Audi Fuel System Problems

Audi is recalling over 1,000 vehicles because of quick connectors that are supposed to hold fuel supply lines in place aren't doing their job.

The detached lines will stop supplying fuel to the crankshaft and start depositing it onto hot engine surfaces. When flammable liquid meets something as hot as an exhaust manifold, things happen. Things you don’t want.…

A couple years ago the 2007-2012 Q7 and 2009-2012 Q5 were recalled to fix leaking fuel pump flanges.

At the time, there weren't enough replacement flanges to go around. In a let's-see-if-this-works move Audi slapped some butyl tape around the existing flanges to prevent future leaks. It didn't.

Turns out if the flange has already been exposed to outside contaminates, covering it in tape will only prolong the inevitable leak. About 6,000 vehicles are being recalled again, hopefully this time for a more permanent repair.…

One way VW and Audi can win back the good graces of US consumers is through their favorite vehicle, the crossover SUV.

But they're not going to win many fans if those crossovers keep catching on fire due to a fuel pump defect.

"... Audi is expanding a previous recall involving 2013-2017 Audi Q5 and 2013-2017 Audi Q7 vehicles with fuel pump flanges that can leak gas, leading to the possibility of fires. More than 240,000 vehicles are part of the recall"…

The suction pumps inside of Audi gas tanks aren't doing their job and could prevent owners from refueling. Well, that sucks.

"The problem occurred during manufacturing when seal rings inside the suction pumps were assembled with too much force, damaging the seals that could then allow fuel to leak into the evaporative emissions systems. VW says a driver may notice problems when putting gas in the vehicle, namely fuel nozzles that stop while refueling or fuel that flows back out of the car."…

Back in 2015, owners started complaining to Audi that they were smelling gas inside their cars.

Not much was done about it, maybe just a thank you for your concern and some pre-canned response about how we value you as a customer, yadda yadda. But then...

"The automaker found small cracks in the fuel pump flanges but couldn't determine the root cause, but engineers found that adding butyl rubber bands fixed the problem."…

The hoses that carry fuel throughout your car are degrading, falling apart, and started to dump fuel instead of carry it.

"Audi saw an increase in warranty claims related to leaking fuel hoses and the automaker opened an investigation, finding the hoses showed an abnormal aging due to the porous structures of the hoses. Engineers at first couldn't duplicate the problem, but then they determined hose damage mostly occurs by restarting the engine."…

Federal investigators couldn't figure out why perfectly good fuel pumps were failing in some Volkswagen (and Audi) vehicles.

The investigation lasted 4 years and had VW's full cooperation.

The pumps seemed fine and even came with built-in margins for fuels that were slightly out of specification. What the pumps couldn't handle is owners filling up their diesel engines with gasoline.…

Manufacturers can sometimes drag their feet when it comes to issuing recalls.

But whenever there's reports of fuel leaking out of cars they start to move like someone lit a fire under their butt. That's because, well ... there might actually be real fires soon.…
