Hi all,
Usually I don't really open new threads as I like to search and search I really appreciate this form for the information that i find tips and etc and the helpful people that sign in every day to help each other and share experiences.
This time I am stuck and seeking your help.
Iâm suffering from the occasional over boost and "Limp Mode" this has happened before the remapping and after the remapping. I'm afraid of putting my foot down now because of going to limp mode and finding a place to pull over to switch off my car and start up again.
Before taking my turbo off and giving it an hour clean which is not a problem but the hard bit is taking the turbo out which is a nightmare for me, where do i look else? boost pipes? recently replaced the inter cooler pipes left right because of joint split i have checked them they OK for now also the pipe that connects to throttle body used to leak air but now i have tighten it with jubilee clips.
Thanks and your help is much appreciated
