However ASC check up gave green light to the battery and said all cells are good.
However, today in the evening when I started the car post a 8-10 hr gap, the entire dash MID lit up with ABS / EBD / Park Assist / Maneuver Braking/ Cornering lights et al not functioning. And the ABS not functioning light stayed on. This symptom typical of ABS sensor gone kaput in a VW vehicle. Its a Diwali at the dashboard.

Car went to workshop and problem got diagnosed. Quote:

You were correct. Quote:

And you were correct. I'm running VARTA batteries, same spec as what came as OEM. With these electronics over laden cars, its sensible to stick to the OEM recommendation.
Car went to workshop. Turns out 1 ABS sensor had gone kaput and that was replaced. However the battery also had generated an error code in the ECU. So the VARTA battery which was 16 months old, was replaced under warranty. No questions.
In addition, the dual tone horn was behaving wonky for bit. Actually it had first behaved wonky in Monsoon 2022. However, after the rains, it became normal. I dragged the horn till October 2024 when finally it was going kaput consistently. Mind you, still not totally dead!
I had asked ASC to change the horn. The set costs about 7k( low tone + high tone). I was surprised when the bill. ASC changed only the half of horn that had failed rather than changing the both units.
I have just ordered for the rear shocks and they will be changed shortly.
The car is back and sprightly. It currently stands at 952XX Kms. Quote:

Not sure why do you say that. Water pump, Flywheel are known issues. German cars, their roof liners start coming off in about 5-6 years. That is a known issue too. Rest are just regular wear and tear for a 95K Kms run car. Only extra ordinary item was the steering rack.
Also may be I baby the car a bit. I explored the upgrade path - https://www.team-bhp.com/forum/luxur...ml#post5861467 (Volkswagen Passat: What are the possible upgrade paths?) But looks like there is nothing I will get as a proper upgrade unless the new Superb gets launched (in CKD/SKD avatar and not CBU). So keeping it in ship-shape condition will ensure that its a reliable daily driver to 150K Kms atleast.
