But then Mike from sports and classic in manchester sorted it in 5 mins he just changed the abs sensor (so obviously wasn't done before) and adjusted the brake pedal switch!

It was the brake pedal switch on andys 996 that was not correctly set up if i remember correctly but we did fit the pressure sensor in the pump as we had one just to make sure as he lived so far away...

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi I have recently experienced the ABS & PSM lights comming on to tell me they are not working, anyone seen this fault before?? How much to rectify ?? Cheers Paul

POST 2Original post

What's the voltmeter reading? Similar symptoms to the alternator failing. £0 if you have waranty.

POST 3Original post

If you turn off the engine and restart and it does not reappear its probably the MAF sensor. Could be on its way out or just playing its occasional japes. Ive had it very occasionally since fitting a K&N cone filter and had no bother.

POST 4Original post

Probably a worn/damaged/clogged ABS wheel sensor/wire a simple OBD download should pin point it.

POST 5Original post

Ditto the MAF. If it does it on hard acceleration, that's most likely the problem.

POST 6 / ORIGINAL POSTEROriginal post

Seems to do it all the time now...... Hi All Thanks for the quick response, will take it to my local indy, I start the car, and then after maybe two minutes the ABS and then att he same time the PSM lights come on with a beep.... used to go off again if i stopped and started the engine, but that doesnt cure it any more either.. thanks, Paul

POST 7Original post

Hi I had exactly the same problem and after taking to an indy about 6 times and them losing my warranty because of their incompetence. they changed maf, abs sensor (supposedly) etc etc etc...... they said it deffo was the abs module/pump which would cost me around £2000!!!!!!!!!!! But then Mike from sports and classic in manchester sorted it in 5 mins he just changed the abs sensor (so obviously wasn't done before) and adjusted the brake pedal switch! Never had the problem since!

POST 8Original post

...as I said a quick OBD download should do the trick....my money is on a sensor too :thumb:

POST 9Original post

Hello It was the brake pedal switch on andys 996 that was not correctly set up if i remember correctly but we did fit the pressure sensor in the pump as we had one just to make sure as he lived so far away... all cases are different and will need properley diagnosing or it will cost you big £££ Mike

POST 10Original post

as mike said i've changed a few brake pedal switches for the said fault too and cured them. instead of the abs block the opc wanted to change...

POST 11 / ORIGINAL POSTEROriginal post

Thanks again guys........... Thanks I will take it to my local indy and get them to sort it I will also print this little lot off to show them... Paul

POST 12Original post

This happened to me yesterday! Accelerating hard(ish) and the two lights came on. Managed to get it home, although it repeadtely stalled at junctions and didn't want to go into gear. AA came out and plugged in their diagnostic and it came up with 'torque converter circuit open'. Had it towed to my indy for examination today! I'll keep you posted on the outcome.

POST 13 / ORIGINAL POSTEROriginal post

Good Luck Thanks guys.... she's going in to Autotech 9 (S Wales) and on their diagnostic computer at 09.30 tomorrow (Saturday) Will let you know what happens..... Mine has behaved very well... no other symptoms apart from the lights comming on.... its been very wet and slippery the last few days but she still grips like a goodun, however i havnt taken any undue chances due to the lack of ABS & PSM and conditions.... Thanks Paul :thumb:

POST 14Original post

Hello any news on the diagnostic ? Mike To the other person with the car that the AA plugged into..you need an air-mass sensor as it should read torque transfer disturbed from DME... This is a classic break down of the information from air-mass to DME. Mike

POST 15 / ORIGINAL POSTEROriginal post

had diagnostic done Ok, been up to my local indy, plugged and played and it seems the sensor 4460 requires changing, apparently this is the ABS sensor... anyone had that done on here?? and if so some idea of cost would be good :mrgreen: Thanks again all Paul
