Hope somebody out there can help as I am new to the Forum.
Have had starter motor problems on my 728i 1996 for the last 18 months and I am now on my 4th starter in 18 months.The latest one is only 5 weeks old.Same old story,key in and click!!nothing happens,call out engineer and he taps the motor with hammer and bingo!! car starts and runs for god knows then it happens again.My BMW specialist now advises that he is unable to get a replacement for the 4th time and that it must be something else.He suggests it may be the main fly wheel,worn cogs or what have you and I will be into him straight away for 6 hours labour to drop the gearbox to inspect the wheel!! and that`s before he starts. I am told by another mechanic that you can inspect the main wheel by removing the starter and turning the wheel with a screwdriver without dropping the gearbox!!
What do I do now? If, as my BMW specialist commented, that it is highly unusual for two starter motors to have the same recurring problem,why did they not think of the main wheel earlier.Could it be a bad batch of starter motors,but I would think highly unlikely.
Any comments would be appreciated!!
