Hi all,

Looking for some advice on the 4 cylinder BMW engines please, preferably the diesel or would also consider petrol (if generally reliable).

Thinking of avoiding the N47 due to the timing chain horror stories. Unless I come across any examples which have already had the job done or frequent oil changes. Was there any year in particular where BMW resolved the chain issue?

I believe the n47 was replaced by the B47 engine. Does this engine have any such issues with the chain? Or any other common or expensive repairs? I have seen a 66 plate 320d EfficientDynamics model with 130k, but very good history and regular oil changes. Anything I should be wary of?

Also, what are the 320i's like from 2010-2016? Same goes with the 4 cylinder engines (petrol or diesel) with the 1 series from 2010-2016.

Looking forward to any advice. Would really appreciate it smile

N47's are a very good engine but the chain is certainly an issue. Some break at 80,000 and some do lots more.

Plenty of places do a drive in drive out chain job for under a grand now but you want proper BMW or Febi supplied chain kits, not BGA crap, FAI or anything else for that matter.

I'd always have a B47 in preference. But on N47's, if the engine is clean inside and the chains are quiet, just drive the bloody thing.

4 cylinder petrols are all crap until the B48.............the N43 is absolute ste and the N20 in the F30 is not looking that good in old age.

Buy a car that's been looked after and maintained, properly, with paperwork/invoices to show etc... No paperwork = carry on looking

We've an F31 325D with the N47, twin turbo. 105k miles on it and it's faultless. But it's been well looked after and well serviced.

My pal Chris has an F31 320D 'Luxury' with nearly 200k on it now; all original bar some of the turbo pipework and 3 new rads in less than 12 months (drives the Autobahn a lot and has had a few stones chucked through the front, unfortunately) - zero issues; oil changed every 5k without fail - uses Mann filters only and runs any 5W40 that meets BMWs LL04 specs etc

There are lots of both engines with very high miles; all down to being well looked after.

Ignore the naysayers and the tinterweb horror stories; you only ever hear the negatives, never the positives...

It's like Groundhog day on German car forums with "chain horror stories".

I must see at least 15-20 F3x 20ds every day on my commute. All working perfectly fine.
