Thanks ML

read the post and what should i do, replacew thew sensor with a new one,anuprated one (if you can) or a blanking plug (what size and thread)??

Is this related to the Left bank lean error code too? on a full decat?

People have removed the EGT sensor as it is not 100% necessary and if it fails then it ends up in the turbo. "Gussy" on here has done this and also made a resistor fix !!

It might also be that the EGT's are high and this is being flagged up by the ECU.... I have a TD05 variant turbo which produces higher EGT's and my mapper (Bob Rawle) raised the threshold at which the ECU thinks the temps are too high.

Lean AFR's = higher EGT's so you may have a fuelling problem ?? I'd have the car thoroghly examined particularly if modded and mapped !! Delta dash / AFR's and det cans spring to mind but maybe someone has had this problem before and will post
