Mercedes Benz E320 CDi 2004 - Sensotronic fault, code C249F - Unresolved #

Posted by John Hall on August 7, 2015, 1:10 pm

Year of Manufacture *: 2004

I have the above with the "service brake fault" light on, fault code C249F Operating time exceeded.

Has anyone had any issues with these, is there any good will from the dealer or can they be programmed out of the system ?

Your thoughts appreciated please ?

We have the same fault on an SL of similar age.
I quoted customer for a new unit, the customer got onto google and found a place called Broadspeed who said they could reset the counter. Nearly a month and loads of phone calls later they told him they could no longer do it and sent the unit back. The customer then brought a device off ebay that was supposed to allow you to reset the counter yourself ( a bit like eprom programming) but all this served to do was kill the unit completely.
I'm sorry I've been no help at all other than to let you know the pitfalls we had.

Regards,
Steve

Yes - Helpful

- To be fair i've researched a few companies who claim to reset them and the tools you mention (£20 from china), would not trust cheap tools like that when dealing with brakes !

Given the customer the news to let him think over the weekend - Saw on one forum that Mercedes "May" do a goodwill payment up to 10 year but mines over that anyway.

The search continues ....................

MB were doing these as a replacement Foc up to 10 years old.I guess this car is past it.As you have suggested yourself,you are dealing with brakes and would suggest do the job properly or not at all.The unit is around Â£900 exchange from MB.No coding reqd,but you will need diagnostics and a pressure bleeder to complete the job.

Is your customer aware that the brake pedal can fail comletely on this system when 'worn' John? ie NO brakes

I have a similar vehicle in, the customer is sensible and will have a new unit if necessary.

Does anyone know of a reputable reconditiner before I order new unit.

Thanks
