Hi,

If you have read my older posts, I wrote about I am getting DME error on my dashboard sometimes, especially at nights.

Today I go to the BMW service, and they diagnosed my car, and said there is a problem with your valvetronic motor, and we need to check it more detailed, so you need to leave your car.

Now I am carless Do any of you have a knowledge about valvetronic system? and how it could make such a problem?

My car is 2004 3.18 CI, 7500km done. and 2.5 months old. Also with this problem fuel consuption is about 20-21lt/100km.

i think valvetronic is basically what is referred to as VANOS on some of the older cars. its the engine component that times the valves so that they fire properly and efficiently

They showed me a small motor unit, and told there could be problem about it, it is near the oil cap, under the cover. there is a small socket connected to it.

The idea behind valvetronic engines is to eliminates the function of the throttle butterfly by using an intake valve lift. In Valvetronic engine you get away with it without using a timing belt. Valvetronic has its own computer.

Do you have any idea how could it makes this kind of problem ?

It is a new car, not made too much kilometers? What could be behind this? The diagonastics expert at the service told me it is not related with software, the program gives them a error like mechanical. I am trying to find the clues.
