2008 Volkswagen R32 fuel system problems

Filed Apr 3, 2024 · Electrical, Fuel system · CA

My vehicle started to develop a crank no start and intermittent stumble when idling at a light shortly after starting. I chalked it up to a possible fueling issue since I had lean codes. I replaced the fuel pump and filter with OE supplier parts. Within two months the crank no start situation returned. I began to research the concern and buried in a forum someone mentioned checking fuse 43 in the underhood fuse box. I went out to my car, removed the fuse and found that there was arcing on one of the legs and extending upwards into the fuse itself. I researched what the fuse is for on the VW service information page and it supplies power to the ignition coils. When I got home I removed the fuse box, opened it and found that the terminals for that fuse were slightly opened when compared to the rest of the box. I have not taken my car to any shop since as I was a certified VW tech and have the appropriate tools, education and training to work on my car. I have attached pictures of the fuse and the interior of the fusebox that shows the slight spread on the terminals. This thread covers what was happening to my car almost exactly, post 27 is where I learned about that fuse.

I exited from a driveway at a riteaid to get to the light across the street, I have about 3/4 tank of gas and the odometer reads 175 miles, when I get to the my next destination, a drive thru, the fuel marker starts dropping fast and so does my odometer, it goes down to above 1/4 of a tank and my miles read 110 left, in a span of about 10-15 minutes. The vehicle was stationary in the drive thru except when moving

When certain driving conditions are accompanied by high ambient temperatures, the fuel tank ventilation valve may not remain fully closed. If this happens, liquid fuel may enter the fuel tank venting system and migrate into the evaporative system, saturating the carbon canister. Should this occur while driving, the vehicle may experience performance issues (I.e., vehicle jerking) and the malfunction indicator lamp (mil) in the instrument cluster could illuminate. Fuel could leak from the evaporative system leak detection pump filter. Consequence a fuel leak, in the presence of an ignition source, could lead to a vehicle fire.

Raw fuel spewing from leak detection pump (ldp) filter located under passenger side fender well. Charcoal canister, ldp, evap lines, & n80 valve all contaminated by raw fuel. Fuel entering evap system when high ambient temps are present. P026 recall was already performed (in 2012) but issue has come back. Contacted vwoa they said it's beyond the recall's 1 year 12,000 mile extended warranty and that they would not do anything to fix the issue. This is a fire hazard that could potentially lead to serious injury and/or death. Because vw knows about this issue they should be held accountable. Vehicle was driving in normal city traffic when I smelled raw fuel. Pulled over to see fuel spilling out of rear passenger fender well.

1) purchased the car and noticed the jumps twice on my way home. It has since continued to be an issue for the whole two weeks of my ownership. 2) accelerating from a full stop the car hesitates, hangs, and then jumps forward after a moment. This happens about half the time. I notice when I roll slowly ~5 MPH it does not hang or jump nearly as much or as often. 3) nothing has been done as of yet. I plan to take my 2008 vw r32 to the dealership to see what may be the cause.

Tl*the contact owns a 2008 volkswagen r32. The contact stated that the vehicle was stalling and he smelled gasoline. He was able to restart the vehicle after allowing it to cool down for a couple of hours. The vehicle operates normally for a few weeks before the failure recurs. The vehicle was taken to the dealer, but they could not remedy the failure. The vehicle stalled once again. The dealer stated that the VIN was not included in the federal safety agency campaign id number 09v093000 (fuel system, gasoline:storage:tank assembly), although the failures were identical. The contact does not know if the vehicle will be repaired. The failure mileage was 9,000 and current mileage was 11,000.

The car loses power (I.e. Hiccups or hesitates) at highway speeds, most noticeable on even the slightest acceleration - even with cruise control on. At times it will idle in a similar staggered way. When city driving the same problem occurs on acceleration. It happens randomly but once it starts, it persists until the car has been shut off and cools down.

Tl*the contact owns a 2008 volkswagen r32. The contact stated that the vehicle would jerk and the gas tank ventilation valve allowed gasoline to escape from the gas tank. The malfunction indicator lamp on the instrument panel would illuminate and fuel would leak from the evaporative system.

No event lead up to failure. The car sputters, hiccups, what ever you want to call it. It has stalled in traffic, and had to be pushed out of the intersection, it would not start back up and smelled of fuel. On numerous occasions it will not start. It cuts out around corners, and has done it with the vw service manager in the car.

This "hiccup" just started happening to me. I took the r32 on a road trip from miami up to northern florida (500 miles north of miami), and 30 miles into the trip this happened. We had just topped off the tank with 93 (girlfriend assured me she didn't fill it up with 87) so this couldnt have been the issue. I was driving at roughly 3,000 RPM's when the car would hiccup all on its own... ? I didn't even need to give it gas for this to happen. I have 14,000 miles on the car, and it got worse throughout the trip. The car even shut off on me 2 times while sitting at a traffic light. I'm scared that the car will shut off on me while on the highway which is a big threat to my life! Has anyone noticed this get worse when your tank is at full? I haven't had this happen to me again the 1 day I've been back in miami. I read some reply's on this topic and looks like vw has no official fix yet? What's the diagnosis? Bad fuel bump???
