BMW Diesel Engines, quality engineering??????

BMW 2.0 Diesel engine as fitted in 120, 320 and 520, N47 engine March 07 -March 11

Yes the @ForageTrader loves so much .

Ours just went bang, timing chain snaps and engine finished at 69,000 miles and 5 year old full BMW service history. Having googled it I find this is a well known problem there is even a petition with over 2,500 signatures to get BMW to admit the problem.

Word on the internet is if you have got one of these get shot of it , it IS going to go bang.

Anyone else had this problem, if so how did BMW respond?

i thought the weakness was in oil pickup pipe, resulting in big ends going?
i guess oil starvation can cause either.
strange though, on friend of mine whose went, oil light never came on.

Apparently not the problem comes from a batch, albeit a large batch of crankshafts, the sprocket on the rear of this has the cogs cut at the wrong angle which puts wear on the timing chain which without much warning just snaps.

big ends went on my mates, due to oil starvation. 100k miles

BMW quality, high end brand etc is advertising hype... as with most things, it works for most people.

BMW Engine quality control and Design is not what it used to be obviously.

Didn't the very early 2.0 diesels once swallow their swirl flaps in the inlet manifold leading to terminal indigestion?

 

[Penmoel]

This is not a serviceable item, apparently the chain sometimes rattles a bit as a warning, there is no fix apart from engine out to fit a new crankshaft and chain before it goes bang. After its gone bang its a new engine.

BMW know of the problem but dont or wont do an engine recall.

Is this the engine fitted to the Freelander?

No that was the previous engine the M47

not heard of the 2,0 problems but the 6 cylinder does suffer from head failure i am surprised at bmw i have never had major problems with their products and any issues have been quickly, sorted shame on them.

Have you got one of these engines???

German cars tend to innovate well but innovation and even 'build quality' does not relate to mechanical reliability. Look at the used car reliability surveys and German cars seldom list at the top.
The six cylinder engines from 2001 to 2005, common rail state-of-the-art for the time, have a percentage with issues with inlet manifold plastic valves and turbos [not heard of head problems as such]. All vehicles can have issues where a certain percentage will fail at common weak points. But it is a game of percentages. Not all are likely to fail even at the weak point. If they do, then something is usually done about it. Eventually.

It took a number of years for LR to replace front diffs for free in Mk3 RR that were out of warranty, for instance. After over five years of production they finally brought out a new design and fitted it to all free as they failed and indeed re-embursed those that had previously paid.

If the BMW has covered 70,000 miles, even with a BMW service history using their recommended long-life oil, I wouldn't be surprised if they only paid half of a grossly inflated bill to replace the engine [hence not really contributing much at all apart from fluff]. If they can even be bothered to pretend. Many people would seek an used engine and get shot of it I'm afraid.

well it wasn't that long ago folks were amazed at a car doing 100k miles.

6 cylinder 2.5 litre yes but not a 2.0

You dont remember the cracking BMW alloy wheels that hardly ever happened until "watchdog" found thousands?

as i stated i have never had a major problem with bmw and all my alloys are cracking
