Just checked the date on the Yuasa battery that was fitted and suspect I have the source of the problem. I can't see a manufacturing date, but the battery has stamped on it a "recharge due" date of September 2016. Considering that it was fitted as a 'new' battery in August 2018, that might well have something to do with the problem I had. Lesson learned - will be checking dates on batteries in future!

As I say above, there was no quibble from the supplying dealer, Hills of Lymington, on refunding me the price of a new Bosch battery.
Probably sulphated as I suspected on the shelf reducing its capacity to deliver current. Good on the shop, in refunding your money

Afternoon all,

Its my turn with this fault, hoping its only the battery obviously!

Whats the general consensus on the best battery available for a Granturismo S?

Cheers.

Its Exide 100amp....nuff said. Mines been brilliant. Personally I have heard of the Yusa going up the swanie so this or Bosch.

Battery change didn’t work ☹

Does anyone know if there Is a reset procedure at all before I book it in somewhere?

EDIT....

Scrub that (I should learn to read the thread properly....) took the car out and it cleared before the end of the drive. Praise the lord & back to the rugby ..

:p

If you’d taken that to Maserati your gearbox, clutch and actuator would be out on the workshop floor by now.

Ha ha probably....

I’ll save all that tension for when I take it to Maserati Colchester in July for a service.

Coming back to this thread with a few further thoughts almost a year into my ownership of the car. Bought a second new battery - the Exide one recommended above - which still didn't solve the problem.

I'm away in the week so generally leave the car connected to a CTEK charger (MXS5 or MXS10). I had even tried completely disconnecting the battery (both positive and negative terminals) during the week. Strangely that still didn't solve the problem completely (so it appeared it wasn't just a simple battery drain problem). Which is when I had a thought... I wondered whether there was something about the battery chemistry that meant it wasn't giving full output immediately after being disconnected from the charger. So I am now disconnecting the CTEK the night before taking the car out for the weekend, and it seems to have made some difference. Incidence of the errors on start-up is now much reduced.

The car has also been in for its four year service this week, and after I had a debate with the main dealer that installing the Maserati standard battery (for 'only' £489, fitted) was not an acceptable solution, they claim to have cleared the errors, updated software and not to have been able to reproduce the problem. I pick up the car on Friday and will see how we get on...

Mines into Maserati Colchester/Essex Tuesday (for a minor service, minor of course being £1,300 before they call and say I need XYZ)....

I'm not into this leaving car batteries on charge 24/7 I know the CTEKs are supposed to be the dogs but I just don't like the thought of my battery being almost or 100% full all the time..

I connect the CTEK for a couple of days or so every fortnight (I don't drive the Maserati that often).

Further update to this thread. Not solved the intermittent problem (which appears to be related to the rear near-side ABS sensor) though it does seem to be voltage related, but have now had a permanent failure of the front offside ABS sensor - so the car is in with Migliore this week for a replacement.

On the advice of Vic at Migliore, I am only replacing the front failed sensor, and will continue to live with the intermittent failures at least until the next service (this summer).

I had a new battery about 12 months ago that died recently. It was an exide premium one. Turns out it wasn’t the fault of the battery but the alternator that was slowly killing it. No alternator light on dash but was clearly not charging it correctly. I think it was actually overcharging it. Whatever it was the alternator was the issue so throwing batteries at it would just kill each battery in time.

From memory, the alternator should charge the battery no higher than 14.4V (please correct). There's actually two parts to the alternator. The generator bit (fairly reliable) that creates electricity as alternating current (not a dynamo) and a rectifier.

It's the rectifier's job to convert the AC to DC, these usually consist of a bridge rectifier (4 diodes in a certain configuration). Over time the silicon diodes break down causing voltage fluctuations.

My old SEAT Ibiza had this issue and a replacement diode pack sorted the issue, more cost-effectively than replacing the whole alternator.
Whether the Maserati rectifier pack can be replaced, I've not looked into but they are fairly standard parts. Probably off an iveco van.

Good call - all the QP and many GranTurismo are int he window where alternators might be failing. Well worth getting alternator checked at the same time as battery is replaced.

My own alternator was packed off for a refurb - thought better than cracking it open myself. Few skinned knuckles and many expletives involved in the task. Price of new one is proper Trident Tax.

It may not be the issue in this case as I was getting no warning lights at all, but yes, certainly worth checking.
