Problem with ABS & PSM problem with new wheels

[Mike D]

Hi,

I just put a set of Carrera III wheels on my 2002 Cab. with the Same tires. I put 7mm spacers on the front yesterday with my original wheels and noticed I got a ABS and PSM failure when driving today. I put the new wheels on and got the same error today. Any ideas?

Thanks

Mike

wheel witdth is 8 x 18

offset is 57mm w 7mm H&R spacers. The problem occured after putting the spacers on with the original wheels

Thanks

Try without the spacers.

Porsche only approves up to 5 mm spacers on the front.

Same without the spacers, as soon as I hit the brakes, I get the errors.

So, both lights come on when you apply the brakes?

Yes, PSM then ABS. it does not matter if the car is moving or not

Check to see if your brake lights work.

If they do then you could also have a bad MAF.

BINGO, if I press the brakes just a little the break lights come on, if I press downfurther as to stop, the lights go off

I moved the switch in and out a couple times, seems it was stuck and could not come oput all the way, it is fine now

amazing the two things were unrelated

Thank you!

Adjust or replace the brake light switch on the pedal.
