Hi im fairly new to this site and need your help!! Ive got a mk 2 seat leon fr plus 2.0 tdi cr (170) recently had the cambelt and waterpump changed. Im having issues with the heaters! Car runs fine, gets up to normal temp on the gauge 90 degrees or there abouts. Heaters work fine untill after a long ish run and then they blow cool from temps 24,25,26 ( car has climate control)but are then hot on the highest setting only! This happens quite often and is getting frustrating. Have you any ideas? Or had the same issues please help!!☹☹
