I had the recall work performed. A few weeks later I made three trips from Palm Springs to Santa Barbara within 3 weeks of each other - identical traffic conditions, weather, and speeds. I filled up at the same station for each trip.

Trip 1 - 38.5!! I was delighted! Even posted a Facebook picture to share
Trip 2 - 36.0 A bit disappointed. I had added Cetane booster thinking it would enhance
Trip 3 - 34.5 Confused. Don't know why the drop

They told me that BMW has released a new update
Again. I also took the bottom shroud
Off and saw some oil leak which they have
To fix. They also cannot seem to adjust my
Headlights, so they may replace them.

I drop off my vehicle a few days ago for DEF fill-up & my SA advises me about the new recall on 335d. I am pleasantly surprise that he is on top of campaign bulletin for oil burners.

I am enclosing both recall invoices below so that you can see for yourself what are being replaced.

#1. May 18th, 2012 - EGR Valve (Bulletin 11 04 12) ; &

#2. August 17th, 2012 - SCR Mixer (Bulletin 18 06 12)

Strange since as I recall the mixer was replaced on my car as part of a much older recall date than your date.

Any feedback on mpg improvement after the latest update?
My car is still at the dealer since the last 4 days and
hopefully the car will be done this week.
It is a good idea every once in a while to take the engine
shroud off and see if there are leaks.
I found oil leak and dripping on the shroud but was not
dripping on the floor.
So, told the dealer and fix it while it is still under warranty.
My warranty expires in August 2013, so does it make sense
to get the extended warranty??? with all these issues???

I'm starting to suspect the loss of fuel economy may be more with city driving than highway. This may explain why those of us with a larger percentage of city see a greater loss in average fuel economy.

I drove from Santa Cruz to Union City and back today and the onboard computer indicated 39.5 MPG (100% freeway with little traffic). Hard to put a number on it, but the city MPG has definitely dropped off.

Also let me know if your car feels like it pulls harder throughout the RPM band under full throttle acceleration.

Mine does feel like it pulls harder across the band post recall. But I was thinking it was pulling softer across the band prior to taking it in. I did have an SES light but it was in regards to the DEF system so not sure if that possibly was the cause in butt dyno results.

I feel the same. I have an unproven theory in that the reduced mpg's many are seeing is the result of increased fueling in particular at the upper RPM range as a result of the recall. Now that is total speculation but I would be interested to see a dyno done on a stock car post recall.

In fact Axel got his car dynoed post recall and he saw an increase in HP.

Perhaps it is more fuel even before upper rpms because my car rarely goes beyond normal driving rpms but my average for the past three takes is clearly below my normal average.

I thought Axel had his car dyno'd after he got the new Rennetech tune post recall?

If the update added more fueling in the upper RPM, this would have no impact on the drop in highway MPG that many have seen. I am taking the wild guess that fuel has been added late in the combustion cycle, to add heat in the exhaust as to reduce (burn off?) soot, which was the core issue addressed by the recall. By adding fuel late in the cycle, it does not contribute HP at the crank, resulting in reduced MPG. As I said, just a guess is totally unproven, and in typical BMW fashion, they will likely never say.

He did get it dyno'd after the recall only to see if the recall erased his flash tune, which it appears it did. His HP post recall was higher than his pre-Renntech baseline dyno and well below his post tune dyno result.

Axel seemed to be of the belief that the recall/reprogram only erased part of his tune? I believe otherwise and suspect that this emissions recall/reprogram had an influence on fueling the byproduct of which was a hp increase.

You're right and to snipe's point it is probably across the rpm band, which also explains my car's terrible mpg's both city ad highway.
