Facts and Figures But Whats The Cause

[basscrazy]

Ok ive failed mot originally them saying the wiring for lambdas was wrong


Ive learnt in the past to get all my facts and figures in before going into things and i have done so


Its been looked at by a sparky and hes said the wiring is not the cause and the garages who diagnosed it were wrong
My cats have been tested and are working fine (they had only done 6k anyhow)
Ecu is Fine
But These are the proper stats (will help Ard as well buddy)
Co = 5.00
Hc or Mc (i cant read his dam writing) 203
co2 = 11.71
02 = 0.40
Lamda = 0.874

Also the wiring chap when scanned my car etc said it was showing the error
Exhaust supercharger recirculatnig valve
They have said since this is not supercharged it could relate to a part labeled as this

So theres my facts and figures
New maf fitted new lambdas cats good etc

Cheers Guys

natural idle? fast idle? can't you just scan the print-out and post it here?

natural idle 0.02 co and 5.00 fast i updated first post with all he wrote down

 

[basscrazy]

right below are full details of what i got told

Also someone has said the supercharger valve is the dump valve?

It's running well rich at idle.

Have you had it scanned with VAG-COM? It gives a better idea of what's going on and usually points to suspect parts by name.

It could be that the DV is broken but that's a 2 minute test and I don't see it making the car run rich.

A faulty water temp sensor might or a massive air leak. Have a look on Ross-Techs web site about fuel trims.

yea it says exhaust supercharger recirc valve which is dump valve as its 50/50 atmospheric

Other then that theve said temp sensor is working and the cat and lambdas are both new and the maf is new

where is it running rich at idle tho?

Mot standards are

Normal idle 450-1500rpm
CO no more than 0.5%


im 0.2-0.3 on normal idle

or am i missing something lol
