The second-generation Volvo V40 (525) 2012-2019 was a premium five-door hatch on the P1 platform, notable for its pedestrian airbag and Drive-E efficiency engines. Its electronics expect acknowledgement after workshop tasks. An oil service reset clears the maintenance reminder once the oil is changed, and an inspection reset covers the longer schedule. New brake pads need the brake pad wear reset, tyre pressure changes call for a TPMS reset, and a replacement battery should be registered so the stop/start and charging logic recognise it. Steering angle calibration follows alignment, and electric window initialization restores automatic operation. Pick the relevant procedure for your V40 from the options listed below.
