I parked in the drive at about 6.30 PM Saturday and went out to the car at about 1.30 PM Sunday. The remote unlocking didn't work and when I approached the car it was unlocked. It was completely dead electrically. I put jump leads on and started it and then drove 50 miles or to charge the battery. I checked that no lights are staying on - apparently not.

The car is used regularly, virtually every day, the usage was similar in the winter and I had no such problems even with the heavy electrical use characteristic of winter urban crawl.

It was parked at 5.00pm Sunday and was fine at 9.00 am this morning - anyone with any ideas?

Stereo? Car cam? Anything plugged Into 12v socket? Obd tool left plugged in?

Huwcymru,

Have a read of my thread "Flat battery or not" dated 24th April. Sorry that I cannot direct it for you as I do not know how from my ipad.

Where in Cardiff are you as I work in Cardiff every day and live near Magor. Pm me if you wish and we perhaps could talk.

Maybe another case of crap VAG battery - posts about battery failures on here regularly including g mine which was replaced at Christmas

I wondered about a crap battery, time will tell.

Friend of mine had the same problem recurring over a number of weeks. If the car was left for a few days the battery would be flat.

Skoda eventually diagnosed loss of battery power via the heated seats.

It does sound like something continued to draw a load after you locked the car, rather than a dodgy battery. I don't suppose anything was left plugged into the 12v sockets, or have you had anything retro-installed that may have been piggy-backed off one of the 12v socket fuses?

Nothing plugged in, in fact I usually leave a usb charger plugged in but removed it. No mods to the electrics either. If I had left the radio on ( unlikely) it switches off after an hour. Crar will be left at an airport later this week so a good test!

I had my ipod plugged in but removing that made no difference and the ipod would never draw 2-3A anyway, if it had done then "Ithink it might have become a bit warmer"!  .

Stick one of these on the dash whilst it's parked up: http://www.solartechnology.co.uk/nqp-or-used?product_id=309

It the battery has been discharged to the point it wouldn't power anything electrical on the car then there is a good chance the battery has been damaged now anyway.

 

Time will tell but at least it is under warranty.

 

Take the number for Skoda Assist with you to the airport would be my advice!

There should be a small card with your booklets well I had one that has those numbers on it. Mine is permanently in the sun visor.

What year is your vehicle. My 2014 Superb Estate 2.0L 170 PS with Start/stop and energy recuperation only has a 68 Ah Varta Battery, I queried this with Skoda UK who claim that after checking with the factory it is the correct battery. I then contacted Varta direct who informed me that it is not the correct battery. Skoda UK are perfectly happy with the battery fitted and only say if it fails you have warranty.  Even though they claim it is the correct battery, if it fails I would expect them to say you have the wrong battery and try and get out of replacing. To date I have had no problems despite having to leave car in my garage for several weeks due to hosptalisation.

When they replaced my battery (pre-FL no stop/start) they gave me a 72Ah battery compared to the original which was low/mid 60s Ah

I've had my Superb II for three years and the battery has been a problem for the last 18 months. Skoda replaced the first one after keeping it for a week and declaring it 'faulty'. I took the car to the car wash yesterday and it refused to start as the car wash men went to move it. Having left the doors open and moved the power-driven seat was apparently enough to flatten the battery. My son-in-law (engineer/VW mechanic etc) reckons that the car needs to be driven for at least 20 minutes after start up in order to recover the power loss suffered during the start up process. The cars are designed for motorway use, not local trips, and rely on being driven a good distance in order for the battery to maintain its charge. This creates a bit of a dilemma because I do fewer long journeys now so I'm stuck with a car that will need a trickle charger feeding it in order to get it going when I want it to! In every other respect it's a very nice car but this is a bad design fault, it seems.

See my earlier post. After weeks of checking Skoda diagnosed my mates car to h ave power loss through electric seats.

Now remedied and no problems ever since.

Good lick

Thanks. I missed that earlier. I'll have a word with the garage.
