Yes, however in my case after a corkscrew downhill drive in a multi story carparK. Light came on and turned off a short bit later. Never came back. Must be gremlins...

 

Yes, happened to me once heading downhill on a motorway slip road. Dealer checked the car and could not find a problem. Problem didn't recur.

 

Thanks both, oddly good to hear others have had this too. It was on a slight downhill incline but very shallow and one I drive every day so it wasn't due to the steep angle giving a false reading. Will ignore if it doesn't come back. Obviously the first thing I checked was the engine temperature which was where it is all the time - bang dead centre.

 

OK I can reproduce this - on the Southbound exit of the M1 at Hemel Hempstead Jn 8. So the good news it's obviously some imbalance with the sensor. If you want to try:

(Obviously do this in the dry, when road is quiet/clear etc)
Come off M1 left lane to HH - enter long right curve at about 55-60mph. At apex of bend accelerate hard out of bend.
Coolant light comes on every time if fast enough. Then goes off pretty quickly when straight.

 

Yes this happened on my v40 D3. After a lot of hassle and 12 weeks in the garage, it turned out to be a leak in the exhaust gas coolant coil where it goes to the egr valve. Got a brand new engine out of it though as they found a split in one of the bores.

I am currently having the same issue! Had my v40 almost a year and it's the 3rd time in 4 months the coolant warning has come on! Despite there being sufficient levels of coolant in it. I even drew a line on the tub last time to check for any low levels, the line is exactly where it was last time. So i've just topped it up a little so that the warning light goes away haha. Could it be a dodgy sensor?

 

What model do you have? Petrol, Diesel, engine type, year?

 

Mine was a leaking bleeder hose near the reservoir, only apparent when pressurised. V40 D3, 7 years old

 

Just had this today, I drive a v40 d2 17plate with about 80k I checked the coolant level and it’s between min and max so not too sure where to go from here, I’ve since started my car and the warning hasn’t come up again. Any advise would be greatly appreciated
