Now getting code P0442 which shows as an evap leak. Research shows: Motronic ME 7.1.1 - LH P0442 ANTI-EVAPORATION CONTROL SYSTEM No pressure increase measured within the fuel tank. (Major leakage)The error can be validated only while running the anti-evaporation test. Tank leakage Checkout of possible losses within anti-evaporation circuit. Check of fuel pressure sensor. Check of solenoid valve cable. ...also smelled fuel in the garage after the last time I parked it. Here is what I found on the system and how it works: The vapours coming from the tanks are carried, through the ventilation valves provided for this purpose, to a separator. From the separator, the vapours enter the active carbon filter, which absorbs and retains them. With the engine running and depending upon the operating conditions, the Motronic ECUs control the canister purge solenoid valves ( C 3.08) so that the fuel vapours retained by the carbon filter are drawn in by the intake manifolds through the specific lines. The air from the compartment enters the active carbon filter through an air pump ( C 3.07), controlled by the engine ECU. Before the pump there is a filter that prevents foreign matter from entering the system. The diagnosis pump cyclically pressurises the entire anti-evaporation system, in order to detect any possible leaks. Guess I'm wondering what basic troubleshooting I can do before putting it on a truck to the closest Ferrari dealer 3 hours away. Check all lines on evap system? Smoke test it? Sounds like the pump pressurized the system and it did not read a rise in pressure - hence a leak and the code. The shop had the intake manifold off to fix a leak in the heat exchanger. They also had the valve covers off to replace the valve cover gaskets. For the former I believe all, or many of the evap lines have to be removed/replaced. Seems odd that it would take 1k miles to show up though if it was something they put wrong in the last service. Anyway, any advice, let me know - looking through shop manual and this site now.
