Would like some input from our diesel owners.

I know this sound very strange but can I please ask a few to check the following on their diesel BMW's.

If I open the oil filler cap on the tappet cover on my Z3 3.0l and my 320i I can only hear the vacuum and almost no mechanical noise. On my 330d I hear much more mechanical noise! Is this normal or do I have a problem, engine seems to be fine but when I stopped last night it was if there were some ticking noise comming from the engine, hence this check. The sound is very similar as when my engine ingested one swirlflap a few months ago. No swirlflaps on the car now.

Hope I get some input from a few of you guy's, thanks.

Don't know if this is normal but will check my 320d when I get home

@ Jenich, thanks so long, I hoped for a bit more response, maybe the D okes is all off line!

lot more mechanical noises mate....also the ignitions very mechanical, dont worry.

No matter how awesome the performance, the engine noise will always be noisier/harsher on a diesel compared to petrol. They aren't called tractors for nothing...

 

[Barkie]

Thanks all, it's just amazing how much noise there is with the oil filler cap open. Just want to make sure that I do not have something at HAND here!

Just had a listen in the oil filler cap on my 320d...it is far noisier than the petrol engines. Am sure its perfectly normal...:fencelook:

@ GPGOLD, thanks, was worried that I have some problems, good to know.

My Diesel is not a TRACTOR... its a Lion Purrrrr :rollsmile: Diesel is Noisy !!!I don't think that you should be Worried unless you notice that there is a drop in power or that the noise is different or alternates on occasions when driving.

 

[Barkie]

Thanks Dippies, feeling much better now icw this!

Yip Noisy boy, refined for a diesel IMO but clunky vs a petrol
