There "might" be a reset, according to my service writer. He's not sure if it works with the 958s, like you said. I don't remember the exact procedure because it didn't seem to do anything, but it included turning the key to the on/ACC position, not just stiking it in the slot.

I think the "contact" in the original post over there is to put key in and turn one click (on/ACC position), but don't start. That'll energize the computer (contact = connect the contacts?) and let it recalibrate and store things. Same thing when you "cut the contact".

"Put back the contacts (without starting) during 5 minutes"... could that be turn the key back on FOR five minutes (without starting), rather than within?

That makes more sense to me, anyway. I don't remember a 5 minute recalibration/reset period, though.

Similar to the above post, here is the Mercedes ECU procedure I used to use.

1. Turn the ignition key to the on (not start) position.

2. Press the gas pedal to the floor and hold for five seconds.

3. With gas pedal depressed, turn the key to the "off" position (don't remove the key), then release the gas pedal.

4. Wait at least two minutes for ECU to reset.

​​​​​This reset the adaptive driving settings from learned gas saving granny mode to factory settings with more aggressive performance. It’s been around for years and won’t hurt anything to try it.

According to the thread below, Eskimo1 indicates the TCU in the diesel is now hard coded post fix

Fix was done today . pick up tomorrow, we will see how it is. I forgot they give you a full tank of diesel, and we brought it in full

@MJG911

i have not done the fix yet to my 2015. Will be interested to hear your experience. sc

dollarlongnecks

I did the exact same thing... I've heard some dealerships make that up for customers at a later date, but my crappy (ex) dealership didn't.

So far, my wife has about 3 hours post fix and says it feels the same or even stronger. But the stronger reference is probably because of the 4 cyl. Macan loaner she had. I did a quick drive and it feels the same to me. But, we have always had some hesitation and sluggishness in this one as compared to our previous 2013 model, so who knows?

Well, it is almost the end of the saga. As the attached file dated June of this year shows, VW reached the 85% participation rate awhile ago (pag 38). Looks like there are around 4,000 CDs that are "unfixed." Those are rare indeed

[edit: As a side note, looks like California is where most of the CDs reside, and the total production of Gen 2, is not even a week's worth of a Ford F150 truck?]

[edit edit: I misread the pdf. It is not 4,000 CDs but 3.0 tdis, including VW and Audi suv/cars]

Wow good update. I was hoping for a glimmer of light that 85% wouldn’t be reached. Since it has been reached, I guess it’s time for me to get the fix before the deadline. I’m hoping for the best and for no lag issues.

Same here, we plan to have my wife's 14 fixed in January.

I have also been a holdout, but finally gave in and took my CD to get the fix and the DEF heater recall done on December 20th. They have had the car for over a week now and although there have been two weekends and Christmas in that time period, it does sound like a long time. Has anyone else had either of these recalls take This long? They told me last week they were still waiting for one more part (I assume that is for the heater since I thought the emissions fix for a 2015 is only programming.

Mine stayed at the dealer for a week, and it was during non-holiday time. I did not mind bc I knew they were trying to be as detailed as possible. But then, mine is a 2.1 that required hardware changes. Memory not working well, but is 2015 the first year of the 958.2? So, yes, for a 2.2, it seems a long time. Most likely backordered DEF heater.

Believe the CD fix is a part number as a kit for the 958.1. Exact parts are not itemized. There is also a campaign for an updated NOx sensor after the fix because the fix will kill original NOx sensors.

Kayze

Yes, it is the first year of the 958.2, so no hardware changes. My service tech said he needed it for a few days b/c the programming took a few hours and if there is any type of power blip they need to start over. With that said it makes sense they don’t have many DEF heaters laying around in Florida, and that or the NOx sensors that I was unaware of are probably the parts they are waiting for. I appreciate the replays.

Hey guys.

T-regs owners are getting letters from VW for a new recall related to the dieselgate. It looks like the fix is addressing an engine shudder on a warm up. Some folks here and I experienced that as well. Anyone heard of Porsche fixing the same issue on CDs?
