hi all
just making a short journey tonight and the emission control warning light came on.
i only had the car serviced a month ago, its a 1.9 tdi 130 bhp a4

any ideas on the cause and solution

thanks in advance

you need to pull the fault codes, if it came on and stayed on.

If it was on for a second or two while engine was cold I would not worry, this is not uncommon with modern engines

hi lonky
thanks for the reply
i had only travelled about a mile when it came on, it stayed on till i got home which is about another 2 miles.
i have to drive 20 miles to work tomorrow on the motorway will it be safe to do so?

Driving with light on perminantly is not recommended, if mixture is wrong, damage to the cat can result. Damage to the engine other than this is unlikley.

would see if light stays on when you next use it. If so would get it to garage ASAP

The less miles the better.

Once the unit is plugged into a diagnostics PC then the situation will be much clearer

light went out after 30 seconds on my way to the garage
drove to and from work (40 miles) no light
went out on short journey switch on my windcreen blower and it has come back on!
