Diagnosing a failing turbo on an Opel Astra 2.0 CDTI before replacement
Before ordering a new turbo for an Opel Astra fitted with the 2.0 CDTI diesel engine, it is essential to confirm that the fault lies with the turbocharger and not another component. On this A20DTH engine, the most common signs of a turbo nearing the end of its life include a gradual loss of power, an illuminated engine warning light, an unusual whistling noise under acceleration, or exhaust smoke (black or blue). You should check the boost pressure, ensure there is no radial or axial play on the turbine shaft, and look for any oil in the intake hoses before concluding that a full replacement is necessary.
Compatibility of the new turbo with the Opel Astra 2.0 CDTI
This new turbo is compatible with reference 788778-5003S, intended for Opel Astra models fitted with the 2.0 CDTI 130 engine, under engine code A20DTH, diesel fuel type, and an engine capacity of 1956 cm3. Before placing an order, it is recommended that you check the reference printed on the old turbo or on the vehicle's registration document, as certain Astra variants may use different turbos depending on the power output or generation.
Exchange basis and warranty for this Opel Astra turbo
This turbo is sold on an exchange basis: return of the old turbo is required, in accordance with our Terms and Conditions. It is only collected after the new turbo has been delivered and fitted, so that the vehicle is not left off the road during the process. The part comes with a 12-month parts warranty, subject to fitting being carried out by a qualified professional. Payment can be spread over multiple instalments, in up to 10 instalments.
Fitting advice for the A20DTH engine
Before fitting the new turbo to the A20DTH engine, it is absolutely essential to check the oil circuit: cleanliness of the strainer, correct lubrication pressure, and no blockage in the feed hose. The boost and oil hoses must be inspected for cracks or hardening, and the air intake and air filter must be checked to prevent any ingestion of particles. It is also advisable to check the condition of the intercooler, which is often responsible for premature failure if it is retaining oil. On first start-up, it is recommended to prime the turbo with oil to ensure immediate lubrication of the bearings before the engine is started.
