Diagnosing a failing turbo on an Audi A3 1.9 TDI before replacement
Before ordering a reconditioned turbo for your Audi A3 fitted with the 1.9 TDI 105 engine, it is essential to confirm that the fault lies with the turbocharger itself and not with an ancillary component of the intake or exhaust circuit. Reading fault codes with a diagnostic tool, checking boost pressure, and visually inspecting the turbo shaft (axial play, oil traces in the exhaust or intake) will help rule out false leads before any replacement is carried out. On this BLS engine, progressive power loss, an unusual whistling noise, or blue smoke from the exhaust are characteristic signs of turbocharger wear.
About the reconditioned turbo for the Audi A3 1.9 TDI
This reconditioned turbo is compatible with reference 03G253019K, fitted to the Audi A3 with the 1.9 TDI 105 engine, engine code BLS. It has been fully inspected and reconditioned to a rigorous process in order to restore performance in line with that of an original turbo, while meeting the operating tolerances of the BLS engine.
Checking compatibility with your Audi A3
Before placing an order, we recommend checking the reference number on your vehicle's old turbo, as several versions of the 1.9 TDI may have been fitted with turbos carrying similar references. This check avoids any compatibility errors and ensures a straightforward fitment on your Audi A3.
Exchange basis and warranty
This reconditioned 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 to your Audi A3, so that the vehicle is not left off the road during the process. A 12-month parts warranty applies, subject to fitment being carried out by a professional.
Common causes of failure on the BLS engine
On the 1.9 TDI 105, turbo failure is often linked to insufficient lubrication, poor-quality engine oil or missed oil changes, a clogged air filter, or a damaged intercooler. Driving with sudden high-rev bursts without allowing the engine to cool down before switching off can also accelerate bearing wear.
Points to check before fitting
- Cleanliness and good condition of the oil circuit (hoses, feed and return lines)
- No leaks or cracks in the air intake hoses
- Condition of the air intake and air filter
- Priming the turbo with fresh oil before the first start, to avoid running dry
Following these steps is essential to the service life of the reconditioned turbo fitted to your Audi A3.
Payment options
You can pay for your reconditioned turbo in instalments – pay in up to 10 instalments to spread the cost.
