Hi guys not been on for a while, so my 2008 535d had a weird issue yesterday seemed no matter how much I floored the accelerator it just would not pick up and seemed to be in really high gears all the time and was really slow, it had a map and stage 3 xhp gearbox map but I ran it through carly this morning and got these codes
00cf2b transmission hu19
00cf34 transmission hu19
00e09a gear lever

I cleared the codes but still the same so I refreshed the gearbox back to stock and seems a lot better I've had the xhp on for a while and never had any issues at all

Any body else had anything like this

Sounds like the exact same thing that happened to my 525xi, it sounds like your trans kicked into limp-home mode (3rd gear, IIRC). Lots of revs and no go.

You're having a communication issue. You have to find out what it is. None of the codes point to an actual transmission problem. They are pointing to a communication issue

thanks for the repliy it more tries to find the highest gear and dosnt like to change downing plant my foot it just picks up steady but would still do 70

Gotcha.
Mine would dump to limp-home mode and be practically undrivable at low speeds.

ye I think your right I have been having a issue with the fuse for the wiper they stop working till you wiggle the fuse in the glove box I'm wondering if there's a transmision fuse in there also, think dodgy connection on the wiper fuse so could be same if there is 1 there.

The card for the fuses got is useless all different to what's on my car

see I thought it was a big turbo boost issue at first as it didnt like over 2000 revs but checked all that

Did you ever figure this one out?

khanny

think it was a battery issue found out hard way tho after doing gearbox and sleeve service but forgot to reset adaptions and gearbox jumped into 2nd and melted a piston second hand engine and new battery gearbox been fine
