DIY replacement of ABS Wheel Speed Sensor (multiple dash error)
Great write up thanks!
You say that you "added one to the battery code" - could you just explain that a bit more? The existing Varta battery would be coded into the vehicle. Is that the same code that's printed on the battery, or is the code displayed your vehicle specific and you just took a pot-shot at adding one?
Hopefully next month I will be reunited with my MY18 Macan S which has been sitting in a garage in France for a year waiting for me to return it to UK for an MOT! Obviously the original battery is totally bug***ed. Some people here have suggested I give it a try with my C-tek conditioner and of course I will, but expecting to have to start again with a brand new battery, this gadget looks like it might be my saviour.
If I could just pick up a new battery locally and install it as you suggest, can I expect issues as the car will be dead initially? Would connecting a "spare" battery to the under-bonnet terminals be any use in this situation?
Thanks for any more advice!

I'm going to ask a stupid question now, does the new battery not come with a code on it that you can use?

That makes sense, I wonder if you can just re-use the same code if you buy the exact same spec of battery.
No point. The Bem alters the charge rate and voltage depending on the age and other factors. Using the same number would make the Bem think you still have the old battery and so would treat it like it was in it's way out. Resulting in battery short life. Better not using a code at all I think in that case
A good write up of battery replacement over on pelican:

Earlier this week, experienced the exact same fault with my wife's VW Tiguan. On start-up every safety system warning light came up together with a message (for each system) saying it was no longer available. As it happens, the car was already booked in for its last service before expiration of warranty so just rang the dealer and added this problem to the other work. Fault turned out to be caused by an ABS speed sensor failure.
Reason for posting is I can't see why a single point failure should disable all the car's safety system. I don't know whether this is just confined to VW Group software or is universal.
