Hello everyone,
I own a PFL for pretty much a year now and the RS3 adventure is becoming a nightmare since yesterday.
I was sitting in the car yesterday using VCDS and testing a few diagnostic softwares, and left the car idling for a long moment, probably 30 minutes +.
I started progressively smelling fuel outside the car and discovered a leak behind the right hand tyre.
The panic was real and I instantly shut off the engine. Not even understanding why I pulled the tank cap, hearing a big pressure release that progressively stopped the fuel leak.
The leaking area I identified is basically the active charcoal container or right behind it.
I brought a mechanic to my place and started the car again, but we couldn't reproduce the leak.
Today I started the car I went for a very quick drive around my neighborhood :
- driveability is atrocious, obvious loss of power, under regular load sometimes the car is jerky and I can clearly feel power cuts as engine RPM goes down then back up while the throttle is applied
- idle feels super weird and not very regular, monitored it through vcds and discovered that I was going from low 700 (710) to almost 800 RPM at idle.
- car can be left idling and engine shuts off by itself (happened twice)
VCDS and other softs scan brings no error regarding engine/fuel system issues.
What do you guys suspect ?
Active charcoal container ? Fuel pump ? Fuel pressure regulator ? Purge valve ?
Few additional data :
Nothing under the hood, no leak and no fuel smell on the oil dipstick.
Car is stock, only a few mods like secondary decats, nothing serious.
Service less than 3000km ago, including new spark plugs.
I live in a country where Audi don't even sell Petro A3s, let alone RS models. (all replacement items have to be ordered, it took them a month to bring 5 spark plugs)
I just want to know what I'm up against before taking it there.
Thanks for reading.
