Firstly, thanks for the help from members here. It was really useful.

So, having changed the brake switch (which didn't fix the fault) I took to Ebay to find a 2nd hand ESP module and ABS pump. Unfortunately the prices were a bit higher for the part number I needed than I first thought. On later models you can pick up the same part for about £40. For mine the going rate was about £175! (ouch). So, I contacted someone breaking a CLK 230 and they offered me the parts for £50 (result!).

The parts arrived, exact match on the serial numbers, switched the ESP module and after a bit of fun and games with a new ABS fault momentarily appearing I cleared the codes, reset the steering sensor doing the lock to lock procedure, and 300 miles later the fault appears to have been cured. No lights on the dash, no EML and the speedo works as it should.

Hoorah!

Thanks again for your help MBO members. Until next time...

Great News is it the first 10 numbers you have to match on the Controller 4SEP module?
