Good morning, I bought a cheap VW Lupo AUC 1.0 for my son. Running power 145000 Year 2001 I have a few questions about this, and hope for help here in the forum. I write under the errors times my further procedure, should someone have improvement here, I am grateful for every tip. Error 1 Engine control light flashes in the stationary gas engine runs restlessly No performance when acceleration error read out P0301 Further procedure spark plugs, as well as ignition control kit renew. Throttle valve was provided with cokes, this I have upgraded and completely cleaned. Error 2 The seller told me that half a year ago the AGR was exchanged. This was done by a Free Workshop. AGR also looks new. Despite all the driving the motor control light permanently illuminates. Error P0404 Further procedure here I am honestly quite standing at a new AGR on the hose. Can the error P0404 AGR from the first error be caused by false exhaust emissions values?
