E39 2000 525i Auto - No Reverse/Reverse Gear does not engage. Please Help!.
I am wondering if I can seek some advice (I have already searched and come across similar problems - but still hoping for some clarity) and diagnostic value.
After a week of my car being parked on the drive and not driven (because I was away on business in Europe), I came back yesterday and had the car cleaned etc ready for an evening out.
After driving for about 3 hours in the evening, I first noticed that the 'Reverse Gear' did not engage (but assumed I had not pressed the brake pedal hard enough) for the gear to engage - so i thought nothing of it and proceeded with the evening out. Around 10pm last nite, it was confirmed when I tried to back the car out that the reverse gear fails to engage and the engine just 'revs'.
All the others, P, N, D, 1, 2 engage fine.. I took the car home and again this morning (on the drive) tried to engage the 'R' but nothing happens, no shift, no 'jerk' (to indicate the car had engaged) - absolute nada.
I have been told this could be due to potentially Low Auto Gearbox Oil (but I assume this was 'sealed' for life by BMW) or also a Mechatronics Valve Body Fault?? The car was parked for a week in the cold weather..
Worst case scenario - i have been told that this could be the transmition which is ont he way out, something about a Reversing Drum?
Is the transmission knackered? Or could this just be a Automatic Fluid/Filter Issue? Broken Valve?
Money is really tight at the moment and I am hoping this sounds worse than it actually is..
Any advice from others who have experienced this/remedies/diagnostic would be extremely appreciated.
