Goodaye guys ( and girls?) Is it possible blocking the EGR results in varying temp gauge readouts? I've had my td42ti for two years. Have done a trip to cape york in may/june and several trips around Vic at all times of the year. The pipe on my EGR broke five weeks ago and the mechanic blocked it of as we were leaving for Central Australia the next day. During this trip I have found the temp starting to rise on long hills and in the hot conditions in the Centre go up to 3/4 when driving into a head wind or sitting on 110 k's. It has never been over half before. Could this be related. Does the turbo run hotter with the EGR blocked and deliver hotter coolant back into the engine? Any thoughts?
