A 120,000-km Mercedes E300 stored P06DA00 and kept its engine warning lamp on. Oil found at the oil-pump control solenoid connector led to solenoid and anti-siphon lead replacement, terminal cleaning, oil-pan resealing, and a successful initial code-and-warning recheck.
A Mercedes GLS 450 developed unstable hot idle, intermittent stalling, and a strong gasoline odor. Fresh fuel at the injector seats and deformed injector seals confirmed the leak; the workshop cleaned the injectors, installed seal kits, and reported leak-free static and dynamic pressure-hold checks with stable rail-pressure feedback.
A 2022 Mercedes A200 displayed normally in Park but flickered whenever Reverse or the camera was selected. The workshop traced the condition to the reverse-camera control module, replaced and coded it, then repeated the original trigger with a stable image and no flicker.
A 2012 Mercedes R350 stopped cooling after a history of refrigerant leakage. Inspection found a seized compressor shaft, a slipping pulley, and very little oil in the removed unit. A DENSO compressor was installed and the center-vent temperature reached 8.4°C and continued falling.
A 2021 Mercedes A200 with 49,000 km had hard starting, severe idle shake, and metallic impact noise while P033815 named the crankshaft-position sensor circuit. Transmission removal exposed a broken dual-mass flywheel that had damaged the target/sensor area; replacing the flywheel and sensor restored a stable signal and idle.
