PSM / ABS warning light

[996TT-MAC]

996TT PSM and ABS waning lights came on PSM was switched off , cleared after a restart, anyone any idea's.

Is this likely to be covered by warranty?

Any help much appreciated

MAF failure? Might be covered, really depends on your relationship with your dealer. Around £400 (includes fitting) from an OPC.

Thanks its booked in for an oil pressure switch, only introduced yself to te dealer last week when it wnet down, will try them when im in this week.

Can you tell me what MAF standards for please feeling a bit silly.

Thanks again MAC

Mass Air Flow sensor. It's used by the car to gauge the airflow entering the engine.

Also can be ABS sensor- had this with the wiring going on the front causing the the ABS/PSM lights to come on. And no Porsche did not pay despite having a repair kit in stock!

Listen, don't worry about it! There is a stack of issues/connections that make the PSM/ABS light flash up.

Do not replace MAF, you will know when a MAF pops, it usually blows under heavy acceleration and you will feel it (the light will stay on regardless)

If you are really concerned get a code reader or pop down to your dealer.

Could be the brake lamp switch? replaced one recently as was causing PSM faults, dealers normally carry them in stock

Cool Mac! Just make sure before you commit to any work that may need undertaken, make sure you come on here and clear it with the boys first, they will keep you right without getting ripped off!

Whats going on, this morning I opened the car to get something from the glove compartment from the passenger side, then went round and opened the driver door and heard a vibrating noise coming from behind the dash sounded like behind the radio but I didnt even have the key in the ignition any idea's or am i worring too much.....

I had a similar scenario (the PSM and ABS lights not the noise behind the dash)

Originally it was thought to be a MAF problem, this was changed and the fault was still there.

Two possible options - problems with the ABS sensor (estimated to be ££££s) or as it transpired another switch somewhere in the breaking system (less than £7 for the part.

Good luck !

MAF is def covered by dealer it's in the warranty book too if they question it. I had mine changed.

Same happened on mine, along with the car showing higher boost pressures up to 1.1 bar, it was the MAF!

Cheers guys going into workshop tomorrow morning to get sorted, cheers for info on warranty will help the wallet.....

[Thorny]

My lights lit up like a christmas tree inc ABS, PSM, and brake distribution ones when i was stuck in the mud at Goodwood FOS. Stopped on the way home, locked and unlocked the doors and all ok...

Well guys found it its a cracked y pipe at the turbo 38 for parts being fitted monday, thanks for the help, I was wondering why it wasnt scaring me anymore, its loosing boost lol.

Cheers again, learning fast but going from 150bhp to 420bhp i guess I got a little more learning to do....
