Hello - I am new to the forum, having had two BMW's in the past 3 years & thought it was well worth joining. Currently I have a 525 Sport Auto E39 (Jan2003) with 55k miles on the clock and I am very sad to say it has been an absolute nightmare. I bought in in August 08 and so far it's had:
Brand New Brakes rear & front
Refurbed alloys with 2 new Michelen tyres (£250+£250 ouch)
New engine (last one blew up with 3 cyclinders & pistons frying while I was doing 60mph down the motorway)
Associated : new engine sensor, new radiator, new thermo, new maf sensor, waterpump
Finally : recon gearbox!
The point of note is the gearbox, the first gearbox would go into safe mode (a clunk then it will stay in one gear I presume third?) every so often when I was doing stop start driving. I really hoped with the new recon box this problem would stop ........ but alas it hasn't. Now reading up on the transfail safe program which I presume this is, I have seen all sorts of posts from gearbox sensors, wheel sensors, alternators, maf sensors, tranny oil changes, and of course tranny replacement needed. I have done all the expensive parts as above and am wondering what else it could be as it only happens during stop start driving (normal urban driving) rather than on a motorway. Any help would be much appreciated as the guy who rebuilt the gearbox has had it back 4 times in the last 1.5 months for more than a week at a time and it is beginning to do my head in.
