Important Safety Recall- Dealers not Informed

[tophamn]

Is this really the fabled over the air battery monitoring ? Cant remeber the number

Seems likely to be WRW1 that we've had recently (OTA) in UK.

So not WRS0............ (I remembered....!)

I had my 2 year service done today and WRS0 was applied also.

WRS0 - "Check on HVB cell modules and reprogramming of BMCe software"

£671.02 (no brake fluid asper brake hose campaign).

New T4CT (soon to be discontinued and new orders will get £12K incentive) as a loaner which if I'm totally honest was zippy enough. Ride was on 21" with Goodyear and felt harsher than my GTS ST which is just perfect. Did make me rethink that going down the range takes you to a level that has the key Porsche performance ingredients. Reported range 139 miles at 50% - clearly a winner.

Service and campaign took 4 hours from drop off to pick up.

In US ARB7 is HV battery recall for Taycans that have battery data monitoring done OTA. Two parts to that recall: Dealer checks condition of the battery, and installation of new battery monitoring software.
WRS0 is the equivalent "workshop campaign", but not a "recall", for the same work as ARB7 in other countries.

The question for owners who have had WRS0/ARB7 applied by the dealer:
Did both parts of the work get done, or did the dealer only check the battery condition?

An interesting thing happened yesterday. I had a lot of driving to do, and charged to 99% at an EVSlow station. (I joke, but it was actually a 350kW station and I had a great 245kW charge.)

Anyway, after stopping the car threw a yellow error indicating battery service necessary. The car worked fine afterward.

I wonder - did that new OTA battery monitoring update detect a fault? Or was this one of those random weird failures that comes and goes?

In other words, does improved battery monitoring software (if your car got it yet) actually do anything other than recommend more visits to the dealer?

Not sure whether it was this OTA battery update or the fact that I rebalanced my cells but my battery at 95% only had an indicated range of 135 miles. Two days after this the red circle of death.

Here goes round two of battery saga for my self. I will personally not accept another battery repair. I want a new battery. Last battery repair of 12 cell modules replaced only resulted in 15 months of problem free operation.

Good luck with that - I hope you are successful. Keep us in the loop.

Anyone else have both ARB6 and ARB7 linked to their VIN?

Well I got the OTA update which specifically said it was for battery monitoring. I’m tempted to try another deep 100% charge to see if the error fires again.

As we know, these cars are buggy and sometimes throw the occasional weird error.

I guess my assumption is that since it threw the error, my car has a battery issue and a more urgent recall will follow.

Unless it was a fluke.

WRS0.... OTA ????

Maybe the car is reporting that you have violated the advice to only charge to 80%! As per advice in the letter.

I had the WRS0 software installed yesterday as part of my 2 year service.

As per the letter to UK folk the same software update would have been applied OTA and only if connectivity to the car was an issue then the work would be done under a recall notification.

Battery was checked and software installed. All good.

thats almost 1 month per cell. Be thankful /s

how dare you go beyond your local supermarket.. we told you to keep it at 80 /s. So sick of this. I've had like 12 recalls and counting. THis is a nightmare.

Also since the last update, ive had the porsche loading screen - i turned the car off and on and rebooted (2 finger) - didnt do anything. Still stuck.
