Hi All,
I am new to the forum and just recently bought an SLK350 which we are very happy with, however the other day he engine light came on without any warning, the fault codes were P0172 and P0175 [engine running too rich] which I reset to see if any symptoms transpired well unfortunately the light as come in again whilst my wife was driving, she was in traffic at standstill and noticed hat just before the engine revs dipped down just before the light came on, the car seems to be running fine any ideas what could be at fault I am thinking possibly the MAF? any advice would be appreciated.
