We establish the cause before repair. The set of checks depends on the complaint and the first results.
Advanced computer diagnostics
PIWIS, ODIS, VCDS: fault codes, live control-unit data, active tests, adaptations and coding.
Borescope inspection
A camera look into the cylinders without dismantling the engine: wall condition, carbon deposits, signs of wear.
Smoke test
Finding leaks in the intake tract and vacuum lines by where the smoke escapes.
Compression test
Comparing pressure between cylinders helps assess the rings, valves and head gasket.
Oil pressure test
Checking pressure in the lubrication system helps separate pump or wear problems from a faulty sensor.
Chemical cooling test
Testing the coolant for combustion gases helps when a head-gasket leak is suspected.
Timing and cooling inspection
Inspection and measurement of the timing drive, water pump, thermostat and hoses to define the scope of replacement.
The set of checks depends on the complaint and the first results. These procedures are not included automatically in every visit: additional checks, their scope and cost are agreed with you in advance. No single test guarantees that every fault will be found. When booking, please give the model, year, engine and symptoms.
