Hi Lofty,just registered with the site to thank you. I have had the limp mode problem with my mk.1 Octavia since just after I got it at the back end of last year (maybe all the time I have had it?),so I googled it and found your post on the forum. We already had some Mr.Muscle under the sink (result!) so I got some pipe and an elbow from Pets at Home and got on with it. Everything came apart easily after I soaked the turbo end studs for the EGR overnight with WD40. After spraying in the foam I tried to work the actuator it didn't seem to move much so I left it for a while to let the foam work its magic. It still didn't move much,thats when I wondered if the actuator was stuck in the down end of the stroke so I levered it up with a screwdriver and sure enough it sprung back up (worth remembering if anyone else is trying the job).I carried on working it till it was free then put it back together and gave it a test run, as many other people have found,I now have a completely different car. To anyone thinking of trying the fix I would say go for it,you wouldn't beliveve how easy it is! Thanks again Lofty
