Anyone know if audi have changed the temp sensor on the tqs ordered one and its dark green prt no is 059 919 501 where as mine is blue iirc do i need the blue one ?? Only asking as the outlet on the cyclinder head is leaking coolant slightly so thought id get a new sensor whilst im at it also would you recommend fitting a non-gen oil cooler or is it best to fit a genuine ??? Cheers in advance.
