Psm light came on also Abs fail,has this happened to anyone?

 

Happened to me just this evening coming out of a downtown parking garage. I shut the car off, then turned it back on and it went away. I hear this is common.

 

Its probably the brake sensor. I was getting the same warning lights as described. Ordered a new brake sensor from Pelican Parts.

Its a bit of pain to install (laying on your back with your head under the dash). When removing the old one disconnect and then turn the sensor a quartet turn and it pops out.

There's a good write up on 6speedonline with pictures. Just do a Google search and it'll show up.

Mine was caused by a bad MAF sensor which was fouled by the K&N intake system.

 

I installed some led tails one off the connection was faulty repaired now everything good thanks for reply

 

Wheel sensor, easy to fit but can be a pain to get old one out!

 

Have to go with him on this one, was a Porsche tech for 7years did a lot of brake switches/sensor. If you are really feeling adventuressyou can pop open the switch itself and clean the contact point with a smallfine file. Thats what goes bad they get a little burnt.
