Very slow, from max to min on the expansion tank in around 1600 miles. Recently replaced the cap with an original Renault one to no avail.

Pressure tested the system with no drop or signs of leaks but the expansion tank cap doesn't bottom out as such, you can over tighten it to the point it goes slack again, like the previous one did. Could this be a sign it's the expansion tank itself that'd dodgy?
