520d timing chain
Hi all
Anyone had any timing chain issues on their f10? How did you come to notice and what was the course of action required? And how is it now? Sp

Is the chain supposed to sound like it's not moving smoothly and is it a persistent sound or does it come and go. I was listening out the other day and is a cold start a good or bad time to hear out for it. What mileage for you on and did you do Interim oil changes? Thanks Sp

It was more evident when the car was cold, car was serviced as standard nothing extra as it was a company car. Not sure how to describe the sound other than a rattle. I took a BMW tech for a drive and he said straight away it was the timing chain and tensioner. I think the issue is more with the tensioner than the chain |

Did you notice the noise from inside or outside the car. I noticed a noise like a chain but it comes and goes? Can't believe it's at such low mileage as well as the correct service intervals. Did you ever drive the car hard at all? I always try the warm the car up a little before I set off especially with the winter we have had. Sp

Yes I have the n47 engine I thinks it's all the torque extracted from the 4 pot possibly putting a strain on the belt or tensioner. I've heard a slight sound and it comes and goes I'll ask them to have a look and ask them to document it if they say they can't hear anything especially if it builds up to the chain eventually. I'm planning on keeping the car long term so definitely want it sorted. It's ok 45k at the moment Full service at dealer as the idrive. Sp.

Did you notice an improvement after the fix. I presume the engine sounded smoother; how was the drive thereafter? Thanks Sp

Even From cold starts to not waiting for a few minutes when switching off. As it's my own I've really looked after it. Ie from cold starts and switching off and in terms of just generally flooring..... so I'll be gutted if it's the timing chain. Might as well have driven it hard. The shame in the matter is this used to be true of the Ferraris 348 of the time, owners were scared to drive them hard incase the engine 'popped' ......... on a modern day Ferrari you can drive it out the showroom straight to the track. On a modern day mass produced German saloon I'm surprised you have to be gentle with it... Thanks for your reply jlr How's the rekindled spirits with your 5 going? Sp.

I keep looking knowing I'm not buying one Can't help Would love a cp model Individual colour and interior would be a bonus Maybe when they come down in price but then they will all be high milers and would then want the f90 with four wheel drive esp after the winters we've had...... and saves me putting winters on and off each year oh well Until then it's a 520d life lol Mine is a 2011 520d

I looked into this couple of years as my one is 2011 with the Performance pack from BMW, I believe a date exist, i.e. the N47 engines produced before mid 2011, my one was June 2011 so assumed good but you never know.
I also will love to know how to identify the issue, I am at 120k km. If you serach this forum arround 2011 few posting with details, but if you in doubt take it to your main dealer and ask for the check to be doucmented for future records. |

I think the long life oil change interval is too far apart to my liking as oil is oil and you need good quality and fresh oil circulating. I'll look into interim changes. I think yours being an lci you're ok! Sp

Some say that the f10 altogether does not have the timing chain problems as did the e60 n47 and some say that the problems are there as it's the same engine carried over. Evidently it is as owners have experienced the same e60 issues on the f10. Disappointing that a big marque such high as bmw did this and not rectify on a new model launch. One of the reasons I have keep my extended warranty and main dealer service for when this problem arises I have a leg to stand on. I will most definitely ask the dealer to log my visit and mark in the the future to carry out further check. I have just had the major oil service and the health check reported everything well. Don't know how thorough these are but will use this as well as leverage to the case should it arise. Sp

The F10 and and also 2011 520d are known to have the problem, check this video on new Tesla owner who moved from a 520d 2011 after having the chain problem, so out of order BMW never recalled cars impacted

I have spoken with the master tech at the dealership. He stated the exact same reason regarding position for safety. He also said the only way to check as you said is to take the engine out. He heard a slight noise but nothing major. He said if anything with the miles and type of driving I do he said it should be fine and to stick with the extended warranty as the manufacturer may give a goodwill on cost. Other than that I'm left to chance really as he said it could last 10,000 or another 50,000. That didn't give me much hope so just trying not to think about it and hope for the best. He also told me not to keep the car idling for long periods or warm up in the winter for 20mins before driving off. He said just start drive, which I found odd. I've also let the cars warm up in the winter before driving. He said oil pressure could increase. Anyone got any ideas on this. Sp

With your engine, I'd suggest intermediate oil changes in addition to the manufacturer stipulated ones to prolong the life of the timing chain further. |

Get the engine working, to warm it up in the most efficient way. Just let it stabilise for a few seconds and it's ready to go. Remember diesels are much slower to warm on idle, due to being more efficient. There is opinion in the motor trade that the long service intervals are contributing to the timing chain issue. Hard to prove, but as revision of parts hasn't solved the problem, oil change intervals must be considered as a factor. Plus a driving style using predominantly low revs won't help, as it appears a lot of the issue is stretched chains. Torque pulses (more dominant in the 4-cylinder diesels) could be another contributing factor. |
