Hello,

I got a Mercedes A220 built in 2021 (US model) and recently the engine lamp came on. We had pretty bad frost in Louisiana 2 weeks ago (-11 degrees Celsius), and I used my AC today again, when the engine lamp popped up.

The error codes are:
P13C2(04)
Control Unit 59
Status: Confirmed, Test failed since last DTC clear

P1462(64)
Control Unit 58
Status: Pending, Confirmed, Test failed since last DTC clear, Test not completed during this operation cycle
A/C Pressure Sensor Circuit Voltage High

P02FF(02)
Control Unit 58
Status: Test failed since last DTC clear, Test not completed during this operation cycle

P1462
Control Unit 58
Status: Permanent
A/C Pressure Sensor Circuit Voltage High


I refilled the A/C low pressure line with a little bit of freon. I would describe myself as pretty hands-on more with Toyota and VW though.
The A/C worked yesterday, after refilling the freon and driving around the A/C stopped completely working.

Does anyone have an idea if these pressure sensors are going out on the A220 model?
