For our X5 the mileage didn't change after the first part of the recall - the EGR valve replacement
After the second part of the recall - SRC mixer, it seems like the mileage dropped with 2 mpg city driving
I'll confirm if that's true after few fill-ups

Mein Auto: 2011 X5 35d
Here are some scenarios on how much more it will cost you assuming the drop is real and you drive the car for 10 years. Other assumptions noted. I estimate it will cost me an additional $2 to $3k. So I figure that's what BMW would owe me to make me indifferent to the mpg drop. I am ignoring the time value of money for now and inflation.

Before I bought my car (I bought a used 2011 X5d) I drove it and others and noted the mileage I was getting (23 - 23.5 mpg). It was a big deciding factor in choosing this vehicle over others. I got even better than that after I bought it. Now I am getting 21. Two months after I bought it.

These are two-way data tables in Excel -- fairly easy to create.

Is there a new ECU flash? I believe ECU flash is same as software update.
I went in for recall in late july and they did 2 recalls: EGR and DEF mixer with Software update. Is there new update after that.

What a coincidence ? My car is currently in shop for oil change & my SA just gotten off the phone with me about latest software update for 335d. This update will take 5 hours which mean I'll be picking it up tomorrow. I'll post campaign# once I have my final invoice.

After few tanks I can confirm 2-3 mpg drop after the SRC mixer recall
The X5 also feels more sluggish than before
I think BMW owes us an explanation. One of the reason we got the diesel is the fuel economy which is almost gone now

I am wondering what will be the mpg if you theoretically do a straight pipe without all these complicated emission components

Wonder if it will "fix" the added fuel consumption a lot of us have noted since the last software change.

any idea what is this update about. I read in another forum that when you drive to red line there is a chance for SES. Not sure how true it is. Unless they did something about mpg I dont intend to get this update till my next oil change.

Axel61 got the same programming, it's at the very bottom of his scanned invoice in post #6 on this thread: http://www.bimmerfest.com/forums/sho...97#post7141897

What is this about?

Car was in for third oil change and new tires this week and they did a software update. Had to reinstall my coding for DVD play in motion and removal of welcome screen after update.

This is the second software update I've had in a year. After the first, my urea consumption skyrocketed and gas mileage went down from 32mpg to 30 average. This last gap between 2nd and 3rd oil change was the only one where I had to top off the Urea tank. And I had to put the small two botttles in twice. They checked the tanks at this oil change to see if I had pump issues or leaks and found nothing. And they put in just under 6 gallons, just a tad more than the reported 5.5 gallon capacity of both tanks combined. So not sure what happened but the last software update happened at my 2nd oil change.

I don't expect this software update to fix the problem. To be honest I feel like it will probably make it worse since they don't have to worry about bad press on a car they don't sell anymore. I had to pay for the urea refills in between the oil change even though when I bought the car I was told that normal operation would not require refills between oil changes. My car is a commute car so its just highway miles. The double talk between sales and service is just really starting to bother me.

I was in the process of upgrading to an M3 due to frustration with the 335d issues and a job transfer to a much shorter commute, but a combination of things gave me pause. First, the M3 was taken out of ED pricing right when I was going to order. Second, ED no longer has the two for one airfare pricing. Third, my dealer has cut their loaner car fleet in half and the last 2 visits I've been stuck in a rental. Fourth, the dealer just closed its weekend service hours so now I have to miss work time to get service and the dealer is 40 miles from my office and home. I'm going to keep the 335d at this point, but not sure if I may take a break from BMW at my next purchase.

I have confirmed a 5% or 2 MPG drop in fuel economy since the EGR recall. Just went on a 300 mile highway trip today with NO AC. While just under 40 MPG, which is good, it's still is not the 42 MPG I was able to achieve before the recall. At first I thought there was a loss of 10% but half of that was due to AC use.

Hopefully this latest update will restore the MPG. Only time will tell.

disappointing...

I have had numerous service issues on my '09 mainly related to the emissions system including a burning smell after shut off and the higher than normal usage of def. Most recently over the past 6 months the "service engine soon" light comes on. 3 trips to the dealer to "replace parts" (temperature sensor twice), the head is off the engine with new parts on order due to a carbon build-up in one of the ports. 56,000 miles and everything is still covered under warranty but this experience does not garner any confidence that the car will be less problematic if and when this issue is resolved and the next issue occurs outside of warranty. Love the power, handling, and mileage on this car, but it should not be this hard to keep a car out of the shop. Great idea, terrible execution.

Your comments remind me a lot of my truck. Not that it has had a ton of issues but that particular engine in Fords is notorious for some common problems one of which is injectors. Back when Ford still sold them then it was almost a gurantee that anytime you took the truck in for any sort of service that they would have new ECU programming to put on that was done to try and address the common issues. This went on until basically the trucks/engines were no longer sold or a period of time after they were no longer sold. But did Ford ever figure out a solution to the issues? I don't think so, I paid to put 8 injectors in just last year due to 6 failures over the span of 3-4 months.

I know Ford and BMW are different companies but the same general worry enters my head when I see problems. I must admit though that the occurrence of the same sort of problems for the BMW are nothing at all like the world of those trucks.

Some good news, at least for me! I spoke with my SA, and my car does not need the latest software update. His explanation was that my version of the EGR valve programming is inclusive of this software update, according to BMW. So for once, I apparently escape having to do it again.

It's nice to get lucky, I just hope my luck holds next time I visit the dealer, and they hook up my car to their computer!

I hope this update has some mpg gain if at all my d needs it. I used to get 34-35mpg for trip to NYC but my recent trip after update was 32. I am going to Albany this weekend and before leaving I will check tire pressure and fillup again to get more accurate reading.

Any news after the reflash on MPG? I'm doing a fairly long trip soon and want to get the most out of it (MPG, that is).

37.3 mpg

I just drove 280 miles Seattle to Pullman, trip computer indicated 36.1, hand calculation after fillup in Pullman says 37.3 mpg. I personally don't believe that there has been a loss of mileage with the recall re-programming. GPS says average speed was about 61 mph. Speeds ranged between 74 and 58. This is quite a hilly drive btw.

As I've said before, it's possible - but no-one has yet convinced me - that city driving might be lower than before. But my 'd doesn't show that.

So I just got the call about the latest open recall. Campaign # 0013130200
Tried to write down what she read over the phone: Software update for the DDE Digital Diesel Exhaust for selective catalyst reduction. I probably am missing some words or got them wrong but best I could do at work.

Before i have this update apploed, who has gotten the update and what effect did it have on your mileage?

Thx

I took my 335d in for an oil service and the service advisor informed that there was another emissions recall (I didn't receive anything in the mail after the first recall).

They described it on the invoice as an "M57 programming." They also replaced the SCR Mixer.

After driving the 328i loaner, my 335d seemed to be faster than ever. I decided to reset my my MPG right when I got on the freeway (~40 miles from Santa Clara to Santa Cruz with a climb up to 2000 feet). Now this is is a very limited mileage sample, but my MPG indicated 41.5 mpg as I came into to Santa Cruz. Very promising.
