A6 2.5 TDi AFB Won't Start

[philfingers]

Ok I checked the lift pump, it's drawing 4A. Pulled the back seat up but it seemed loudest when I was listening in the OSR arch. Pulled the connections off the fuel filter and it took about 1/3 of a filter's worth of diesel before it was full. I then cracked the injectors (each bank seperately) and diesel was coming out when i turned it over. But wouldn't start? Should the diesel come out if the system was immobilised? Also the lift pump didn't pump any fuel out of the filter unions when they were off as Adamss24 had mentioned. Bit odd it's got a pump tho being a 1999 car.

I got an OBD /USb today and with 409.1 I got the following message

Address 01: Engine
Controller: 4B0 907 401 P2
Component: 2.5l/4VT EDC 0000AG D60
Coding: 01001
Shop #: WSC 02325
1 Fault Found:
17978 - Engine Start Blocked by Immobilizer
P1570 - 35-00 - -

BUT i cleared the code and then tried to restart it several times and no code was then reported.

Any ideas folks?
