My wife's 2017 Volkswagen, with only 160,000 very gentle km on it (100,000 miles) suddenly had a warning light come on. It seems that the sensor on the turbo charger had gone bad, but the only way to fix it is to replace the entire turbocharger, close to $5,000.
From what we have read, Volkswagens of this age start to have large numbers of very expensive repairs. Lesson learned, she got rid of the Volkswagen and bought a hyundai.
