Strange Bmw e46 problem
Discussion
Evening.
Have a strange problem with 2004 E46 330d...
Here goes...
Once up to temperature, needle half way, upon giving it some beans, I get the orange coil light with DDE written beneath it.
However, it dosnt do it when the temp needle less than halfway.
If it comes on, I go into limp mode and upon switching off and restarting, the fault goes away, but sometimes not.
Like now for example, just got in it to come home from work and the light was on from the outset, but not in limp mode at all ...
Have had it code read, and the code relates to low fuel rail pressure.
I did clean the egr valve the other week,( unrelated), but just routine maintenance, and the following couple of days, it was perfect, but has now gone back to is old ways.
In the handbook, this light relates to emission fault??
I have noticed that, tonight after a 10 mile journey that the exhaust tailpipes beneath the rear bumper were really very hot to the touch.
You certainly couldn't hold your finger on them for more than 2 seconds...is this normal??
Anybody?

Seems strange, did ever cut out?
Mine cut out a few times once in traffic but never went into limp mode - turned out to be a crank sensor.
It will most likely be the second pre-supply (in line before the rail) fuel pump. You have the lifter in the tank (below the rear seats), the secondary underneath the passenger seat.
Fuel pressure at the rail should be around 4 bar IIRC.
I believe the P/N is 16117165590
Prices vary somehow from £30 to £180

Good luck!
Edit - from reading, don't get a cheap one, people replacing them after 20-30k. Best with a Pieburg item.
