('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
- 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.
