Hi guys,

I have starting issues with a 335i N55.

To be short, my mechanic have replaced the OFHG and by mistake he has shorted to ground the big red wire in the engine bay. And now the engine won't start....

Everything turn on (CIC, kombi, headlight). The starter is running too but the car doesn't start.
When the car is waked up, the electric water pump start to run (she never stop when the ignition is on) and the front spal is running full speed.

I've tried many thing to try to solve the issue.

- New battery registered with ISTA
- New IBS wire
- New + pole on the battery
- A "cloned" DME by someone (but I got the data tampered error)
- Checked all the fuse and wiring
- Reset CAS with ISTA
- Reset short counter with ISTA and Tool32
- Reset Starter protection with ISTA
- Put another engine ground to chassis


After all these thing the car still won't start.

I have the following errors code :

-00281A Absolute pressure sensor, intake pipe, electrical : Short circuit to B+
-0028A4 Throttle valve, throttle potentiometer 1, electrical : Short circuit to B+
-0028A9 Throttle valve, throttle potentiometer 2, electrical : Short circuit to ground
-0028AB Consequent reaction : Throttle valve, throttle potentiometer 1 and 2 : double fault
-0028B0 Consequent reaction : Throttle valve : Emergency operation mode active
-002937 Coolant temp sensor electrical : Short circuit to B+
-0029E0 Charge air temp sensor electrical : Short circuit to B+
-002C3F Quantity control valve activation : Line disconnection
-002C6F Charging pressure sensor electrical Short to circuit B+
-003157 Tank vent valve activation : Line disconnection
-0031E9 Electric fan, activation : Line disconnection (this one is because I have unplugged the fan because it drain the battery)
-003427 Engine-oil pressure sensor, electrical Short circuit to ground
-0036E3 DME monitoring, 5V sensor supply 2 : voltage outside valid range
-009CB5 FRM : battery exhausted
-00A0B4 CAS : Engine start, starter operation
-00A3B2 Message error (terminal status, 0x130), receiver instrument panel, transmitter CAS

And sometimes I got these too :

-00378F BSD message IBS : missing
-003446 BSD message oil condition sensor : missing
-00378F BSD message electric coolant pump : missing
-003BC7 No message Dme receiver, CAS transmitter

Someone can help me please ? I don't know what to do now.....
Thanks you !!!
