What kok car is that ?

Never heard of ECU need reprogram.

Standard prg have. But many new car have a feature to learn your habit of driving. Adjust RPM timimg according to current engine condition.

But totally lost prg of ECU is bullshit.

It will reset the ECU when power lost. So when power back, sometime the timing run away. Cause the engine current condition is different from new.

You just need to drive like normal for sometime, and it will back to normal. ECU will learn back.

I change my own battery for don't no how many time. Sometime takeout battery to charge and never put back for few day. Or holiday, takeout the battery for few weeks. Don't have such ECU reprogram require.

What kok car need ecu program everytime changed battery?
U over 20k,u tell me.

If u say to reset airbags or esp/abs indicator, acceptable. But ecu??? Seriously??

Jelas sangat kebodohan yang terserlah di sini.
Please, stop posting.

Conti cars dont lose their settings. At most just erase fault codes due to low voltages.

Unless u crank that car with low battery voltage, and keep on cranking till ecu or your navi gateways decided to fry on you.

I drive a conti and I have never heard of a car needing reprogramming   

Is this what you learnt from MIT?Did the private banker fund your studies?

Tulah.... Tulah.. Kan dah kata bodoh tu simpan sikit.....
Do u even know whats an ECU in the first place?
The tered you showed are to reprogram the bmw battery control unit(not the damn ECU) that u have put in a new battery.

If u upgrade from a 90ah to a 100ah and above, u need it. Especially if you fukken drive a first batch F10.

If you are using the exact same model battery, you don't even have to reprogram @recalibrate the batt control unit. For fuk sake!

And there are bugs in the first batch, thats why they were requested to go back and update the BCM. Not ECU.

GODDAMMIT!

lel...bodo sikit2 dah la...malu je...

itu bukan ECU...itu registration battery mah (mAh)...if change battery to different mah..only if..

ECU will never need reprograming...learn la what is ECU...talk cock sing song...

paling kuat ECU reset if no battery power at all...ECU reset also no problem...what was lost is only certain parameter, like throttle sensitivity, ignition timing/ping, all those close loop setting, or gear change pattern (this is TCU not ECU)..

   

jangan la fast n furious sangat...
nampak orang cucuk OBD nak baca fault code mesti lu ingat nak setting engine racing kan?


how can it died, 'while' driving?
alternator kong?
