Mein Auto: bmw e46 330d
330d vibration at idle

My 330d vibrates at idle causing a really annoying vibrating sound in the dash, this goes if i give it just a little more rpm, i dont think it is a serious issue at all as i am a mechanic and the engines sounds sweet as a nut and pulls like a train, i havnt got any experience with bmw diesels at all as i work on vans. my experience tells me maybe engine mounts a bit warn but i dont want to replace parts if theres nothing wrong with them, the car is well maintained and just had a full service apart from the breather filter cus i didnt know it had one till today so will replace at weekend, also was thinking about removing the swirl flaps is this a good idea? it has done 210000 miles but it runs like a dream and has plenty of power etc no excessive turbo noise or anything like that, thanks

Hi, check vacuum leaks in lining of engine mounts and electric control valve, or try diagnostic first (control valve fault), the truth is, that leaks will never cause any error code.
