guys, cant describe the actual light that comes on in my car, is there an image on here and i can show you which one it is?
the light in question comes on after ive been driving for about 10 minutes, then goes off after about 1 or 2 minutes, then other times it doesnt come on at all, should i be worried?

Picture of an engine? If so, paperclip it.

I think all other orange ones have letters written on it?

The orange symbol looks like a sort of tap

it hasn't come on for 2 days and is very intermittent

OH BUGGER!
My fault is the middle symptom
should i not drive it?
it only had a new exhaust and cats about 2 years ago
i hardly use the bloody thing

Exhaust emission
Control indicator lights up when ignition is
switched on. Goes out shortly after engine
starts.

If it lights up when the engine is running:
Fault in the emission control system. The
permissible emission limits may be exceeded.
Consult a Vauxhal l Dealership immediately.

If it flashes when the engine is running:
Fault which may damage the catalytic
converter – see page 150.

Wayne - you car does not have an emmissions light - on the 2.5 (and 3.0), that symbol is actually the Engine Management light.

This means the engine ECU has detected a fault.

Look in the Maintenence Guides Index for Paperclip test, and post up results

And at the moment, don't panic, just post up the results of that test

- we'll let you know when its time to panic

amba · « **Reply #14 on:** 20 December 2010, 23:34:17 »

Must be contagious as I have had eml come on and off for most of the day.

I did a paperclip read and it came up as "89" which I am assuming is the n/s lambda sensor possible playing up...may be a loose wire or the sensor is on its way out.

I do have a spare lamba so when can get under car in dry will get them swopped over as another 4-6 inches of snow has fallen today.

Strange thing is car is running fine with no hesitation or uneven tick over so not much to worry about ...I hope.

Do the clip test wayne...you may find a similar problem as mine.

amba · « **Reply #23 on:** 23 December 2010, 11:40:22 »

It indicates the engine managment has detected a fault which requires rectifying.

Only way to trace is read codes stored in ecu and then advise.

As your car model is able to provide stored codes by doing paperclip test,that should be your first course of action.

Without that it is impossible to establish if major/minor or non existant.

okay then

done a paperclip test
it flashes once, then flashes twice a few times, thats normal isnt it?

after that, it flashed once followed by another 6 flashes, it done that a few times, then back to the flash once and flash twice scenario

how the hell do i fix fault code 16?
as i drove here today, the orange light stayed on for 5 minutes without going off, when i tried to accelerate, it had no problem, but i did feel some engine pinking going on.... im shit scared about driving home tonight as i know your not meant to drive if the light stays on, the strange thing is that on way home last night, it didnt come on once

Kneepad · « **Reply #26 on:** 26 December 2010, 21:54:22 »

Your problem:

16 Knock Signal Circuit 1

This sensor detects pinking, sends a signal to the ECU which then adjusts the ignition timing to compensate.
The sensor are known to be very reliable and most faults related to this are usually found to be damaged wiring on the sensor.
Have you had any work done on the car recently?

No need to be scared. You can safely drive the car but you will want to investigate the fault. It could simply be the fuel you have used.

Wayne · « **Reply #27 on:** 26 December 2010, 22:00:11 »

i drove the car again tonight, at the moment im driving 50 miles per day in total, orange light came on again, i read somewhere that the alternator might be too blame, or is the error code 16 meaning exactly this, i have noticed my lights have become dinner
(see a previous post of mine)
as far as fuel goes, i always get it from Tescos or Sainsburys in Cowley in Oxford, i havent had any work done for about 3 years, apart from regular 6 monthly services.........

if you had charging problems then the RED charge light would be on. The orange EML light is flashing a knock sensor fault, sod all to do with charging, or lack of.

Wayne - check the wiring for signs of physical damage between the cable tray across front of cambelt cover down to behind alternator - its a thin coax, much like a thin mic cable.

Usual place is its rubbed aux belt, or got trapped somewhere during work being down.

The cable tray across the front of the cambelt cover, check that first, follow it down to the alternator. You don't need to jack the car up...
