So - latest drama, TD4 blew a hole in the EGR coolant hose when 100m from home ! I have an EGR bypass and a kindly AA man had enough pipe to make a temp fix - however, can I bypass the coolant pipes as I don't use the EGR anyway - that would simplify the pipework, but is the coolant through the EGR doing anything else useful??
Also, after the temp repair, the car ran rough and sounded like it was in too high a gear with mechanical vibration through the car for about 20 miles, it then cleared and now seems fine - WTF was this all about??
Is it because the coolant got lost from the auto box cooler, the IRD cooler and all was not well with the oil temperature?? Has anyone else had this problem, basically that loosing coolant and a mild overheat has affected what appears to the transmission??
Root cause of failure seems to be a slight diesel leak from the turbo pipes which has rotted out the coolant pipe - it has gone all soft and stretchy - others beware !
