New MAF still get a fault

Post by Rick_RS4 » Wed Jul 31, 2019 9:15 pm

I think I hit limp mode when accelerating then the car with the tyre Mark's came on.

I bought a new MAF and it seemed to clear it , but I drove it the other day and it was on again.

VCDS says flow is at 30 g/s at idle the old one read 0.0 g/s

Been scanning etc and it gave the code p0101 but recently the car and lines and the eml are on and have the codes

P0102 and p0113

I have the revolution filter and it doesnt get driven as much as it should could it have become damp in the garage?

Would this point to maf as dont want to buy another of it's something else

Cheers

Did you:
Clean the connector with the proper stuff
Inspect the wiring for damage
Make sure it's securely inserted 'click''
Try putting an oem filter in
Is the a/m filter oiled
???

I haven't actually cleaned the plug connector yet

I've inspected the wiring but only as far as it goes behind the throttle body and joins the larger harness, my friend says hes replaced a few VW transporter maf wires so could be that.

Yeah it clicked in.

I have ordered a new cone filter, I dont have my OEM anymore.

It might have been oiled at the start but I've cleaned it many times up to now.

I need to do a voltage test on the harness

It was the Maf in the end. Took it to audi who were useless, said it was too modified, so then just bought a maf and works fine
