Anyone here experienced said burning oily smell in the cabin? It's a 1.2tsi elegance 2011 plate, 67k.
Only comes to light when the heater is on warm and drawing in fresh air (i.e. Not in recirculating mode with A/C running) standing still (lights or in traffic)
NOT when under weigh (moving :))
Nowt when heater is set below 19 degrees, or off, or with no fan running or on demist/AC, AC or recirculating.
No smell under bonnet or in boot (thought it might be exhaust coming in through the vents?)
Also tried sitting with the engine running, no heater or fan going and the windows down, still nothing but put the heater on and it's back!
ideas?
