Audi Q3 fuel pump replacement. This car was towed to the shop in Crank But No Start Condition. First things first we checked the fuel line and it was filled with air. We immediately shifted our focus towards the fuel pump submerged in the tank. Guess what? No fuel in the tank. Absolutely bone-dry. Engine fired up instantly after we filled some fuel. So what really happened here? The car owner was misled by an inaccurate fuel level. The sending unit in the fuel pump failed throwing erratic fuel level readings. These units run on a potentiometer or variable resistor whose resistance changes on fuel level. Over time, the contacts in the resistor can wear, leading to an open circuit. The fuel gauge might interpret voltage feedback from a dead sender as full or empty regardless of the actual fuel level. . . . . #audi #q3 #tdi #vagcars #german #diesel #fuelpump #fuelsender #manandmachine #autoshop #autorepair #autodiagnosis #accuratediagnosis #oeparts #mechanical #automotive #electrical #garagediaries #shoplife (at Madhapur) https://www.instagram.com/p/Bxcdp__pc62/?utm_source=ig_tumblr_share&igshid=n8z2v79gfqp1

Skoda Superb fuel pump module replacement. The sending unit in the old pump failed throwing erratic fuel level readings. These units run on a potentiometer or variable resistor whose resistance changes on fuel level. Over time, the contacts in the resistor can wear, leading to an open circuit. The fuel gauge might interpret voltage feedback from a dead sender as full or empty oblivious to the actual fuel level. . . . . #skoda #superb #tsi #vagcars #fuelpump #fuelsender #fuelgauge #manandmachine #continental #autorepair #autodiagnosis #germancars #automotive #garagediaries #shoplife (at Hyderabad) https://www.instagram.com/p/Bu20VyDAzS_/?utm_source=ig_tumblr_share&igshid=t4goquz2me81
