Hello, not sure if anyone can help me, I got myself a 2003 Vito 108 cdi recently and all is well apart from one thing. Whilst driving on a motorway at 70 mph (ish) I have had a 'bleeping' noise like a warning alarm, yet no lights come on the dashboard and it only lasts for about 5 seconds and then doesn't do it again, this has happened on two seperate occasions now. I have seen that in some cases it is the handbrake alarm thing but as no lights come on the dashboard and the handbrake is not on I am unsure what it can be and can't find anyone who has had the same problem. All the warning lights on the dashboard work so it's not that a bulb has gone or something and that's why no warning lights come on when it beeps. Any help and I would be very grateful.
