I have one of those "lifetime" guages that reads in PSI to a 0.5 PSI
accuracy. The beeper sound was weak, then today it showed an "L"
instead of a pressure reading, so I removed the CR2032 battery, and
put a new one in a few hours later.
Now it shows "01.0" when I read something that is at least 30 PSI, and
does not beep.

Does the unit need calibrating, or pitched away? Will BMW honor any
sort of lifetime warranty? TIA

Try taking the battery out for 30s and then reinsert it.


Tried it, waited overnight, did the "blip" zero calibration test,
still shows "01.0" for about 10-15 seconds. Original battery causes
the same. I have the card that came with the gauge. Says 20 year life
on the battery, how to zero the gauge and to send it to the factory on
seeing "L" for a free replacement. China? Right. I'll take it and
the receipt to the dealer and swap it out.
I'm not a believer in lifetime batteries or "no user servicable parts
inside."
Thanks!
