Hi all, having a few issues with my girlfriends 2004 A3 2.0 tdi. Firstly the radiator fan keeps coming on really soon after starting, I have replaced the coolant stat as that's what it was before when it happened. But still have the same problem. Also last night after 20 minutes of motorway driving the coil light started flashing on the dash and it went into limp mode with no power at all. When I got home I turned the engine off and back on again and it stopped. Today to be safe I got the car scanned for faults and it came back with the following codes: 18359 coolant fan, 18358 coolant fan, 16610 throttle position sensor. Iv had a quick look on here but can't make sense of what it could be as there seems to be so many different opinions. Any help would be greatly appreciated.
