So yesterday, after a nice drive (hot ambient temp), I parked the car and it (obviously) cooled down for several hours: I start her up again and after a minute ..... I take off really hard down the road in first gear and then just backed off the accelerator ..... and after a few seconds more down the road, the "check engine light" starts blinking. The blinking stopped after two minutes or so ..... and, that was all. I felt nothing weird in the way the car was operating.
Any ideas? Maybe I overwhelmed the sensors with the full bore high rpm blast on a relatively cool engine ??
It just blinked for a short while and then disappeared.:confused:

Are you sure it wasn't the traction control?

Shame on you,with your wealth of experience ??!!! She must be telling you to cool it,remember she wont let you rev her at standstill till you've turned on the heat a little,then you know shes a goer !!!
Like you its the only answer I can come up with!

Nope ..... It was the little yellow engine block symbol, that was rhythmically flashing. My guess: My stupidity threw the ECU module for a loop because the car was not warmed up yet, when I nailed the accelerator and it possibly caused a weird air/fuel anomaly, when I quickly lifted off the loud pedal. (All I experienced was a few minutes of the flashing telltale, then it extinguished; the lamp never went on steady).
I started the car today ..... and, everything was normal; no messages in the 'Error Message" screen, either.
BTW ..... Once on my LP560, I tried the same stunt but the car's computer would not allow the rpm's to go above a certain level. I surmise the 12C's answer to this was to throw up the 'check engine' light.

The aventador doesn't let me either .... But not sure if the mac allows it or not. I do remark that the engine quickly gets on temp. Just a few roads further and all ok. Just for safety I drive a few miles (allways) to warm them up properly. One does need to respect mechanics!!

I just had the same issue where under medium load while cruising I would get a hesitation/steering shake/flashing check engine light. Long story short, turned out being two bad coils. Replaced coils and running so much better now. Before I was able to make the issue replicate, now it’s totally gone and even idles a lot smoother. Still worried about that flywheel spring that everyone mentions, so will at some point get that looked at to make sure mine is ok,

Dont forget the check engine light is a monitor for a host of different engine data points.
Possibly the hard acceleration on cold threw up a message from exhaust/oxygen sensors (i dunno)

But our mac techs tell us if something like that happens while doing something unusual and then the light doesn't come on again then not to worry. Only worry if it happens again.

Over the years with my 2 Mac's have had a couple of one off things like this that never ever reappeared
