Various fuel related faults...

I have a problem N47 I'm dealing with.

I previously changed all 4 glow plugs a few months ago.

Initially everything was fine. However a recent diagnosis has revealed:

493F - Fuel presupply-pressure sensor, signal
4A6E - Glow plug cylinder 1, activation
4B1B - Fuel-filter heating, activation
4B1C - Fuel-filter heating, activation

I've run in depth diagnostics with ISTA-D and everything seems normal.

Seems very quick for a glow plug to go. Previously it was cylinder 2 when I changed all 4.

I didn't change the controller but beginning to think that could be the issue. Anyway to tell without taking the inlet manifold off?

Re 493F - apparently this is the sensor in the fuel feed line between HPFP and rail???

I'm guessing 4B1B and C just need a fuel filter change - no biggy.
