Citroen C4 2005, Petrol

Very rarely I happen to turn without braking properly and my forward momentum is quite high. In these situations I can feel the strain on my front wheels being very high. What happens occasionally is, my SERVICE light comes on for just a second, while the turning lasts and then when normal operations resume, the light goes off as if nothing happened.

My questions is, what exactly is being triggered here? What system gets overwhelmed, and why?

It could be that you are cornering so hard that you're pushing the oil in the sump to one side, away from the pickup pipe. This temporarily means you're oil pump is sucking up air and you are starving your engine of oil.

Competition cars are equipped with with baffled sumps or dry sump systems to prevent this happening. In a standard road car, this type of cornering is best avoided if at all possible.
