Hi lads,
Maybe you lot can help! I have a 320d SE Automatic.
On Saturday, i was late for work and was therefore driving quicker than usual, pushing it quite hard but nothing serious. I shifted across to DS to overtake a truck, hit the kickdown on the accelarator and NOTHING!!!!
I had absolutely no power for about 30 secs, it was just cruising at about 55mph and simply would not accelerate! It was like the car/computer had taken over and was refusing to do what i asked. I tried shifting back to D then DS again - still no power!!! :mad:
It was even worse becos i had a ten year old Nissan Micra up my arse by now and i simply cud not overtake the truck!!???!!
After a short while, it came back to life and i cud drive it as normal. Anyone know what happened or experienced this themselves?? What should i do?

Sounds like the turbo wouldnt work properly

Best have you dealer hook it up and see if there are any errors listed

Wow! Not a good position to be in. Thankfully all is ok.
Yeah, I agree with Fleet and take it to your dealer for analysis.
I would have thought that the engine on its own would have been able to do something without the turbo boost.

@zola&osgood: As I know, there´s given sometimes trubles
with the DPF (particle-filter) .
This have to be burn free from time to time, at this moment the
software or control-systems put the power low and you haven´t got
so much passge, if You push the pedal down. It takes only a pair of
seconds, but this will be enough for a short time with lower engine
power.

That has happened to me before but with a mini cooper. There would be times where there would be no throttle response. Never questioned it as it always went back to normal, but it did happen 3-4 times.

In your case it could also be a software-problem which will be away with a new version of it.
Sometimes the part air-flow meter works wrong or not correct and give incorrect values further to the board-computer, which steer all engine-functions.

Exact and in some case the problem occurs only once....

When i was working at BMW engineering center (development of electronic device controling the automatic gearbox, the so called "Fahrstrategy") there were sometime a call of the main BMW dealer at Munich(located 400 m away from the FIZ) with a customer which had similar problem. there were no diagnostic error stored.

I mean somes guys in the department know exactly that the software is not "bugfree"...

In any case i would go to my dealer and ask for a diagnostic.
Of course a "hardware" problem is still possible (flow meter or boost pressure signal lost or any collision of signal transmitted trough the CAN bus)
