a140l

Hi, thanks for looking at what is my first real plea for help on this forum. My Partners 2001 A140L has developed what sounds like a top end knock, or rattle of some sort, but it comes and goes, and bit like it's getting a partial but regular oil feed.. (or rather regular oil starvation?)...

In the A class does the "L" at the end of the numbers i.e 140L or 160L etc mean it is a Long Wheel Base? Mike
