TD5 misfire / smoke

<< < (2/2)

Got it back.  Aircon is fixed.  The smoking is more of a mystery.  It doesn't look like it's the head gasket;  the only way to tell for sure is to take the head off and if you're going to do that you might as well replace it anyway.

It had a new MAF a few months back so they've swapped that for a KGU to see if that makes a difference.

They've also flashed the ECU to the most recent Land Rover map, and loaded the newest Autologic upgrade over the top.  It drives differently; the throttle is mapped more linearly, which made it feel more docile to start with, but actually the power's still there, it's just not quite as sensitive as it was.  This will probably prolong the life of the transmission.

Time will tell if the smoking's any different.
