Hi - got into my 2014 595 Comp this morning to give it some beans on the first dry, clean roads we've had fpor a while here, and encountered this problem.

The boost gauge moves about a bit but won't really go past the first marker, power is cut, like hitting a rev limiter, at 3800 rpm and the engine management light is on. In neutral and stationary, foot off clutch the engine reves as normal, but still no boost.

Any ideas anyone?

    Our 64 plate Turismo showed the same symptoms, new lambda sensors got it running as new again.

    Interesting - what are lambda probes if I may ask?  The car is booked in with Rockingham for a  week today.

    My 595 is at Rockingham today for diagnosis and repair. I will report back as to what the problem (and solution) was along with the damage to my wallet...

    The Lambda O2 sensor is mounted in the exhaust manifold to monitor how much unburned oxygen is in the exhaust as the exhaust exits the engine. Monitoring oxygen levels in the exhaust is a way of gauging the fuel mixture. It tells the computer if the fuel mixture is burning rich (less oxygen) or lean (more oxygen).

    Thanks!

    I have an update from Rockingham.

    A mouse has been nesting in my airbox. It has taken a load of peanuts (from a sack in my garage, put there to fill the bird feeders) and a load of 'nesting material' and moved in. Heavens knows how many miles it has done with me!

    Unfortunately, it has also eaten half of the wiring loom underneath the airbox and this may be the cause of the problem I have had. I won;t know until tomorrow when they replace the wiring and then run further tests, but hopefully this is all that is wrong. £288 inc VAT so far...

    Rockingham took some photos so I will ask them to email them to me and will post them here for sh*ts and giggles :)

    Amazing isn't it?  I bet that doesn't show up on the diagnostics :)

    Rockingham called me this morning and told me the car has now tested OK and the only problem was the mouse damage. I guess chewing through the wiring was the main cause rather than stashing a ton of peanuts in the airbox.

    I'll see if I can get the pics when I collect the car tomorrow morning.

    As my car isn't used sometimes for days at a time, I may start leaving it in the garage with the bonnet open, to try to deter Mr Mouse from starting all over again. Can't put traps down because of my dog.

    Of all the problems I have had with cars over the years, this is the most unusual!

    BTW, I got excellent service from Rockingham and will use them again.

    It happens more often than you think. A Ferrari's offside indicator was not working and they found a mouse nest above the wheel arch liner. The repairs to the wiring loom was quite expensive :o

    I suppose it happens with cars which spend a fair bit of time in the garage and only get out on the road when the weather is good and the roads are dry. Ferraris would fit this description to a T. It also happens to be somewhat true of my 595 Comp, which is a second 'fun' car and isn't used as a daily driver.  The longer it stands the more chance there is of a mouse choosing it as a nice home - especially where I live in the heart of the countryside.  So what I need to do is make sure I drive the car more often - now that can't be a bad idea can it :)

    I thought of this thread watching Salvage Hunters Classic Cars and their Porsche 928. It showed how much damage can be done but the little rodents.

    The good news is I have caught the little blighter. :)  I put down a humane trap yesterday at 3pm and by 10pm we had caught him. A very cute little fieldmouse who obviously thought his winter residence was all sorted. I released him near the farm up the road and, hopefully, he will find new winter quarters in one of their barns.

    (I use the humane traps because, well, they're humane, but also because the steel spring type traps would do a lot of damage to my dog's nose as he went to investigate the bait (peanuts, chocolate and a bit of digestive biscuit). A tenner off Amazon.

    I've left the trap down, with fresh bait, in case he had a mate living with us as well, but so far no sign of any other guests.

    Well done, there is way too much killing in this world.

    I agree. Especially as it is unnecessary in this case anyway. The mouse is only trying to live his life the best way he knows how. I caught another today. It looked like his twin brother so I am wondering if they know how to find their way home and it was the same one. As they clearly love the 595 as much as I do, I took this one for a ride and released him about 5 miles away, again near some farm buildings.  The trap is down again. :)

    The mice always come in twos and threes so keep the traps down .
