Ramasesuk Posted August 7, 2017 Share Posted August 7, 2017 Hi my A3 1.8 turbo has engine warning light on and the esp light the only engine code i have got off of it so far is this one "16487 air flow sensor (g70) signal to high p0103" There is another about water temp sensor but will have to get the code again as i forgot to I have changed a wheel speed sensor which afrer a few day the light went off but then came back on a few days later. If anyone knows what that code actually refers to and what sort of cost i am looking at i would much appreciate it. Quote Link to comment Share on other sites More sharing options...
Trevor Posted August 15, 2017 Share Posted August 15, 2017 Hi Ian I would personally address the issue with the coolant temperature sensor first as if there is a fault there (defective sensor or wiring/connection) then that could invoke the code for the Air Flow Sensor and other associated problems. Maybe best to list all of the codes you have and we can look at them all individually Quote Link to comment Share on other sites More sharing options...
