Hello all,
The fault has now developed into something more regular, with the ESP/ABS system now loging faults, one for P0562 system voltage low, one for C1390 Engine torque regulation/torque reduction error and U1208 No communication with ecu/engine control unit information coherence.
I am now thinking that the ABS/ESP system could be causing the engine fault.
I have checked the ABS CAN signal & found what i beleive to be a fault on the CAN signal coming from the ABS module. WIth the ABS connector disconnected, the signal appears even, with it connected the signal is as follows. I am still having difficulties with extracting reliable fault codes from the engine ecu with the multicscan or autodiagnos.
The CAN circuits measured approx 60 ohms with both ecu's connected & 120 ohms with one connected.
