High-voltage battery flat after standing and seized rear brakes on the e-up!

Engine / equipment

Volkswagen e-up! (also the Seat Mii electric and Skoda Citigo e iV, which are the same car)

Period mentioned

2013–2023

Symptoms

After several days standing, the high-voltage battery turns out to be flat; rear brakes that stick, rub or have rusty discs.

Possible cause described

The German Gebrauchtwagenberater guide explains that the e-up!’s high-voltage battery was often found flat after a long standstill: a software fault drained the 12 V battery and the high-voltage battery then had to recharge it; a software update fixes it. Because regenerative braking does almost all the work, the discs are hardly used, collect dirt and rust, and the brakes, especially at the rear, can seize. The KBA also recalled 122 e-up! cars over damaged cells, replacing the whole battery.

Check for the garage

Ask the dealer whether the software is up to date and the battery campaign has been done; check the 12 V battery and ask for the rear brakes to be cleaned at every service. Braking hard now and then helps clean the discs.
