    Hey guys - looking for some advice.

    I recently had my '05 430 F1 coupe serviced. At that service, all of the fluids were replaced. No leaks were noted last year or prior to the service this year (car was driven once for a short period prior to service).

    After receiving the car back, I have noticed a small puddle of red fluid develop on the garage floor just inside the passenger rear tire. It accumulates immediately after a drive. After the floor is wiped, the puddle does not re-accumulate in between drives. I've driven the car 3 times since service, all three times the red fluid leak has appeared.

    I did not check the level in the F1 reservoir initially, upon receiving the car back from service. Upon checking the reservoir after the 3rd drive (making sure to completely prime the system), the fluid in the reservoir barely touches the end of the dipstick.

    Visual inspection of the F1 components through the access panel does not demonstrate an obvious source. However, upon inspection of the under tray from above (through the engine compartment), the end of this "?vent hose" appears wet and potentially the source of the fluid.

    What does the hose in the attachment, which is zip tied along the passenger back side of the engine bay, vent? Is it related to the F1 system? Trying to figure out if this is a potential source or a red herring.

    Thanks for any and all input.

    Almost certain that the F1 reservoir got over filled. Someone probably used the dipstick as an indication of how much to put in. Logic supports that idea but this is after all a Ferrari, a self propelled logic free zone.

    My Scud had the same problem after service. I was concerned and called the dealer and they said it is supposedly very hard to get the F1 fluid correct so it usually get overfilled and pukes out the excess. My suggestion: Drive the car several times and put some paper under it when parking and monitor. Most likely your problem will go away!

    That hose is connected to the top of the reservoir

    I appreciate all of the input.

    The diameter of the hose in the picture is significantly larger than the vent hose exiting the reservoir cap. I assume that the smaller diameter reservoir hose is somehow mated to the larger one shown (back behind the F1 components out of sight)?

    In the spirit of diagnosis, does anyone see a problem with placing a vented catch can/bottle at the end of the larger hose to confirm the source?

    Thanks again,

    Jason

    Correct. I only know this because my f1 hydro hoses went bad and I thought the leak source was that drain hose. If you take off the rear defuser you can see it clearly.

    You want to check the level after the car has sit quietly overnight. Leave the engine bonnet open over night and do not open any doors or the ignition. It should be cold and completely leaked down off of pressure overnight.

    Check the reservoir with a clean small stick, like a plastic toothpick or detail cleaner swab. The fluid level should be 5 mm above the flat plate in the reservoir. That's isn't much, but that's what it calls for.

    At least this is the method I was taught by several experienced Ferrari technicians.
