when the car is running it makes a noise in the vanos area as if the chain is loose its kind of like a metal sound the car dont idle roughly the rpm needle is steady dont seem like i`m loosing power. do all of them make that noise or this is something i should be concerned with.
any help would be appreciated
This is obviously not good. If you can get the stuff get some BG Engine Quick clean. Add the can to the engine when the engine is at about 1/4 temp, then drive the car for 20-30 min. The more stop and go driving you do the better, this will move the VANOS through its range of movement a lot more than just staying at one steady speed on the freeway. After you are done driving the 20-30 min change the oil and refill with whatever 10-30 you like. We have fixed a few cars this way at the BMW shop I work at and saved our coustomers a lot of money since they didn't have to buy a complete VANOS unit.
I'm not sure if local auto parts stores have it or not but almost every repair shop I have worked in had it in stock so just call arround and see if they have a can. If you are in the Sacramento area you can come up to our shop, we have it on the shelf.
I have the same issue. It could be a timing chain tensioner, or just a rattly VANOS. If you have 60k or more try getting a new tensioner installed. They're not that expensive.
