As for them being archaic DUR
they were designed nigh on 30 years ago - what do you expect 50nano metre circuitry?
Perhaps you should consider buying a newer car mate if a Mk3 Escort is too archaic for you
Mate i KNOW its the ECU, if it reset they would ALL flash the same as when the ignition is turned on.
As i say, the dipstick oil level shouldn't work after about 5 secs as the engine is running and obvious the level will read as low.
Sometimes my fuel light decides to come on aswell well i know i have a good £10 in there, and your guna say driving round corners.....but the ecu monitors the sensors and the light wont illuminate/distinguish until the sensor has been continuously in a changed state for 7 seconds of more, to avoid random flickering lights when going round corners etc.
It does it so rarely that i can't be arsed to change it.......but it proves what they can be like.
And all the wiring is MINT.
