One comment I would make concerning the Banner article, when I input the details of my wife's VW Polo, it states the correct size for a "like for like" purchase, but that article also outlines which model is their "upgrading" model - at least for 6C VW Polo, the battery tray fitted to 1,2TSI 16V engined cars will not accept the slightly longer "upgrading" suggested model, to do that you need to remove the original battery tray and buy a bigger replacement, in this case the battery tray for the diesel engined 6C VW Polo. So always be aware of that maybe being an issue, and where it is an issue, make sure that the extra battery tray length is still okay for fitting into that car model, along with checking that the battery cabling will stretch that very short extra distance.

My 2013 fr184 had gradually started taking longer to start,turning over for 10 to 20 seconds before firing up.I'd also noticed sometimes the battery started struggling.Having read this thread I purchased a Yuasa 096 AGM YBX9096 to replace the Varta 7PO 915 105.Changing went well,although I did have to borrow an extended socket bar to remove the battery clamp.Everything was straightforward and when I started the car quite a few lights were in alarm but they cleared when I turned the steering wheel full left then right as previously advised on here.The tyre pressure indicator took slightly longer to clear.Since I've changed the battery,I've noticed the stop start has started working correctly.

Hi. that's all what you would hope it would be but you make no mention of what you're doing about "coding" the new battery to the car? If you fail to do this, although the systems are all working well at present what won't be optimal is the charging characteristics for the new battery. You may or may not know that, modern vehicles with stop/start technology monitor their battery performance very closely - look at the negative terminal on most modern cars and you'll see a wee black electronic "box". This is a battery condition monitor which is feeding info on battery performance to the ECU which controls stuff like charging and whether Stop/Start is enabled. What many don't realize is that it alters the charge characteristics as the battery ages and becomes more internally resistive. If this is not "reset" - ie if the relevant ECU isn't "told" that a new battery is fitted and the battery spec, then it'll continue to charge as it was with the old battery fitted. I've been told that if you don't reset then it can dramatically cut the longevity of the new battery.

Sorry if you already know all this, but you make no mention in your post and it's important others know about this. Of course you need a suitable scanner or whatever to do this - like the dealer tool or VCDS or other which can do it.

Thanks for the heads up,I'll have a look at getting it coded although I don't fancy asking the dealer as I know they'll want some ridiculous amount of money...I wonder if a local remapping company can do it..

Anyone with VCDS, OBDeleven, maybe even Carista can do the coding.
