A Volkswagen Golf 7 GTI came to us with a coolant leak and rough running.
What were the symptoms?
- Rough running
- Coolant loss
How did we diagnose and repair the Volkswagen Golf 7 GTI coolant leak?
- We traced the coolant leak to the water pump.
The original water pump should be replaced every 100,000–120,000 km or 5 years.
- After carrying out a series of measurements, we found that worn fuel injectors were causing the rough running.
This is a common problem with 1.8 and 2.0 TFSI engines across almost all generations.
- We replaced the auxiliary belt drive and the alternator overrunning pulley.
