Ok, a bit sad maybe but I have been monitoring the temperature against the ECC temp setting. I measure the temperature near to one of the intakes in the cab.
In cold weather it keeps it spot on. In warm weather it does not! An example is as follows.
*Got in car and temp was in the high twenties. *Put temp control on 'full cold' (other controls were on auto )and when temp got down to 18 I set the temp control to 18. *The temperature steadily climbed until at 23 C I decided to override the controls by switching the temp to full cold. Like this the temp reduced and but I have to control it using the fan.During the rise in temperature the fan did in crease marginally and the air outlet was cold, but it just was not putting enough effort into the cooling!
I don't think it needs re-gassing as the outlet temp drops to below 10 C when on full cold.
So basically the ECC is ineffective in summer!
Is this likely to be a fault is ECC just like this? The car is a 4 year old V40.
Cheers. Roger.
