458 not revving

Any messages on the screen? I have a 2011 M3 that can barely idle after switching to or from Shell gas. Something about different brands confuses the sensors and it takes a drive cycle before it adapts. Maybe something similar?
Otherwise I'd suspect a cam sensor since the engine can't safely vary valve lift/timing without it and will restrict performance. I've also had that happen from vacuum leaks and vacuum pump failures.
I'd grab a OBD2 scanner and see what codes are there.

 

Have you completely shut the car off - let it sit for 30 minutes - then re-initiate the complete pre-start sequence? I.e. turn the key and wait for the beeping to stop - then wait another second or two - then hit the start button and drive?

I have found my 458 is very sensitive to letting the pre-start sequence fully complete before starting. I have not experienced what you are describing but one possible theory if it has been sitting for a few months coupled with fresh fuel the ECUs and other sensors are confused and kicking in a limiter to protect things - perhaps a full ignition cycle will allow things to synch back up.

Again - just a theory and easy to do - if you have not done it already.

Cheers and hope things smooth out - I can't think it is anything major if there are no messages on the left TFT - Usually 458s will put up a message if you forgot to take your vitamins

 

Cool - Give it a try - As stated these cars (and verified by my Dealer Service tech) are super sensitive to letting the pre-start sequence complete followed by a breath before hitting the button.

I am not sure of any accelerator pedal sensors but given the wealth of knowledge and experience on here others may chime in. Back in the day before drive-by-wire that would be easy to diagnose but harder nowadays.

That does spawn a thought though - Does this situation only occur when in gear and driving or also when the car is stationary and in neutral? In other words if you put the car in neutral and either set the e-brake or put your left foot on the brake and rev the car in neutral does it also cut off at 5K?

NOTE: I would not suggest doing this repeatedly but once or twice is fine and might narrow down the root cause(s).

Let us know - Cheers

 

This is a sincere note. My daily driver has this problem when it's low on oil. Perhaps something easy to check?

 

If it is like the 430 the fuel pumps have 2 speeds, also have you tried shutting the battery power off for 5 mins and see if any better when back on

 

I can only go on my 430 knowledge, the 430 has 2 relays for slow speed fuel pumps and 2 more for high speed. Is 458 direct injection ? So would have high pressure fuel pump, also it will be electronic throttle pedal . Any fuel fitters that might be dirty.

 

Yes mine does. I've given it a quick blip before in neutral and it went to above 5000.

 

Hi
Have you try to clean both throttle...

 

Sounds like a faulty TPS or throttle pedal potentiometer. The latter has been known to fail on 458's. Take it to your dealer and let them look at it.

Did you check for obstructions in the tail pipe? Make sure some idiot didn't jam a potato or something in there. You might also check to see if there has been some sort of failure in the exhaust valves opening. I can't remember but I think they are supposed to open around 3500 RPM's even in sport mode right?

+1 with Il Co-Pilota on the throttle position switch stuff. If that's out of whack, it will raise hell with everything. You might be able to pull TPS sensor data via the OBD2 port.

And let us know afterwards please, it may happen to all of us one day .....

 

How many miles are on the car?

The 458 uses a direct gas injection, which tends to result in carbon building up on the backside of the valves. I don't think that would be the issue, although carbon is always something to be aware of. I once had a leaf blower which suddenly decided it didn't want to rev. I finally traced the issue down to a small carbon spot on the top of the piston, which was glowing hot and acting as a glow plug (sort of like how a model airplane motor fires). I guess it was igniting the combustion chamber at just the wrong time and preventing the motor from revving past maybe 6K RPM's or so.

I would definitely check to see if the vacuum hose and/or control solenoid that handles opening the valves is operational. The ECU which controls that also. Once on my 458, I had the care wig out and decide it was going to operate the valves in reverse for no apparent reason. In sport mode it opened the valves and in race mode it closed them. I had to fix that by resetting the car via battery disconnection.

Definitely interested to see what the cause of this one is.

Very interesting. Glad you got to the bottom of that one!

this is troubling that the dealer couldn’t resolve the issue.
