Turbocharger
Turbine turbocharger (2) driven by the pressure of the outgoing exhaust gases. Impeller (1) on the suction side is driven by a passing shaft at a high speed, whereby the intake air can be condensed. Significantly more air enters the combustion chambers, providing more power or more torque. As soon as the pressure in the suction chamber becomes higher than desired, the vacuum adjustment box (3) boost pressure opens the bypass channel and passes part of the exhaust gases past the turbocharger into the exhaust system. in the control tube (4) built-in boost pressure control solenoid valve to take into account the effect of altitude on boost pressure.
- A) Air;
- b) waste gas.
If the Audi Turbo develops noticeably reduced power or the maximum speed is not reached, the cause may be a faulty turbocharger.
Before troubleshooting, you need to make sure that the engine and injection system are in good condition.

Your help
|
A.
Parts of the exhaust and turbo system are leaking
|
1. Air hose between compressor and intake manifold above radiator
charge air leaky or disconnected
2. Leaky area between intake manifold and cylinder head 3. Leaky flanges at the intake manifold 4. Leaky area between exhaust manifold and cylinder head or turbocharger |
B. Faulty turbocharger | 1. Check boost pressure. If it's too high:
check the boost pressure control solenoid valve, check boost pressure control valve vacuum box. If either in working order, interrogate the fault memory in the car 2. Boost pressure too low: check the boost pressure control vacuum box. If she's right, replace turbocharger |
