RW1 0 Posted June 18, 2005 that mean it doesnt matter when you change the battery on a 16v? havent been able to find anything of great detail bout it. KR 1.8 ltr, no set up after electrical power loss. 9A 2.0ltr, well yes but not like the VR6. More a check than a set up procedure. Should also be done at the service intervals. ECU is 8A0 907 404L or 404CC You will need VAG-COM at v409.0 standard. Earlier versions such as v311.2 won't work with this ECU family. Also need to set the "Start Baud" to 4800 in the options before you interrogate otherwise the ECU digital communication "chokes". To reset the ECU comms you have to turn off the ignition and back on. After power loss such as a battery change or a service, warm the engine upto normal operating temperature and do the following check: Put the engine ECU into "Basic Settings" and then select group 000. Raise the engine revs to 3,000 rpm for 3 seconds and then allow to idle for a further minute. (if the Corrado 16v 2.0ltr is an Auto, P or N must be selected during this test) Now check that field 9 has a value of 5 in it. If not, then you are looking at other values. These values determine where the fault or combination of faults. They relate to micro-switches, CO level, ignition timing amongst other things. A lot of diagnosis with "if" and "then this".
