Audi A4 1.9 & 2.0 TDi (DPF Model) Turbo Charger Unit Repairs

Why They Normally Fail
The Audi A4 1.9TDi and Audi A4 2.0TDi, both being Diesel Particulate Filter (DPF) models commonly suffer problems with the turbo charger unit failing. Other common problems for the Audi A4 1.9 & 2.0 TDi (DPF model) is Diesel Injectors failing & Engine Oil contamination.  The reason they fail is most commonly due to the Diesel Particulate Filter (DPF), located in the exhaust it is designed to trap soot / ash particles and by doing so, it restricts the airflow of exhaust gasses which in turn will increase the back-pressure. Excessive and long-term back-pressure will put a lot of strain on mechanical components and with the turbocharger being directly connected to the Diesel Particulate Filter, that is most likely the first unit to show signs of failure.

If it has not been properly maintained i.e. regular oil changes and allowing the engine time to warm up a little before a quick run. When you start a turbo engine from cold, the oil will be thick and gunky which takes time to travel around all components. For this reason, it is suggested that when starting the vehicle, allow 1-2 minutes before moving from a cold start. This will give time for the oil to warm up and when hot the oil is thinner which allows it to travel around mechanical components much faster. Once the oil is thin, the turbocharger is properly lubricated and spooling the turbo will be much safer. After a long drive where the turbo has been spooled up for long periods of time i.e. motorway runs.. it is advised that before turning the engine off, allowing the engine to stay running for 1-2 minutes while the turbo cools & spools down. Shutting off the engine immediately may result in back-spin which is not good at all and can damage seals, bearings and the fins on the turbines.

Remanufactured Turbo for Audi A4 1.9TDi 2.0TDi (DPF Model) 2006What Do We Do
When your turbocharger unit fails, garages & dealerships will advise of having it replaced and most commonly a new unit will be the only choice given to you. The reason for this common choice is you are offered a better warranty on a new unit then you are on second-hand parts. You can purchase a second-hand turbocharger from a breakers / parts shop but the maximum warranty offered will be 30-90 days.

What we do, however, is remanufacture your existing unit & where possible, replace it with an exchange turbocharger off the shelf which has been re-manufactured by us ready to send out. If you send your turbocharger to us here at Sinspeed, we’ll strip your turbo unit down and replace all seals & bearings with new & genuine parts which meet & exceed OE specifications. The compressor housing will be machined and fully leak tested to ensure a rebuild of the highest quality before returning the turbocharger unit to you with a full 1 year warranty. In fact, you won’t even recognise the turbocharger as we chemically clean all units before rebuilding them so they look as good as new!
