Yesterday with ignition on the vcds was showing the o2 active as 1.0 tonight after repairing cable its 1.85 so made a difference before even starting it up.will tell 2moro how it is.im not really sure what the vcds o2 active actually is monitoring

My theory is no contact no voltage.no voltage makes ecu think its running weak or sensor fail if it does fail or think its weak it automatically puts an extra 25% fuel in as a fail safe

Well wont be getting continuity through that terminal its the earth for sensor side not for heater side.hopefully found the problem

A ride up to Cumbria Vag in the sun.

Ok new cap fitted 310cc injectors and chip back in running much better this .code o2 sensor limit surpassed i had forgot i had this fault before fitting charger i presumed i cured it by buying a new bosch lamda.obviously hadnt and this is why im running rich even more so with bigger injectors etc.lambda plug on car loom has 4 wires the yellow that connects to pin 42 in ecu i think is the ground for sensor has corrosion on terminal.im thinking as the lambda detects a lean mixture the voltage would be low and if rich it would be high.as ive got a corroded terminal id have no voltage to sensor s

thanks for advice chaps..mine has square indicators but obd socket is by ashtray??..but is obd1....think I have 280 brakes(if so i have a brand new set of 288 discs for sale!)..bealie.how are u.... Pm me a price dude..thanks cheers lads..
