I've been getting a p115c cel now for about 2 weeks. It goes out now and then but always returns. My reading through the forums led me to believe it was a dirty maf sensor. I tried cleaning it and when that didn't solve it, I ordered a new one from rockauto for 200$. Dropped the new one in today and it didn't resolve the light. I tried clearing the cel after replacing the maf and it won't clear, even temporarily. This problem is occurring on a 2009 Cooper S. The only mod
I've done is an oil catch can. I still use the stock airbox and filter. Before I take the car in and get raped by the dealer, does anyone have any ideas on how to fix it?
