Hi all.
Problem of oil pressure lamp taking 3 seconds to go out on initial start up.
I know this topic has been discussed before but I would like to know if this happens to all crdis or is it due to a faulty non return valve allowing oil to drain back into the sump. My dealer says it is normal but I am not convinced as on all other cars I have had the light went out immediately on start up. I have also noticed that it does not take too long after stopping before the same issue is there on restart. Usually if left for an hour. If this is a non return problem then there must be unusual wear taking place every time we start these cars
