Can someone on here help please?
I have a astra sri cdti 150
At lunch time today I was f***ing around with the radio when "test mode" appeared . I switched off the radio and had to go back to work.
When I drove home the car felt sluggish and the turbo doesn't seem to kick in until at least 2k revs...
Dont know what to do ???? There are no lights on the display or dash indicating a fault in the system.
