Morning people.
Anyone else had the flexi mesh on the end of the Catalyst converter degrade and cause smell into the cab?
I have had a smell of fumes in the car from starting and then if u stand at lights etc, had it looked at at Halfords and they confirmed the mesh was corroded and full of holes. BTW Halfords prices are totally over the top, wanted £870 for new CAT. Also if you didn't know the mesh is a genuine part to be replaced and available from BMW for about £93, they wanted £360 to cut the mesh off and weld a new bit on. Fortunately as I've only had the car for 2 weeks its going back to the garage to be done.
Anyone else had experiences of this??
