At LeMans with dash all lit up!!

GregorFuk · 13-06-2015, 10:25 AM

So. Travelled down to Le Mans yesterday and about 120miles from our final destination I start getting warning lights on the dash.

The center light and light on the right came on first. And they've caused me to lose DSC etc. No biggie I thought. They are also going on and
Off intermittently.

Then, the yellow engine warning light came on. I'm a bit concerned about this one as I have a big drive home. The car still drives perfectly, and the engine runs fine. What are people thoughts on driving home (Scotland) like this?

Looks like Wheel speed sensor (ABS).As I had this.Cant seem to remember if the engine light was on though

Engine light came on later. Almost seems like a separate issue. Still getting gears with now issues.

I could be wrong but this to me sounds very much like the beginning of the end of your alternator. I've experience the very same few year ago. Lights coming on one after the other while driving with no obvious ill effects to the drivability or engine.
If you can get a hold of a hand held voltmeter I'd check the alternator output while the car is idling with a load on (lights, A/C, wipers, etc.) if it reads below 13V and doesn't rise when the engine is revved that'll be your most likely problem. Also check the voltage of you battery with engine off.

It could be 2 separate issues, the first 2 lights as Bounce has said could be a wheel sensor, no great shakes.
Do you have an after market exhaust? Or cats? The engine light can go on and off if you have.

When my alternator was going I only had the usual red light, it never failed and lasted ages before I took it in for a warranty change.

They shouldn't be anything to worry about.

Famous last words...

Alternator is the shiniest thing in the engine bay. It's not done many miles. Car seems to be running fine so can't be anything too serious.....

I think it's two issues though. Engine and wheel sensor of some sort.

Gregor, as s.mac says, the engine light on the left cluster could be a dodgy O2 sensor on the exhaust system or if you've changed and/or removed the cats for 100 cells etc you will get this indication intermittently.
