My A4 170PS went into limp mode with a flashing coil light, EML and DPF symbol.
DPF Symbol came on first but after no joy with a regen (usual motorway driving in 4th/5th above 2k revs) the coil light and EML then came on.
Going by the above I believed it to be a faulty DPF Sensor.
Disconnected the sensor cleaned the pipe and electrical connections, reconnected and the DPF light along with flashing coil has cleared (still have the EML which I beleive VCDS is needed to clear).
The car drives as normal (took it a 45mins motorway drive), my question is can it be as simple as cleaning the DPF sensor or will this go into fault again ?
What's peoples experiences ???
