Default 2.0 Gen 1 post fix impressions, issues, etc.

I curious to know how people who got the emissions fix for the Gen 1 2.0 TDI feel about how it has changed their car. Drivability, performance, fuel economy.
Please post your experiences.
This is mine so far after the fix last week.....2014 Jetta TDI automatic.
The fix itself went well in the time frame they said it would.
Right off I noticed more engine noise. Just sounds rougher and more rattley.
Low end torque is definitely reduced. That instant pin you back in the seat response is history.
At highway cruising speed the rpms seem to be a touch higher. Maybe only 100 or so, but noticeable. The auto trans does seem to shift differently throughout the spectrum too.
Fuel economy has stayed about the same. If it is lower it's not by much. Well within the 2MPG decrease that VW stated.
It's still not a bad car by any means. Just different. Not a whole lot, but enough to be noticeable.

Our 2010 DSG has been done for nearly 2 weeks now, and everything you stated is exactly what I have noticed too:

More 'diesel engine' purring sound at low RPMs when beginning to accelerate.

Reduced torque at acceleration from standing still. Although, you can get it to launch like it used too, you just have to mash down further on the pedal. Once the car is moving down the road, I don't really notice any difference in torque when I need to accelerate quickly, maybe a slight delay from before(?), but it seems to only be that way when you take off from a full stop.

RPMs definitely seem higher than they used to be when cruising at the same speed before the fix.

No change in fuel economy that I can tell. Still averaging 37.x gal/mi.

Trans does shift weird sometimes. Also, have you noticed how there seems to be higher RPMs when you shift it into gear from Park? I know this sounds strange, but it seems that when I shift it into Reverse to back out of the garage in the morning, the car has a stronger 'pull' wanting to launch out harder than it used to. I think it's because the RPMs are higher when I put it into gear than they used to be???

As the DSG gear ratios did not change, and there is no torque converter, how can the revs be slightly higher at cruising speed?

No idea. I just know it sounds that way compared to before and it doesn't sound healthy. For my car it doesn't matter anyway, since everything they did will be ripped out and re-tuned by the end of this week. All of the parts are now here in my shop, and starting on it tomorrow morning.

Stay puff, was your car tuned and returned back to stock to get the fix? That is what I am contemplating doing. A lot of hassle but the wife wants the fix money. I'm just worried about what VW is going to do to it that maybe I can't get it back the way it is now. Let us know how it goes.

No, I decided to wait on tuning and replacing the exhaust (before the scandal) and of course when the scandal broke, I'm glad I did. I also had purchased one of Andrew's original Pureflow/Containflow kits and timing belt shields too when he came out with them. Was planning on doing everything at once during the Fall of 2015 when I had more time, and then when the news broke I just put everything on hold. I knew any mods would make my car unqualified for the fix, if there would be one, and so I've just been maintaining everything to the max to make sure nothing broke in the system until I could get it scheduled. I wanted the money too, like everyone else, but more importantly I wanted those stickers and the car in the database as being compliant.

That's very interesting. If you had taken your car to the dealership I went to, your experience would have been different. They asked me 2 very specific questions when I arrived: Does the car have a CEL on? Have you modified the car in any way? Volkswagen has given very clear instructions on this and they are written in our booklet too. It's awesome that your dealership didn't give a rip about it, but I would not expect that from most of the other dealerships.

One interesting issue could be if you bought your car used and have no idea of any tune or mods.. If the dealer ask you "does the car have any mods" some people may honestly not know if they bought a few year older car..what then?? as I bought my car used (rebuild title) Not knowing the original owner..My car really seems to have great torque.. it may have had a tune done back in 2011 from the original owner..don't know cause have not driven another 2011 same as mine (6mt).. my 2000 jetta has a RC2 tune and you can really tell ( especially with all the smoke when floored!)

And that may be the reason why some dealerships aren't too concerned. In the case you mentioned, you would just simply tell them you don't know. If it turned out to be modified, you would really have no way to return the programming to stock. Since they're going to be reflashing the ECM anyway, I really don't understand the big deal behind the ECM aftermarket mods. I can see if there are physical mods that could cause problems and conflicts with the new factory modification, but software mods? To me it shouldn't matter if it's a stock program or aftermarket program. It's going to be deleted anyway.

Edit/addendum: In skycrane's circumstance, I find it VERY strange that they didn't have a problem with the CP3 installed. That is in no way factory and the HPFP is part of the new warranty. I would think VW would have a real problem with that.....but maybe not

StayPuff - I also had a CP3 HPFP installed. I was initially concerned that any modifications would stop the fix from happening. Afer reading the booklet they sent out I was encouraged. It mentioned any HW or SW modifications affecting the emissions system would have to be brought back to original conditions before proceding with the fix. So I took it in and didn't tell and they didn't ask. The hardware side of the fix is finished - just waiting on the DSG re-flash which they are having issues with on the 09's. So I don't think the CP3 HPFP is an issue.

why would they have a problem with a part ( great improvement) that would save their butts maybe later That is if they even know how much better it is than their pump

That's great that you guys were able to get it done without having a problem with the CP3 installed. There's no doubt I wouldn't have been so fortunate. It will be interesting to see that those who have swapped out the pump, but have left everything else intact, will have problems with any warranty claims in the future....unless you're like me and couldn't care less. If I knew it wouldn't have prevented my claim, I would have done the CP3 a long time ago. Thankfully my original HPFP at 118K miles hasn't imploded. I'll be swapping it out soon enough though. I ordered 2 used pumps and a seal kit from England and will be rebuilding my own. The pumps are supposed to arrive today and the seal kit later this week.

thanks for all the great input guys...but might we get back to the original thread "post fix impressions"....as opposed to "will VW notice my tune/modif's if I take it in for the fix"?

I ask bc had an appointment for today, but after reading this/other threads about post-fix changes, am having second thoughts, postponed appointment, and am seeking input help on if it's safe to do the fix... is the fix "proven" or "tested" enough? will it cause me other CEL's...etc?

than ks in advance..

I would hold off given that you have an 09 with a DSG transmission. VW is having difficulty with the DSG re- flash for that model year and a number of us have our cars parked at the dealerships waiting for SW update. Everything else was completed - consequently, they won't release the cars in their current state. There is a thread on this. Look for the SW fix before rescheduling your appointment.
