To cut a long story short, they checked all the wiring 3 times and replaced the fuel pump relay. The car lasted 20 miles before the light came back on. After checking the wiring again (back on again) they admitted defeat and told me to take it to a diagnostics specialist.
This came up with the same code and the advice to check the wiring, relay and ECU in that order. As the rest had been checked I bit the bullet and forked out £955 on a new ECU. 40 miles later, guess what. Same code. Also in the backgroung are the codes P00CC and p00C8, although not frequent. Anyone got any other ideas?
