We changed 3 sections of the exhaust but reused the DPF section on my 500 multijet. We then got the check engine message and dashboard icon shows in yellow. The guy who changed the exhaust says the sensor may need replacing but it was fine before the change. Has he missed a sensor connection? He says there was only one but i thought i saw a pic showing two? Anybody else had a problem after changing exhaust parts?
