Hi

We have a Audi A4 1.9l TDI s-line estate

It has the DPF light on - Engine management light on - Glow plug light on - also i think it in limp home mode - the car will not rev above 3000rpm.
We read the fault codes and it said 08194 particulate trap back 1 : efficiency below threshold : P2002 short with power.
We have fitted a new DPF filter and the engine management light has gone out, but the DPF & glow plug light is still on and will not clear down.
The DPF filter is a new one from Audi.

Thanks for your time.
