    Hi Guys, Yesterday I had my 840 delivered from USA. When car was delivered it didn’t start so I start it with cables (windows worked, fuel cap opened, trunk opened normally). With cables it started immediately. I drove it home 300m, cleaned it and parked in garage. I remembered having...

    I have this very annoying problem where I release the accelerator pedal whilst slowing down and the revs drop right down to almost cutting out. This is every time consistently. The car runs faultless other than this. Good acceleration and seems to want to go on to max speed on the motorways. In...

    I unlocked the door with the remote the other day, as usual the windrow dropped and I got in and went to the shop not noticing that the window remained dropped. So, this is how I've got to the conclusion that the micro switch (61311392193) may be the culprit and hopefully not the GM playing up...

    Hi all One further consequence of the recent melted wire problem that I would like to address. When starting up the temp gauge just immediately jumps to "12 o'clock " and stays there. Any ideas what might cause this? - I'm assuming that as it came on when a large wire melted behind the dash...

    Hi All, A puzzling issue with INPA. When my wife first got the 840 I bought a USB-OBD cable and a 20pin -16pin converter. Loaded the Ediabas and INPA software that came with it into an old XP laptop and all was well with the world. I could read and clear error codes in engine, gearbox, airbag...

    Hi all, Another wee problem with my beloved 840. I can only open the boot by using the key in the boot lock, the central locking won't open it. This all started a few days ago when I locked the glove compartment with the key not realising the boot would also be locked. Upon checking my...

    hi All, I have some problems with low idle, misfiring, vibrations @ 55-60mph and trying to tackle the issues. My first question is should the check engine light flash on the engine startup?

    Hi guys, The gear changes have started to become a little harsher recently when its really cold so I was thinking of having the gearbox oil and filter renewed. I wanted to get the bits myself so that I know they're definately correct for the car. I'm not sure where to get them from though. Is...

    Hi guys, need your help again. I could do with replacing the front right hand lower wishbone on my 94 840. I've checked for the part number which I think is 31121138478. Its listed at 300 dollars though! Is there somewhere here in the UK that sells them. Euro car parts have so many listed that...
