I would be obliged for details

Otherwise, have you had your dealer check for the VANOS Intermediate Valve Lever problem? This is a known PUMA fault item that causes very jerky engine behavoir including moments when the power can virtually cease to deliver.

The UK details are : PUMA 4736767 - dated March 3rd 2005 - Author, John Beckley, Master Technician.

The local dealership says they cannot find any record of this as it is in the UK.

giving you everything on my work order b/c i'm not sure what you can use:

CUSTOMER STATES TRANS HAS HESITATION AND SURGES, ACCELERATION RETARDED/CHURNING
1214710 Programming DME data status (with flash EPROM) (with Job No. 13 00 002)
115 WWBX

14466 DROVE VEHICLE INTEROGATED FAULT MEMORY IN EGS AND DME NO FAULTS PRESENT, CHECKED LATEST SIB AND SM FOUND DME NEEDING REPROGRAMMING. REPROGRAMMED DME AND DROVE VEHICLE. OPERATING OK AT THIS TIME.

hopefully this will help

I had many of these behavior problems with my 04 4.8. Last week had the car at the shop where the district BMW man determined that the problems were related to DME software and not trans s/w. They reflashed the DME and I have yet to see any of the problems reoccur. I am keeping my fingers crossed as this just seems too easy. Good luck. BTW the dealer was not willing or authorized?? to do this w/o prior district approval.

LVR, those dealers always say that. It's called laziness. All they have to do is contact BMW Australia and ask them to contact BMW UK and obtain details for the PUMA fault details. There is a system in place designed to facilitate communication within the BMW network.
