Got a vw bora. Its the 1.9tdi version that has been chipped to 150bhp. It is now losing water and over heating at anything over 70 on the flats and if you try to go up hill it starts to over heat like a bitch. Also the heating seems to be going on it to. Like it will just randomly go cold for no reason.
I know a wee bit about cars but not that much so any help will be useful.
