Start with the facts.
Start with your chassis code and model year. R170, R171, and R172 components should not be assumed interchangeable. The engine, production date, connectors, and left/right position can all affect compatibility.
Before you make arrangements.
Find the number on the existing part and take a clear photo. Send a wider photo showing where it sits in the car, plus close-ups of connectors and mounting points. Ask Doc to confirm fitment before paying.
These notes help prepare an inquiry. Model-specific technical procedures and repair decisions should be confirmed with a qualified specialist.
