Default 2014 Q7 TDI Gen 2 POST UPGRADE Results

I had my Gen 2 2014 Q7 emissions upgrade scheduled to be completed on the first day according to Audi site 11/6/17. It was scheduled for 7:00 am. When arriving at the dealer they told me they couldn't complete it because the mechanics and supervisors were all in training and they would get to it late in the afternoon. On the 7th they called and told me it was done. On my way to pick it up I received another call saying it wasn't done and do I have my CLAIM number. They need the claim number to down load the fix for your specific car. That wasn't in the training!. when I got to the dealer they told me they had good news and bad. The good was the car was done, the bad was the car was quarantined until the EPA approved my specific repair results (2-3 days). while driving home in my loaner they called and said my car was now approved?? UNREAL!!! I went back and retrieved my COMPLIANT 2014 Q7TDI . The mechanic told me the ADBLUE was topped off and I will notice a slightly louder diesel sound and no more than 1 mpg loss in efficiency. I had a trip planned to the Midwest for the holiday's so I left Florida the next morning. when I crossed into GA my ADBLUE warning light went off and said I had 500 miles left. I called the dealer and they said bring it in immediately. I told them the closest dealer was in Atlanta (367 miles) from where I was located. I made to Atlanta and they looked at it for 2 hours and determined that the ADBLUE pump from the big tank to the small tank was bad but did not have the parts. They topped off the tank and said I would be good to drive it to the Midwest??? I did exactly that and arrived in OMAHA. The dealer there spent another 4 hours trying to fiqure it out since the Atlanta guys cleared all the codes. Needed a new pump just like I told them. Had to order it. 2days late I have my vehicle back and working. It is slightly louder. It accelerates much better but I am getting almost 4.5 mpg less than before. I averaged 28 mpg trailerin a boat 4000 miles this summer and now with no boat I just drove 1400 miles and got 23.5 mpg. Maybe it will get better with a new ADBLUE pump. I doubt it! Anyway I was told mine was officially the first one completed on the East coast. I hope everyone else has a better experience.

Wow, thanks for the update. Somehow I'm not surprised by your experience. As much as I want to just get the fix done to get the rest of the payment, I think I'll wait until there is more real life experience behind the resulting "fix". I had a feeling that the 1mpg loss would be optimistic, but 4.5mpg loss is terrible. I wonder what VW's response will be if this is the reality of the fix and complaints start rolling in?

The lawyers already got paid, they don't really care anymore.

EPA/CARB thought they handed enough punishment to mother VW, no need to push more there.

The judge just handled the biggest consumer/environment case in history. The feat is enough.

VW? They can’t even care less. Lawyers don't speak anymore, judge don't speak anymore, the government let it go. Why should they? LOL

You're still moaning and groaning? Wipe your tears with those 100 Benjamin Franklin bills handed to yah!

Winter diesel would account for lower mpg.

That sounds like a painful experience. I agree that winter diesel could account for reduced mpg. It will take a bunch of fill ups over time to know what effects the mods have on mpg. Thinking about it logically, it seems strange that you would have to use more fuel to produce less NOx.

That actually makes quite a bit of sense, as NOx becomes an issue in lean-burn situations. If there's more fuel, there's less NOx. However, most of the folks who have gotten the 2.0 fix aren't reporting significantly worse mileage. On the gripping hand, the 3.0 fix is fully emissions-compliant, while none of the 2.0 fixes is.

Sorry, I call BS on suddenly losing 4-5 mpg due to winter fuel. My winter/summer MPG differential has always been minimal. I agree, though, that we do not yet have a critical mass of "fixed" 3.0s from which to draw reliable conclusions. I'm in no hurry to have mine done.

Ok, then I call BS on OP’s reporting “28mpg trailering a boat” with a Q7. As for winter diesel, a roughly 10% decline in mpg in winter is widely reported. YMMV, but your own experience doesn’t agree with mine or with that of many, many posters on this site.

Assuming 10% reduction solely due to winter fuel is accurate, 10% of 28 is 2.8. He reports 4-5mpg reduction.

You are right, my experience does vary. Must be either my light winter foot or the mild winters we have up here in the Snowy North. I could understand some decline in the dead of a Northern winter when folks let their cars idle to warm up, use snow tires and drive in resistance-increasing snow and slush. Few of these conditions exist anywhere right now, though, especially in Florida where the poster with the 4-5mpg reduction lives.

But if you read, he was traveling via Atlanta and Omaha when he recorded his 24 mpg, which sounds much more reasonable to me than 28 towing a boat. Oh well...

I've never seen 28mpg out of mine even without towing, with a lightweight Cricket camper I got between 16-20mpg depending on how fast I was going.

23-24mpg is bout my average in the Q7 so far, 26mpg or so on interstates..

hand calculated, but I cant recall seeing MFD higher than 28mpg unless I was coming back down the mountains.. I got a good 40mpg coming home after a concert at RedRocks, but those situations dont count when its all downhill..

I do have big heavy all terrains which seemed to hurt fuel economy by a mpg or two, mostly in city driving tho.. when traveling highways they have a much smaller impact on fuel economy.

I am with you on that, 28 while towing something heavy seems a stretch.

The winter blend diesel fuel factor continues to have my curiosity. I presume that up here in the North, our diesel has already been reformulated for winter. I have filled up twice in the last couple of weeks. My fuel mileage remains unchanged at 28 to 29 MPG. I have my snow tires on now too. Where is my 10% dip?

Mine got done monday last, must be going deaf since it sounds the same. Performance went up, probably since adaptive got reset, mileage down because I can't keep foot from floorboarding throttle. Regens more often. Net result: glad its done, got check FEDEX Friday.

I took my 2014 Q7 to the dealer on Wednesday Nov 9th, it took them until Thursday evening to finish. There were some parts that they hadn’t ordered.

The results: The engine is somewhat louder at low rpm and idle (more diesel ticking). I’ve noticed that the turbo whistle is much less noticeable while cruising around at high load and low rpm. It seems as if they have increased rpm and lowered boost for similar power.
Overall power seems down substantially. They did make it jump off the line better, but then it is missing a bunch of midrange torque. Acceleration from 35-60 is nothing like what it used to be.
MPG has plummeted too. I used to get 28 on the highway, and now the best is 24. 5% is 1.4 mpg not 4. But even worse driving around town dropping the kids off at school, I used to get 18.5, now it’s 15.5.
Basically VW continues its shenanigans. I could handle 5% not 20%. I hope a magazine does a side by side test on before and after recall. I’ll offer up my 14 Q7 TDI Prestige sport plus for testing.

Are these hand calculated numbers or from the MFD?

28 MPG towing anything seems suspect to me.
