hi guys n girls. having a few niggles with my 1.9 tdi 2001,only had it a few months so its still under warrenty, car can be fine for days but every so often it seems to be limited for power stuck @ 2000 rpm, have took it back and they cant find a prob, i.e it didnt do it for them, they have changed the MAF sensor, next day noticed intermitant hot air through blowers, next time i take it out my tempeture light came on, checked water and yes it was low, topped up and that was two days ago, went out again 150 miles no problem up hills and down, now my partners texted me saying the temp light is on, any help so i can ask the garage
