Engine Performance problem
2009 Mercedes Benz SLS V8 Two Wheel Drive Automatic
I have this new Mercedes s class 2009 module, sometimes it does not start, it does not matter whether in the morning or in the afternoon.
We noticed that when it does not start the fuel supply does not supply so we changed the fuel pump.
The problem continued we order for L5[ Crankshaft person position] we have also changed it the problem is still there.
We interchaged the fuel relay, same problem.
In fact we have ordered for the complete rear SAM[ FUSE BOX]
What do you think?
