can anyone give me some advice please. my turbo stopped cutting in today but i don't think its blown. i only had it replaced just over a year ago. there is no smoke coming from the car. the engine management light came on the day before. also a sign has come up saying "coolant. visit workshop" but the coolant level is full. the radiator fan also came on and won't go off so i've disconnected it till next week when its going to the garage but i'd still like a bit of advice for now if anyone can help
