Hi 306 turbo diesel is running fine and it is due a service (just waiting for some warmer weather), just looking for conformation on a little problem that has started over the last few weeks and that is, when I pull away from a stand still then I get brownish greyish smoke from the exhaust, or if I change down and pull away on the motorway i get the same smoke, I am thinking this is the air filter, anyone agree or are you thinking something worse? ok I'm a cold arsed git and I should go out and do it, but spring isn't far away is it? any advice would be much appreciated Gordon :-)
