Ive recently had my car diag tested and these were the results. The car should be running at 210BHP, but its running ***** at mo, hence getting the test done. Can anyone tell me were to start and whether one error could be having a knock on effect to create the others??I was guna start with Mass air flow sensor?Is there any of these errors that will actually not affect engine performance??Anyways, these are the error codes....

01247 - Activated Charcoal Filter (EVAP) System Solenoid Valve 1 (N80) 29-00 - Short to Ground

01262 - Solenoid Valve for Boost Pressure Control (N75) 29-00 - Short to Ground

16486 - Mass Air Flow Sensor (G70): Signal too Low P0102 - 35-00 - -

16519 - Oxygen (Lambda) Sensor B1 S1; Heating Circuit: Malfunction p0135 - 35-00 - -

Any help will be appreciated. I know its pretty much in black and white, but im sure of how to cure the short to ground faults????

 

The EVAP code wont cause a problem, but the others will.

 

Any idea where to start?I noticed Euro car parts sell the MAF Sensor for £75. These other short to ground errors etc go over my head! I dont know where either the Lambda sensor or Boost pressure valve are!!

 

I bought a remanufactured MAF from

www.ecstuning.com

for $85.

Check to see if a local Audi dealer sells them.
