Is castrol the best option, usually I use valcoline or shell helix. Don't want to use wrong one because this rebuild is going to cost me £6k Thats what Ive used the last 10yrs, you have to use LL in BM's.....also 'CASTROL' is on top of the oil filler cap :D I get mine from Opie oils if you register...

Sorry to hear of your woes, as a matter of interest how many miles had it covered before failure, I only ask as I have a fairly low mileage 2018 40d (34k miles) and wondering is I should start to be concerned, I bought it with 18 miles on the clock and it’s had annual oil and filter changes. My 640...

That seems to be your problem.....are you using a generic scanner as a BMW designated one will tell you which number injector is bad....but looks like No5.....most of the time its 5 or 6

Tried the magic battery reset ??...disconnect battery for 1/2hr.

Sounds like the piezo is on its way out...happended on my X6, kept doing the same as yours is...new injector required Im afraid.

Really easy to change yourself if your a DIYer

Would never leave it that long, same as Alan....every 8k for me

Been a couple of times....goood day out

Had exactly the same happen on my 640d, mechanic has said the crankshaft is shot, 81k on the clock with full service.....to replace the engine with a reman would be 6k, as it was a 2012 I did the figures and sold it for £4200 to another mechanic who's going to rebuild the engine in his spare time, t...

Thats interesting, as it says in my handbook (2012) you need comfort access and if you do have it you can set the mirrors to fold in the idrive.....must have changed on later models???

Only available if you have comfort access fitted...otherwise needs programming as X5sport has mentioned.

Loads on the Bay.....just put part# in without the spaces.....start from £15.00

BMW had this little quirk since around 1994
