1. Good oil, changed on time
Turbo bearings run on a film of oil. Dirty or old oil is a turbo's number one enemy. Follow the manufacturer's oil spec and change interval.
2. Go easy on a cold engine
Right after start-up the oil is still thick and reaches the turbo slowly. Avoid high rpm for the first few minutes.
3. Let the turbo cool down
After fast or heavy driving, do not switch the engine off straight away — let it idle for a minute or two so the turbo cools down.
4. A clean air filter
Dust and fine particles wear the compressor wheel. Replace the filter on time, especially on dusty roads.
5. Check the hoses
A crack in the intake or a loose clamp makes the turbo work harder.
6. Do not ignore fault codes
P0299, P0234 and actuator codes are often fixed by calibration. Wait too long and a small problem becomes a big repair.
