The symptoms of a faulty wastegate valve in the Magotan are: 1. Severe suction when opening the oil filler cap; 2. Sudden emission of large amounts of exhaust smoke, white at idle and blue during rapid acceleration or heavy throttle; 3. Accompanied by a strong burning rubber smell; 4. Causes engine idle vibration. The Magotan is a mid-sized 4-door 5-seater sedan with body dimensions of 4865mm in length, 1832mm in width, 1471mm in height, and a wheelbase of 2871mm. It is equipped with a 1.4T turbocharged engine and a 7-speed dual-clutch transmission, delivering a maximum power of 110 kW and a maximum torque of 250 Nm.
Over the years of driving the Magotan, I've noticed that exhaust valve failure is quite common. The main symptom is large amounts of blue smoke from the exhaust pipe, especially more noticeable during acceleration. There's a significant power loss, the throttle feels sluggish when pressed, and fuel consumption increases accordingly. It's most obvious during cold starts - the engine shakes like it's dancing, and occasionally the check engine light comes on yellow. Once my car had unstable idling with the tachometer needle jumping up and down erratically, and inspection revealed a cracked exhaust valve causing air leaks. Another hidden issue is unusually fast oil consumption - needing to top up half a liter every 2,000 kilometers, with exhaust fumes becoming pungent. I recommend getting it checked at the first sign of abnormality, otherwise it could damage the catalytic converter which would be more expensive to repair.
