Hello,I drive a 406 Break 2,2 ltr,Machine,Bj,2000.I have now at 120000,km the timing belt water pump and everything that is about to change.My now at 2000 u/m makes a roaring vibrating noise,the workshop has blown everything for the 2 times,because it is there the set is not okay.The noise is still there,the workshop has asked at Peugeot directly,which are of the opinion that the adjustable camshaft(gear adjustable?) of the Urherber could be,but s they are not, the master thinks it is the tensioning role below where the belt runs over, which he has just played there.Perhaps one of you has an answer,or similar problems ? Can it lie on the camshaft ?? Thanks in advance. Martina
