I own a 2003 W211.026 E320cdi, approximately 143k miles, currently fitted with the original SBC unit. I had the dreaded, but not unexpected 'Serivce Brake - Visit workshop' malfunction message pop up yesterday.
Using my iCarsoft i980 I read two codes on the SBC unit:
C249F - Service threshold reached
C22BD - Hydraulics fault: Pressure regulator, right front wheel.
I've cleared the codes and so far only C249F has returned.
As I suspect that the SBC counter must have already been reset, and the fact that there is indication that the hydraulics may be starting to fail, I'm inclined to replace the unit. I've had a huge quote from a local independent so I'm looking at supplying the part myself and having them fit it.
My part number as stamped on the unit is A0044319712 (Bosch 0265250045). Mercedes EPC lists the following numbers for my car: A0054317112, A0054319712 and the latest version A0084319812.
Spare Parts Store - buy car parts cheap online, car parts uk, auto parts, car spares direct offers to supply a unit that they have confirmed via online chat as being a direct replacement for around £660. This has the Bosch part number 0986483001.
I'm close to ordering but Bosch themselves https://www.bosch-repair-service.com/DE_en/EHB___for_vehicles_with_SBC_system-EHB_for_vehicles_with_SBC_system-0986483001-Mercedes_Benz don't list either my part number or any of those in the EPC as being equivalent!
Has anyone had positive experiences replacing their SBC from a supplier other than Mercedes? If so what is the part number on the replacement item?
Apologies for the lengthy post-the saving is potentially £600 but I could do without the hassle of ordering an incorrect part. Any advice is welcome.
