First step, erase fault codes and check if they come back.
Second step, remove fuel burning heater fuse (number depends on model/year) or unplug supply 2 pins connector for one minute to reset FBH.
Third step, check operation routine on IIDtool.
Fourth step, send report.
NEVER proceed a fuel priming except if any work/disassembling was made on the fuel circuit ! That should drown the heater (I know cause I've done ).

Also make sure have at least 1/4 of a tank of fuel, simple point but often overlooked I want to see the sweets before I get into your windowless van... I'm not stupid!
