Starter & Limp Mode
Day 1: Tried to start my car, battery seemed to be drained. Jump started my car, drove 3 miles & parked for 2 hours. Making a left turn at a four-way light, I accelerated to get around a car. Car accelerated for maybe 30 seconds then felt as if it down-shifted to 2nd gear. I drove ½ mile to my home & parked for the day.
Day 2: car started right up, I drove for a ½ mile in what seemed like limp mode, parked it for the day. Transmission would not shift into reverse, used emergency transmission button to shift, same to park.
Day 3: drove it again for ¼ mile seemed like limp mode. MB II scan: P1025-000, P240C, P2029-000, P2004-000, P201C, P205a-000, D_0001: No system configuration information.
Day 4: car would not start, no clicking, no sound, no rev, no nothing.. Checked battery 12.18 volts, starter relay was fine. MB II scan: Fault in communication with vehicle ECU.
Day 5: MB II scan: Fault in communication with vehicle ECU.
Day 6: car started without hesitation, MB II scan: P201C-000, P205a, P2029-000, P240C. Drove car 50' & parked.
Day 7: car would not start , 5 minutes into MB II scan car started without hesitation, ran scan, turned car off & on 3 times, MB II scan: P201C-000, P205a, P2029-000
Day 8: car does not start, crossed starter relay with a wire & nothing.
Question: Have I lost my starter & my ECU?

Communication fault came out from a automatic scan & didn't give the module.
I ran individual module scans & the typical fault was:
Fault in communication with vehicle ECU
1. This vehicle is equipped with the system
2. This system is an electrical control system
3. The diagnostic connector is OK

Any one have experience with having an ECU rebuilt, positive/negative?
Supposed to be plug & play, it's definitely cheaper than the dealership ...
Appreciate you in advance ...
