the failure always happens at high rpms, beyond 6500RPM , ABS and PSM lights comes on and then the following fault codes cshows up on the Durametric:

1) p1128 fault code 360-oxygen sensing adaptation idle range bank 1 exceeds limit value.
2) p1130 fault code 361-oxygen sensing adaptation idle range bank 2 exceeds limit value.
3) p0103 fault code 115-hot film MAF sensor.

 

Did anyone with a faulty brake switch get a specific ecu error code or just the usual faulty maf code ?

 

someone told me that it could also happen due to a weak fuel pump, i have placed an order for a 996 turbo fuel pump which i will try and see if it solves the problem.

 

Are you sure there is no boost/vacuum leak? Does the car have an errtic idle? Doe it seem to "hunt" at idle?

1) p1128 fault code 360-oxygen sensing adaptation idle range bank 1 exceeds limit value.
2) p1130 fault code 361-oxygen sensing adaptation idle range bank 2 exceeds limit value.

The car is compensating for something here and running out of adaptation range. This really looks like a leak to me.

 

Hey Ari, i checked for boost leaks recently but none found, the only idling issues am having is when starting the car for like the first 5 seconds the rpm seems to be hesitant and jumpy, but after that it idles normally between 800 to 900 rpms.

 

Right. Took my car back to my tuner, Fearnsport. Told them what was happening.
One of the tech guys plugged in their laptop.
I then waited about 20 minutes. After that they took the car out. All back to normal. I took the car out and floored it in all gears and it's fine.
What they think happened is when the battery was disconnected the ecu has reset and the remap didn't like the new ecu variables.
Worth noting if anyone else with a remap has trouble after the battery is disconnected.
For UK readers I can highly recommend Fearnsport, they were more than helpful
