Variable-geometry turbocompressor specialists
Audi, Volkswagen, Mercedes, BMW, Skoda, Renault, Toyota, ...

When your variable-geometry turbo shows pressure fluctuations or is seized, systematic replacement is not the only solution.

Depending on the condition of your turbo, we offer two solutions :

Maintenance level no. 1

• Removal of the turbine casing

• Removal of the variable system and its accessories

• Removal of the compressor casing

• Ultrasonic inspection of the turbine casing, variable system and accessories

• Complete degreasing in an ultrasonic bath

• Rinsing

• Descaling in an ultrasonic bath

• Rinsing

After cleaning the variable system and its accessories in the two ultrasonic baths, the turbine casing is sand-blasted to finish the cleaning process.
It is then immersed in phosphating bath to prevent rusting, which restores its as new appearance.
We also systematically grind the sealing surfaces of the casing (collector and exhaust sides). The rotor assembly is cleaned and inspected on the V.S.R. test bench (noise, vibration and sealing inspections). At this stage, if the rotor assembly is out of tolerance, we notify you of the problem. If there is no particular problem, we rebuild the assembly and check the actuator pressure.
- We then dispatch your turbo.
- Delivery lead time: 24/48 hours from receipt of your turbo on our premises and from your agreement to proceed with work.

	Maintenance level no. 2 Maintenance level no. 1 + complete overhaul including replacement of the service kit (bearings, segments, seals and other parts as necessary). Before proceeding with level n°2, we send you a quote by fax or e-mail.
Optional services We can supply: - electro-valves, flowmeters and EGR valves - a reassembly seal kit for each turbo. For example, the seal kit for a TDI110 CV turbo P/N 038253019A includes the collector, exhaust outlet, EGR valve, oil scavenge and oil inlet seals.
