Timing Chain

[JT12]

Hi All, I have a bmw x1 2013 auto. Working fine for around a year now but tried to start yesterday and it’s not turning over, looked through the oil cap and can’t see the chain spinning so believe it’s that. Am I expecting a heavy bill? In the last two years I’ve had a replacement engine put in and only 14 months or so on and now the timing chain has gone. Also would this be something I can get a mobile mechanic to do? Thanks in advance.

First you say it's not turning over ? Is the starter motor turning the engine over but not starting ?

Second When you look through the oil cap you wouldn't see the Timing chain as they are at the rear of your engine

Third You say you had a replacement engine fitted 14 months ago what condition was it in/where did it come from

Your engine has an upper and lower timing chain to change both is an engine out job so major work. If either chain is broken and the engine turned over damage will be caused to the cylinder head

If you are not capable of doing it yourself then you need the help of a good Garage
