Diesel Fumes - Not Manifold!
Hi, I've had an issue with fumes on start up on my Accord diesel (2006 model) for a number of months. Particularly bad in cold weather. First thing to say is that it's not the manifold as Honda have already replaced this under warranty.
There is no smell of fumes in the engine compartment either so I dont think it's coming from the exhaust system, especially now that they've changed the manifold.
To me it seems to be related to the heater/air conditioning system. It only seems to be present when the system is running and before the car heats up. The smell dissipates (as far as I can tell anyway) when the engine reaches operating temperature.
The garage are stumped on it too. Anyvbody else experience this or is it just me? I have heard mention on other forums something about the gas assisted heater on cold start up but I cant see how that would bring exhaust fumes into the car?
