- How the car detects it
- P2828 serves as the catch-all code for solenoid K and is normally refined by a failure-type byte or replaced by one of P2829 to P2830. Mercedes-Benz is the maker found to name it directly: on the 8G-DCT dual-clutch gearbox of model series 118, 177 and 247, P282800 denotes a malfunction of pressure regulating valve 10 and P282B00 an electrical fault of the same valve. Both belong to the IPR routine in XENTRY Diagnosis, which Mercedes set up because many repairs on transmission 724.1 had not solved the complaint. GM uses K on the 2023 Corvette dual-clutch box for the selector pilot valve, but only with the specific codes. Since K may be a clutch, selector or cooling valve, effects range from rough shifts to missing gears.
