I have a 2015 Superb Estate 2.0 TDI CR 170 ps Elegance DSG Mark II (Euro 5). I am amazed that the original Varta AGM is still working since I bought it from new 7 years ago.  However, I guess the voltage has dropped hence the stop/start has stopped working at traffic lights; not a bad thing really.  I am thinking of changing the battery myself. My questions are:

 

1. Do I need to get another AGM spec battery even I don't really need the stop/start feature?
2. Do I need to have a battery tender to keep the vital electronic alive (i.e. keep the 12v current) while I am changing the battery? Have it got any sort of security code? (I did ask a local Skoda but no joy. They just refused giving me any sensible answer. They just said: "bring the car in" - so they can charge me.

 

I would be grateful if someone has done the battery change on the Superb before can share the experience and knowledge.

 

I will definitely get another Superb - a solid trusted workhorse taking me to Spain and back many times!

 

I would recommend sticking with the AGM, and make sure the Ah rating and CCA are same or better.

 

Sadly you will need to code the battery so that the car knows how to charge it.

If you fit a non-AGM/EFB battery you should disconnect the battery monitor signal connector from the battery negative post. The alternator should then revert to a fixed voltage output that should be OK for a conventional 'wet' battery.

No

Many Thanks for the replies. I guess we need a programmer unit like Autel to tell the car what battery is being used if we want the Stop/Start. I wonder if anyone knows of a cheap programmer that can handle this? Say if we just put a AGM battery and connect the sensor, I know it will come up with some errors but will it stop the car running at all? I never see the point of Stop/Start; can't be that good for the engine.

 

Do you have someone near with VCDS or VCP / other that could code the battery in.

 

Some still think Stop/Start will break thing's, many things got beefed up to handle this, starter for example, of course things will break, but my 7 year old car is still on original battery.

See this post, make your own mind up based on what's written in the banner link: https://www.briskoda.net/forums/topic/499676-battery-causing-various-errors/?do=findComment&comment=5607340

 

Thank again to all the contributors to this thread. The AGM battery on my Skoda Superb (2015) was successfully replaced with the help of a diagnostics unit Antel AP200. Perhaps I will share my experience here to help others who may want to change their AGM battery on their Skoda with the Stop/Start feature.

 

My original Varta battery from 2015 was working perfectly fine with the exception that Stop/Start feature stopped working (I see that as a blessing). Guess the voltage of the battery had dropped due to old age. I had to drive to Spain (2,400 miles round trip) so I just went to my local GSF Car Parts and they sold me a standard Drivetech 76 Ah battery when I gave them the car registration. At the time, I had absolutely no idea about AGM battery technology. Luckily I didn't change the battery but just put the new battery in the boot as standby. The 7 years old battery performed normally in my long trip albeit no "Stop/Start". On my return, I did a bit more research on Briskoda and Youtube and discovered that I did need a AGM battery and a diagnostics unit.

 

Antel AP200 is just a little bluetooth dongle which talks to an Antel app on your smart phone. Great value for money for just £68 via Amazon.

 

Here is how I changed the battery:

 

Negative terminal detached followed by the positive terminal (10mm nut). Removed the 13mm securing nut on the side. No need for any tender to keep the cirucuitry alive. No radio code as in the old days. Took the lower half of the plastic outer case wall off and it made refitting the new battery with the original inner sleeve so much easier. The outer case wall is only secured by some sort of "push and click" type joints. No screws or nuts involved.

 

Having the new battery fitted and secured, the next step is to use the Antel AP200 to tell the car control unit a new Varta AGM bettery has been put in and what capacity it has via the "BMS- Battery Management System" tab. Note that if your car takes AGM, don't replace it with a EFB although both are "Stop/Start" type batteries. GSF did give me a EFB battery when I returned the standard battery.

 

I was warned by the Youtubers that the car would show quite a lot of "false positive" errors after a new battery is put in. In my case, I had two errors - steering assistance and brakes. The AP200 managed to reset them. Now the car is good to go with a well deserved new battery. The driver himself has new knowledge and a new tool to monitor the car and to do things like resetting the service warnings after changing oil by himself.

 

The only regret I have is the "Stop/Start" function is working again. I have to press that cancel button everytime I drive the car!
