In December I had a valve spring break on my Omega Sport 3.0v6 24V. The ZKD was replaced with ZKD, planned with ZK and everything around it. But now my car is steaming more and more and I have had to refill 4x water in 3 months already. So I got the car back to the workshop yesterday, with the statement that they should check if they have mounted the ZKD correctly. Now they have disassembled everything and say that the ZKD is But they would have been told that it could be the water-cooled AGR valve. Has anyone ever heard of the AGR being water-cooled? Or that is being burned with a defective AGR water? It seems to me a little Spanish. But it has to be cleared in the workshop and that tomorrow morning. So it’s urgent to help!!!!! Mfg
