2016年6月25日 · Mine is 2011 X5 35d (E70) with 69k miles. I saw two major warning message from the car screen as follows. 1. "Too much engine oil level" 2.

My wife's 2011 x5d just had an engine malfunction come up. I used the bimmergeeks protools app to read the error codes. Codes I got was 4BC2 Airmass flow sensor and 4B1C Fuel Filter heating activation. Has anyone had these codes come up ?

So I'm at the point I'm just going to change the sensor. But there's more issues as well here. Cleared the codes and checked them again today and 10 codes came back.
