Benb Posted August 20, 2019 Share Posted August 20, 2019 Hi guys, I have an audi a3 1.9tdi 08 plate The engine management light come up. A garage diagnose it as a ecu - needed new ecu. But a friend of mine had a look and found a box with pipes coming off, one of them had a screw hanging out the pipe. Anyone have any idea on this box and what it does. Any help much appreciated.
