how to fix a sticking throttle in my Volkswagen Golf MK5 (2004-2008)?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety during repairs.

2. Clean Throttle Body

• Tools Required: Throttle body cleaner, soft cloths, screwdriver set, and a small brush.

• Wipe off any excess cleaner and ensure there are no obstructions.

3. Inspect and Adjust Throttle Cable

• Tools Required: Socket set, pliers.
• Locate the throttle cable and check for any signs of damage or binding.
