YI got a E90 323i 2005 100+ miles. It started with a little erratic idle engine on start but when return from mechanic start blowing too much white smoke & taking litres of petrol for couple of miles.

Went to second mechanic.
He replaced
1. Battery, throttle body, Gas Accelerator body throttle with sensor & oil change etc. Gas Accelerator Pedal Throttle Sensor BMW E90 E60 E65 335i 328i 525i 530i 745i | eBay

Cost me a fortune. Now following issues I'm facing & need expert advise before take it back to garage.

FIRST RUN: Outside temperature 104F HOT
Before going on start engine, I got a oil leak problem for which plastic moulding on gasket has been replaced.
1. Wobbly / Shaky Car start - Erratic idle RPM UNDER 800-400 keep shifting
2. Half Engine Light ON, then I start A/c
3. Noticed burning smell plastic or oil, extra heat on engine, cooling fans running on full speed
4. Suddenly all functions stop responding no acceleration, no brake response, engine jerk smooth jerk and ENGINE STOPS
5. Check control messages : HALF ENGINE LIGHT, @, DISC BRAKES, DTC, REDUCED POWER

SECOND RUN:
Engine Light ON but everything responding took car to 120 km/h no problems

WORKED DONE:
1. Battery, throttle body, Gas Accelerator body throttle with sensor & oil change etc.

I know it has mileage on it & wasn't maintained as supposed to be but need help and diagnosis of what exactly are the problems. This is 3rd garage this car went to and still no satisfactory results. PLEASE HELP!!
