Is the exhaust new? Could just be the paint burning of if it is also has the heat shield been removed at all? Check the EGR valve and pipe for leaking. :thumb:metro said:hi, i have a 307 2004 2.0 hdi 110hp lease car
the problem being exhaust fumes coming through the vents.
it only happened after the last major service at the dealers (totally useless)
