I started my F430 a couple of days back and it was running rough with no power from low down. I called the garage and they said to re-set the ECU/s by turning the isolator key under the hood off and leaving it for a minute and then switch it back on and try to start it again. First of all 2008 model has no isolator key, so I have to get at the battery to remove the earth strap. Then I start the car ... no problem it's back to its usual instant throttle response, pulls from low down etc. Two hours later I go to start the car and its back to running rough. I think the rough running is "the limp home" mode of the ecu but my garage (who now have the car) say they can't find a fault (though they do acknowledge it had a fault when it was picked up) with the car and all diagnostics check out OK. does any one here know of any similar F430 problems or is this a "one off" ? F.C.
Care to expand on this? I'm interested in what others have experienced, I have a notion that this may not be the last time this happens and four year warranty or not I don't intend waiting on the sidelines for my car to re-appear from the workshop every few weeks. F.C.
Happened to me about a week ago. I just shut down the engine and restarted and everything has been fine since. Based on the above, I suspect it may heppen again.
rough running or lack of power??? first off ideally what u want to be doing is switching the ignition on and waiting for "check ok" to appear on ur dash before starting... and ESPECIALLY before you put ur foot on the accelerator pedal. When u switch ur ignition on u'll hear 2 clicks from the throttle bodies, it is very important that this procedure isn't interrupted by pressing the accelerator pedal. when this fault occurs does it appear as though the car doesn't start with the same "kick" of revs??
I got Ferrari service to take it away. They turned up within an hour of my call. The workshop said that all diagnostics were clear, and I have the car back. It has been running perfectly for a couple of weeks no with no sign of the trouble re-occuring. As an aside the workshop aknowledged that the car was running on FOUR!! cylinders when they started it but there were no indicator lights or flags on diagnostic. They re-set the adaptive mapping on the ecu and asked me to "keep an eye on it". F.C.
You are not the only 430 owner with this problem. I suggest you also watch your battery voltage. If your battery is not holding its full charge, the low voltage can throw the computers off especially at start up.
The same problem happened to me last week as well where the car ('07 430) felt heavy when revving and it felt and sounded like not all the cylinders were firing. After 15 mins pulled over turned engine off and restarted a few minutes later and it was back to normal with no faults....
I had the same problem with my 08. The dealer installed new software and that solved the problem. Definitely it seemed like the car was running on four cylinders. The exhaust sounded funny and it had no power. There was nothing on the dash lights to indicate anything was wrong. I would shut it off and restart and the problem would go away. So someone in FNA tech service must know how to fix it. After the new software, it never happened again.
I stopped my 07 F1 for a quick pit stop yesterday after a heated run.. It started up no problems, but i was 1/4 mile down a side road.. upon entering the main road (up a stiff incline), I hit it and the revs just dropped off.. I thought it was clutch slippage at first, but no smell.. I continued down the road and it stumbled a bit .. About a minute later I had to stop for a light and when it shifted back into first, a buzzer alarm sounded as it almost stalled.. It came back to full power pulling away from the light and has run fine ever since. I attributed it to the hot start, but now am not sure after reading the thread.
Thanks BDELP. I think I'll do this too, unfortunately no authorized agent where I am. So I'll have to fly out a technician to fix this.
I resurrect this thread from 14 years ago - not sure you guys have still your F430 ... I have the exact same problem on my 2005 F430, Dealer sees nothing in the dash and diagnosis, unless some misfires. they did road tests and say the car runs like a charm - but I definitely have a loss of power - the car runs like on 4 instead of 8 cylinders. I stopped, restarted but seems like the issue is still there unfortunately, and just 130km off the dealer
I've been having this issue intermittently with my 2008 F430. Usually a restart or 2 will eventually fix it. I seem to notice it happens more often after the car has been sitting for more than a week and i start it too quickly without waiting for check engine lights. Here's a video of the rough idle with no warning lights. Definitely feels like limp mode. Any fixes? https://youtube.com/shorts/LQhfYnf3nSM?si=7DNxOIZE_WqxDvAk
One thing I will point out is sometimes you can start a 430 too quickly, I would try turning the ignition on giving it a good 10-20 seconds before starting the car and you may possibly find it doesn't happen again.
Any others with this issue and how it was rectified. Trying to resolve 430 Scuderia with intermittent cold start problem, appears only one cylinder bank is functioning. One has to wait awhile before doing a restart and hoping engine operates correctly. Just had both Ignition Electronic Control Units checked by a specialty shop and still have this intermittent problem.
It is a common issue. I have noticed it with a bunch of different F430s, happens when starting the car from cold. It will start and only run on four cylinders. Shutting the car off and restarting will make it run on all eight cylinders. When working at the dealership and an independent shop, I would have to move all of the cars from the service department out to the parking lot in the morning and then back in at the end of the day. F430's were in for service would exhibit this fault, and there was never a fix to be found. It may be a software issue, but Ferrari did not issue any information about it.
Just my two cents on this. I've had this happen only once before, it was when my thumb somehow slipped off the start button instead of holding to crank and start. So it cranked for a second, stopped, then I pressed and held again and it started, but only on one bank. I thought for sure I broke it, and a stressful 5 mile drive to work commenced. I always knew I needed to wait for it to complete its checks, but my approach is always turn the key, touch nothing, wait until the CHECK OK on the dash, the F1 pump finishes priming, and even the seat belt beep to stop. Only then do I pop it in neutral and start (for the record I do realize it will do this on its own if it's in gear but I figure one less thing for it to potentially flake out over). Doesn't matter if it's the first start after a month of sitting or the 4th day in a row of driving, I've never had the issue other than that one time.
If ur battery is over 2yrs old and not the best one you can get and kept on tender if not started for 2-3 days it will happen also in winter more so as batt voltage sags in low temps and harder to turn over
Another issue easy to throw money at. Mine developed this problem, and I replaced the MAF's which helped but it wasn't perfect. I pulled the injectors, cleaned and put in new seals and now it fires hard first time every time regardless of how long it sits (tendered).
Update on issue; 2008 430 Scuderia with intermittent cold start problem, appears only one cylinder bank is functioning correctly. Both Ignition ECUs checked out fine. Replaced one micro relay and so far, five engine cold starts have been normal. The new relay installed is Bosch 0 332 011 007 - 896 475 250 25D Ferrari & Maserati part number: 000 227 286 30 Amp
Do you know which relay? Motronic relay (PSR10 (Left) or PDR10 (Right))? Pump relay? Key operated devices relay?
The intermittent cold start issue was with the left cylinder bank of engine. Replaced micro-relay: position PSR8; left hand fuel - pump speed 1 The relay is located inside the passenger compartment, behind the driver’s seat, electrical section on firewall at floor, inside a relay holder box. See the owner’s manual pages, exact location is PSR8 shown on Diagram D, Page 124. Image Unavailable, Please Login Image Unavailable, Please Login
Thanks. Makes sense. I guess these high power relays wear out eventually. I assume page 125 has the listing for PSR8.
