Rough Repair Cost

Independent workshops typically charge R22 000-R35 000 for this, depending on exactly what's needed. The full independent-vs-dealer breakdown is in a full AutoLytiQs report.

What To Check

Yes, due to a highly prominent acoustic change. Once the chain has ground through the plastic guide shoe, it rides directly on the metal tensioner plunger, producing a loud, high-pitched whistling/buzzing sound like a mechanical supercharger, rising and falling directly with RPM. Easily heard by an average driver at idle - no cold start or special equipment needed.
