BMW F20 125 - Noisy tappets?

BIMMERPOST
     Featured on BIMMERPOST.com
Hi all, Tried searching the forum for this topic but couldnt find anything. We've had our 125 auto for about a month and have just noticed that the engine seems quite noisy at idle as in, very tappety - it reminds me of a diesel engine. I only notice this sound from inside the car, listening from the outside, it seems normal, so i'm not overly worried about it, but having come from a 335, this engine does seem to be a bit noisier. Is this something that other owners have picked up?

Is it engine temperature related?

This doesn't sound right, excuse the pun. I've been driving around in a brand new 316i while i wait for my 118i to arrive in December and I've never experienced this before. And I literally started driving the 316i with 0km on the clock. Get a dealer to check this out, URGENTLY!

I want to emphasize what tkburn wrote: this is completely normal for the 125i, mine has the diesel-esque sound as well when stationary. Same goes for a Golf GTI, which engine is comparable.

I am 100% sure of this , see car and driver review below

"And when a 328i pulls up, a pronounced ticking from the injectors also gives away its identity. BMW tried hard to suppress the N20’s diesel-like injector noise with an acoustic cover and a thick rubber pad on top of the engine, but it remains somewhat noticeable."

FYI the 125i and 328i engines are identical

Common comment for the N20 in the 328i.

The 328i demo car I tried, confirmed what I'd read on the injection noise at idle. Yes, does sound a bit like a diesel.
