I shall have to dig out the last paper service record- which the dealer didn’t give me physically , but did give me a scan of. So I must have it somewhere.
seats! I have found the problem with my back and the seats- the lumbar support in them at its lowest is far, far too high for where my back wants it. Rolling up an empty wheel bag and jamming it between my back and the seat has made driving for over an hour possible without pain, which is nice if a bit Heath Robinson.
I’ve tried both front seats and it’s too high in both- so maybe this is just how Merc did it. Could both have a lower bladder that is borked? Sounds unlikely to me, but I’d love it to be something I could fix.
