Hi hope someone can help please. I’ve a 2008 ML. The fuel gauge is stuck on full. It’s not been a problem as I just make sure it’s got diesel in it but I need to drive to Spain later this year so I need to get it fixed. I looked on here and some people have said it could be a fuse or to try another simple thing with the odometer or it could be a faulty resistor.

I’m not very good with things like this so I went to my usual garage to see if they can find the fault. Having told them what I had found on here.

He has come back saying it’s the fuel feed unit and I need to buy a new fuel pump. With fitting it’s over £1000. I questioned it but he was certain I needed a new pump. Can someone tell me if this is correct or am I being stitched up?

Would be very grateful for help.
