I recently (3 months ago) became the proud owner of a CLK 500 (W209) – its 4 years old 37k miles, FMBSH and I bought it from MB Croydon and it came with 1 year Used Car Warranty - tier 1 (whatever tier 1 might mean).
I have written confirmation of the warranty but never received the full booklet and apparently it was ‘not available’ but would sent to me ‘shortly’ – sadly it has never arrived.
Unfortunately the car has now suffered the radiator fault causing water to leak into the ATF and then into the auto box
- as described and discussed elsewhere in the forum. This has been diagnosed by my local dealer - MB Brighton – who are in Portslade, Sussex.
Now the questions:
1) MB Brighton say that next week that are going to put in a claim to MB, the impression I got was if MB rejected the claim then they would claim on the Used Car Warranty – they seemed vague as to whether this problem would be covered by either MB or the Warranty. I have got the wrong end of the stick here or is claiming on MB before the Warranty the usual thing to do? Why not claim on the Warranty that’s what its there for?
2) Does anyone know what the Used Car Warranty actually covers – I haven’t managed to find anything on the MB web site – any link to an electronic version of the document would be very much appreciated
3) If MB and the warranty reject the claim what next, as MB Brighton want to replace the radiator and auto transmission I would expect the cost would be several thousands – I really don’t want to stump up for that. Would it be enough just to get a new radiator fitted and flush the auto box – i.e. hope any damage to the auto box is minor?
4) I know this is a bit open ended but are there any other known problems/‘time bombs’ in the W209 – e.g. if the radiator had been changed earlier it would have been a much cheaper job than replacing the auto box
Thanks very much for any help or insights you can provide
