Brill, trouble is the Mk1 is a bit on the light side for towing. 85% is only 1222kg What is the point of an anti pollution device that causes more pollution to work properly :rolleyes: If I do go for a Mk2 how much are we talking for a re generation should I need one? Is it a Citroen only job? Is it true this fluid is made from water and urea, if so why so expensive? Makes me feel like getting an old 4x4 and bugger the environment ;)
