Could it be the DISA valve.??

It sounds like a bad Disa valve. I just replaced the same part on the wifes BMW last week. I ordered the part online for $180 and it took about 15 minutes to replace, very easy to do

Okey... Thats what i thought could be...

Which site did you get the valve from.?

Thanks.

:iagree::dunno:

ONLINEBMWPARTS.COM - they are much cheaper than most BMW places and the service is great

Wow..


It was actually 168us.. Thats very cheap..;)

Thanks John D...:)

No problem.. I'm not sure why more people don't know about this site for ordering parts. I found them about 6 months ago when I was comparing 2K in prices, overall, they saved me like $500.

what is a disa valve

I dont know enough technical english to explain it in a good way...
But, it is a valve mounted on the intake on the rivers side in the engine..

It controls the "things" that regulate how much air is being sucked into the combustion section...

Thats if i have understood it correctly..

As other things on the X, they are proned to fail, making a rattling sound...




Does anyone know if it is critically to have it replaced.?

IS there anything that can loosen, and be sucked into the engine.?

It is almost like a butterfly valve. When they go there is no tenstion on the valve and it just spins. Before I replace mine I had unplugged it for a few days to be sure that was the problem
