Hello, I’m the new one and I’m sure I have to drive an old omega more often than not 🙂 I had a change of oil and the master convinced me, despite my concerns, to a rinsing. Now the hydros clatter and flutter or whatever when starting about 3 minutes long. My question to the master why that would have to be he answered with” is normal with such an old car”. Just stupid that it was not before the change of oil. The old car is a 96 he Omega B 2,0 16V ohn e any tuning etc. What can I do or can I do at all? Invoice for oil changes not available.
