Hi i have a 520i automatic 2001 130,000miles. I'm looking for some help, last week for a reason unknown to me the traction control and ABS light decided to come on simultaneously. Then next time I look at the dashboard the transmission light has come on as well and the car is now running in limp mode. I got the car home and tried turning the engine off and back on yet the problem was still there. So next morning i thought i would try the car again and all the lights remained off for about 5 miles then just like before the traction control and ABS light came on followed shortly by the transmission. Now I have asked a few people and the suggest it could be i need to top up the transmission fluid, if this was the case why are the traction control and ABS light coming on first? I'm not sure when the transmission fluid and filter were last checked as i only got the car a year ago. But it is now on my to do list anyway. Does anyone have any input for me on what i should next?

Cheers in advance

Alex

Get your fault codes read.

Chances are is that it is a wheel sensor. These not only are used for the ABS and traction control system but are also used by the transmission as speed inputs. If it doesn't know what speed the car is doing then it can default into limp mode.

BTW you can't check or change transmission fluid. The autobox is filled for life.
Some people however do find a gearbox specialist at 100k mileage and get it changed together with the filter. Not cheap as the filter is an integral part of the gearbox bottom lid. But will be good for another 100k miles.

ZF who make the box, recommend the newer boxes in the E60 are serviced every 60k, you have the more reliable 5HP box.

Keep us posted on how you get on.
