The car is overall driving great, and is super fun to drive because of the punchy mid-range. With the Polo range discontinued, the exclusivity of owning a Polo GT is just going to increase!

When the engine is shut off, the key comes out in any gear. (It should come out only in 'P'). Link to similar issue - link.

It's been there ever since I remember, but there's a strong vibration when the engine RPMs are in between 3000-3500. The vibration dies down after that. There are more posts on similar vibrations, but haven't found anything conclusive yet. Engine mount was a suspicion, and I got it replaced during the service. The older one had worn out, but didn't warrant a replacement as per the technician. This didn't reduce the vibrations.

I got the car serviced (60k kms service). I insisted on changing the mechatronics oil, but they were in denial that this is every carried out as a routine maintenance. They went as far as saying that they've never performed this on any car to date!!

The engine oil, spark plugs, V Belt were changed, everything topped up. I had asked them to check the battery, because the car would take longer than usual to start. The report came out okay.

Fast forward a few days, after the car starts up, the gear selector indicator on the MID would start blinking, and would stay that way till the brake lever is depressed. I read a few posts, asked fellow owners across different forums, and some of them did mention replacing the battery resolved this issue.

I went to the SVC. The SA insisted on first trying to assist the battery with a jumper pack to see if that alleviates the flashing gear indicator. Surprisingly, even with the additional battery pack in parallel, the gear indicator was flashing.

Did a bit of troubleshooting the good old way. Plugged in a multimeter, and checked the voltage during the crank. When off, the voltage was ~12.4V. While cranking, the voltage went down to 8-9V. Went ahead, replaced the battery, and voila! No more flashing gear indicators anymore!

The replacement battery is an OEM Made in Spain Exide:

I'm super relieved that it wasn't anything major, specially now that I have a remapped TCU, and ECU.

That brings me to the next point:

Also, has anyone else faced the vibrations between 3k-3.5k rpm? Any resolution?

I noticed that this is there on a lot of cars, but in varying degrees. Mine being on the higher side.
