96 VR6 MAF and Cam Position Sensor? VAGCOM

[ob1 0]

Hello, i'm new to the forum so i'll post a hello later... but can anyone help ihave just got a new car and have now got vagcom up and running with these errors

00668 Battery Power Voltage Supply (Terminal 30) Signal to low.

00515 P0340 Camshaft Position Sensor (Hall Effect Sensor) - No Signal (G40) : Check CMP, if OK, replace distributor

00561 Mixture Adjustment Control

00553 Mass Air Flow Sensor -G70 Short to B+ intermittent

00522 Engine Coolant Temperature Sensor -G62

I have cleared the faults and so far they've all stayed gone except the cam sensor. is it worth trying to clean this part or should i just replace it?

also i have been reading how you can use a 2l MAF instead of a vr6 one in mk4's and save a packet ? is there any way you can do simular on mk3 vr's?

any help would be appreciated. cheers orlando

thanks helpful link!

in actual fact the fault code is;

VAG-COM Version: Release 409.1-S

Control Module Part Number: 021 906 256

Component and/or Version: MOTRONIC M3.8.1 HS V02

Software Coding: 00000

Work Shop Code: WSC 01315

1 Fault Found:

00515 - Camshaft Position (Hall) Sensor (G40)

29-00 - Short to Ground

So i presume this is the sensor itself ? do need to realign the throttle body after changing? can i do that with unregistered vagcom? thanks again o

short to ground could mean the plug is not seating or break in the wire

sensor is not expensive

Camshaft sensor was gone on mine when I got it, replaced it with a second hand one from a breakers I know and it's been fine ever since. Makes the car drive odd though, no low down grunt.

The MAF you can get from GSF on a part ex, about £80 for an OE Bosch one.

thanks, the maf code has come back, is it worth cleaning this as its an intermitant fault or should i just replace? cheers o

update: have changed the cam sensor and wow thats better completely different car! much improved fuel economy too... thanks all....
