Since yesterday evening, the car doesn't pull anymore. The rev limiter just goes up, but speed doesn't increase. Can't go any faster than 60mp/h.

Same problem as this guy:

The outside temperature was -5°C and we did an intensive roaddtrip yesterday of almost 2 hours. It was at the end that this problem occured.


Yes tested again 1 night later. The car still has this problem, but not for the first 10 minutes, but now it does.


Torque converter?
Gearbox oil?
Something else?

I'll try to make a video.

Very difficult to provide accurate diagnosis over the Internet. But based on what you are describing, it may, unfortunately be something major (could just be low on fluid but you should have seen the leaking on the floor). With the "sealed" (no dipstick) BMW transmissions, there is little DIY that can be done. Time for a professional to look at it.

I had a transmission problem with our E39 540 with slipping in several gears. It was not much longer that I lost foward completely and the car had to be towed to a trans shop for a $5,000 US rebuild. The forward drum had cracked.

Hope this video helps.

Nobody?

I think it might be something related to your first turbo. Possibly the actuator.

Already had a problem with my first turbo, the vacuum holes were alle replaced and it was fixed.

If it was only the first turbo, the car would pull from 3000 RPM. But it doesn't pull at all.

I think it's the torque converter / gear box..you can see how it slips.

Or maybe both turbo's?

From what it looks like on the vid, i would say neither turbos look like there doing anything!! Revs fine ect so i would personally start with turbo(s)

[mistryn]

looks like the turbo actuators, there are 2 on the car.
Mine was like that it would not rev past 3k revs and would take ages to get up to 30mph and after that no power what so ever

In the end I ended up having replaced both actuators to the turbos/vac pipes and the Manifold Absolute Pressure sensor (MAP). as after the actuators had been replaced I had a slight blip arounf 2.5k revs

Now that I've seen the video, that does seem like an engine issue and not the trans. That would actually be good news.

Cant see the video since im at work but seems like you have a PROBLEMO amigo, get it corrected before any major catastrophy happens

Some people think engine, other think trans. I don't really have an idea anymore.
I thought it was the torque converter, it slips too much.
Will bring the car to the dealer today or tomorrow.

[mistryn]

Did you find out what the cause was?

[frackje]

ACTUATOR is the problem. Will be fixed Tuesday.

DPF will be removed next Friday (and remap of software according Wagner IC).

It's acting this way but you're not getting a Check Engine light?

[frackje]

No engine light indeed.

[GreekboyD]

I've seen this exact same issue before and the SES light did come on for it in that instance.
