heres what i got on vag-com

VCDS-Lite Version: Release 1.1
Friday, 26 November 2010, 22:39:53.
Control Module Part Number: 06A 906 018 CL
  Component and/or Version: 1,8l R4/5V  MOTR HS V02
           Software Coding: 04000
            Work Shop Code: WSC 00028
                      VCID: 6EAF4DBB3999
1 Fault Found:
16518 -  Oxygen (Lambda) Sensor B1 S1: No Activity

so does this mean new lambda sensor, would this cause the trouble i described earlier?

If it has been sat around it might be the old petrol, put some fresh in and some injector cleaner and give it a good run.

if you want to be extra certain that its the lambda, check the resistance with a multimeter. and you should have your answer, you can get the ohms readings from auto data or tolerance, i can post them if needed

can you tell me how to check and what setting to use on the multi metre, and what the reading should be??? please... cheers buddy

yer no probz, sorry for the long delay been in work all day..

multimeter setting needs to be on ohms to read the resistance, (the symbol that looks like an upside down horse shoe)

unplug the connector,, and u should have four  terminals, put your multimeter across terminals 1 & 2, at 20 degrees C it should read between 1 to 5 ohms.

if you wanted to check voltage, multimeter across terminals 1 & 2 again and you should have battery voltage

hope this helps you out fella

nice one buddy... when i unplug connector do i need the engine running? and do i check the loom side of the connectors? also you say " at 20 degrees c what temp is this in relation to?
cheers for all your help mate

its ambient temp mate, its just and indication, to check resistance u dont need no power going through the sensor. to check voltage just turn the ignition on..
