ABS Issues - What Else

Recommended Posts

Hi,

 

As seems to be common with a lot of other corrados, I have an issue with the ABS light intermittently coming on on my VR6. Obviously with my MOT due in about 3months, I would like to get this fixed as soon as possible. The problem is fairly intermittent - 50% of the time the light will come on when I start up and then go out as normal, and the rest of the time it will stay on and occasionally even come on in the middle of a journey.

 

I have had the fault codes read using VAGcom and the codes were as follows:-

 

Address 03: ABS Brakes

 

9 Faults Found:

00285 - ABS Wheel Speed Sensor; Front Right (G45) 35-00

00290 - ABS Wheel Speed Sensor; Rear Left (G46) 35-00

00287 - ABS Wheel Speed Sensor; Rear Right (G44) 35-00

00290 - ABS Wheel Speed Sensor; Rear Left (G46) 16-00 - Signal Outside Specifications

00287 - ABS Wheel Speed Sensor; Rear Left (G44) 16-00 - Signal Outside Specifications

00283 - ABS Wheel Speed Sensor; Front Left (G47) 04-00 - Mechanical Malfunction

00290 - ABS Wheel Speed Sensor; Rear Left (G46) 04-00 - Mechanical Malfunction

00287 - ABS Wheel Speed Sensor; Rear Right (G44) 04-00 - Mechanical Malfunction

00793 - Brake Pedal Position Sensor (G100) 35-00

 

The previous owner already had the ABS light problem investigated by a VW specialist who discovered that the ABS ring was out of shape which they straightened out and thought had resolved the problem.

 

Unfortunately it doesn't seem to have worked and I am just wondering where I go now? From the fault codes that have been generated, it looks like all the sensors have thrown up errors but surely if that was the case then the light would be on all the time. The last code is for the Brake Pedal Position Sensor so I am wondering if this may be the actual cause of the problem and I should try and get it refurbished by DG Autotech?

 

Cheers,

Peter

Did you clear the codes and rescan then again after a drive?

 

If they come back I'd expect water damage on the ABS ECU with that many...

So you've cleared the codes and the same ones keep coming back? If that's the case then you'll need to check / replace the offending sensors.

 

As for the PPS, that's usually caused by a dry joint. Do a search as there's a big thread on it.
