Hi all, request your feedback/suggestions on the below issue I have been facing on my car after completing 1st month. Once it occurs persists all day unless I am going to the Service Center. Strange Coincidence? I have only used XP95 petrol till now, that too mostly from COCO Indian oil pump.

I bought home Taigun Highline AT on 25th Nov'22 and the first 30 days everything went well. After driving diesel engines for more than 10 year my 1.0 petrol experience has been a mixed bag. There were some wow moments with acceleration on high speed and some not so wow moments in lower rpm.

One fine Sunday morning(Dec 25), as soon as I started the car, the whole car started shaking just then I noticed the EPC light was on a bit longer than usual. Both went away when I put the car in D mode, followed by "Error: Start/Stop" on the instrument cluster. Visited Service Center on 26th Dec, "Error: Start/Stop" popped up on screen with extra vibration/shaking when I started the car in the morning however by the time, I reached the Service Center the error was gone. The car was scanned, Software updated, Electrical systems and car's earthing were checked - no issued found. Came back with the car, everything seemed ok.

Took the car out of 28th Dec, no errors popped up. Happily drove the car thinking something worked and issue has been resolved but I was sadly mistaken. At one of the longer the red light I realized that my start/stop function did not activate so I decided to fiddle with the activation/deactivation button and there it was again "Error : Start/Stop". Back to service center on 29th Dec. No issues this morning, car started normally. This time they kept the car for 2 days. System scan, spark plugs were cleaned, they test drove the car 40-50 kms. They did not face any issue.

1st Jan'23 - Caught a break on the first day of the year. No issues, drove the car for 50 kms (up n down).

3rd Jan'23 - Vibration and Error Start/Stop is back.

On one of my visits to Service Center, I was told to turn on the ignition then wait a few seconds before starting the car. If I am patient and follow these steps the error/issue doesn't seem to come up.

1. Are the VW/Skoda 2.0 car so sensitive?
This has never been an issue with my 6yr old VW Ameo or any other car in the past. Even with Taigun, first 30 days starting the car in one go was fine.

2. Should I learn to follow this rule and see how things pan out?

3. Or, is there a genuine issue with the car which I need to get it resolved?

Much appreciate any help you can provide. Last few days have been very stressful, its not fun seeing such errors/issues on a new car .

I haven't received an error message but sometimes it shows that the Start-Stop is not available i.e. the engine does not cut off when I put the car in Neutral.

Sometimes, the engine does cut off. But when I press the clutch after it cuts off, I get a message saying "Please start car manually" and the engine does not start on its own.

I have experienced this issue in my Skoda Kushaq 1.5 as well. At times, a message start/stop error pops up on MID, very rarely, and after turning off the vehicle for 5-7 minutes, upon restarting the engine I have never received the error again.
Skoda ASS was not able to diagnose any fault with the car.
IMO it is not related to the fuel, I have faced this error on XP95 and on XP100 as well.

Kindly keep this post updated in case you are able to find a solution for this.

Happy Motoring!

This is not any fault. Auto Start/stop is not meant to be available all the time especially when the engine is too cold or too hot it automatically deactivates this system to prevent engine shutdown.

You may read this thread below to get more clarity on this issue:

If the problem of "Error Start/Stop" continues, it should be examined to determine the root cause. The message "idle Start/Stop unavailable" is a typical indication that the feature is disabled when any of the defined criteria are not met like after a cold start or when defrost is on etc.

Thanks! Issues still crops up from time to time, in one way or another. I have dropped off my car at service centre again today for resolution. Let's see what they come up with. My SA has assured that they have raised a technical and will replace which ever part necessary to fix the issue.

If I was the Techie working on this the first thing I would check very closely would be? Guesses? BATTERY VOLTAGE!!

Right. I would check it before the engine starts in the morning and monitor how the voltage level plays out for about 15-20 minutes when starting up totally cold engone in the morning. The teachnician can even do this by hooking up a scanner and watching the live data. Point to remember. These technical glithces playing hide and seek happens MAINLY due to voltage irregularities. When the base voltage is not right in the first place, the various sensors and components lose their "bearings" because the main thing they need to work properly is the right voltage. Pretty simple. The voltage level is the "0" in their maths without which they cant do much. We Indians invented the 0, remember?

Even the big Mercs etc lose their bearings and have Auto Start/Stop issues mainly because of battery voltage related problem. Its another story that they have 2-3 different batteries(read S-Class and above) mainly one main battery and 1 or 2 auxiliary batteries depending on model. Mainly the auxillary battery acting up causes Start/Stop issues in these babies.

So I would start there. Its very easy to miss this one vital step for most folks. I only hope the ASS people are not playing stupid and then plan to plonk a big expense on you later. I've seen Skoda people racking up bills in Lacs just because the car was sitting for couple months and the battery was weak.

Could help to know if other folks with this drivetrain are experiencing similar issues.

Status update:

Got my car back this week. As usual they didn't find any issues with it. Battery voltage was also found to be ok.
Some spring cleaning was done on my car by service centre as per the step by step instructions received from the VW technical team. Good news is that, in 100+ kms I have driven "error: start/stop" has not popped up again. This is when I give a fews seconds gap between switching on the engine and giving self.

Vibration is another story, I can feel the excess vibration in my seat and arm rest for about 20-25 seconds when I start the car in the morning. Does anyone else have the same issue? SA said it happens if the AC is on during the start but that's not the case. I get it even when the AC is off.
