Am I ok to do a direct swap of the battery myself? Or does it then need to be coded to the car etc? I suppose I'd probably need the error codes read and cleared regardless?

Yes, it’s not that clever, in my experience with these faults they clear (or go into memory) before the next start. The clamps are a bit of a faff, but it’s doable with a small socket set.

Ok. First port of call is a battery change then. Still keen to get any further thoughts anyone else might think are pertinent. Again, your help is much appreciated Zep, Conaero and Phil.

If you have a multimeter see what voltage is in the battery.
First with ignition off should be over 12 volts.
Ignition on see what it drops to and then with someone cranking the starter.
If it drops below 10 volts that will cause tom foolery.
Modern cars and control units for every function are very voltage sensitive.

I think my battery is a Yuasa. Conaero, do you suggest changing the battery as first port of call?

Zep, I agree that things aren't made the way they used to be! haha

I do with anything but a Yuasa, we see multiple failures.

Current top 3 we fit in this order - stock dependant:
  1. Varta
  2. Bosch
  3. Exide

Interesting, I think I'll steer clear on my replacement then. With respect to the correct alternatives, I saw this link to an Exide, https://www.tayna.co.uk/car-batteries/exide/ea1000/ can you advise as to which Varta is the correct one? I'll then take a look and get something ordered.

Just ordered the Exide on the basis of recommendations here. EXIDE call their 019 an 017TE for some strange reason (direct confirmation from the retailer). It's got to be better than the Maserati recommended one which has died after 2 yrs despite being on a CTek regularly.

I think I'll do the same and go with that battery too, it seems well regarded and can't be worse than the Yuasa by the sound of it!

Common reason we see for premature battery failure is constant Ctek trickle charge connection.

The battery thus seems reliant on a constant 12v supply and losses it’s ability to function correctly.

My advise is to yes use a trickle charger but sparingly. Flick it on the day before you need it if laid up for more than 1 week during winter or 10-14 days during warmer times.

Absolutely, the “intelligent” chargers can end up giving the wrong float voltage, this changes with temperature and should be reduced when it’s hot, or it cooks the battery. It’s a balance, if the battery goes below about 40% charge it will get really upset. I have used a timer previously, just running the charger for a couple of hours a day.

Now, this is really useful info. And perhaps my Ctek has been guilty of something like that, as I've definitely left it on trickle charge for longer periods on occasion.

It’s your battery. I take it you get the Park Off error too?

Winter + little use = voltage drop and systems don’t have enough power to complete properly.

Tanya batteries, Exide Premium 100amp = £89.

Having simlar issues with mine, check transmission, Park off, MSP etc - battery reset works for 100 or so miles then occurs again. Dealer said they changed the battery but it is onl 88Ah and 680A wondering if it is up to the job? Going to try MAF clean also

Does a battery go flat over time even on the bench off the car, nothing connected?

Yes, batteries self discharge due to the internal resistance. If you are storing a battery, charge it periodically as if the charge drops too low, it will damage it.

So how does a battery get charged in the first place?

But a battery is goosed if it drops below certain voltage? But it's ok if it has never had any charge in the first place?

They are charged as part of the manufacturing process and then sit on a shelf. The length of time between the manufacture of a battery and it being put into us is one factor in their life span. Always get the newest one you can.
