Spoke to an auto gearbox specialist today in Dublin who informed me that it's the transfer box that flags up that fault not the gearbox its self! Can anyone confirm this as he has quoted me a decent price for servicing the gearbox and the transfer box?

Thanks, what oil is recommended I can't get through to my local bmw dealer! Is oem oil the only way to go or is there an alternative that is just as good?

Thanks for the reply but I Live in Northern Ireland! I just need to know the correct gear oil to purchase

Yes it's a 6 speed! Gear change is 100% very smooth! The mechanic had just told me the code read gear oil worn! I just can't seem to find the correct oil! He did warn me that the oil was expensive and that cheaper oils were available but I don't want to chance it after reading some horror stories!

Hi I've recently bought an 06 3.0d sport and just for piece of mind I got a diagnostics done! It came back with gearbox oil worn! I assume this just needs an oil change? What oil is recommended?

Hi, I've recently bought an 06 x5 3.0d sport auto and I'm having the same problem. Every morning since ownership the car has gone into limp mode. I've stopped locked and re-opened the car and everything has resumed! Have you got to the bottom of your problem
