Auxilary heater seem to work but gets blocked

**snorhyvel** · 20-01-2013,06:39 PM

I have a Touran Tdi 2010. It has an aux heater. At first it was blocked to start and gott fault codes. I reset the fault codes and unblocks it, and it works, as far as I can see fine. It produces a lot of smoke, but it heats the engine and so on. But after a couple of trips (or days) it gets blocked again. Anyone know what the problem is?

Heres the fault codes that comes with the block:
