330d e46 dde problem

[Trikeman]

My 330d with speed control on Saturday 120. When I accelerate to pass a vehicle the dde light go on. I'll stop and cut engine for 10 min, light is off and as soon as I accelerate hard the dde light goes on. Town driving the car is fine. Please any help out there welcome.

Thank you. I replaced all 3. Still the same. Think I will start on all common rail sensors. I had the car diagnostic checked but the operator was a bit rattled. Found 10 pressure related faults. Cleared them all on my request and checked again. No faults came up. Drove to MP and on a steep uphill the dde on Again. Took a big chance switching the ignition off in motion for 3 seconds and then on again and the dde light is of only to go on on the next uphill.

A good starting point would then be to tell us what you have already done.

OK I fitted a now mp07 filter and a 7 bar pump. The rear pump tested fine. Dde light still come on and car go into limp mode. I reset it by turning the ignition off and on say after few seconds. In town driving no matter how hard I drive no dde light.

Take the last 7 digits of your VIN and put it into realoem.com

First question, what does diagnostics actually say ?
