Default Probably ECU problem?

Hello!

I'm having problems with my car..
I'm suspecting is ECU.

Sometimes when I start my car, wippers start to wipe and stop after several seconds, also while driving I get an yellow ABS light, but not all the time, I just turn off engine, start it again, and It's good, ABS is working normal untill I get yellow ABS light, around 30mins~ of driving untill it shows.

Also I have a problem with oil light (yellow, it means low oil)
I checked oil and car is full of oil, also it shows sometimes, today it didnt but yesterday did.

Thanks!

Sounds like you have multiple problems. There is a separate ecu for the engine , abs , srs , & body control. It would be best to get a full scan on the vehicle before going any further & throwing parts at it.

I get your point.
I changed like 80% of sensors on vehicle.
But every week I encounter a new problem, car is working normal, normal driving, shifting, accelerating, everything normal. Only those lights are really confusing me.

I was at my dealer and he tried to connect car but no luck, it didnt recognized it, while I was at another one and he suceed to connect on, but he just made error cleaning.

Do you have any suggestion what should I do? What kind of car diagnostic to use?

Thanks

If there is a communication problem then somthing is bring down the can circuit. The dealer should be able to diagnose it if you are willing to pay for the diagnosis.
