Watchdog

Hi.
BMW never learn by their mistakes! The trusty 1990cc 4 cylinder petrol engine used in the 2000, 2002 and first 320 were robust and long lived, it went to pot with the 1990cc small 6 that was in the slightly later 320, bore wear and that dreadful multichoke carb was a pain. BMW cant make up their minds whether to use cam belts or a chain, the original chains way back were duplex but now a single chain no doubt made in China!

Did anyone see the telly last night (Watchdog?) about BMW's with M47 engines from 2007-2011 having timing chain faults from about 50K miles plus. Seems they then need an engine rebuild which costs about £5k.The fault seems to be the timing chain is behind the engine. Is it in the same place on the M47r?

ALrday a thread on this, and it effects N47 not M47 engines

Don't joke! it was pretty much a Watchdog report into the K series that damaged its reputation, assisting in the downfall of MGR

Hi.
Up to the time Hans Glas introduced the toothed belt (No it wasn't Vauxhall that was the first) virtually every car had a chain driven camshaft whether OHC or OHV, others used fibre or steel gears. A good duplex chain cannot be beaten for reliability, they are noisier and can stretch, too much stretch that cannot be taken out by the tensioner can cause the chain to "Whip" which causes wear on the sprockets which develop little hooks. These problems usually only occur at very high mileages, any owner though that ignores the noise deserves the expense of a chain, tensioner & sprockets.
There must be a major issue in the N47 if the chain is breaking, its either under-rated for the load, off centre, poor quality or inadequately lubricated.

What a shame that the M47 can cost much, much more to put right than a 1.8 K series when things go bad, incidentally they are apparently treating service claims differently if not carried out by BMW dealerships.

Really? what was lucky about losing a major uk car manufacturing facilty, along with many thousands of supply chain jobs

The written word at times has unforeseen interpretations, as is so often mentioned in the forum. The point I was trying to convey to those with M47 diesel is that MG/Rover ceased produ8ction in 2005 some two years before the reported engine problems arose.

Since the broadcast, it has also been established it's the 2007/2009 N47 and not the version fitted by MG/Rover that's affected - comment was meant reassure diesel owners, not gloat in the passing of a great and much respected British marque.

Just to reiterate the troublesome engine featured is a later generation.
Nothing to do with our trusted M47!!

For a start the timing chains were on the flywheel end resulting in expensive engine out bills for BM owners.
My heart bleeds purple juice for them
