Need help again,when driving home yesterday , engine light came up,when I got home I plugged in icarsoft and I got code P001477 and P032600. When I opened the bonnet ,I heard small knocking sound coming. Timing chain was fixed last year with MB original parts. Last month with similar knocking sound,it was a spark plug no 4 that got loosed but no engine light, after replacing and tighten the plug, noise stopped. I changed engine oil and filter and spark plugs as well last month.But the engine oil that I normally used is 5w-40, but dealer said they are not producing 5w-40 anymore and I was given sae 0w-20, hope this was not the cause of this issue. I will check the spark plug again in the morning. Then may be take the engine oil off and buy Shell oil 5w-40 .Car is w204 c180 cgi 2012.
