This is a follow-up to complaint 10146994 filed on 1-05-06. It concerns the rusted out fuel lines on my 100cs wagon from audi. I have started to tear down to replace the lines, and see where the main issue seems to be. At all of the mounting points for the fuel lines on the underbody from the fuel tank to the engine compartment, the lines have rusted through. There were actually 8 leaks instead of the three that I originally thought were present. Due to the rubber mounts being compressed around the lines, not...

all of them showed the leaks until the mounting brackets were removed. It appears that the rubber mounts that are used hold water etc. Allowing the fuel lines to be prone to rust through in these areas. In checking online forums, it seems to have been a problem with previous model years as well. I have found numerous reports of people replacing rusted fuel lines on audi models. I have not made a big issue of it with audi as of yet, only contacted them to the point that they said they would not replace as a recall. I am surprised that there was no previous action on this as it creates a fuel leak that can be a source of fire. My guess is that if these leaks were in the engine compartment where an easier ignition source could be found, this would have been a big fire issue and recalled. *Nm

Recently purchase a used 1992 audi 100 cs wagon. When I got it home and in the garage, there was a terrible gasoline odor. I noticed the puddle on the floor, and got under the car to check it out. Sure enough, there was gas leaking from the fuel lines in multiple places from the tank to the engine bay. All of the lines are severely rusted, to the point that it has sprung leaks. In checking audi online forums, it seems to be a common problem, with most people splicing in sections of hose to keep their cars...

running without having a persistent gas leak. I was suprised to see that the only fuel line recall on these units was 1993 and 1994 models. Luckily, I caught this thing before their was an ignition source to cause a fire. Currently, I am planning on using the ever popular tube splice until I decide if I will bend myself a new set of lines since replacements seem to be hard to come by. *Nm

1993 Audi 100Fuel system

For several years I have been complaining of an intermittent, very strong fuel smell. Audi has never been able to tell me why this occurs. It has been present transiently and it has been present for prolonged periods of time. The smell, when present, is extremely strong. This is not related to and is entirely different from the "sulfur" smell that is frequently present in the winter. On one occassion, it was present for almost a whole week after the car sat for the preceeding week without being driven. I had...
