After 17,000 kM with the first one, after a further 14,000 kM, the second AGR valve was changed. At times, the Croma no longer took any gas, if you were lucky, it started with a little delay. In addition, there was a significant loss of power in the lower speed range. This problem is not unknown to the workshops and thus a new AGR valve was ordered directly. However, these are in a backlog with Fiat and you have to use a Until then, my workshop has closed the AGR valve with a sealing disc. The Croma runs as usual again, only the engine control complains now. I will also have the charging pressure sensor cleaned and talk to the workshop again about the retrofitting of the “hole plates”, which are probably offered by Fiat and should limit the exhaust gas return quantity. However, my master said, the AGR valves would have been revised and the new versions would no longer need these plates. So the arduous topic of the AGR valves with the diesels does not end. Let’s see if there really is a revised version and if it is better. Greeting Balu
