Sorry to read of your coming together ABC.

I hope all comes good for you soon..............

Re the hesitancy raised by Raighne - have some fun with this!

The latest excuse/reason I've received from BMW UK is quote " The percieved throttle delay you have experienced while driving is in fact the result of the compliance of the Diesel engine control system and the automatic tramission with EU regulations of the particulate emissions. It only occurs in limited engine operating conditions at high torque requirements when a gear change is imminent. It is only apparent in certain driving styles."

Therefore it's my (our?) fault!! Read on...........

To continue quote, "The system builds acceleration at a rate that prevents the excessive formation of soot particles that would be generated should full fuelling be permitted. Because of this control, the throttle is actuallly applied electronically by the engine managment system and not directly by the driver. The effect is that the operation of the accelerator pedal can feel different due to the normal linear correlation between driver requirement and the throtttle application being replaced by the necessarily non-linear system control. The system applies the throttle slower than expected at first, and then builds to the drivers load requirement. It is not possible to alter the throttle application under these driving conditions, as compliance with EU regulations must be maintained"

Now its the EU's fault!!

And here is the helpful advice part!

Quote "A slight alteration of driving style minimises the control necessary and avoids the effect"

Very helpful, of course there is no actual advice as to what driving style to use! Funny (not really!) I thought I knew how to drive, I've been driving long enough, according to BMW I don't know how to drive, so there!!

Shucks...
Sounds like the transmission and engine management software are just incompatible with the high torque of diesel and the necessity to burn soot in the particle filter.
Perhaps, we should just stick to petrol (suddenly attractive again with DI)...
