To have an ending to this topic, I have got the car approved after replacing few parts: bushings I used Powerflex, they are very very easy to install. I have alo Meyle but these are very difficult to install so I gave up and used Powerflex.
Then I replaced camshaft sensor, lbda, I have cleaned the El contacts and no more error shown. Also a full service, oil, filters, spark plugs.
Doing all these got the car approved with naf.
