335D Recall 11E-A03 Campaign

So I dutifully bring my 2009 335D in for the recall. They conduct the service. Immediately I realize a loss in fuel efficiency. My commute is very deterministic relative to fuel consumption.

Before the recall:

Fuel efficiency: 35.5 mpg
60 mph - interstate hwy - sixth gear (auto) - engine turns at 1250 rpm.

After the recall:
Fuel efficiency: 30.1 mpg (15% reduction)
Engine now turns 1500 rpm at same speed and gear.

Dealership says others are reporting the same thing. I called BMWUSA and they are looking into it. Claim they have not heard of this situation...

How is that even mechanically possible?

The recall doesn't change gear ratios.......no way would revs change at a given speed.

You could change revs by unlocking the torque converter, or by keeping it in 5th instead of shifting to 6th. Doubt either is happening on purpose.

1,250 seems awefully low, I know my X5d doesn't run that slow, can any 335's verify this, would be a quick check for the poster.

This just makes no sense so I calculated the expected RPM based on some info I found on 335d.
6th gear ratio .69
Final drive ratio 2.81
Tire 225/45-17
RPM at 60 MPH = 1567

Mein Auto: 2010 X5 3.5d
had this done today. I dropped it off at 8am and fully expected (based on comments in this thread) to not get it back until tomorrow. I get a call at 3pm saying come pick up your car. I had the oil service done, they had replace a fuse for my console 12v plug, lubed up my creaking sun roof, and did the recall all within a 7 hr period. On my service sheet is says recall 18-05-12 my X is a 2010 I believe it was built at the very end of 09 or the first of 10 and was put into service in 5/10. It states that the Mixer flap , EGR - Valve, O - ring, and a rubber seal were replaced and programmed with CAS update. Couldn't be happier with the service provided at my dealer.

I will keep an eye on it, I hadn't seen the latest post about poor mileage. I'm about to have to fill up so I will track it closely after I fill up.

I am interested in your experience as my X5 was built around the same time as yours (early 2010).

Ok so I did quite a bit of driving today. After filling up I did about 55 miles of state highway driving at an average speed of 58mph and my computed mileage was right at 30 mpg (very good for me) On the way home I drove 57 miles of mixed interstate, average speed about 68 mph, and local stop and go 45-50mph between scattered stop lights. I reset the computer before I left and got a reading of 27 mpg. This is exactly what I'm used to seeing. So as far as my first quarter tank of fuel post recall, I am seeing no drastic change in fuel consumption. All in all my car seems to be the same as before I took it in, and that is 100%.

AndyX5d - good to hear your mpg did not drop . . . what is your tire size and type . . . also do you have the third row option? Thanks

My mpg dropped about 2 mpg . . . . I am keeping a close eye on other folks' mpg experience . . . I will have mine addressed during my next service visit . . . will report on the outcome . . . around November

I have the 18" rims with the factory dueler run flats and no I do not have a third row. Also I made the same 100+ mile trip today and my computer average is staying rock steady on about 27 mph.

Thanks.

As reference - prior to this recall I was averaging 23+ mpg. Post recall work mpg dropped ~21+ mpg.

Even before the recall my mpg had started to drop. Post recall work mpg briefly increased to ~22+ mpg and then dropped back to 21+ mpg.

Driving patter remained the same - 60-70% city and 30-40% hwy. On the highway I typically do about 75-80 mph. I purchase diesel from the same Chevron station.

I have the Bridgestone Dueler (Option 214) and the 3rd row seat.

Puyo - Thanks for taking the time to run the calculations. And the tire sizes you used are what I am running. I can't explain it. They reloaded the software as part of the recall and I noticed a bunch of strange things never seen before as a result. For example: Radio was reset and had to recover settings from the fob, and current readings for MPG were reset. Without knowing the details, I wondered if there was a software parameter setting which would result in a higher engine rev. My 2009 750Li, when switched from "Normal" or "Comfort" (ride) to "Sport" results in a much higher engine rev with lower mileage.

I've had an increase in mpg. Before I consistently got 24 mpg., doing 75% driving on the hwy and 25% city. Now I'm around 25.8. This may still lower as I drive more, but I've put quite a bit on already. My commute is 50 miles round trip a day. In addition, when I was bringing in my X5 for the recall, my light went on about excessive battery drain. The dealer said it would cost $1,500 (crazy) to fix - I'm out of warranty now. I have around 54,000 miles so far. But they got approval from corporate to cover the cost 100%. No hassle whatsoever. Very happy about that. They put in a new battery, neg. cable. Now, I've just gotten the message that the urea is low. Back to the dealer.

glad they are covering it.

I dont want to know what a urea service is out of plan!

N or RV? Post postive comments on service, if you have them, in the dealer feedback forum...

My X5 is getting this recall performed now, I'll report back. I've felt my X5 to be a bit sluggish recently, not sure if I've just gotten used to the torque, but I recall it feeling quick before, now it just feels average.

We're driving it 175 miles on the interstate this weekend on a familiar route so I should be able to compare to the last trip I made (weather is similar, AC, etc.).

My wife is now driving the X5 full time and in our commute she gets high 20s and I used to get low 22s on the same commute, but she doesn't really know how to drive for best economy. I try to get to speed reasonably quick, glide at speed with minimal gas and avoid red lights.

Hopefully post recall some pep will return.
