Is it number 6 if so its listed as an adjuster unit
It is actually yeah. There's a high pitched noise, sort of like a wasp sound coming from there? Any ideas?
No sure what its use is it looks like a flap so will adjust the air another name may be a Disa valve but others may confirm that .
Is it running ok ?
Is it running ok ?
mine has always buzzed, if goes after about 5 seconds after the engine is switched off, is this the same as yours?
It's most commonly referred to as a DISA valve. It adjusts the length of intake to help open the car up above 3000 rpm.
They aren't necessarily a wise part to buy secondhand and in any case the 4-cylinder one doesn't come up very often compared to the 6-cylinder one. A new one is expensive - £250 from BMW. There is a copy part by Vaico but contrary to popular belief they are not the OE manufacturer, Bosch are. I wouldn't use a copy part for an application like this.
Unless it's faulty I'd be inclined not to change it. They are well known for making noises. That said they are very easy to change, just remember to replace the o-ring.
