Evening all, my E91 went into BMW today for the Quality Enhancement, the girl on the desk told me that if the chain has stretched after a new part has been fitted possibly a tensioner,the the engine will need taking apart, does anyone know what is likely to be done. The car has done 107000mile btw.

Total cost for new timing chain, guides etc is several thousand pounds.

I asked the girl on the desk if it wasnt easier to just buy the car back off of me,trade is only £5700 she said no as it would still have to be done or scraped and BMW wouldnt scrap it.

Just a tensioner needed. It was done over night, now that is good service.

Our chain snapped last December (Late 2007 BMW 520D SE Touring). They have booked the car in to be checked (having explained that it now has a later replacement engine). I've PM'ed you Helix for a copy of the campaign. Many thanks.

Too little too late by BMW - not impressed.soapbox
Sold my 123d last year at 81,000 before it went bang as I had read they didn't pick up the tab at the time and it would have been scrap time or an engine from a breaker.
Still its replacement has a lovely N52 3 litre straight 6 petrol so perhaps they did me a favour!cloud9

I spoke to dealer today and my chassis number is on their list and they has booked my 08 E90 318d in for the QE on 17th June. However they said they would change the tensioners and then see if the chains has stretched. If they have the need to do the complete chains etc. My car has 94k miles on it and has started to get noisey. Others with this engine in E60's and some E90's have had the chains done without any argument etc. I have a 09 E60 and have been told that this engine is not being called in for the QE.

They were still changing bits right up to and including the new model one series in 2012/2013......my 57 plate scrapped last year... detest bmw for this but here I am in a 3 series I will get out of the loop one day.

Our 120d is on over 90k and only had the tensioner done. I wouldn't worry about it.

I had my 07 120d done last month, both chains and tensioners but then mine has cover 162k.

My wife has a 2008 X3 2.0d with 52k miles on it.

How much is it to change just the tensioner as preventative maintenance?

I think the term "quality enhancement" is some sort of joke?

Recall on an atrocious design fault would be more appropriate.

Is the "Quality Enhancement" free?

If so, I assume it needs to have a full dealer stamped history?

Yes it's free. No you don't need history. As long as your VIN is on the list, that's all that counts.

As for preventative maintenance - I'm not sure what the cost of the tensioner is (dealers understandably aren't revealing costs for the most part). But essentially it's a bolt and that, along with checking the tension of the chains, only seems to be taking a couple of hours.

Thanks for the advice above.... I called my dealer, booked in for 29th June. Got a courtesy car for 1 week, it depends if they need to replace the chain or not.

BMW bulletin here if anyone is interested - http://www.e90post.com/forums/attachment.php?attac...

Planning to test whether permitting 14 hours of work, replacing tensioner, upper and lower timing chains really represents a "Voluntary Quality Enhancement," or whether it is an open acknowledgement of a design fault in the County Court. Our chain snapped one month prior to the Puma announcement...

Have any of you done this yet?

How is everyone else getting on with this?

BMW have postponed the booking three times now. It was booked in again for tomorrow, but just had a call to say the bulletin was updated yesterday and they are now using updated\revised parts which are of course on back order. Now booked in on 3rd of Aug.

Not sure if I'm getting the run around....

They're still arsing about with it all. The problem now is that some cars that have had either a new tensioner and/or upper chain have broken the lower chain and often totalled the engine after only a few hundred miles.

The actual design is okay - it's as simple as it could be. The problem is that the chains aren't of good enough quality to cope with the high inertia forces. There are now some pretty major timing chain problems with the four cyl petrols such as in the R56 Mini - as well as the N42 and N46 and N43...........

You'll have a better quality and more substantial chain on a toilet flush.
