l have had a guy contact me desperate to get his car through an MOT because it\'s his daily, and he has failed his exhaust emmisions test by reading 7.65% and HC was 2686, way above legal requirement.
The car is a 1992 K reg and this reading was after fitting a new Lamba sensor.
My question is how do you make the air pump run all the time, as this will apparently bring down the readings.

The air pump will run below 3000 rpm. So just get them to keep a lite foot when doing the hi-idle test. ;)
Failing that get an Apexi fitted.

He needs to tell the tester to run fast idle test at 2500rpm, not 3000rpm. While it\'s being done the guy should stand there to check that the air pump is running. Any MOT tester should find this is perfectly acceptable once it\'s pointed out to them.

Clive, the Air pump relay is in that little row of relays on top of the radiator.
All you need is a little jumper or a little piece of wire, to jumper from the "Live" or power, to the "on" for the relay, I did it for my SVA test.
If this doesnt make sense, I will try and post a diagram later.

Guys,
Just to save you some time on this one. I looked into the possibility of leaving my air pump running during MOT last year and spoke to Pip about it. He said that it brings one figure down but causes another to rise so you still fail. Think it might reduce Hydrocarbons but increase Lambda. Bottom line from Pip is that you either need to get the generous emissions test done or fit a replacement ECU for the test and lean it off.
