BMW e53 3.0i auto question

[Shauny0121]

Hello everyone. I’m new here so sorry if I do something wrong.

I just after abit of advice really

I have a 2002 X5 3.0i auto. Drives perfect no running problems at all
I brought it 6 months ago full service history. Also a receipt for a gearbox service

But since day one. When I start the car ‘trans failsafe’ pops up and will go off on its own after about 30 seconds or as soon as I pull off all gears work perfect (auto manual sports etc) with no issues to drive. The last owner said it’s been there since the gearbox service (2years ago) because the garage didn’t have a scanner to reset it because it’s ment to be ‘lifetime’ oil

This is my 3rd X5 (second petrol) 1st petty got wrote off my diesel one was perfect but the same message above came on and stayed on then 2 days later gears started slipping (like clutch slip in manual car) then low and behold about 5 days later gearbox went completely so sold off as parts.


Any advice on this would be most welcome the light shows up and goes off on it’s own (when pull off or about 30/40 seconds) but drives 100%
