The Alfa Romeo Giulietta Mk1 (940) 2010-2020 was Alfa’s compact five-door hatch, offered with a range of MultiAir petrol and JTDM diesel engines over its long production run. After routine servicing this generation typically needs the oil service light reset so the maintenance counter starts a fresh interval, along with a maintenance reminder reset on later cars. You may also want a TPMS reset after adjusting tyre pressures, a brake pad wear reset following new pads, and electric window initialisation if the auto up/down function stops working after a 12V battery reset. The precise steps shifted across the 940’s facelifts and trim levels, so confirm your build year first. Choose the reset procedure you need below to follow the correct method for your Giulietta.
