The two throttle valves 7.03703.38.0 and 7.03703.39.0 are identical technically. The throttle valve 7.03703.38.0 also has a vacuum connection. Competitors and vehicle manufacturers (OE) only offer the version with vacuum connection (036 133 062 L, 408-238-321-006Z). Depending on the vehicle (see table), you may have to seal the vacuum connection with an additional rubber cap and a hose clamp (only available from OE).
- no sealing of the vacuum connection required
- no potential leakage
- no additional components need to be purchased from OE
Please note the exact distinction according to chassis number, engine ID code and model year.
The throttle valves must be “taught in” after installation. Always observe the instructions given by the vehicle manufacturer.
