Hi, I've had my S3 nearly a month now and since Ive had it its had these big red symbols coming up on the auto check cycle, I checked the manual and these relate to oil pressure and coolant, though I had the car serviced about 2 weeks ago and had a full fresh 5L of Shell Helix Ultra 5w-30 with new filter and full topped with coolant, Ive checked both and and they seem fine. During that service I had the engine coolant temp sensor replaced with the superseded part as this was giving a fault code but its been on the snap-on diag since and all is clear! The car itself seems fine other than perhaps being a little rough for my liking on first start but hey there was ice on the winscreen when i started it so the cold wasnt helping lol, Audi recently done a coil change and health check and nothing raised... I dont want to leave it till it goes bang so can I get some urgent help guys!!!
