I have a BMW 523 automatic, which I bought from new in 2000. It has a
low mileage (42,000) and a full BMW service history.
Following the 40,000 mile oil service, the car has been running like a
dog in the mornings.
For the first 10 minutes of driving, it refuses to go above 25 mph
(pressing the accelerator simply results in additional revs). During
this period the manual facility for changing gear is inoperable.
Sounds like the gear box is in "limp home" mode, however you should get
warnings like "transmission program" etc. Alternatively have you got it

(the car is out of warranty) offered a free replacement. All I had to
do was pay the difference between the "airflow service" and the cost of
fitting the new gearbox.
The car was off the road for a week. The gearbox was replaced. It made
The dealer suggested that I bring the car back. Whoa.
Time I think for a solicitors letter, also contact BMW.
I am not particularly inclined to fund further research (I'm £1000
down already, including the oil service).
Does anyone have any opinion (half-baked is as good as the dealer's) as
to what might be wrong?
See above - eliminate all the possible silly reasons, and you should be left
with the cause.
