Hello, after the warning light “Error in the motor electronics” on my 93er 850 GLT no longer went out, I was now with Volvo. There was an error with the air mass meter detected. One would first try to check the cables and contacts. If this did not lead to the problem, one would have to exchange the LMM. Cost approx. € 300,00. Now my questions: 1. Can I check the contacts myself without great technical expertise? If so, where is this part? 2. Does this estimate come about (who has ever had such a reperture in the Volvo workshop). Or should you dodge ATU or free workshops in this case – or even do it yourself? 3. Have read somewhere that the consumption is also related to the LMM. Is that true? Greetings Mathias
