Broken MAF Maybe?

[Funkyfin2000]

Hi Peeps,

I have been doing some searching and its hard to get a definite answer so don't flame me for not searching

Coming up a hill near my house today, and went to floor it, there was a slight jolt/bang and the traction control light came on......then a few mins later the engine management light came on.

Hooked it up to VAG.com and came up with the following errors:

Address 01 -------------------------------------------------------
Controller: 6K0 906 032 AA
Component: 1.8L 20VT EU3 0002
Coding: 10500
Shop #: WSC 00000
1 Fault Found:
16486 - Mass Air Flow Sensor (G70): Signal too Low
P0102 - 35-00 - -
Readiness: 0000 0000

Address 03 -------------------------------------------------------
Controller: 1J0 907 379 AF
Component: ASR 20 IE CAN 0001
Coding: 13404
Shop #: WSC 00000
1 Fault Found:
01314 - Engine Control Module
79-00 - Please Check Fault Codes

I believe the engine issue is the same problem as the MAF one.

I took a look at the engine to find any blown of tubes or anything and couldn't find any. And checked for split hoses and couldn't hear anything.

I have let the car run and then pulled the MAF wires out and the car runs as normal at idle, if i try and plug it back in whilst running it nearly stalls.

The car runs as normal still though or as it did before...with the MAF connected (not tried it not connected) and boosts fine or as it did before. It isn't in any kind of limp mode.

I have cleared the codes and once revving the faults just came back again.

I have a 007 Forge DV and a Piper X induction kit on it (fitted about 2 months ago)

Any helpers would be appreciated.

Ive read it could be a fuse? if so which one??

Could i get any readings out of VAG.com to find out if it was definetly the MAP knacered...

Cheers

Rich

take the car a run and log the airflow, if the maf is buggered itll read very low or nothing at all.

 

[Funkyfin2000]

Eh up dude,

How do i log the airflow????

I have version 311-2 of VAg.com

 

[cordobabrendy]

log group two it should have air mass labelled.

 

[Funkyfin2000]

ive done it under log group 003 and got the following data:

Are you saying i should be logging it under measuring block 002?

the mass airflow at g/s is at 0.08 most of the time!

 

[cordobabrendy]

tis fooked mate, time for a new one. I doubt even cleaning it would make any difference, as its so low.

 

[Funkyfin2000]

good stuff, just for confirmation is it measuring block 002 i use or 003?

 

[Funkyfin2000]

doh, anyone know the right part number for one? suppose i could prob get it off the dealer with my chassis number
