One of my friends had the same problem, after the harness it was done. Let me know what happens, I might learn something new.

 

Hey, just had that same problem myself....dealer is replacing the Brake switch. Hopefully problem solved.

 

did your 3 brake lights not all come on when you tapped on the brake pedal?

 

Update:

Replaced the harness today and so far so good. But the end link that popped out and was put back in has already popped back out again. A new possible theory is that has something to do with it. The timing of the ABS/PSM warnings and this sure are coincidental. I am getting new end links installed soon. Hopefully next week. Will update what transpires...

 

When the PSM/ABS lights were on, I never checked if the brake lights didn't come on. That's a little scary....

I know they came on when I wasn't getting the error. It would usually go away if I turned off and turned back on the car after it warmed up.

I brought my car to the dealer and they had it diagnosed in half a day.

 

They took a half day to tell you it was the brake switch?

Let us know if that solves the problem.

 

I had the same issues recently, it turned out to be bad MAF due to BMC air filter. They replaced it with a new MAF and the problem was solved. My car was running just fine too with the bad MAF.

 

What error code(s) did it throw when it was scanned?

 

I had similar damage to my RF ABS wiring harness. It runs very close to the plastic battery vent hose. For whatever reason, acid from my OEM Porsche battery burned a hole through the vent hose, and proceeded to melt the ABS wiring harness. The "warranty repair" by Gaudin Porsche (Las Vegas, NV) consisted of wrapping the wiring harness with electrical tape. After that, I drove from Las Vegas to Newport Beach, CA for all my dealer service.

 

No, didn't take half a day for just the brake switch. They also diagnosed a leak cause by the clutch slave cylinder failure and had to drool over how hot my car is =)

 

After installing the new clutch, I have not seen any ABS/PSM yet. This is getting confusing now. I will keep all posted.

 

Art, that's weird. Hopefully it stays away...

I have driven 200+ miles since the new harness was installed yesterday and so far so good..

 

Getting the same thing. Rarely but I do. I usually get it after I wash the car in cold weather. I switch ignition off and on and that cures it. Subscribed to this thread...

 

That is good to hear.

 

Exact same issues as me. I should get my car back early this week....will let you know how it is =) If it doesn't snow maybe I'll even drive into work.

And of course it won't snow since I've bought a Copper 4Pass.
