Pulled out of my garage yesterday and the car put itself into neutral with a message saying "Drivetrain" and something about continuation of journey (not quite sure if it said possible or impossible, I think I might have seen both after switching off and on again). Nearest BMW dealer is 20 miles away but mechanics at a garage in the village popped round with a laptop and said it was showing error codes indicating both that the EGR was stuck open and stuck closed. Not sure if they cleared something then and there but they got it driving and suggested they take it off to do a forced DPF regeneration. They've just returned the car which is apparently running fine, soot level down from 11% to 4% and no warnings on the dash but apparently they're unable to clear the baffling contradictory "EGR stuck" messages. Car is a 520d F10 (66 plate LCI, B47 engine), now out of warranty but went in for the EGR recall 18 months ago or so. Only 20k miles, usually gets a decent run a few times a month but little more than 35-mile round trips to the supermarket during lockdowns.

Has anyone come across this combination of codes before, and is it something that only BMW are likely to be able to sort out? Reason for asking that last question is that there's a place closer than the main dealer that comes recommended by neighbours as an independent specialist for BMW/Merc, apparently with all the latest diagnostics gear. They would be rather more convenient (as well as rather cheaper, I expect).

ISTA+ will allow you to get to the bottom of it

if it’s the Egr valve then they are not so expensive and very diy-able

If it's already had the egr recall, speak with BMW first, see what they say .. you might get it sorted free of charge, even if only as a gesture!

Hadn't heard of that but I gather it's software for installing on a laptop, does it do much the same as Bimmercode and Carly? How do the costs compare, and what other hardware (adaptors?) are required to connect any of these to an F10?

That's good to know, thanks, but although I've done my share of car DIY in the past I don't really fancy DIYing on a modern BMW. If it's simple enough for me to do then presumably an indy should be able to do it quite quickly and cheaply.

Having checked my notes it seems the recall was for the EGR cooler, which was replaced. The valve recall was apparently for slightly earlier vehicles.

ISTA+ is basically free
You will need to buy a cable (enet) to connect the OBD port to the network connector of the PC - costs next to nothing

ISTA+ is full BMW diagnostics

Sounds really useful. I don't use Windows but I've got an old laptop that I could stick it on. Could I trouble you a link to a download and to the kind of connector I would need so that I don't get the wrong type? It would certainly be interesting to explore the diagnostics. Can ISTA+ also be used to change settings, like allowing door mirrors to be retratracted at higher speeds?

I've got the car booked in with a main dealer anyway. I tried the nearby indy shop but they couldn't fit me in for more than a fortnight. I risked a shopping trip this afternoon and got a repeat of the "Drivetrain, possible to complete journey, full performance not available" warning. Acceleration was rubbish and I was worried it would die on me, though it reached the 60+mph needed to keep up with traffic, just got there much more slowly than normal and held the gears longer. I wonder if maybe it was doing another DPF regen. It seemed to settle down a bit after 10 miles or so (and particular after I accidentally turned off the ignition while stopped in a traffic queue - don't ask!), then on the way home it was fine and felt like it had full performance.

ISTA is essentially a diagnostics program but the ISTA+ version adds some module programming functionality

for option coding you need to use something else. Ncsexpert or something - I never tried yet - or use Carly or similar

you can find a link to ISTA on one of the USA BMW forums or look on the youtube channel of “help me diy”. This guy will send a link in exchange for subscribing to his site ......

I have used both routes but I forget the name of the US forum where the link is to be found

Thanks, there seem to be several offerings. Downloading the software seems to involve a shedload of hoops though.

Sorry - ISTA of course
It comes from a file share service in Australia or NZ

just download everything into a fresh directory then read the instructions carefully

Yes, ISTA+ (what maps - is that something else I should be looking at?).

There's a long thread on bimmerfest.com [All BMWs - Ista+ download link - no request] that talks about HTML5 errors, quota problems, cautioning about making sure you carefully read all instructions before even attempting to download and so on. There's talk about using "Megadownloader", which seems to be a Windows-only download manager (not easy for me as I don't currently have a Windows machine up and running). Indivdual file downloads seem to be working from a browser though, will grab them and see how it goes. Thanks for the tip.

Yes, ranging from under a tenner to around 25 quid. Are they all really much of a muchness?

Forget the reference to maps - was confused with a gps update conversation

Choice of tool is up to you : ISTA is a full-on diagnostic tool. It will let you solve any problem but you have to have a certain understanding of the way the car works to really use it to get to the origin of a problem

if all you want is codes, reset service and play with your folding mirrors then a Carly type may be for you

check the buyer comments for the enet cable - or buy using Amazon prime so you could return free of charge

OK, thanks very much for your help, much appreciated.
