bmw x3 diesel stalling problems?

Answer 1

I never stalled but I idled very low when my car was new (2001 530d). It took two adjustments to the timing and never had a problem again (till I blew out my turbo lol ;-)

Answer 2

Hi

First of all, with reference to the comment about the dodgy fuel, the problems were only petrol oriented, not diesel so that is not your problem.

Secondly, if you have a cloud of white smoke when you start the car and/or whilst driving then check all your fuel lines, including the injector leak off pipes, for leaks. You can normally see fuel staining on the culprit lines, and sometimes if you bend the lines you will get fuel seepage. Another problem area for seepage as such is the fuel filter seal (O ring). If fuel can get out then air can get in.

If there is no white smoke then I know the BMW diesels have problems with the EDC pump, in that the EDC pump actuator performs well under test but still causes stalling and idle problems.

Answer 3

If the fuel and air filters are OK, I would check the water separator. Water in diesel fuel is the most common reason for stalling in diesel engines. Inspecting your fuel filter should tell you if this is happening on your car.

Answer 4

hi, simple check filter...drain any water off as will clog filter and stop fuel getting through..check air filter tho this does not normally stop a diesel from working unless CAKED UP TO HELL WITH SUTTEE AND CRAP!!!!if none of this works put your hand in your pocket and give the poor thing a over due service!!!!how would you feel if you never had your lube changed????keep on top of every thing as new cars have a longer service change than old ones..but you still need to check oil,water tyres ect every week.....failing all that your DIESEL PUMP is on the way out!!!!

Answer 5

It can be a common problem at low speeds in certain cars. I have a new VW Passat and that has given the same problem when moving slowly in traffic. My brother has an Audi and that has done the same. I am hoping that minor adjustment during the first service will correct it. If it is bad though go back to the dealer and complain under warranty.

Answer 6

I'd go with possible water too. As a matter of interest, are you running on supermarket diesel (nothing to do with the recent petrol fandango)? You might want to try another, such as Shell or BP. Mine definitely doesn't like Sainsbury's low sulphur stuff, a change to Shell sorted it.

Answer 7

check the fuel system,and air intake,if the car runs OK at speed it is unlikely to be fuel contamination.but more likely to be an idle problem.if the problem occurs at all speeds then you need to check the fuel system.check if there is fuel at the injectors check that the fuel is free from water or dirt.check for any fuel obstruction.clean or replace filters clean fuel lines also the filter on the pick up pipe in the fuel tank.check fuel injectors.check engine compression for cylinder compression imbalance
