Went to Medway Mercedes this morning to sort out the leaking radiator. The guy there was really helpful (unusual for them). He told me that 2 other w202's have had the same problem with the type of radiator that is fitted to my car,(a header tank on top of the rad), but theirs' had blown up totally and in one case, injured the driver as the hot coolant came into the car, causing burns. He then made a phone call to the MD and told me they would be impounding my car as they have been told by MB in Germany that they need to see one that is leaking before it goes bang. The result:- 1) An A160 courtesy car until Monday. 2) A brand new top of the range C class on Monday. 3) MB technicians coming from Germany to inspect my car. I was told that this could take some considerable time to sort, but who cares if I've got a nice brand spanker to run about in.
