The risks of driving a Volkswagen car with an Overhaul problem can vary depending on the nature of the problem. In general, the risks can include a loss of power and control, increased fuel consumption, and engine failure. When an engine has an Overhaul problem, parts may be worn out or broken, leading to decreased performance and fuel efficiency. Additionally, because the engine starts up and runs while parts are damaged, the car may not run properly and could be unsafe to drive. This can include everything from the engine stalling, to reduced breaking power, to the engine suddenly shutting off when it is hot. Ultimately, driving a Volkswagen car with an Overhaul problem is not recommended, as it can put the driver and other people on the road at risk.
