water in diesel

Hi guys,
I have a 1994 classic with the bmw tdi lump. I lent it to a "good" friend for an afternoon, and he decided to return the favour by filling her up with diesel. Well, to start with it was red diesel from a farm, and to make matters worse it was mixed with water. My question is this:
Do i kill him?
After draining the tank and replacing with clean derv, she still wont start, has anybody any ideas please.
I will be buggered if i will pay garage prices and would prefer to have a go myself.
thanks one and all, and what a great forum, i have learned a great deal.

Agricultural red diesel contains all sorts of crap including loads of sediment (its really only good for running dumper trucks and the like), its possible you could have a blocked filter and/or fuel lines, did you bleed the fuel system properly after you refilled the tank? does the in tank pump work?

A year or so ago, i had a defender Td5 come in on a truck with a non start problem, the tank was half full of red and about 2 inches of sediment was also in the bottom of the tank!!! It blocked the fuel lines & filter and killed the fuel pump in the tank.

Oh, yes you kill him!!!

thanks Clutchdust, thank god they have the internet in prisons so i could reply from my cell. got hold of him yesterday.
Thankfully I got hold of an old vax machine to suck everything out. Am taking a day off work today to change all filters etc and see if she will fire up. Will keep you posted.
