I don't know the answer but I always assumed they were only for emergency use. I wouldn't use one regularly. And I gave up with foot pumps ages ago when I had a leaky tyre on the Frontera. Big tyres take AGES to pump up.mik wrote: Thu Mar 21, 2024 8:52 amHave one of those in the E-Tron. Pulled it out for the first time a month or so back, switched it on - ran fine. Moved to next tyre - switched it on - nothing. Not sure if it tripped out or died.
I've been through a couple of Ring digital electric pumps since. They're OK. Being able to set the required pressure and leave it running is a very nice feature.
