Hi all

When I purchased my 335d it smoked a bit and I did a dpf check using ista which showed 0mbar backpressure, so guess it had been coded out. Recently had a full software update which of course wold have returned the map back
To standard and now back pressure is showing a value around 9mbar in idle.

Is there anyway to easily tell if the dpf has been gutted, as it’s definately not a replacement pipe?


Thanks
