Thumbs up Audi A3, 1.8, Code AGN.

Customers complaint, idle up down, power poor,

One DTC in the system P1508, (17916), set = idle system learned value upper limit attained.
The idle was up down and car poor to acc: up at times, it was noted that there was no fuel return.
On fitting a pressure gauge the pressure was only 1 bar, this gave code P1508 as the motor was to lean, fault was pump in tank.
