Just in case anybody had this problem, the heater plug indicator would blink and the pending fault of over pressure in the fuel rail would show up.  I got a new pressure sensor to start at the cheapest option! Didn't make any difference so I decided next was to replace the fuel rail pressure regulator. Just before stripping things down to get the fuel rail out I thought I'd check for a possible broken wire along the route back to the ecu. Shaking the wires did cause the fuel pressure to jump around and when I got back to the ecu there was a tiny bit of white powder around these connections so I cleaned them and all is well now

wexti, would be good if you can photo the a fending area.

May be an idea for us to check it out & clean before any issues arise.

Cheers wexti

No photos sorry, but it's the connector plug where the loom entered the ecu under the wiper panel. You need to remove the wipers, then the 2 plastic panels then you can see the ecu. 2 weeks now and no problem 😊
