Yeah, they were yellow. Is the yellow one "subpar" to the green one? I didn't replace them yesterday though since I didn't have the parts. Planning to go to the Jag dealer on Friday and get them and install them on Saturday.

 

Yes the green are the new improved variety, they are I believe, a little fatter and have a sealant built in.

 

Cool...I shall look out for that when I go to the dealer on Friday. Thanks.

 

I just changed the o-rings today. Thanks for all your help guys. Really appreciated it.

 

Well done.

 

Congrats Sal!!

The big question though.
I take it you cleared the codes after you replaced the yellow orings to the new improved green orings. Are your codes cleared from the OP (original post)?

 

Yeah, the mechanic at Midas cleared all the codes when I asked him to diagnose the problem.
