('99 323, 100k miles) Ok, so I've had a slow coolant leak issue for months now, took it to 3 different BMW independent specialists, and it is still giving me trouble. The overheating as well as the coolant tank and check engine light coming on and off every second day is frustrating to say the least. To summarise:
- slow coolant leak - mechanic couldn't find leak but replaced one old and cracked hose. No difference.
- 3 weeks ago the car stopped blowing hot air from the air con, overheated (just into the red before I switched off), and the check engine light came on. Mechanic identified broken water pump and replaced everything in the coolant/radiator system except the radiator itself (inspected and OK). Engine codes pulled as coolant leak and misfires on 3 cylinders. No diagnosis at the time on these.
- today, same thing as 3 weeks ago, with the addition of a lot of white smoke coming from the exhaust when I started it up this morning (for about 5 minutes)! Car started to overheat after about 10 mins on open road.
- also, the engine light and coolant tank light go on and off every so often. Sometimes the car idles very rough the first time I turn the engine, but then is ok if I restart.
Any thoughts?
Thanks, Colin
