Engine management light?

[EPnick22]

right ive just wired up my speed limit defencer, went for a quick test to make sure it works and it does, car doesnt run any differently in the slightest, everything smooth as always, when i booted it down the motorway my engine management light came on, i pulled over in the lay by, checked my oil and was real low (changing it today) when i turned my ignition back on, the light was gone, then when i booted it again it came on? i have FCD fitted but its never done this before

FCD's are an accident waiting to happen.

Sorry this doesn't help you but its true.

[H_D]

Have u done a diagnostic check?

Any codes come up?

what would happen then? its been in there for a few years, runs a bit rich, nothings changed, but why would the light come on?

not yet it only happened today, im going to try getting it plugged in during the week at some point!

[EPnick22]

bump!! apparently my local garage cant plug the car in due to not having an OBD port? how am i meant to know what my eml is coming on for?!

[akyakapotter]

Do the test your self id say its the start of fuel cut as your now able to go faster CLICK HERE

[EPnick22]

its never done it before though, and i can redline every gear (not that i do ) full boost etc and it doesnt come on, i could just be cruising off the boost and itll randomly come on, then disappear when i turn the car off, then on again?

[akyakapotter]

do the test in the link above bud and it will tell you whats up

[EPnick22]

i read that all through and im beyond tired at the moment so maybe have a look tomorrow ill give it a go

[akyakapotter]

will take you less than 5mins to do it all you need is a paper clip pen and pad to wright down the result

[EPnick22]

a paperclip to connect the 2 pins up right so it appears on the dash?

[akyakapotter]

yep to bridge te1 and e1 then ignition on and see how may times the eml flashes will flash say twice then seven = code 27 ect

if you test it she will proberly show fault code 42 like mine did as my cable was not connected (that's my speedo cable by the way) check my link

here http://www.ukstarletowners.com/topic/66490-ecu-diagnostic-codes/

basically ecu code 42 Vehicle Speed Sensor (VSS)
No speed sensor signal to ECU when loaded driving condition with engine speeds 2000 to 5000 rpm. in 5th gear driving
For 8 seconds or more.

check it out pal see if the link helps

[EPnick22]

I'll check that at some point after work today dude, sounds like the most likely problem! I just thought it was funny how even when i dont boost it came on, but if i go boosting around it didn't come on haha

Bridge te1 and e1 with a paper clip turn ignition to ignition on eml will flash up with codes or constantly flash if no faults stored.
