Remap is imminent to get the car back to its character.

What car is yours? I drive a Vento TDI 2012 model and I am not seeing any increase in noise after the update. Anyway 1.6 TDI is already a noisier engine. I did see that the power delivery is bit linear than before. But still not so much that it feels slower or drought of power.

Mine is a Vento HL 2011 done about 113000kms.
I was looking to take it to a FNG to get the car checked thoroughly once.

wondering if there is a way to Undo what is done, without voiding the warranty ?

Has anyone done it ?

Thanks

Technically, it should be possible to get the software to the original factory version and then update (if applicable) up to the diesel gate level. After all, it is just certain codes and configurations that are setup.

The question in point is, would VW want to do that! Currently the answer is NO. However, considering the diesel gate issue has no relevance to Indian emission standards, we should be collectively able to impress upon VW.

From what I have read on this site, they say it cannot be undone. There is a very good chance that this means that they will not undo it.

Some members have mentioned getting their vehicles tuned after the fix to restore (and even enhance?) the performance. I confess, I have not searched: I wonder if there is a thread devoted to post-fix VW tuning?

A remap can be done to fix. I think, I read somewhere in this thread only where somebody has rolled back to the original software. Also, many threads exist where remaps, performance tuning and mods have been done.

I got a call last Friday from Vinayak Skoda asking me to get my Rapid 2012 1.6 TDI for the dieselgate software update. I said I was not interested. They said ok and hung up.

I didn't know it was going to be so easy. Will have to watch out during next service though. I plan to explore Bosch's Coco service center for my next service, since it is already five years since purchase. That should keep me insulated from Skoda's software update. Lets see.

I had my Jetta updated during its service at the end of March. Having driven it around town and a trip to Hyderabad comments are as follows

1: Idle speed 900RPM - makes clutch a bit heavier
2: Initial pickup - slightly less
3: Mid Range - not too much change, a little less blunt
4: High Speed Cruising - No change
5: Fuel consumption - 5-10% worse

Car has 53000km on the clock. I used Shell V-Power on the trip to Hyderabad and normal diesel on the way back - not too much difference.

I might look at a remap for a little more zing

Majority of the votes are for option 3. People who decided to stay away from the upgrade. My car (Skoda Rapid 1.6) is due for the upgrade this Friday. I will ignore the opinions of those who voted for option 3. Looking at the opinions of those who have done the update, I can see there are more unhappy owners than happy ones. Now I'm in a dilemma what to do. Is there any way of reverting to the original software if I'm not happy with the update?

I doubt this would be possible.

What makes it worse is that I doubt Skoda will give a warranty and free of cost repair for any part that may go wrong after the update - especially given so many people are facing small issues with the car.

As T-BHP is just-about my only source of such news, it must have been here that I read that VW claim this update cannot be reversed. I'm sure that what can be done can be undone (software tuning changes can't be undone?) but while VW maintain this flat denial it is effectively impossible to do. Unless/until someone discovers how to hack it.

If VW were not so hard-line with this write-only stance they might find more customers willing to try it.

At the time of posting the opinions are as follows:
- 60% have not done it but have decided not to do it based on other peoples experience.
- 12.17% are happy.
- 27.83% are unhappy.

I will stick with my decision to ignore the opinion of those who have not done it (thought I'll probably join them). Looking at the 40% who have done the update, the unhappy ones are more than double.
I was to do the update on Friday but the machine at the dealership broke down so I've rescheduled for 25th. I will go there and talk to the dealer and tell them I don't want the update. My reasons for the same are as follows:
- As stated earlier, the number of unhappy people are more than double the happy ones.
- I don't want to loose out on driving pleasure (even though I hardly use the car).
- The update is not reversible (at least officially).
- Dieselgate was cheating the American regulations. The cars still comply with the Indian regulations at the time when my car was purchased without the update.
- I maintain all my cars and will maintain this one too as long as I own it to ensure it complies with all environmental and safety regulations applicable to the vehicle.

One of the reasons why I want to skip the update.

My car will soon be out of warranty anyway.

I guess the only way to do it is to do a remap. Most reamappers maintain a copy of the original map so it won't be difficult to find one. But if I'm going to pay someone for that I might as well go in for a proper re-map.

From all the above it looks like the fix can be reverted. I checked with the VW service personnel known to me to understand what comprises the fix. It is a two step process in simple terms

• adding a additional filter element
• software remap

These two go hand in hand and hence if you have to revert it, the filter element also had to be removed as the software remap may screw up the whole thing with an additional filter in place. I hope this answers all the questions above.

OK, to bust the whole thing a group of 8 of us set out for a 1000+ kms trip consisting of highway, city, narrow roads and hill/ghat road in my Vento and a friends Rapid. Both are high end 1.6 TDI, bought in 2013 and 2014 respectively.

The following were the inferences.

• Engine noise is a bit increased than before
• Acceleration is a bit linear though not annoying
• Mileage was around 19+ kmpl - would have been better if we maintained cruising speeds.
• Some of the drivers in the group felt Rapid took a bit longer to accelerate from rest than before
• Vento's acceleration from rest also had a negative impact but not as much compared to the Rapid - as the owner of the vehicle, driving it for the last 4 years, I can clearly say its not that significant to bother

To summarize, I feel as it is good for the environment lets do it. To me, I didn't feel much of a difference and I am no laid-back/sedentary driver. You may need to change your driving style - if you have been driving your Vento/Rapid like a Swift then try to switch to Punto mode, which has a much linear acceleration than the former. That will bring back your smile.

Hi friend. I saw your earlier post (before editing by bblost) on the speeds at which you went. I am relieved that you and your friends are in one piece and nothing untoward happened when you went at such high speeds.

I would like to request all BHPians to please remember that there is someone waiting at home whenever you take the wheels. Please drive responsibly and safely, not only for your sake but also for your near and dear ones.

bblost, thanks for editing the message. Appreciate.

Agreed. It is certainly not safe to drive more than say 120 kmph in our roads. Just to note that the speed mentioned is not the one sustained for a longer duration. It is the peak speed for testing purposes. I used to touch high speeds normally, though mostly I may be running between 80 to 120 kmph. However, after the trip, based on the advice by friends, we made a resolution that we will not go more than peak speeds.

Not to deviate from the topic, have you shared your experience after the fix?
