    z20let engine management light help please

    hi everyone, my mates mk4 astra gsi turbo keeps flashing up with the engine management light, he had it remmapped and the problem started abput a month after so he took it back and they plugged it in and the fault was the lamba sensor so they cleared the fault and he fit a new one, around 50 miles later it came back on plugged in again same fault so he took the lamba sensor back and asked for a new one witch they did drove for a while and engine management light again, he took it back to the place where he had it mapped and they put the standard map back on to see if it was a problem with there map, he drove 100 miles and pop light back on, no problem with the drive, no limp mode just keeps coming up with a lamba sensor fault has anybody experienced this and if so how was it solved? thanks in advance

    If its like the zaffy gsi , i think that there are two lamba sensors, failing that, if its the light that looks like an engine, could be the afm, it was on mine, after the garage had fitted new lamba sensors!!!!

    he doesnt know the actual code mate just that its lamba sensor 1 but like we both said lamba sensor 1 is where it will pic the problem up so it could be anything before that but im almost positive its the air flow meter, they are prone on all vauxhalls lol its just the meter is £100 and he is worried that it wont solve it. we are in leeds bud

    Mine used to come on when i had a cone filter fitted to my gsi. Turned out to be a faulty AFM. If you change it over to simply trial it you should well feel a difference immediately as limp mode is noticeably slower. Gd luck mate.
