Citroen C4 2005, Petrol, UK
Yesterday I managed to overwhelm my car (for the second time I've been having it, first time was about half an year go). What happened was I was at a rather busy stop traffic, trying to make a right. I did at least 30 KMh on first gear, maybe even more, with quite the steep acceleration (pretty much the same thing I did the first time). What was the outcome (apart from making the right as desired) was I overwhelmed my Engine Management System, and having the SERVICE light come on, as well as "Engine management system faulty" board computer warning. This then led to my speed limiter disabling as well (I use it more often than my head lights).
Now I know that I shouldn't have let this happen in the first place, but is there something I can do, after the fault occurred to help the system recover faster ?
Leaving the car overnight helped my speed limiter come back online, and as far as I can remember, the entire thing cleared in few days, when it first happened, but for the now I still get the warning and the SERVICE light is still on.
overwhelm my car? Er, just no. Accelerated the car to red-line condition on the tachometer, much more likely. That engine doesn't like to go 7000, 8000 or 9000 rpm. Things get weird at that speed. Alternator? Air Conditioning? Water Pump? Oil pressure? Injector solenoid speeds? All of those things are direct drive related to crankshaft speed. Did you overwhelm the processor in the engine computer? I seriously doubt it. No manufacturer is going to release a computer with marginal clock/ computing processing times. That just doesn't make sense. Not enough fuel pressure = more likely.
