What This Product Does

The knob provides the hand-operated interface for the left rotary control on the PCM radio panel. It is an individual control-panel component, rather than a replacement radio, navigation unit or amplifier.

Functions

• Provides a gripping surface for operating the left rotary control.
• Replaces a worn or damaged knob on the specified PCM panel.
• Refreshes an ageing interior touch point without changing the multimedia system.
  
  

Technical Details

• Position: LEFT on the PCM control panel; this does not indicate the vehicle's driving position.
• Finish: matt black.
• Specified system compatibility: PCM 2&3.
• Left-hand diagram reference: 99764220100A05.
• The supplied diagrams identify 99764220200A05 as the separate right-hand knob, not the left-hand component.

Symptoms of Fault

Relevant signs include a tacky or peeling surface, visible deterioration, cracking or damage to the knob's attachment. An unresponsive radio control requires diagnosis: replacing the external knob alone may not resolve an internal electrical fault.

Why Replacement Matters

Renewing a damaged knob addresses wear at a frequently handled cabin control. Inspect its mounting point before fitting so that damage to the underlying mechanism is not overlooked.

FAQs

Are the left and right knobs interchangeable?
The supplied diagrams give them different references. Select the LEFT version for this application.

Will this repair every PCM control problem?
No. A worn external knob and a faulty internal control are different issues; establish which component is damaged before replacement.
