You dont technically need the heater on hot to bleed the system the matrix is always flowing with water even with the heater control dial set to cold, some earlier VW's had a regulation valve (ie Mk1 golf) which stopped coolant flow through the matrix when the control dial was set to cold but not the Corrado... You are a knowledgable chap i must say lol. I never knew that. Quote Share this post Link to post Share on other sites
