Vehicle service soon alarm

[Tom.ed82]

Hi everyone, I got a 2014 2 litre diesel Vauxhall insignia. I keep getting a message on the dash saying "vehicle service soon" I then lose power and the car won't go faster than 35 mph, the car has been serviced in the last week, so that's not the problem. I've taken it to 2 garages and they can't find a problem, any advice would be appreciated

I would check that the service lamp has been properly reset.

It has to been done with a scan tool as the oil needs resetting to mileage and this requires the scanner to do this.
