Was the chain changed at recall? If not your right to panic, you have a ticking time bomb

I would replace a timing chain at 60,000 miles as a regular service item on any engine (not just BMW) so I hope your 110,000 mile one isn't the original.

100,000 miles is the considered "lifetime" for any part so it would be well out of any warranty.

Power and torque levels have increased somewhat and constant stop/start certainly doesn't help - the guides get hammered, too.

I am considering a BMW 118d F21 with the N47 engine, produced in 2013. It has 131 000 km's on it and had not had its chain replaced.

I read that the older engine have had issues, but how have these later models (2013) worked?

Already changed the timing chain on my E46, I want to buy a car thats reliable and these timing chain issues do not sound fun. Any advice?

Anyone have any ideas on how much it would cost to have a timing belt changed before I have any issues? I guess there must be some out there that are still going strong? Even if it was not a recall effected car does a timing belt need changing every 100k miles?

Unfortunately there is no definitive answer to your question
You have a better chance than earlier models but models after 2010 have snapped

You'll be fine....forums are very good at scaremongering as I've found out. Where are all the stories of the cars that have had no issues? hardly any apparently..

Ok if it is scare mongering? What will be your comment to the same person if his chain did snap in a few thousand miles? And be honest?

Well what would be your comment if he scraps the car at 200k all fine? Personally I see it as a potential issue but I do 20k a year in a remapped 2007 n47 120d averaging 60 mpg plus now. 700 + miles between fill ups only issue ever in 125k was a failed thermostat loom. I do 7k oil changes though so certainly wouldn't buy a 100k plus car with only the standard 24k between oil changes. All cars have their issues even the 3 litre petrols. If you want reliability buy Jap and not these European models that will only guarantee their cars for 3 years.

Its all a game of chance and we the owners dont know the odds. Only BMW have an idea of the failure rates.
Yes the failure rates are likely to be 'statistically' small but if it happens to you its pretty disastrous.
The early N47 cars are now not worth that much so if the timing chain snaps it could well be an uneconomic repair.
