Car got 45 mpg on the way to and from work for the last several days. 37 miles each way. 65mph-70mph. The last few tanks have been right about what I normally get for hand calculated full tanks (~38mpg).

TDI(s): 2009 JSW
Default

On my 2009 JSW, MFD was saying around 41-2 on my 30 mile commute to work. Now it is lucky to be 36-37. Hand calculated tank averages pre-fix were 33-38 depending on conditions. First three tanks after the fix were 29.3, 35.1(only 10 gallon fill), and 33.1 (running on fumes).

Performance wise, seems mostly back to normal (I think there was a period of retraining the DSG), although I also find myself babying it a LOT more since the economy shock. Not so many 0-60 in 8 second freeway ramp entrances and flooring it to pass grandmas.

Just information, FWIW.

Smile Just got the Gen 1 fix: impressions

Hi everyone,

I've appreciated all your posts, on this thread and elsewhere, about the Gen 1 fix and the results. They were a huge help in deciding whether to take the fix for my 2014 Golf automatic. I got the fix yesterday, and I drove the car about 60 miles immediately after picking it up. I'm not an expert or anything, but the car felt almost exactly the same to me. It had just as much pep, and by the end of my drive, on which I did about 60 mph on relatively level rural roads, I was getting about 45 MPG (according to the dash) which is a few MPG less than I got on a much longer drive a few days earlier (same speeds and terrain). So, anyway, no noticeable difference, except maybe a bit of loss in MPG. Oh well...still happy with 45 highway, especially since I love the car. Hope all you other fix-takers get good results too. I'm happy to (try to) answer any questions. For what it's worth, my VW service person at the Dealer, who was great, said they've done about a dozen Gen 1 fixes in the past few weeks and have heard nothing negative back...

I just got the Fix yesterday on 2012 Jetta with 65,500mi. I am impressed that butt dyno and overall feel is almost the same, same little cool start stumble and not really noisier. I filled up after and hand calculated before at 42.
I get up to 45 avg highway. Work commutes 45mi day mostly highway. I'll report back issues and mileage after some miles. Otherwise pleased so far, almost like; did they actually reprogram.
I did not take the buyback as that was more like wholesale price for me as some others reported, I suppose the reason is it's a basic Jetta.

2012 JSW (manual) 131k miles got the fix today. They annoyed the crap out of me with the new estimated mpg of 32 highway. I guess when I said "that sucks!" it was kinda loud because the service manager turned to see what was wrong. Got 38 mpg on the way home, about 20 miles. Most likely getting it tuned, dpf delete, etc so it doesn't really matter. Free money is already gone too for the timing, brakes, tires, exhaust...funny how that works out.

so if you don't mind.. please let us know if the mpg's dropped a lot or stayed the same after driving some highway miles and if power is changed .. Thanx!

Got my 2009 back today with the 'fix'. I'm pleased to report I'm not seeing any major changes. The engine is, perhaps, a wee bit louder, and there might be a slight difference in the way the DSG behaves, maybe holding each gear a little longer, but I'm not sure about that. There's definitely no lag, the acceleration is still excellent, and the fuel economy was normal, according to the computer, after a typical day driving around Indianapolis, including 40 miles on the freeway at higher speeds. Needless to say, I am relieved. I will report back after a few tanks of diesel. Now I'm glad I kept this great car (although the Jetta 1.4 TSI I got as a loaner was unexpectedly impressive).

Default Post-fix Observations

My bone stock 2012 Jetta Sedan with the post-fix 2.0 TDI and 64K miles is experiencing some surging and stumbling at steady speeds. It is most pronounced when the vehicle is not fully warmed up. For example, I leave work for my 30 mile commute, and about 10 minutes into the trip I go through a small town with a 30 MPH speed limit. I set the cruise in 3rd gear (MT)1900 RPM at 30 and it seems to confuse the computer. It'll surge and stumble a couple times per second, yet still maintain the speed. When I accelerate, it's smooth as silk and the power is just as good as before the fix. It also idles perfectly without a hiccup. It's not throwing any codes or at least no lights anyway. I don't own any diagnostic tools for this vehicle. After it's fully warmed up, there seems to be much less of an issue. I'm loathe to take it to the dealer if I can avoid it. Anybody else have this issue? Suggestions?

Is that only with the cruise control on?

Got a check engine light while driving home from work tonight on the interstate. Oh well. No effect on performance. Back in she goes.

I would say it is more noticeable with the cruise on, however it still occurs when I try to maintain a steady speed especially at lower speeds in lower gear. As I stated previously, it is more pronounced when the engine is not fully warmed up.

I will. I'm just going to show up tomorrow morning before work at the dealership's express service, no appointment. I can't see how it's anything that would strand me along the highway. Aside from the fix (which involved replacing glow plug module -- wasn't aware of that) they did a 150K service with brake fluid flush and replaced a torn CV joint boot. They also did the snow flap oxygen sensor recall replacement. I'm still not driving the car today. I will report back.

Completed my fix on my 2010 Gen I TDI (6sp manual - 138,XXX miles). The dealer kept the car for 3 days as they had issues with replacing a glow plug module while I beat on a 2016 Nissan Altima (CVT's are very odd transmissions with that rubber-band effect). Apparently there are two GP modules that they needed to replace before they could update the software. Also I had to replace my battery for some reason as they stated it wasn't big enough. The sales tech person did not provide a great explanation and said it had something to do with the amps of the current battery.

First impressions:
-The low end grunt is not as pronounced at lower RPM's which I miss. It's still responsive but my butt dyno feels there is less torque at lower RPMS especially when accelerating from 2,000 RPM.
-I still have the exhaust flap "hiccup" while driving around which doesn't happen too much.
-Engine Noise: I don't hear any difference in sound near idle as everyone else stated; I hear more engine coarseness when I get up in RPM's.
-Mileage: I have noticed the drive MPG readout to be more sensitive to throttle responses. The instantaneous readout shows a lower MPG under hard throttle against what it used to be. I agree that there is ~2 MPG hit (5% of 41) on MPG as I was able to take a few highway drives.

Other than that it runs just like it's supposed to.

I don't regret getting the fix at all. I would like to get a tune and keep the stock emissions equipment as I miss the lower end torque.

Anyone have any experience with getting a tune like Kerma where you can swap back to the original after their software update??
