Continental GT Speed air suspension issues-Help?

[vet652000]

Had slow leak on right front strut, replaced both front struts, and it still has a very slow leak on front. Checked for leaks everywhere, found nothing on struts nor valve block, ran tests on level control with VCDS- sequential test said-OK and reservoir pressure was 16.24 BAR. Ran all the options in basic settings, one at a time, and all worked no problem. Said my heights were not saved even tho I did that a month ago, so I redid the adaption, gave me some grief on the #4 right rear setting, if I entered the actual height which was off by 4mm, it would say invalid and I had to start over, I tried 6 times, same result, so 7th time I just used the default number and saved, then entered 1 on #5 and save and it confirmed calibration. So after all that here is were I'm at - still will leak down in front over 12-24 hrs, rear seems to hold. I have a valve block I ordered, anything else I should do before I change the valve block??? When changing valve block can I just use the basic settings and empty res, and then front, and the rear until system is 1.95 bar which is atmospheric pressure, then unplug valve block, unhook lines, unbolt bracket, swap bracket to new valve block, reinstall, hookup lines, plug in. Then start car or should I do something in VCDS to activate level control? I really need to put this air suspension issue to bed, so I can do 40k maintenance, plugs/coil packs/ egt circuit boards/ cover gaskets and seals, etc

Dropped 1/2" in front over 12 hours, rear is holding. Valve block coming today, do I change or any other ideas?

Hi vet,
I have a friend who is chasing this same problem down. I see there has not been any response to your query.
Are there any other useful hands on sites for the Bentley Continental you use that give advice for hands on guys?

There's a couple of good Conti DIY groups on Facebook.
