Each time I turn on the engine it says Depollution System Faulty, the diagnosis says "P1461 | Exhaust Gas Recycling Electric Valve Copy Signal Valve Low Limit Drift Since First Start - up ..."
I Have no idea what this error means, all I know is that the EGR has a problem. Could someone explain what this error is trying to say?
Is it blocked? Should I try EGR cleaner something like this
Peugeot 407, 2007.
Also done two trips on the motorway (32 miles motorway one way, so about 128 miles) and it didn't turn off so it's not the DPF I believe.
Story: Received it from the mechanic like this he said after it goes on the motorway it will be fine. There is no loss of power nor any signs of any issues from the error at the moment.
I thought it may be clogged up and really considered using the EGR cleaner from the link above due to the 57/62 reviews all saying it did well. However, I realised I don't actually understand what is even wrong with the EGR imho the error is unreadable?
