So today my car went to the garage to get diagnosed, they got a fault code and it says its to do with a fuel circulation fault. One of the things i haven't changed so far is cleaning the throttle body. So can anyone give me a detailed guide to cleaning it, please? As i thought i may as well give this a go before taking it to Renault to attempt to get fixed, but they will probably just end up changing everything i have done and charging me £££ just for the privilege. And then it not actually be fixed, so yea, Little help
