Lets see how she holds up.
I had injector #2 replaced twice. On third time, car was reprogrammed and codes cleared. Now, I have the SES light ON with injector #2 again. I will drop my car next Tuesday.

I have 47K miles, near the end of original warranty. I feel that BMW is placing band aid on the problem instead of solving it. They just have to add another band aid for 3K miles and after that it is not their problem, it's my problem and my money

get rid of it or buy extended warranty if you want to keep it, only 2 options

This. Sucks but BMW will not jump over hoops for you when you're past 50k with no warranty.

When you are past 50k and the same problems occurs, you will be covered. Bottom line, you need a brand new DDE, not just a reprog. Tell the SA, maybe he can suggest to BMW NA.

Yeah call BMW of NA and let them know to properly document it. BMW does have a goodwill policy for out of warranty cars.

Like 135 said, if its a reoccurring problem, they wil cover it.

I don't understand how a new DDE will fix it. Are the new DDE's better? A computer is a computer, shouldn't it be able to be reprogrammed, not replaced. it's not a mechanical unit. That's the part I dont understand.

My SA said there are no carbon build up issues. i've told my SA about the DDE but of course they can only do what BMW of NA tells them to do....

dde saga

So regarding zero adaptation issue which required dde reprogramming. Foreman handled my issue. Coordinated the loaner. Two days later. No more ses. Reimbursed my diagnostic fee that SA raped me on. Had detailed interior and exterior. Gave me a new brake job. Changed my ac belt pulley. He went out of his way to provide excellent customer service and this had made me confident in stealerships in general.

However, SES light is back on. Now what....the saga continues. Got 85,000 miles and gold extended warranty.

i just may live with the ses light.

The DDE is more than a computer. It's also the drive electronics that send signals to all the actuators, INCLUDING the injectors. Remember, the injectors fire more than once per combustion, which means several pulses per milli-second. If the drive electronics aren't robust enough (my conjecture), they will eventually die from overload.

One or more of the electronic componet(s) fail inside the DDE. that's why reprog is not helping.

One thing I'm still uncertain on:

What causes the DDE to fail; my situation was supposedly engine harness. However, others have had just their DDE replaced and it hasn't failed again.

The new DDE I believe has a different BMW part #, so should be different/revised.

Haven't been on here in awhile and came to see if what happen to my d is a common issue and run into this thread. Took my car in for service and the ses light came on durning my trip to the dealer. Have been noticing my car jerk well idling. Long story short after 5 days with a loaner I got my car back with 6 new injectors and only with 26k miles on it!! Car is still idling ruff going to have to go back.

Find out if you have the common denominator causing fuel injectors to be replaced for no reason: zero adaptation fault. Contact Customer Relations 1-800-831-1117. Every vote counts. My car is going in again on Friday. I am having success now that Foreman is involved and actually gives a dam.

Voltage regulators on the board maybe?

Heat is most likely causing these to fail, as it gets super hot in the dde enclosure and without any sort of active cooling it has a higher chance of failure.

That's an interesting theory. Not uncommon for electronics in other applications. It would be interesting to see the DDE failure rate tracked by climate areas.

We can all speculate why the DDE are failing but I think that no one here on this forum know why. Electronic components and computers under the hood are not new and unique to the Diesel.

If the new DDE have a new part number, it is likely that BMW found a problem with the DDE, revised the design and changed the part number (to avoid mixing newer DDE with older DDE).

I think you have it nailed. I live in Texas and my DDE is fine... so far, lol.

You are incorrect. The DDE for the US/CA M57 is brand new, never used anywhere else in the world.

Floyd, I'm guessing he was making a general comment and not referring to our specific DDE.

Perhaps, but even a general comment is incorrect. It's clear from the blueperformance document (and others) that most of the electronic sensors on various controls (throttle, EGR, swirl flaps, all the DEF system sensors including the NOx sensors, and a couple others) are also new, never used elsewhere.

Now, none of those have anything to do with the injectors, but ...

My comments about electronics components under the hood are in general. I am aware that our DDE and emission control are unique to North America (I posted these links: http://www.e90post.com/forums/showthread.php?t=828958 ).
