Ebay it or remove unit & repair, could drill into each end, fit a pin, smaller rod, threaded screw with head cut of, inside both ends with 2 pack resin or superglue, make sure the ends break lines line up, leave for a day, refit & test.
Even if the fuel pump fuse had blown, that doesn't stop the dash from lighting up I'm afraid & the car starts, but immo forces a shutdown, so pump is probably ok, although could be residual fuel in the lines, unlikely imho.
I'll be honest, I got it foc as I know the master tech at my dealer guys due to business etc :)
But all comes down to hourly charges with audi, a leak test would be 30 mins to 1 hour max, if that as a leak should be very apparent in 5 minutes flat.
Ye man I can appreciate that, CT can be very deceitful huh, on a day where its windy as hell you can get sunburnt in 5 minutes flat, then again that maybe due to all the castle we sunk on that day which transpires 5 minutes when ****** but several hours when sober lol
