I have an 1.6 Skoda Octavia AUV engine.

I put it in threw its NCT test and it would not pass the emissions test because they could not get the car to idle for long enough.

Could any body tell me how to make it idle for it to be tested, I already talked to a SKoda mechanic and he told me, I just had to put the side lights on, but that didnt work, I got the car up to running temperature when I tried it.

Can any one help me, my NCT is on Friday the 24th of august.

you mean it cuts out?

He might mean fast idle, 2500 - 3000rpm. They can be a pain to hold at a steady fast idle, the way to do it is to load up the engine, all the electrical consumers on, steering at full lock and air conditioning on. Unfortunately it's a bit of a compromise as our MOT methods say not to have any load on the engine during an emissions test.

It needs to idle at 2500rpm for the emissions test and it won't idle at that , it just revs up to 4000rpm when you hold down the accelator a bit

faulty throttle position sensor maybe

everything is fine in the car, I will try what fordfan said, but I was talking to a Skoda mechanic today and he said just turn the sidelights on to put an load on the engine and it didnt work

Hi,

Did you find the cause for the throttle control issue?

I am experiencing the same problem and any suggestions on a possible cause would be much appreciated.

Thanks
