After the scare stories on BBC's WATCHDOG on owners problems with high mileage BMW engines with the timing gear at the rear of the engine thought I should post this. BBC One - Watchdog, Series 31, Episode 7, BMW deny engine failures are due to manufacturing fault
The ubiquitous Mercedes OM651 4 cylinder diesel also has rear mounted valve timing gear. Part gears and one short chain [ single non duplex !] --No reports of failures-------- yet! Not sure if timing chain/tensioner failure is an engine out job or not? If it is I would expect similar 4 figure repair costs out of warranty to the BMW ones quoted in the programme. Many cars have adopted this engine configuration for a couple of reasons. One--- to lower the engine height , and 2 to keep the engine short for transverse installations such as the new A and B class. Just something to be aware of?
