Hi all,
I've been lurking as long as I've had my X5, but this is my first post. Back toward the end of last year, I purchased a 2004 E53 3.0i as a project car. The body and the engine were in pretty good shape, but she had been ridden hard and put up VERY wet for a number of years. I've just recently gotten enough done (thanks Covid
) to the vehicle that it was able to pass inspection, and get a license plate. I've been using it as my daily driver to shake the dust off and make sure there aren't any underlying problems that make it not worth the restore.
When driving at higher speeds (45mph+) if I stomp on the gas to gain a lot of speed --i.e. accelerating onto the freeway-- the DSC 4x4 light starts to flash, ABS activates, and it kills some but not all power from the engine. It's intermittent as to when this happens. It happens most of the time when on an on ramp, but sometimes it won't. When up to freeway speeds, it's fine and cruises great. Small to medium changes in throttle don't bother it.
I have both INPA and ISTA+ which I've been using to try and suss out this problem. It's not throwing any codes related to the VTG, and when driving while monitoring the wheel speed sensors, steering angle sensor and yaw sensor, all the levels seem fine and consistent with what the vehicle is doing at the moment. Transfer case fluid has been changed with the correct BMW fluid and the VTG adaptations have been reset. (The problem was there prior to the change and persisted after the change and adaptation reset). It also has a brand new battery and voltage looks great when running (13.9 - 14.3v)
So at this point I'm stumped. I can't figure out what might be making the DSC decide it needs to kick in. Anybody have any experience with an issue like this?
I hope you've enjoyed my novel
, and thanks in advance for any suggestions or advice you might give.
Cheers.
