Evening all,

Right...

Driving my car to Milton Keynes today, I noticed the orange engine management light is on, on the dash.

I recently (about 6/7 weeks ago) put a Janspeed manifold & sports cat on.
Since then i've probably covered a good 1000+ miles.
Could it be that the engine management system has only just noticed the change?
Everything else seems to be fine.
There is no loss of power, no change in the running of the car.
All the levels under the bonnet (coolant, oil, etc.) are nice & high.

I know the solution is to get the override from PTP.
I know that the light turns itself off after 150+ miles once it's installed.
I know that it shouldn't affect the outcome of an MOT.
But it's ****ing annoying... little orange light!

Help is appreciated guys!

Oh yeah... there also seems to be a loud whirring noise from under the bonnet when sitting at idle.
Could be during movement too, but I wouldn't know as i'm inside the car.
My sister's boyfriend reckons this sounds like the fan working overtime.
Any ideas on that?

Going away on holiday tomorrow morning so would be nice to put my mind at rest!

Thanks guys!

As for the light, i don't know the solution but this isn't the only car with the problem, a lot of vauxhalls get this.

It's on from the moment I start the engine (0mph)+.
I'm almost certain from reading other posts (searching!) that it's due to the exhaust system.
I just want some confirmation.

Yeah I have a diag kit and it's worth the money!! I'd recommend just getting the error codes off and resetting the lights, driving a bit and seeing what comes back up.

Saves £40 at the garage!

It is probably the fact you have now got the Janspeed sports cat ssystem. This changes the emissions so that they are only just within the legal limit and on some cars this is low (or should I say high) enough that it causes the MIL (Malfunction Indicator Light) to illuminate. Janspeed themselves recognise this problem and sell an MIL eliminator. A few other people sell them as well such as PTP and I think there was a member on here selling them as well. You may need to fit one of them to put the light out

As above, had the very same problem, you need a MIL eliminator, i had mine wired in wrong, the light came on after a few trips, re-wired it, and the light went straight away.

Mate, when i had my ZR that stupid orange light came on, i know what you mean about it being annoying!

My dad put it through the diagnostics machine and just reset/cleared it but i came back again, turned out it was the o2 censor, so could well be that.

Alright mate? I have the same noise coming from mine. Sorts sounds like its coming from through the dash vents. Goes away when i press the clutch in.
Did you find out what it was yet?
