That code demonstrates that the supply pressure during startup was significantly too low (it was simply ambient pressure). Nearly 4 bar should be the supply pressure. While beginning (cranking), you can recheck the fuel pressures; the engine is not required to start. Rail pressure will inevitably change if supply pressure doesn’t increase.

You must first examine the engine code being “spit out.” Visit your neighborhood garage to have it read if you don’t have an OBDII reader. often quite affordable. DDE light can result from:
gasoline with contamination. False Fuel. Injectors are spilling too much fuel back into the tank. DDE Engine module relay failed Fuel rail pressure sensor In-line gasoline pump (there are two, so it is still possible to receive fuel at the engine but not enough pressure to run it)

Hello everyone, this morning while I was driving my 2001 530d e39, she abruptly cut out on the freeway. There was a sort of humming sound as the DDE light turned on. The light went off and she started up again when I switched the ignition off and waited for a few minutes. Just curious what the problem is, should I take her to a mechanic? Just four weeks ago, she underwent maintenance (2000miles approx)

The dde light occasionally illuminates. If I accelerate quickly while the light is on, the gearbox enters safe mode and the engine shuts off.
When I stop and restart the engine, the gearbox quickly returns to normal, and everything is good.
Nothing happens if I drive the car normally without pushing it, but if I decide to accelerate quickly, everything starts over again: the dde light comes on, the gearbox enters safe mode.
there are a variety of possibilities. The dde light indicates that a serious malfunction is occurring or that your emission is out of range. The engine and gearbox communicate with one another, therefore it’s possible that an engine problem causes the gearbox to spasm.
To find out what codes were generated and proceed from there, you must have the car diagnosed. I can look at it if you are in the Dublin-South-Wicklow area. If you are on Ireland’s western coast, Eddie from Autocar could be able to help. If you are on the north side, ACC might be an alternative. This website has information about the two.

I therefore receive an email from my SA stating that the Digital Diesel Electronics are currently being replaced (DDE).
To cut a long tale short, this past weekend I observed on iDrive that the “Engine Oil was Too High.” I physically checked with the dispstick and it was just a little bit higher. While at the dealer, the oil level was adjusted, but the car’s iDrive warning was still present. The oil sensor was replaced, but the error notice persisted. The DDE will now be replaced in accordance with PUMA.
The car is 2.4 years old with 21K miles, and other than recalls, has been great. I’m now a little concerned that Pandora’s Box has been opened and I’ll end up with excessive battery drain or other electronic gremlins. The car has been at the dealer since Monday. I’m sorry Ard:angel, but how concerned should I be that the DDE is being replaced?
