Hearing from Johnny experience if any of you need replace your battery I fitted the above from Tayna was about £130 inc postage. Works perfectly and came with a 4 year warranty. Was the cheapest one they do but enabled stop start to work again! Did look into other brands Halfords / Enduroline but this was considerably cheaper.

I got a new battery fitted last Sunday from the AA as the car wouldn’t start after me washing it. It was a Bosch and cost £285 (ouch). My stop start has started working too. It hasn’t worked for a long time. My air bag light was on too but has now gone off after a couple of journeys so hopefully will stay out from now on.
