E61 B5. 2 small questions (hopefully).

[ruivar]

Hi guys,

I've just sold my E39 B10 V8 after 7 years of ownership. Now I've bought myself an E61 B5 with upgraded engine to B5 S. I've got 2 small questions...

My mechanic got the wrong air filter for service. It does not fit. He ordered the air filter for an 545i. Do any of you guys know the exact partnumber of the air filter? I can't seem to find it anywhere... The car is currently fitted with a K&N filter... Not sure Alpina recommends that, though Or do they??

The exhaust flap in the muffler is stock open, so the car is very noisy at lower revs. I reckon the vacuum pipe is broken somewhere. Do you know where on the engine the vacuum pipe is connected?

I hope you can help me out

Thank you.
Rune, Denmark.

The air filter is a 535d item. It was also used on some facelift 520d.

BMW charge £100-120 but you can pay £10-20 for it instead.
