    Hi just wondering if it's possible to re-sync the ews and dme using DIS? Have an 850 csi that has been sat for 6 years and has lost sync and maybe even the coding between them so the car won't start? If so I should get a copy of DIS tomorrow if someone could do a step by step guide. I...

    Neglected 850 csi Good afternoon all. I'm new to the forum so a brief intro... Had a few bmw's over the years and now own a tuned 535d but that's not why I'm here. Unfortunately 6 years ago my dad had to put his 850 csi into storage, one thing after another and the bmw got forgotten about. I...

    I've been quiet as I'm fuming. In Oct 2016 we fitted a replacement V12 (see pic) as the previous one had multiple failures due to sheered cylinder head stretch bolts. It ran beautifully for just shy of 11 months then slowly misfires crept in, mostly on start up. It's now undrivable due to the...

    Started up, (engine not cold) tick over a little bit low, drove for about 100 meters and could feel a definite lack of power, then a sudden judder and trans fail alarm. Stopped and turned off engine and restarted, all fine. What went wrong, any clues where to start, thanks.

    Hello, Car's overheating, getting very close to red on gauge. I was hoping it was low coolant, air bubbles. After looking closer bottom hose on radiator doesn't get hot when heater hoses are near boiling, so hoping it's the thermostat stuck, I've bought a new one. Car's currently miles from home...

    Hi all, thought it time I posted my new project! Having now run out of things to do to my 840, I couldn't resist buying another project. I'm sure many saw it on ebay and thought 'who would' but I did have many of the parts missing such as doors, wing, sunroof cartridge, full interior,ecu's...

    Just got home yesterday after being away for a month and the 850 is starting fine, but will only fire on 6 cylinders, I know there are probably numerous possibilities, but can anyone give me a pointer on where to start troubleshooting. Is there anything that can be easily checked, for instance...

    I left the 850 for a month connected to my CTEC charger, as I normally do, but the charger packed in and when I came home both batteries were totally discharged. I recharged them both, but when I stated the car I very soon had trans fail alarm. The RPM on idle was low compared to normal and when...

    I am in a dilemma whether or not to keep my 850 CI, I have owned it for 10 years now and barely use it. Although I keep it serviced, MOT'd and taxed, the miles I put on it are negligible. These machines are meant to be driven, and to be honest I do feel guilty neglecting this. My question is...

    On Saturday I made a comment on this forum that my 850 couldn't be running better, well that killed it. Upon smelling petrol, a quick peek under the bonnet and I could see fuel squirting out from one of the rear fuel lines. Less than an hour later everything was back together with new hoses and...

    Hi Guys, this was the final test of all the hard work. Ran it down the drag strip and my best time was 15.11 @ 96.77mph (crossing the line in 2nd gear lol) I wanted a 14.99 but it was never to be, so time to quit. The video attached was of another run during the day. I'm now retired from drag...
