For the uninitiated,could someone explain what 'compass' is, as mentioned in the statement.
I was the 2nd poster on the original thread in the general section. I asked my dealer to look into it, they agreed it was there, and also that it was on another GLC that they tested for comparison. Was told it was just something that happened with Merc 4x4s.
This was back in Jan 16.
I'm wondering given that I raised it with my dealer and they investigated, should I look about a set of tyres. Although my car is around 15 months old, I've only done around 8k.
