[Artermis]

Hi all,

afraid I need some help please....

My car has thrown the flashing coil light - 4.0TDI and is in limp mode, i.e. no revs above 2.5kish rpm and loss of power.

It was fine this morning on the drive to work, happy as larry driving as normal. Needed to give a friend a lift at lunch, got in the car and flashing light and limp mode. No previous signs of issues or symptoms until failure.

Have read the codes, I only have 1 (well 2, but I don't believe the torque mount is relevant):

16620 - Manifold Pressure / Boost Sensor (G31)
P0236 - 001 - Implausible Signal - MIL ON
Freeze Frame:
RPM: 0 /min
Torque: 23.4 Nm
Speed: 0.0 km/h
(no units): 2.0
Raw, Index/Key Err.: 255 000 006
Raw, Index/Key Err.: 255 000 010
Absolute Pres.: 999.6 mbar
Absolute Pres.: 1111.8 mbar

It reads like a wiring fault as it's from 0rpm and 0 speed from the moment I turned the car on. If it was a true failing sensor i'd have expected intermittent boost faults, overboost, underboost, dropping into limp mode etc.

Can anyone help me narrow it down, please? I don't know where to find the sensors or their wiring. if it is the sensor i'm not shy of replacing a boost sensor, but again I dont know where it would be hiding.

Help... please?

Thanks! Ben
