glow plug location

[philc.]

hi, i have a3 tdi 2ltr sport 140, engine managment light has come on, had it on a diagnostics telling me one of my glow plugs is failing, though it starts and runs fine, anyway going to change them. where are they located, clearly they are not obvious. :1zhelp:

thanks

Take the cam cover off, they're next to each injector.
