(R)OVER 75 bmw engine
Friend of mine has a SEVENty five with a bmw diesel turbo commonrail engine which behave weird.
He all ready put 4 injectors and a new manifold measure thing in it.
The engine is sputtering willst driving on the high way constant speed. (around 2000 rpm)
Last week the engine was doing the same when he was driving in a trafic-jam the engine was stalling.
Any rovers experts around?
Please feel free to correct my bad English, i'm still learning. Your Dutch is awfull! :-)

Mate of mine had similar problems with the same car.
It was the electronic diesel pump - v. expensive

Two main problems on these
(1) The Mass Air Fow sensor gets contaminated and goes outside calibration, this normal results in the engine feeling flat and fuel consumption about
10 mpg worse than normal.
Quick test is disconnect the MAF if performance improves the MAF is at fault.
However it is more likely
(2) The in tank fuel filter comes apart -- affects both petrol and diesel models result is fuel pressure is reduced and fuel is pumped from
the right side of the tank to the left. Easy to fix once you remove the rear seat base. Lifting the seat reveals two inspection plates, open the one
on the left side remove the filter head from the tank and reassemble the filter. Take care not to damage the "O" ring -- if
"O" ring is swollen either replace it or wash it in warm water with hand soap and allow to dry.
X-part do a locking wedge kit to prevent the fault re-occurring but a small self tapping screw fitted into the bayonnet fitting will do just as
well.
Sounds simple but lack of space to work makes it tricky until you get the knack.
Some other european manufacturers have the same problem on 1999 to 2004 model years.

Yes a lot of the BMW practices introduced problems particularly Valeo sourced items.
One thing to watch for on all 75s is premature corrosion of the brake lines, some are failing MOTs after only 4 years.
Unlike the Honda-Rovers the brake pipes aren't protected by plastic coating -- nothing ten minutes with a tin of Waxoyl won't fix.
