The two-cylinder turbo petrol of the 500 and Panda. An unusual twin is naturally a bit rough at idle, but power loss under boost is a workshop signal.

Random/Multiple Cylinder Misfire Detected
The engine control unit detects misfires occurring randomly across multiple cylinders, meaning combustion is failing intermittently in more than one cylinder.
Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor B)
A second camshaft sensor on bank 1 does not match the crankshaft position the ECU expects, pointing to a timing discrepancy on that cam.
Coolant Temperature Below Thermostat Regulating Temperature
The engine takes too long to warm up - the ECU sees coolant temperature staying below where the thermostat should regulate it.
System Too Lean (Bank 1)
The engine is getting too much air or too little fuel on bank 1 - the ECU has hit the limit of its ability to compensate.
Turbocharger Overboost Condition
Boost pressure exceeded the safe limit - the wastegate or boost control is not relieving pressure.
Fuel Pressure Regulator Performance
The fuel pressure regulator is not maintaining pressure within the expected range, even though its control circuit tests electrically fine.
