Replacing O ring in turbo to pressure hose (drivers side)

[PKN]

...This should be easier than it looks. I have removed the pressure hose from the turbo (cylinders 5-8) and noticed that the aluminum casting between the pressure hose and the turbo has some play so while I was doing the job I thought I would replace the rubber O ring at this joint.

Unfortunately, the casting has a short rubber hose attached going to what looks like a vacuum control pod and there is not enough movement in the hose to pull off the casting to get to the rubber O ring. I loosened the clamp at the vacuum switch but the hose but it wont pull off and I don't want to break the plastic fitting. Is the only answer to cut the hose and then replace it?

All advice gratefully received

I did a DIY. Maybe this might helped. You have to wiggle it. I had enough room b/c my air filter box was replaced with cold air systems. I recommend you to remove your air box.

If you search in Rennlist.com. "DIY 05 CTT Pressure-Pipe O-ring removal" here you will find the info. Sorry couldn't figure out the link.

Many thanks - I found it. The rubber hose is still not prepared to budge so I will cut it off and replace it as the easy solution. Parts arrive tomorrow and hopefully I will be driving her again this weekend
