Is there a service where I can check my VIN against that KBA ARB6 recall list of 68 157 other vehicles? Or is the best option just to ping the local dealer? I have a '21 4S and haven't heard a peep.

Looks like nobody in north Europe received any notification letter.

speculation is that regulations in those countries doesn’t allow them to impose restrictions such as “80% charge only” or where to park; as that’s preatty much the only purpose of the letters as the recall solution is not avaliable yet

@works In the UK, neither the Porsche GB site VIN look up or the government vehicle safety regulator show the current recalls against my car, so this is not updated on a timely basis by Porsche and/or the regulator.
You could try the VIN look up facility on the Finnish Porsche site and on your government vehicle safety regulator site. If you find nothing, contact the Porsche importer Customer Service or your local dealer for info.

Access to the VIN range would be interesting
The only place I’ve seen a range published is on the NTHSA site. The VIN includes a country code so I’m not sure you if you can use the USA VIN range for GB cars.
But the production dates and volumes published there and on the EU site indicate all cars manufactured up to 1/3/24 should have either a WRS0/ARB7 or WRS1/ARB6.

I sent this to the UK vehicle safety authority on Monday:

Q1. There is nothing 100% granted in this world. Do condoms protect 100% of pregnancies? They don't. 99% of them perhaps so.

Having that said, the on-board monitoring update is a response from Porsche included in ARB6/ARB7 (October 2024) to my August 2024 report in Rennlist. https://rennlist.com/forums/taycan/...ive-with-shorted-out-battery-modules-wtf.html

What Porsche is trying to do, is getting the car to emergency shut down the HV system when something goes wrong inside the battery (including isolation as I reported). Basically the contactors in the battery isolator open, totally isolating the battery from the car and leaving the car's HV system voltage free. Similar to when the breaker trips at home. In this condition of the battery being isolated a thermal event is extremely rare.

Only when the battery has reached a critical state there is a possibility for any slight disturbance to cause a thermal event (hence why cars flagged as critical need to be quarantined by the dealer for a few weeks).

If the battery is not in critical state (even if it has iso problems, or even water inside) the risk of a thermal event we could argue exists only during high speed DC charging or right after. For this reason having the car "trip the breaker" is extremely useful.

Q2: This refers to my report dated August 2024 in Rennlist whereby Taycan BMS fails at correctly assessing iso faults (electricity leakage problems) and fails to emergency shut down HV system timely.

Q3: Refer above.

Q4: Unknown yet, I dont have sufficient experience with the new facelifted model. However the battery it uses are still LG. So it is expected some part of the problem will remain. Macan EV has switched to CATL batteries (Chinese) which I much prefer over LG to be honest.


ONE MORE thing that needs to be clarified is that in all cases it's always LG who is responsible for the batteries. Whenever Porsche replaces your battery under warranty it needs to be approved by LG as they are the ones paying Porsche for it.

Everything falls under LG responsibility, it's their battery, and any problems related to it are their fuck up as well. NOT Porsche's. This needs to be stressed clearly enough. \

8-9 years ago Porsche started developing the Taycan you could say that theoretically at least LG was top of the game. Nowadays tho, they could only dream of even coming close to Chinese batteries such as BYD and specially CATL. Hence why the new Macan EV has switched to CATL.

@ct14garage - thanks for the info and reply.
Have you seen anything which describes what Porsche is attempting to do with the on-board monitoring update, or is your info supposition, what you believe is needed?
100% agree that LG is responsible for the defective battery modules, but as vehicle manufacturer, Porsche is 100% accountable for assembly and for the overall HV battery product safety (monitoring) design, even if they also sub-contract some or all of that too. Who produces the Battery Management System?

And yet there appear to be MY24 (J1.1)vehicles with no campaign references. presumably MY24 production would be August 23 after summer shut down, as per normal. Some J1.2s escaped into the wild in June 24 so not 'the usual' model year switchover............
