Hi,
I was wondering if anyone could shed any light on a strange noise I keep hearing from the exhaust after a drive. I have a 57 plate GT sport TDI 170. I took it out for a drive today and came back and parked it up and left the engine ticking over. When I came round the back to listen to the exhaust it sounded raspy/deep sounding on tick over. I initially thought the exhaust might be blowing. When I put my hand near the exhaust I noticed that it was extremely hot.
After 60 seconds ticking over the noise goes and it goes back to a normal sounding exhaust. I took it out a few hours later and it did the same thing.
Does anyone know if this is to do with the DPF regenerating?
Thanks
