05 LX 1.8 TDCi - Red 'cog' warning light.

Hi.

Driving round the motorway roundabout before a 250-odd mile journey last weekend and this light illuminated on my dash. Red cog with an exclamation mark in the middle of it.

Oh dear.

I didn't stop - because I was unsure as to whether the car would go again if I did. Drove it straight to a local Ford garage. There was no loss of power. No odd noises. Nothing unusual - aside from the light.

After stopping and switching the engine off the car started again first time - no warning light.

The service dept. was on half day, so I asked a salesman about it.

We chatted, he noted that sometimes on a diesel these lights come on if a sensor detects something a bit funny. But if they go off again and the car drives normally, it's nothing to worry about.

So I set off on my merry way. Did the 250 miles on the Saturday. 380 on Monday. And then 250 miles back on Wednesday. Car running (fingers crossed) as good as ever.

So to the question.. What causes this?

Thanks.

The red cog as you call it on mine is the ambient temperature sensor showing freezng conditions...are you sure it doesnt look like a snow particle...they look like cogs!

I have just look in my Manuel and it is a:-

"Engine Systems Fault Warning light"

Quoted from the Manuel

"If it illuminates when driving, it indicates a malfunction of the engine and powertrain system. Stop the vehicle as soon as safety as possible and switch of the engine immediately. Have the engine checked by a expert."

I didn't say engine management light, I said engine systems warning light. I too have the 2.0 TDCi and I know what it cog means. Read Grahams post or even your owners manual for more info.
