Had the coil light flash up this morning and about 5 seconds later total loss of power and no restart recovery agent plugged in the diagnostics and got code p0087 , now it’s been recovered home what am I looking for in VCDS to try and pin point the cause of this ?
Cheers

Fuel pressure, supply issue on quick search, check lift pumps under rear seats, when ignition is turned on they should pressure up immediately, with seat base lifted you should be able to hear & as its a quattro there will be 1 either side of the prop, under both rear seats usually.

Check relays, fuses.

All fuses / relays checked removed rear seat base pump isn’t that loud , could the lift put fail enough to not provide enough pressure but still pump ?
