Well, turns out it was yet another dud ABS sensor. All up and running for a few weeks now.

Im still befuddled by the ABS fault. When I remove the front left sensor from its socket and let it hang lose the ABS fault doesn't come on, but the Traction faulure message does. Plug it back in and the ABS fault message returns, followed by the Traction message a few seconds after turning on...

After a couple of months this fault has re appeared. Usually about two miles into a journey, but also occasionally the fault doesn't appear at all. It can happen when driving or, strangely, when stationary. It can come with no warning, or sometimes there is a loud chattering from behind the...

To round this post off I have refitted the original ABS sensor now. No further problems. Pity the cheap ebay sensors caused a bit of confusion.

Hmm, that fix didn't last very long. the ABS Fault and Traction Failure lights popped on today as I was driving. Not accompanied by the ABS judder that was previously apparent.

Thanks to one and all for helping me out with this fault. Now armed with plenty info on blend motor replacement.

I'm very glad to report that this fault is now cured. I had installed a new ABS sensor before discovering that the reluctor ring had a crack in it. So, after replacing the CV joint we reinserted the new sensor. Turns out that it was a dud. Replaced it with another new sensor, and the fault...

This fault is running away with itself. We spotted a crack in the reluctor ring, fitted a new CV joint which comes with a new ring. Now I get an instant "ABS Fault" indication followed by "Traction Failure" after moving off and also again when I switch the engine off. I've read in another...

The reluctor ring will be checked tomorrow. I hadn't realised until today that a Wabco sensor is £150. So the £20 ebay sensor could be a waste of time?

So, a new sensor fitted with no change in the fault. I've checked the wiring from the ECU to the sensor socket, all appears as normal. I've replaced the ECU, and also the ABS relay. Still no joy. As soon as I'm over 20mph the systems starts the ABS clicking, when I drop below 20mph it has no...

Thanks everyone, it is indeed the rogue sensor that's causing the fault. I'd been scrabbling around and reading too many forum posts, some of which suggested that the ECU could be causing the problem. I had thought the relay could be at fault because it sounded like a relay chattering on and off...

Found the ECU under the glove compartment. The connectors are clean. This gave me the chance to check all the sensor resistance readings easily at the ECU plug. Three read 900 ohms, and are isolated from the chassis, the front near side reads 1200 ohms and has a resistance of 10 Megohms to the...

Hi folks, I've been running my 2001 P38 4.0 for almost five years with relatively few problems. This week though the brakes started playing up. As soon as I touch the brake pedal above about 15mph the ABS kicks in. It stays clicking away for several seconds after releasing the pedal. It can make...

Thanks Ridesafe, not sure if the mechanic did bleed the brakes properly. I gave him a printout from the RAVE CD to follow. He hadnt done one like this before so maybe a second try would sort it. I'd try myself but the last brakes I bled were in the mid 80's on a Vauxhall Chevette! I thought...

Hi, just joined up today. I've had a 2001 P38 for just over a year now. LPG converted, with petrol here at £1:38 it would be impossible to own a vehicle like this otherwise. Great car, not without its small niggles though. Cheers Kenny

Hi, new to the forum and had a good look around for previous posting regarding my brake problem. I have a 2001 P38 which recently started having a spongy brake on applying slow pedal pressure. Occasionally it will not be spongy but a hard push with a small "kickback". A pump runs every second...
