If this works can anyone give me any ideas why I'm getting a mil flickering??? No faults logged
Lambda 1 looks a bit dodgy but then so does volts

[kstead]

By volts I mean battery voltage
Mil light flickers randomly and she's started to bang and pop an awful lot more than normally. Just like the last time I lost a lambda

Are you just having a mil light flickering ?
Or do you also loose some power etc...

[kstead]

Yeah just flickering mil, power is fine, ears are ringing

Battery voltage looks low. It should be mid 12's.
When my big fuse failed it was sub 12 and all sorts of electrical gremlins.
Once sorted gremlins went & it ran smoother too.

Was the garage hot when testing? Because the air temp looks high?
Yes that Lambada needs checking.

If the MIL is lighting without the ECU logging a fault then it is likely to be a wiring issue, not generated by the ECU. Everything looks normal to me apart from the voltage.

I was really surprised there was no faults logged, thought I was getting my head round the whole diags thing.. Does every fault log or 1st value mil light 2nd value log???

Every time the ECU lights the MIL it logs the fault and that stays in memory until you clear the fault log using the menu option. Is the buzzer sounding when the MIL flickers? If not then I would suspect that the MIL is lighting for reasons other than the ECU i.e. a wiring problem/bad connection.

The buzzer doesn't seem to be audible on some cars - there is a volume control on the back of the dash circuit board. If you can hear the buzzer when the ignition is turned on but not when your MIL is flickering then my money would be on wiring.

Its always worth checking the big fuse. It is only in the circuit between the alternator and the battery so isn't directly responsible for anything other than the battery not charging, but with the battery taken out of the charging circuit odd things happen (like bouncing rev counter) presumably due to the missing regulating effect of the battery.

Yeah getting a beep too, think my big fuse has been removed. Bought a big one and there was nowhere to put it!! Lol
Got a lambda on the way so I'll swap it anyway, also maybe worth keeping the laptop connected and recording the fault to see what's going on

[Snake278]

If you don't know where the fuse must be just follow the red wire form the back of your alternator, you will find the box (which should be on the coil bracket )

A faulty lambda will screw the adaptive readings ? No ? Here they look fine...
