@nta16 - thanks for the info - I put the battery on "Pulse repair" charge mode yesterday, (it took longer to charge than the normal mode) Unfortunately when inspected today it was down to 60% charge so it seems like a genuine problem with the battery. I will charge it once again on Pulse repair mode just in case I get different results. I doubt if the warranty period extends to 5 years but will have a talk with the garage that installed it on the off chance they might give me a discount on a new one

I'd be interested in this too, thanks!

Started having problems with my battery over the past 6 months, car struggling/failing to start. The battery is now five years old (see the images for the brand and details) (I'm not using the car much these days due to shoulder surgery) As can be seen from my charger, the battery charge drops a lot over an 18 hour period I charged it to full yesterday at 6pm (it was at 20% full before the charge), and checked the following day at midday and it was down to approx 40% That said, I went on hols for 10 days in July and the car started first time When I came back which was surprising Subsequent starts would require a jump start (from a NOCO Boost unit) but occasionally it'd start without a boost. With the engine started, battery voltage gets to 14v (which I think is indicative of the alternator functioning ok?) When the battery is charged to full the stop start system seems to work okay. My question is whether there could be some current drain which is pulling the battery voltage down overnight? (For example alarm/immobiliser etc) If so, what would be the best way to measure this? I have a multimeter but not too sure if that's the appropriate tool for this purpose. My next experiment will be to detach the battery from the car, charge it to full, and then check the charge 24 hours later to see if it has dropped. Any advice appreciated - thanks! Measured at 1pm the following day (40% full)

Thanks @weylandall installed and working now, The cable routing process was surprisingly easy.

Hi @weyland / all, Just getting around to doing the install now but having an issue trying to extract the unit - did yours pull all the way out? I can only get mine this far, as the cables are preventing it from pulling out further, have tried to pull out the connector out from underneath/behind the head unit but it's proving difficult. Also tried pulling the cables to get some more slack but very little give in them to pull out any further Any tips appreciated - thanks! C:\Users\ferga\Downloads\stereo2.png

thanks @PetrolDave, I'll drop it in to the mechanic and advise of the suspicion of the ABS wheel sensor

thanks @spindlegridley, interesting to find out if any others have seen the same issue and if/how they were able to resolve it

Ok, I'll try get it booked in for a code scan

When this occurred several times before, during a drive all the warning lights would turn off and adaptive cruise control, Park Pilot would all function normally again. However I have observed that within the same journey, all the warning lights could turn on again - it was very intermittent, now it seems permanent. Originally, the warning lights seemed to coincide with when I washed the car - as if moisture was causing the issue, though it would also happen on dry days. We had a very wet March here in Ireland and that was when the issue started again, though this may be just coincidental

It measures at 11.95v and 14.53v so battery looks ok

Thanks lads. I'll check the voltage today, what voltage should I be expecting started and unstarted?

Battery seems fine. Never struggles to start bought a new one approximately one and a half years ago

Hi Per this video, I am getting a lot of error codes on start up (sorry but I couldn't change the orientation): This series of codes appeared several times before but only lasted for a few days and then went away, this time they appears every time I start the car for the past 4 or 5 weeks. Since they previously appeared then disappeared, I assumed they were not validly showing any physical problem with my car. Has anyone seen such instance of all these error appearing? and if so, what did you need to do to resolve it? Thanks a lot Fergal

Thanks all! 👍

hmmm - from a close-up photo I'm now thinking maybe they are ultrasonic sensors for the alarm? thanks @langers2k!
