coding problem
check engine with vag tool got a error
3510 low voltage this is the second time i got this error code the first time i took it the dealer told him the problem. i resently change my ecu back to stock would this cause the problem. also i check the readiness some of the instruments read fail i remember i check this after the dealer had it the readiness read all zero's now it reads 01011010 0how can i change it back to all zeros

Every time the ECU loses power it will log DTC18010
"Power Supply B+ Terminal 30 Low Voltage"
So yes, after swapping your stock ECU back in, you will see this error.
Also, after losing power, the ECU will reset its emissions readiness status bits to all '1's.
The readiness code will be reset to all '0's after a short drive (about 30 minutes) provided all the emissions systems are ok. There is also a formal procedure to zero out the readiness code without driving, but it is way too long and tedious to go through. You are better off just driving.
