More precise actually calculated tank averages are the only reliable method to judge fuel economy. Welcome to tdiclub and good reading!
However, if the readings on his car (accurate or not) haven't changed to whatever it was churning out before or better, then either way it's good news. This means regardless of the actual mpg, it's the same whatever it actually is. I have also experienced the same results on my car. Mileage has been about the same for me.

ECU programming can very easily skew the dash MPG computation. Heck the cluster has an adjustment setting for that exact same reason. More along trust but verify with MPGs are concerned.

Yes if they are flashing the ECU, you have no idea if something changed for the fuel calculation. Besides that partial readings for all those little trips aren't very accurate in and of themselves. Hand calculated multiple full tank readings are best for judging anything like this.

Welp....

Looks like I am getting the exhaust modification done today...

The lady up in our titles office called me today and said Vw will not release the title until the recall is done. I bought the car 3 days before the recall was released, but the deal wasnt funded until after.

So either I complete the recall or the bank will cancel the deal because they cant get the title.

Sad panda...

Finally got my car back today. They did the oil change free of charge. Car has a different feel to it though. Might be because Iím used to the 2018 Passat they gave me as a loaner. 🤷*♂️

I haven't noticed any change from before the fix. They gave me a Jetta 1.4 tsi. I prefer my Beetle over it.

Why sad? It already had Phase 1 done and most have reported no change with Phase 2. If you are tuning nothing lost there anyway. More parts to sell off if that is the case.

I was going to postpone a little bit and milk the warranty.

Of course, there is some disagreement about how/if that would work at all.

I was also considering getting it done soon anyways because some are reporting less frequent regenerations and better fuel economy.

I just dont like being forced to do something.

But atleast for a loaner I got a 2018 TSI Passat with Kessy and 23 miles on the ticker.

That right there could entice me to get in sooner rather than later. What distances are people reporting between regens after P2?


My car regens like clockwork every 240 miles for about 11-12 minutes (monitored by SG2). Every regen, I lose about 30 miles until empty on my range indicator, and I average three regens per tank, so I'm losing close to 100 miles of range per tank in regens.

In town and urban driving I am about the same. On highway mostly driving about 400 miles between. Just had the fix done so don't know if it has changed any yet.

I drive 100 miles a day for work, 20 of those is city driving, the other 80 is all highway. Of those 20 miles in the city I have been averaging 33.5 MPG. Of those 80 miles on the highway, the lowest I have averaged was 44.2 ("spirited" driving as I call it). The highest has been 59.8 MPG. My overall average for my 400 miles of driving this week has been roughly 52.2 MPG. Not too bad!

After the dealer resolved the issues from the installation of PII, the wagon seems to function normally now. No more loss of power, weird shift points, etc. As a side note, I also had my DSG serviced at the same time as PII since I was slightly over 40K.
A little history, I purchased the 2015 Golf SE with the DSG and 23k miles in 1/2018 as a CPO from a VW dealer. I was stoked on the performance of the newer TDI's torque band (great low end) and the sport of the Golf with 225/45/17 Michelin's. I was getting 33 mpg on a few tanks (using Fuelly) because I couldn't keep my foot off the floor

With that said, I just picked up my 2015 Golf with the P2 completed. Since it has only 32k miles, they just added the second NOx sensor and flashed the ECU and DSG. My dealer said it would fix the 1-second loss of power just after it shifts from 2nd to 3rd gear, with 1/2 to 3/4 throttle when in sport mode. While I was reluctant to be one of the first few to get the P2 fix, I said go for it.

I'm interested in what people are feeling after they drive their TDI's after the P2 fix, in terms of the torque at 1/2 to full throttle in the lower RPM range, 2-3k. It might be a placebo effect, but for myself, it feels like there is less torque in the lower RPM's than pre P2. It feels similar in the upper range between 3-4k. I'm kicking myself for not recording some 0-60 MPH sprint times before I had VW perform the P2 fix. Maybe I wouldn't have noticed anything if I didn't know it was modified. The bummer part... is that the 2nd to 3rd gear shifting issue is still there

Anyone up for dyno testing?

I never knew if I could trust what the on-board computer read, however, after a hand calculation this week, it seems to be within a few .00's of what the trip computer and my spreadsheet calculated. For example; I recently completed my first full tank since PII. I filled up with 10.2 gallons of diesel ($3.16 per gallon in OH which was roughly $32.33 total). I drove 520 miles until the light came on (how I typically do). I figured there was at least another 40-50 miles or so of range until completely empty (but I did not count that portion). It came out to 50.98 MPG for the first full tank. Its pretty darn close to what the trip computer was telling me and considering I am 90% highway and 10% city driving, not too shabby.

I got my car back today in time for my lunch break. They had to keep it overnight because even though they pinned my subframe to keep it aligned, and it still threw the alignment out of whack. The steering wheel turned left, but the steering pulled right. Odd, I know.

But they corrected it today and I took it for a drive......

I would swear it is more responsive at light throttle. Before the fix, it had the slightest dead spot (almost DBW lag-like) if I barely touched the throttle, but now it just goes.

That remains to be seen...

For now, I shall remain indifferent.
