as the title states how can you reset an ECU ppl?? could this be done via vag-com ( erasing the DTC or something like that?)

im curious as to why you would want to ?

cleaned and disconnected some sensors so I would like the ECU to learn the new readings (if it does actually learn them)

im sure i remember reading somewhere you just have to disconnect the negative terminal on the battery

If you have an error code, youll most likely need VAGCOM or as its now called, VCDS to clear the faults as the negative battery trick doesnt work well on these modern ECUs

I don't actually have error codes but as some of the sensors are now cleaner I would like the ecu to "learn" on the new readings if it is actually an adaptive ecu after all

btw talking about sensors the fuel meter is not working quite well all the time ... it should be the sender from the tank no??

i think so theres like a float mechanism on the fuel pump inside the tank,(can be accessed from under the rear seats) i got a feeling the sensor is inside the pump, bit of a b**** to get to

yeah I tried to open it some days back!! the connectors and hoses were a little tough and I left everything untouched so not to break anything!!

It'll automatically adapt without any reset needed if it needs to change.
