740 & 760 Lambda light
Help please can anyone tell me which pins I Cross connect to remove the code for the lambda light in my 1990 740. Have fixed the exhaust system leak but even after disconnecting the battery and re connecting the bloody thing comes back on. Don't have any fancy code reading boxes unfortunately. Bill

See the 700 / 900 FAQ for how the read and clear codes with it.
