Resolved one problem to then get another with coolant loss
My daughter has had this 1.4 petrol C3 for a couple of months and apart from the starting problem (now resolved) its been running fine
She does mostly local trips of only a few miles, every week or two a 30 mile round trip to nearest town, then occasional trips to visit family of a 320 mile round trip, and its been fine until a few days ago when about 10 miles from home the temp light came on with a stop car warning on the central console
She pulled over immediately and let it cool down, then opened the coolant cap to find no coolant visible, she then called me, I took plenty of water but on checking around the engine bay and underneath, found nothing amiss, so added some water, it only required under about half a litre or so to bring up the level, checked the dipstick, no sign of water droplets in the oil, nothing else obvious so just assumed it was a lack of top up, the reservoir was dirty and it looked like it was between the min - max level until you cleaned it, daughter said she had checked and thought it was okay without removing the cap , so off she went and all was well it seemed
Three days later and she was going to do a 160 round trip to visit her sister yesterday, she checked the levels to find the coolant gone again, at least the level was down to the bottom of the reservoir
No sign of water loss anywhere obvious, no obvious water droplets in the oil (which might have suggested a head gasket)
Googling and checking the forum archives found confusing results
Can anyone suggest any reason for the water loss
Are there known problems of water loss with the 1.4 C3 ?
