Why dont you give your local VAG a ring and ask them. They'll probably charge you tho.

looking on the web this looks likely

"17978 engine control module blocked by immobilizer 35 - 00--"

you need to run a diag on the immobilizer, to see what is wrong there

Your right, it is to do with a immobirlizer fault, but the garage bloke said not to worry about it, has the car starts okay.

just out of interest, which site did you look at to get the descriptions for the fault codes??
