I have a B5.5, 2001, 1.9 TDI 130 BHP and it was not starting when it was colder than -10c so I changed the Glow Plugs and this sorted the problem but when I start the car in cold weather 0c or below then I get a lot of white/Grey smoke out of the exhaust and a strong smell of fumes.
If I leave the car running then it doesn't really get any better and it is a very sickly smell. When the engine is warm then the smoke is reduced but I can still feel the strong smell.
The coolant level has not gone down. I live in Norway so taking the car to the garage can be very expensive. I bought the car recently it's done 140,000 KM and has recently had the cam belt changed.
I am sure that the smoke is not from condensation & I know diesel's can be smokey in cold conditions but the strong smell tells me something is wrong. I can't feel any loss of power & car sounds ok & runs well with no warning lights. When I bought the car the engine bay had been cleaned really well. Looked like new which could be suspicious.
I changed the engine oil & filter recently & used good quality Castrol oil plus I also used a bottle of the stuff that is meant to clean out your system in the fuel tank but it doesn't seem to have made a difference.
I have read some other posts & people have suggested it could be the temp sensor on the coolant. The temp dial inside the car is constant at 90c when the car is warm & never goes over.
I also noticed that I had a very small oil leak when I changed the engine oil. I didn't notice it before because it is very small and the engine cover stopped it from dripping on the snow under the car. It looks like oil from the gear box (6 Speed Manual). I will clean the underside of the gear box next weekend and try to identify where the leak is coming from but does this sound like a big job?
