My A2 had a black-out while driving

[kiklop123]

Last time while on highway, driving 100km/h, my A2 suddenly stopped. The servo light went on (i think it was yellow), oil lamp went on (red), and beep signal.
As i was in a tunnel, i pressed the clutch and put in neutral, hoping to get out of the tunnel. I managed. When out and still rolling, i start the engine. It started normaly, no problems or error light went on.
I made a OBD scan and got this. The problem codes are under 17 Instruments. As my CCU is not original (old CCU problems with lights, doors...) the codes connected with this dont worry me. But the 001176-Key and 01374-ECM does. can anyone help? Please share your opinions.

I would check the connectors on the rear of the instrument cluster, it might be as simple as one of them not being seated correctly.
Has the cluster been worked on recently or could the wiring have been disturbed?

Thank you Catnip64. If it is only loosn connector, than i am verylucky.
In any case, taking a car to my mechanic as service interval is near.
However i was soooo shocked, when the engine simply stop working. I didint think this is possibile. Because without engine running brakes are (almost) off, sterrring as well.

Hi kiklop,

My 1.4 petrol had a few issues today, first started with EML and error 1314, then drove ok but every time I slowed down for a corner went in to limp mode until I turned it on and off again. A different error code of 17961. All this happened after an oil change. I had a look at the exhaust seeing if there was any cause there as it is a bit homemade at the flexible end but noticed that I had slightly dislodged the plastic pipe from the service flap oil filler. Clipped it back on. All happy.

Hope yours is as simple a problem.

Tony.
