Overheating warning when should be cold...

[CrafterCamper]

Hi all. I've been busy converting my 2019 Crafter into a camper so it's not been driven much at all. Today I started driving it and got a mile down the road and it came up as an overheating warning. The temperature gauge hadn't even moved from it's cold starting position.

I stopped and switched the engine off. The fan carried on running for a fair while. I let it cool down for 20mins and then decided to see if I could get it home. When I switched it back on the orange engine light was lit but no overheating warning.

I got back home just as it warned me again it was overheating. I've got it booked into a garage next week but wondered if anyone has any ideas what this could be and whether it's perhaps a common fault or easy fix!

Thanks

Have you checked your coolant level? Could be the egr valve - no visible leaks as it leaks coolant into the cylinder head and can cause the engine to hydro lock if your unlucky

Coolant level is normal. Not losing any as far as I can tell...

I did post a reply to what was causing your issue but it appears to have dissapeared.

OK, when the fan is set to 0 the other 2 knobs stay on whatever setting it was set to prior to you turning off the fan. Simply leave the fan on 1 or above and it will work.

Interesting... So you are thinking the setting of the internal fan would cause an engine overheating warning?

I put a code reader on it. It came up with exhaust gas temperature sensor 1 and also low battery voltage. I have had the sensor replaced and also driven the vehicle to charge the battery.

Not had a repeat of the problem so hopefully it's sorted.

You are right, my bad, I read the issue wrong and thought it was internal heater not engine

 

[CrafterCamper]

Haha! No worries. Thanks anyway!

I know it's a moot point as we have all moved on but I was puzzled as to how I managed get my respose so wrong.

Thankfully after a quick search I found out that I was respoding to another thread on the internal heater not blowing cold. Though as silly as a rook I am perhaps not as mad as I think (though my son would disagree)

Good news. Moot point or not... I am glad you have satisfactorily resolved your madness issue!
