Vito 110 - 638 1999 2.2 Diesel
Hello!

Im having issues with my Vito when starting hot. I'll describe the problem first then give you a bit of background.

Its a Vito 110, 1999 model, 2.2 Diesel.

Its starts fine cold, but when it warms up I switch the ignition off, then when I try to turn it back on... nothing, there is no power at the switch.

The temp gauge goes up, then instantly drops again, then the engine oil light comes on. If I leave it for a while it will eventually start again. This depends on how long I have been driving it, after a long 1-2 hours drive, I've had to wait 4-5h hours, one time a couple of days.

You can see a video I made here:


I have the van running at normal operating temperature, then I switch off the ignition, then when I switch it back on again you can see the temperature gauge go up and back down again instantly, then the oil light switches on. When I try the ignition, nothing, no power at all. Then when I switch the ignition off you can see the speedo and rev counter flicker a bit.

It had a new battery when I brought it a few months ago, but it seems to drain super quick. When i first got it, if I left it standing for 10 - 12 days the battery would be drained (still enough to power lights and windows) and it wouldn’t start.

Now the battery is completely flat dead (no lights at all) if I leave it 4 days.

When there is power in the battery and I switch the ignition on, the lights on the dash are dim and slowly get brighter.

The van is old and the body is rusty so not sure if the earth is getting a good connection, I did clean it up and it looks ok.

Im going to try changing the battery and earth strap and see what they does.

I've also just change the thermostat, housing and sensor. Before the dash would not go above 40, now it goes up to 80.

I was hoping the new sensor might fix the issue, as the temperature gauge was doing that weird thing, but still no joy.

Any help is much appreciated!!

Thanks in advance.
