Question type: Maintenance & Repair

How many miles can an a4 be driven before the
turbo should be replaced?

2 Answers


It's really not a mileage thing, more of a pressure output, when the boost pressures start to drop from what they normally are, then it's time for a replacement. Or if it starts to blow oil into either side of the turbo.

The turbos can/will last over 100k miles with proper maintenance and scheduled oil changes. Also, changing the oil feed lines every 70k miles will give it a lot more life.
