just realised I posted this in the wrong area, should be in e70 section.
had my car hooked up to diagnostic tool, the following fault codes came up. i already knew about the glow plugs, 2 were out when i bought the car i was just waiting for more to go before replacing all 6.
mechanic has recommended that i change all 6 glow plugs and the relay at the same time. he also said to replace the backpressure sensor and change the transfer case fluid.
does that sound about right?
