The Hybrid and Electric Vehicle Repair Alliance provide a technical overview of the electric version of the VW Up!
Introduced in 2013, the electric version of the VW Up! hasn’t been a huge success in the UK. Original models were known internally as BE1. 2017 brought a minor update and a new designation, BE2. The Up! was designed to be built as both a petrol and electric car. The EV uses a different floor pan to the petrol version, allowing the high voltage battery to take up space under the floor. Further modifications to the floor and body offer protection to the battery and high voltage cabling. In the absence of engine noise, rear wheel arch liners are fitted and extra soundproofing is added in the front wheel arch area.
Dealer support for the e-Up! is pretty poor, with very few dealers offering sales, servicing or warranty repairs, which is partly why we believe independents have an opportunity.
BATTERY AND CHARGING
e-Up! has a 18.7kWh Lithium-Ion battery and 3.6kW on-board charger and Type 2 connector. Some models have DC rapid charging via CCS. The battery pack does not have a cooling system.
MOTOR AND GEARBOX
The e-Up! uses a 270, LS1 motor with engine code EABA, and single-speed gearbox 0CZ. If the motor, EV ECU or inverter are replaced, reprogrammed or reset, the motor will need to calibrate before operating correctly. This will happen automatically the first time the vehicle is driven, but the car will drive with reduced power until the calibration is complete.
The gearbox uses a mechanical parking lock operated by a cable from the gear selector.
The e-Up!’s DC-DC converter is built into the inverter assembly. The vehicle uses a VAG generation V immobiliser. The components of the immobiliser are the Motor Control Unit (J623), EV control unit (J841) and the instrument cluster (J362 inside J285).
With the exception of the curved LED front DRLs, the lighting system is the same as other versions of the Up! and uses traditional filament bulbs.
e-Up! may also be fitted with a 12V heated front windscreen.
The e-Up! uses an app called e-Manager to see battery state- of-charge, switch on remote climate control and change charging settings. These functions are controlled in the car by the Emergency Call control unit J949, also using location information from the navigation system sent via CAN.
CABIN HEATING AND HIGH-VOLTAGE COOLING
The e-Up!’s cooling system is in some ways similar to that of a combustion engine. One half of the cooling system pushes coolant around the inverter, charger and motor, and of course radiator, whilst the other half pushes coolant through the high- voltage PTC heater and heater matrix. The two are, however, linked by sharing the same expansion tank. Coolant used is G40.
Air conditioning is standard which, of course, uses a high- voltage electric compressor.
The e-Up! features an artificial noise generator behind the front grille. This is controlled by ECU J943, located under the passenger seat.
The e-Up! uses an Electromechanical Brake Servo known as eBKV, with a pressure accumulator. The accumulator contains a pump and is used to optimise regenerative braking in conjunction with dual position sensors on the brake pedal. Discs brakes are employed on the front, with drum brakes on the rear.
Brake fluid can be changed or bled using a 2-bar pressure bleeder. The procedure is standard, with the exception of an additional brake bleeder on the pressure accumulator. This should be bled once the four wheel brakes have been bled.

HIGH VOLTAGE DISCONNECTION
High Voltage disconnection requires diagnostic equipment. Select the disconnection procedure and follow instructions given. In an emergency, follow instructions in emergency response guide (pull out labelled fuse).
