This worked for me as well. Just make sure you speak to your SA and/or Workshop Manager before handing over your car. I got my 2nd service done, gave the car in the morning and drove out at around 4 in the afternoon, without any issues.

Additionally, as per this article Volkswagen to recall 3.24 lakh cars in India over emissions scandal, this update is voluntary.

Thanks a lot guys. I will talk to the SA and the service manager and ask them not to do the update. Fingers crossed!

How can I check if my car has the OPS module or not?

I plan to upgrade my RCD 320 to the RCD 330 Plus, and wanted to know if it will automatically display the graphical lines, upon engaging reverse or do I need to install any additional component or modules.

My car has factory fit parking sensors (4 each front & back), along with a button to manually switch the system on/off.

Yes, the update is "VOLUNTARY". But, for some reason in future if service guys have to plug in their diagnostic tool..what about the update?? I am not sure how it is being calibrated. At times, the device would auto update before running the scan. Please get it confirmed.

Hi tanveer, Thanks for giving me that push to come down to mumbai.
need your opinion on below thing, did you also observe similar behavior?

That thing called shudder:
I mentioned this in my first review post remap, in 5th and 6th gear. Today i wanted to see exactly what happens here. So i check the speed, 100 kmph, 6th gear, rpm around 1500 and then i floored the pedal. The car shudders exactly between 1700-1800 rpm and then flies. What i can make out is that the torque delivery is the reason. Entire 380 or 400 NM torque is released at 1750 rpm, which the gearbox or wheels can not handle and takes its own time till 1800 rpm and then starts flying.

Can someone come out with a right reasons for the same? Is this behavior expected or should the president be worried?

Welcome to Mr. ESP kicking in! The shudder is a compensatory mechanism that I experienced in the Skoda Superb 1.8 TSI when I was test driving it.

I will ask my acquainted SA whenever I will visit the workshop however the next service (3rd, 45k) is not before 70 days.

Can't be ESP, definitely not in 5th gear! Even in the Superb I'm sure you must have experienced it in 1st or 2nd gear?

Really?? But i dont see ESC light flickering at 100 kmph at all. If it kicks in, the car should also signal the driver in some way, isn't it?

It could be individual wheel braking.. The light always doesn't flash when the esp kicks in. It's a nanny system. Happens in my Polo, especially after the remap.

Not in 6th gear at 1500rpm, trust me. There is no way at that rpm and at that speed that any wheel will lose traction so that ESP has to kick in.

The shudder which Mission_PGPX is getting is because he is lugging the engine, and once there is enough torque the shudder disappears. Its completely normal, though I would suggest downshifting instead of applying full throttle at such a low rpm in a high gear.

So Basically, i dont need to worry about this behavior. Petes said it will take about 1000 kms for the ECU to re-calibrate based on my driving style. I can expect such behavior until then. They say, its a self learning ECU. damn, these germans . The machines learn by themselves and we have to go to schools.

I may be totally wrong. You need to explain your shudder better.

I second that. I used to experience the shudder in my 1st gen Dzire MJD (known for the infamous turbo lag & then the famous turbo kick) whenever I floored the pedal around 1500 rpm in 5th gear.

Thanks Akshay, your justification seems more logical to me. I never apply full throttle to take off from such speeds, its the testing of this remap in various conditions made me do that to my engine. My bad.

However, for those in favour of remap, the engine does pickup linearly from here if pedal pressed gently without any such shudder. There is still enough torque available to run but not to fly.
