    Hi, since a couple of weeks, I get the suspension warning light after every cold start. And only after a cold start. If I drive a few miles, stop the car and start it again, the light does not come again. The same is, if I have several stops during the day, no more suspension warning light. But the next morning the check light is there again after the first start. Any ideas what to check first? Thx

    Mine did the same after a winter on lift and wheels off. Disappeared in spring when I started driving it regularly

    I would take the car to someone with a Ferrari SD1 tool. The fault will be stored in the Suspension ECU memory. A lot easier than chasing intermittent defects. If it's a suspension actuator, in most cases, these can be repaired by CaptainZ CNC in the USA.

    Most common cause is (1) low voltage (put on a tender) (2) suspension actuator (3) loose / dirty connector. I have had 1 and 3 already; just waiting for #2

    It has happened to me once or twice when I started it a bunch of times but did not drive it.
    As soon as I drive it goes away permanently.

    Oh and once due to low tire pressure I believe. Could that be the culprit ?

    456M has no clue what tire pressures are. ABS would only care about tire diameter.

    Sounds more like something is loose connector wise.
