Daz1986 Posted September 16, 2021 Report Share Posted September 16, 2021 (edited) Anyone know what this is guys!! Got air leaking from it!! Think it’s causing my discovery 4 to go to restricted performance.. I think it’s a bypass valve! Would this cause my issue as seems a small leak Edited September 16, 2021 by Daz1986 Quote Link to comment Share on other sites More sharing options...
Hector Vector Posted September 17, 2021 Report Share Posted September 17, 2021 You really need to get the fault codes read as a start. Restricted performance can be caused by many things. Then armed with that info get on over to DISCO3.CO.UK. You'll get good advice there, not a slating for owning a Land Rover product! Quote Link to comment Share on other sites More sharing options...
ditchman Posted September 17, 2021 Report Share Posted September 17, 2021 (edited) would help if you could put up a better photo.....is that a linkage bar i see.....what is it attatched to ? the turbo ? is it the boost control ?...(actuator).if it is the actuator it is a very easy fix and would account for the poor performance Edited September 17, 2021 by ditchman Quote Link to comment Share on other sites More sharing options...
Daz1986 Posted September 21, 2021 Author Report Share Posted September 21, 2021 I am no mechanic. It’s a small bit that is down by the EGR pipes Quote Link to comment Share on other sites More sharing options...
