A/C Weak on Your Mercedes? Replace the ZEXEL Compressor Valve for $54.
The A/C compressor control solenoid valve for ZEXEL DCS17 and DCW17F compressors (used in Mercedes-Benz C-Class, E-Class, CLS, CLK, SLK, Vito, Viano, and Sprinter with Valeo compressors) regulates refrigerant displacement. Solenoid failure causes weak cooling, erratic A/C cycling, or complete A/C loss.
✓ What You Get: A/C compressor control solenoid valve for ZEXEL DCS17 / DCW17F (Valeo) compressors on Mercedes-Benz — restores full A/C cooling performance.
What's Included
- 1× A/C compressor control solenoid valve (ZEXEL DCS17 / DCW17F)
- O-ring seal(s)
Why Replace?
- Restores Cooling: Faulty solenoid reduces compressor displacement and refrigerant output.
- Stops Erratic Cycling: Failed valve causes compressor to engage/disengage without reaching cabin temperature.
- Saves $250+ vs Compressor: New Valeo/ZEXEL compressor $300+; solenoid fix costs $54.
- 30-Minute Job: Remove compressor front housing, swap solenoid, reassemble.
Vehicle Compatibility
| Make | Models | Compressor |
|---|---|---|
| Mercedes-Benz | C-Class, E-Class, CLS, CLK, SLK | ZEXEL DCS17 / DCW17F (Valeo) |

About This Control Valve
ZEXEL DCS17 / DCW17F A/C compressor control solenoid valve for Mercedes-Benz vehicles equipped with Valeo variable-displacement compressors. The ZEXEL DCS17 and DCW17F are variable swash plate compressors where the solenoid controls displacement ratio — the solenoid is the primary wear component and the most common cause of A/C performance degradation on these Mercedes-Benz platforms.
⚠ Verify Compressor Model Before Ordering: Confirm your compressor is a ZEXEL DCS17 or DCW17F before purchasing.
