After cleaning the heating wire through the workshop, my Volvo ran calmly and smoothly again. 14 days later and 2500 km on the speedometer more unfortunately the motor jerking again. Now I wonder if the LMM is so quickly rotted or if it is over after all. Apparently the cleaning has helped. Then it can not actually be defective or? It would hurt to replace the LMM only on suspicion. According to the workshop also the LMM was behind with error messages in the memory t. If renew – where is the best place to buy the Bosch LMM?
