Dear motor talker, for a few months now our Volvo C30 from 2007 permanently shows the error message “Stability control maintenance required. ABS works perfectly, but ESP of course no longer. Driving is so no problem, because power is full, but the Tüv will be less enthusiastic about it. I had the error codes read out in a Volvo workshop with the following result: BCM-0090 lateral accelerometer faulty signal – error code is actively ahead of DDM-8003 mirror heating power undercalculation or short circuit to the voltage source – error code is not actively ahead of PAM-E010 power supply too high voltage difference – error code is not actively ahead of SWM-0201 steering wheel angle sensor Faulty signal – error code is not actively available. The workshop would now want to replace the trans-acceleration sensor and this costs Pi times thumb 600 Euro without success guarantee. Therefore my questions: Does someone have the parts number of the sensor and can tell me where he is sitting (possibly under the passenger seat?). Would then try to get a spare part from the scrap and install this. Can there also be a connection with the steering wheel angle?
