We recently serviced a high-mileage 2012 Volkswagen Golf R for drivability issues, carbon buildup, and aging suspension components—common concerns for the Mk6 Golf R platform and other direct-injected VW models.

Carbon Cleaning and Fuel Injector Replacement

Like many direct-injection VW engines, the 2.0L TSI suffers from carbon buildup over time. We removed the intake manifold and found heavy deposits on the intake valves, restricting airflow and causing rough starts and hesitation under load.

With the manifold off, this was the ideal time to install new OEM fuel injectors along with all-new seals and install hardware. Replacing injectors during a carbon clean is highly recommended to prevent future leaks and misfires. The result was dramatically cleaner intake ports and restored flow to all four cylinders.

Ignition Refresh: Spark Plugs and Coils

The original spark plugs were still in place, clearly overdue. We replaced them with fresh NGK Laser Platinum plugs and installed new ignition coils. We also noted the engine oil was slightly low and topped it off during the service. Small steps like these make a significant difference in reliability and drivability.

Suspension Work: Control Arms, Ball Joints, and Shocks

Suspension components were also showing their age. We replaced the front lower control arms and ball joints, then performed a four-wheel alignment to bring the geometry back into spec. The rear received Bilstein B8 Sport shocks and new upper shock mounts, restoring ride quality and handling stability.

Bringing It All Together

This Golf R now runs smoother, idles cleaner, and handles the way a proper hot hatch should. It’s a great example of what targeted maintenance and mechanical refresh work can do for a high-mileage performance VW.
