Had it at a mechanic a couple of time go's into limp mode engin light comes on used Obs2 scanners also. Replaced al lot of things and stil have the problem

Audi A4 Avant , engine ALT, transmission 01j, CVT, FF.
High fuel consumption at idle. Crank shaft breather system all new, all filters and fuel pressure regulator was replaced. New OEM spark plugs, new ignition coils, and also cvt fluid. There's no any DTC, just huge fuel consumption, especially at idle

I cannot start the engine, the injectors drop fuel and the sparks plugs light, but the engine does not start
