Checking 35d DDE software version in Rheingold?

[smassey321]

I am trying to use Rheingold to verify my DDE was updated after the EGR recall of 2012. I have the new version of the EGR however it looks like my DDE software is from 2010. Am I checking in the correct area of Rheingold (see attached image at bottom)?

If my DDE software is current I am pretty sure my EGR is bad. It is leaking boost and flapping around like crazy.

You can check your software i-level version from the vehicle info screen in rheingold.Then you can check min required ilevel from the document that instructs to reprogram DDE while updating to newer type of EGR.

It looks like your DDE was last programmed in 2010 but i have no idea when newer type EGR came in?

Below is the i-level E070-10-9-511 from the info screen. The recall info does not state a minimum i-level. Just the version of ISTA/P 2.46.3 or later.

ISTA/P 2.46.3 corresponds to i-level E070-12-03-503.It means it came in 2012 as you can see "12" after E070 which tells the year that version came in.

I went ahead and changed the HP EGR because that was the most likely cause. The hesitation issue is 95% gone now however mileage is still lower than I would expect so I think something still is not right. I only get 22 mpg on the highway.

The dealer did a key read Monday and is researching what i-level the software needs to be. Hopefully they will get back to me soon.

I also am seeing a drop of oil from my new red boost hose so I may still have a small leak.

Thanks for the update and kudos for your approach to diagnose this issue!!

Time for another update. As the weather warmed up, the hesitation became constant during any acceleration. After lots of back and forth, the dealer agreed something was odd with the ilevel, but did not think it was the issue. They still thought it was the transfer case. I pressed them to just update the ilevel first as that is $300 compared to $6000 for a new TC. So last week it was flashed to 2015 ilevel and the hesitation is now completely gone.

Yesterday I drove 400 miles in 95 degree heat and it did not hesitate once. Evey once in a while it is a little more jerky than I would expect when accelerating from a stop. This may indeed be the transfer case or just diesel turbo lag. Acceleration on the highway is now perfect.

Next, I will change the TC fluid to see if that changes the off the line smoothness. I also, can unplug the TC under the car and see if that changes anything. I am not against rebuilding the TC myself. Parts are available for around $300 and a rebuild is probably easier than changing the vacuum hoses on a diesel .

Just to add to the content of this thread: Under the same BMW part # and software version there may be different data files-so called "maps" or "tables". This is what "Data status" means, and it is grossly overlooked parameter by many.
