Missing Engine Check Light

My 2005 D3 failed its french MoT this week - both fog lights cracked and misted up but working and beam aim unaffected.- replacement ordered

Secondly no MIL orange engine light on position II

I had upgraded the software last week using the IID Tool (MY07+ for a pre MY07 vehicle) - when I checked I/O vaules I could toggle the MIL light on/off ok so bulb was working

In CCF - no option to change MIL status at all to enabled/disabled not listed

Downgraded the software back to pre MY07 and now the MIL light is working in ignition position II and goes out when I start the car

The engine is the 4.4 V8

thanks

the other strange effect of the upgrade was to give me a low collant warning light even though the coolant was at the correct level
downgrading the software back to pre MY07+ also cleared that one

You flashed it with the wrong software.

Its a V8 engine that does not have a FBH, so that might be confusing it with software for a 2.7 engine.

The 2005 and 2007 V8 dash has the MIL light in a different position.
It will now light the orange Park Brake light instead.

Ask me how I know.

PS I need to return to the 2005 software now can I just reprogram ov er the 2007 software?
