    We've ridden from Bishkek, Kyrgyzstan to Islamabad, Pakistan and no issues with the replacement pump so far. Just a quick update while I was thinking of it...

    Got as far as Jammu, India and the replacement Bosch pump died (part #: 0 580 453 453). That was about 2,500 miles of life. I stopped to fuel up and the bike would fire up after. The engine would turn over but not start. Different behavior from the original pump, which failed slowly, seeming to overheat.

    I replaced the pump with another of the same and will report back if and when it fails.

    I may be joining the dying fuel pump family soon. Started a few years ago on a hot day. Died three or four times pullng up to a stop sign. would restart but died again soon afterwords. Hasn't happened again until this summer out in Colorado. This time going down the road at 60 mph it would die and then restart. This week I was riding close to home and it died at leat 30 or fourty times on the way home. Restart and then die again. Topped of with fuel and added Chevron techtron and it would still cut out a lot but limped home. What is the lasted update on this issue?
    Any information would be helpful. Thanks, Craig

    The great state of confusion
    Do you know that it is the pump and not some other screw-up?
    (I'm just asking .... clogged injectors seem to be another <ehem> common fuel system issue :puke1 )

    Anyway, I think the best news is that if it truly is the pump that there are now aftermarket units available at better prices! Seem to be in the $40 - $70 range. Links are to ebay auctions, but there are other sources ...

    Gidday, assuming that the problem is not the fuel pump.
    It could be that one of your coils is faulty.

    I was in a week long tarmac car rally last month here in NZ (www.targa.co.nz)
    We had a similar symptom in the wee Renault Megane RS225 we were running.
    Once the car was hot we would get a miss under heavy load. There were no errors in the daignostics to show this fault. We were away from the main cities so we purchased a single coil from a car wreckers. We swapped the coil out one at a time until we removed the miss. Fixed.

    The offending coil was breaking down when it was hot and under load.

    Certainly worth a try. if you can get one. Maybe borrow one from another bike to test. I am not sure if the coil is the same for a bunch of bikes. Maybe check max BMW parts fische.

    Good luck.
