New battery function - engine start or not?
Just replaced the battery on my D4. I ran the "battery replacement" function from the Service/Test -> BCM menu.
The function turns the ignition off, and then turns it back on again. Should I let the ignition switch on without pressing the brake pedal, meaning the engine does not start, or put my foot on the pedal so that it does start?There are two rules for success,
1. Never tell everything you know.
D4 gone!

I don't know for sure either.
The message you get has always puzzled me so I usually start it but it does seem a little daft when "it" is capable of cycling the ignition itself.In today's world, if you contribute something, you don't contribute enough. If you contribute nothing, you receive everything.

I think (but am happy to be corrected) that the routine won't start the engine even if you have the pedal pressed. I think it will only turn the ignition on without running the starter.
When I changed my D4 battery exactly 3 years ago I didn't press the pedal.MY2022 D5 HSE D300 - with extra nice bits added

It does start the engine if you keep your foot on the brake pedal. Hope you’re well Jonathan.There are two rules for success,
