Hello all 

My 2010 3 series estate with a n47 engine has broken down.It has been diagnosed that the timing chain has stapped and probably caused more damage.There was no warning and luckily it stapped in my driveway.Has anyone any advice on pricing to get a new engine fitted and other possibilities of it being fixed.

Any correspondence will be much appreciated.

Sadly the N47 engine seems to have a fatal flaw with the timing chains, there was a BBC Watchdog program some years back but it appears the issue is still there for many. Failures have been registered from 25000 miles upwards.

Repair cost is high as the engine has to be removed as the chain is at the back of the engine I have read that average cost is around £3k + depending on what parts need replacing. 

There are now a number of Engine Specialists who do this work so I would Google away and contact a few, I would also try the Register of BMW Specialists as they will know what they're doing and normally are much cheaper than BMW.

Good Luck
