Hi,

Periodically (i.e. not at all times, but quite often) by car begins to shake, felt in the entire body of the car when running idle either with the brake depressed but also with the gear selector in P.

The shaking disappers completely when the engine revs over apx 1000 rpm and comes back when the needle fall below 1000 rpm. The shaking sort of increases when the accelerator is pressed gently in P until the 1000 rpm is reached.

There does not seem to be a pattern as to when it happens (e.g. only when engine is cold).

Anyone has a clue to what that is about?


Cheers...

** Lars

Around 140.000 kilometers. Definately not the spark plugs (it's a diesel ;-).

The Check Engine light is NOT on.

I had a suggestion from another guy that it could be the diesel injector for one of the cylinders being faulty causing it to misfire.

There's a big difference between a little vibaration/shake and a misfire.

Try using a diesel injector cleaning additive - these may or may not work, some people even use a nice drop of ATF (yep Auto Trans Fluid) in the tank to suspend any crap and/or water in the system and therefore let it through the filter where it will be burned and slung out the back (water can build up in diesels quite a lot due to condensation within the fuel tank, after which it can block the fuel filter).

If the cleaners don't work then It's best to take it to a diesel specialist who will give it just the same treatment and replacement parts (BOSCH injector nozzles NOT BMW injector nozzles as some would have you believe) as BMW would but for a lower price. I used to work at a bosche diesel diagnostic center and all of the local bmw, merc, ford etc. garages used to send their customers diesel cars or pumps/injectors to us anyway (little beknown to their customers)- we had the correct equipment to deal with them.

Ahh.. Okay - thanks for the tip - I will try with the cleaning additive and see if that helps.

And Yes indeed Beel Z. diesel engines do thrive on clean filters/injectors. Although Moisture is very common in older engines; I thought with all these new electronics and dryer they did away with this problem.

I always start troubleshooting my own car from the basics then I escalate to the more complicated and hence more $$$ that is why a scan for the engine faults is essential at least to minimize guessing. Never mind trying to solve a missing engine's problem over the internet!!

I own a 2000 525 DA with 106.000 kms and the same problem has started occruring. I went to my dealer and they said they would check with their computer : the petrol I use is not faulty (comes from different stations). They also said that injectors can't get dirty os used or whatever.
It does not happen all the time but from time to time under 900 rpm whether the engine is cold or not. The car is either really shaking or just slightly quivering...
All the maintenance is BMW
I will tell you.
