My Q5 TDI is now averaging 22-23 mpg. Before the repair it was averaging 32 combined and almost 40 mpg highway.

How short of driving are you doing? Something is wrong if you cant do a 20 mile highway trip 60-75MPH and get mid 40's.

Wow. Our Treg only dropped from about 25 mpg to about 23.5 mpg based on the computer....no hand calcs. And some of that could be attributed to the winter conditions, winter fuel and letting the car idle more often to warm it up a little.

That is messed up. Also, not what I have generally seen from reports post-fix. Open a ticket with AoA?

No I haven’t. I’m going to reinstall the stage 2 tune.

Before my emissions fix, I averaged around 31 to 34 MPG. Since the fix it's below 30, usually around 27 or so. It seems to perform about the same, maybe a little more noise. However, I was told I would only loose 1 at most 2 MPG. For me that sucks, I hate gas stations.

I want my old car back

I found this website https://www.audiusa.com/trade-in-value
It gave me a pretty good quote for my high-mileage 2014 Q5 TDI. When I go to trade in, I will use this for leverage. Since you're not trading in, you could still use it at carmax, your Audi dealer, etc.

Tomorrow’s the fix day for me. I’ll post observations. Opinion has been so divided on the effects it has been strange to read. As one whose calculated mpg since buying stands at over 34, it will be interesting to see how the fix affects my fuel economy.

I just drove the 93 miles home from my dealer with a newly fixed Q5. Maybe I have been luckier than others, but I can’t tell much difference. The car did have higher shift points and more clatter until warm, but once warm, I found I could use my paddle shifters to upshift at the old shift points I was used to. My display showed a slightly *higher* mpg for this post fix trip (36.7) than it had for the prior tank.

Obviously, just a first take, and I’ll keep an eye on it. But I’m pleased so far, particularly since I get paid $4200 now. After I run a couple of tanks through, I’ll be reinstalling my Chipwerke to see what it does.

What does the Chipwerke do? And how is your mileage now? After driving mine for a few weeks now, it seems to have gotten better. I'm now averaging around 32 mpg with my 2014 Q5 TDI.

Default Another data point on Q5 TDI

Just adding another data point. Had my 2014 Q5 TDI "fixed" last week. Same impressions as the others. It is revving noticeably higher when cold. Once fully warm, not much is different. Seems to hold on to the gears just a bit longer. Not enough mpg logged yet to compare to my previous average. I did notice that there is a bit more delay on startup when cold - ignition is paused just a bit and there is slight bit of vibration I never noticed before the modification. Question to all: are there good options out there to just reprogram our TDI's?

So far, my new average mpg is down about 1 from the number you see in my signature. Around 33.5. Performance is much the same, except for the warm up everyone is noticing. The warm-up lasted 10 minutes today on a 70 degree day in Tennessee.

As for the Chipwerke, it is what is called a piggyback tuner. The performance gains and/or fuel efficiency are modest, maybe about 1mpg better and a little more oomph. I unhook mine whenever I go to the dealer so they don’t know I am using it. I haven’t reconnected it yet, because I wanted to run a couple of tanks through to get a new baseline. BarryT86 mentioned his wife is running the Chipwerke again and it helps with the performance.

Another option is an ECU tune. These reprogram your car’s computer to a performance spec you want. It could be original factory or it could be more performance than that. There are several companies that offer it, Malone, JR and others. These void your warranty if Audi catches you using one. You cannot simply unhook it like the Chipwerke and go undetected.

I drove about 30 miles today. I am quite happy with the fix, I must say. I particularly like how thick my wallet feels in my back pocket as I sit in the car, LOL

I had a JR Auto Tuning stage 2 tune installed before the fix. I sent the new file to them last week and haven’t heard back from them yet. Owain posted in another thread on here that Malone has been selling a lot of tunes for the 3.0 TDI’s post fix.
