, the car still seems fine

 

[jason-jm]

my car runs.... OK but not as well as it should

does the boost occasionaly cut out?

 

[jason-jm]

does the boost occasionaly cut out?

yes veery often

 

[PhilW]

Overboost. Your spiking too high coz of possibly a dodgy N75 or wastegate cranked too much.

You disconnected the battery is the other one.

 

[jason-jm]

So new n75 and a new MAF "SHOULD" solve my problem

 

[PhilW]

Change the MAF first, fix the one you know is ****ed first.

 

[jason-jm]

Im ordering it this weekend providing the other two company's refund me my £170+ for the other 2 ****ed maf's


n75 cost much?

 

[pj1985]

N75 are about £40 from vagparts. Im sure TTS Roadsport will be able to do you a good price aswell as Alex is a good bloke. Or you couls look second hand if you were tight for money.

 

[Spud_G40]

I've changed both my MAF and my N75, still have positive deviation, limp mode all the time on spool up. My actuator rod is in standard position. Never get to the bottom of it.

 

[PhilW]

Wind the actuator out more then.

 

[Spud_G40]

Taken it back to 7 threads, still does it. Is it possible the actuator on the turbo is damaged causing this? Or is there such a thing as a faulty N112?

 

[jason-jm]

Wind the actuator out more then.

and one of those is a what?

Id do that how? sorry new to all this

 

[Spud_G40]

Its ok he was talking to me, did'nt mean to hijack, just I have the same fault.
