'Service vehicle soon' message

[caretaker]

Hi All,
I just had a message on my vehicle, Vauxhall Astra 1.7cdti elite, 5 door, A17DTR engine, 61Reg. It does not have the Start and Stop.

It shows "Service Vehicle Soon" it has the car symbol and spanner in the middle illuminated in yellow.

It disappears when i press the reset button, but it comes on ,when ever i start the car. it does not come when i am driving the car, as i have already reset the sign Service Vehicle Soon.

I had breakdown recovery and called them out, as it was just a local recovery guy and he said nothing to worry about, as you need to reset it from the ECU ,as it is a message to say you need your car servicing, as it is now 37,700. I told i had my car serviced when it was around 34,000 miles. But he insisted there is No fault he put his OBD reader and from his mobile screen , there was no faults reading all clear. He told me you will have to take it to the garage and reset the Ecu to tell the ECU the car has been serviced.

So this is the reason i posted this, as reading about the "Service Vehicle Soon" i was understanding there is a fault and from the recovery guy OBD reading it was showing NO FAULTS. I am bit confused

I would appreciated your guys advice.

I dont have problem with the car even though this signs lights up, as it is driving as normal.
