Greetings,
Need some advice again, please.
So I have a 2010 118d (remapped) MSport which has done 112k miles. It went in for an annual service at a BMW specialist who does a good job and I trust.
I was told by them that it would be advisable due to the miles and remapping to have the timing chain changed soon. Is this correct? I was quoted about £1500 as well - is this fair?
I love the car and it drives sweet as a nut with no issues - do i risk it or get it changed?
Thanks

It is a gamble I guess. There is no doubt that a number of N47 (and many other models) engines have failed due to timing chain issues however the proportion that have failed is likely to be an extremely small percentage of vehicles sold as those who are happy don't complain. My 118d with c. 127,000 miles isn't mapped, sounds sweet, drives well and I've decided that replacing the timing chain isn't part of my preventative maintenance regime whereas replacing serpentine belt, pulleys, crankshaft pulley, gearbox and diff oil etc. is. My gamble may pay off - or not! £1,500 to replace a chain etc that hasn't failed sounds expensive though.

If your specialist provided additional evidence of likely failure for your vehicle (noises etc) I would of course think differently.

Thanks for that - good advice. Maybe a 'preventative maintenance regime' is the way forward.(y)

I remember seeing several ads on eBay charging £600-700 for a full replacement. This of course was 3 years ago when I used to own an N47.

If you are to change it, I don’t think £1,500 is fair. Search around.
