Jasper,

Thank you,
Yes the testpads are the same in 07 and 06 ECUs.
However, I still not succeeded in the ECU recovery, and trying to figure out where's the catch.

Do I still need to tie the C446 capacitor to the ground wire as shown at your picture?

Most Multimeters are RMS meters which means they will show the average which in this case should be roughly half which is 2.5 Volts. It's not a nice approach but at least it gives you a clue of what might be wrong.

The multimeter reads roughly +5V at the WDT pin

Thanks,
Anton.
