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.
On a side note, when the DPF get’s blocked it’s a very expensive repair. However, Sinspeed does offer a very affordable & competitive DPF Removal Service.
Common Symptoms of a Failed Turbocharger
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!
The Audi A4 1.9 & 2.0 TDi (DPF Model) turbo charger failures commonly have damaged fins or snapped turbine shafts. We can still remanufacture these units because we have access to all brand new & genuine parts.
