Hello, since I have a Omega B 2.0 16V incl. climate; motor X20XEV, I noticed very much that this has been a cooling water loss for days. It is so that in 2 days it has to fill a half liter of water after, but it is also funny, because I don’t find the error. I drove by car 50 kilometers, arrived at home on the ramp and waited, nothing, no leak or anything else. This twice, because I also drove with the climate and once without. If you have any idea where this comes from, I also have a problem, because my omega makes such grinding noises when driving, but as soon as you press on the clutch, it is gone, you let them come back again (coupling) the grinding is present again. I did the following. Gear oil change, incl. rinse, while I let off the old, new in, driven a hundred kilometers, gear oil out again, new Is it a little bit quieter, but not away. Do you have a tip? Thanks in advance. Andy
