My first Vauxhall, 2.0 dti Zafira Comfort 52 plate. 3 miles from picking it up from the garage the car/spanner light comes on and it goes into limp mode! Pulled over turned off and on again light goes out, 1 mile later back on again! Any ideas as I have emailed the garage (see what their response is) would be good to get an idea so I don't get fobbed off!Thanks
