Re: Anyone good with BMW's?
air mass meter,lambda sensor,coolant temp sensor would all cause the above...
also, poor wiring connections, any damp terminals,green corrocion on pins/connecters..
they have a heated lamdda system, this can cause problems too....
also, check your basics, crank breathers pipes, air pipes etc.......
Re: Anyone good with BMW's?
That's the thing with these bloody cars! To get a lambda sensor or an air mass meter costs a shed load of money (air mass meter = £170, lambda probe = £50) I have checked some oil breather pipes thinking that this might be the problem, and although there was some gunk in the pipes the problem didn't clear after I cleaned them out. It's just strange how it only gets worse when the air is more moist...
Re: Anyone good with BMW's?
I have the same motor in my BMW. It sounds like possibly the lambda sensor as you say. Are you getting any engine check lights at all?
Have a look on www.bimmerdiy.com (if you haven't already) I've found it quite useful in the past. Keep use posted if you get it sorted as I'd be interested to know myself...:)

No engine check lights at all. The BMW guys say that it's common for the E34's to smoke for at least an hour before the massive exhaust system heats up, I think different... One of them mentioned the water temp sensor too, but on the same comment he also said that, 'The excess white steam is probably the car overfuelling'. I thought black smoke meant the car was overfuelling...
What's your mpg like in your motor then Alex, circa 18mpg when driving slowly?
Re: Anyone good with BMW's?
I don't think steam will be overfuelling. Thinking about it my car tends to blow out quite alot of steam when the engines cold in this cold/damp weather...
I haven't really worked my fuel consumption to be honest but I get around 300 miles to a tank - £51 on the last fill (presumaing the 5 series tank is the same size as the 3 series?) :)
Re: Anyone good with BMW's?
So presuming that your £51 filled up the car from empty at 92.8p per litre I work out that your car gets 27mpg, which is a lot better than mine! :cry:;)
Re: Anyone good with BMW's?
Paul, do you know which coolant sensor I could order from GSF that would fit? I.e. is it the one that fits into the head I take it?
Re: Anyone good with BMW's?
Just worked out I'm getting around 25 mpg. That's driving pretty slow...
Re: Anyone good with BMW's?
Yep, still kicks the crap out of my mpg :(
Re: Anyone good with BMW's?
Sure does. I guess the best thing to do is start with the basics/cheapest suspect parts first. I take it the cars been serviced as it should have been? Failing that I think I'd go for the coolant temp sensor and see how you get on. :)
Re: Anyone good with BMW's?
Cool, well I've ordered a new coolant temperature sensor, plugs and new air filter so I'll see what difference they make if any... In all fairness though, I hate my car and want my old GTT back :cry: Although it is comfortable...
Re: Anyone good with BMW's?
I use mine as the daily hack. I actually quite like the car and it's practical and comfy as you say. I think once my GTT is back on the road I'll be using that more though! :cool:
