im back 2 a golf again after my jap phase... lol... cant beat the german built cars... right ive just bought a mk4 1.8 20v gti non-turbo AGN, its been stood for 2-3 months prior to me buying it now the problem im having is when driving at low revs it sort of feels like the revs are fluctuating and the car will bouce/ chug if you know what i mean!!! and it drinks fuel big time... has anone got any ideas as to what it may or is wrong? cheers guys
-
need to get it scanned for faults mate might be MAF sensor..
-
niceone buddy... do you mean pluged into vag-com? or diagnostics? or either?
-
both the same buddy.. yer get a friend or a garage to get it coded for fault codes.. come back list them here and we will help with what to replace :smiley:
-
niceone... cheers buddy

heres what i got on vag-com
VCDS-Lite Version: Release 1.1

1 Fault Found:
16518 - Oxygen (Lambda) Sensor B1 S1: No Activity
P0134 - 35-00 - -
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.

it had no petrol in it when i got it and ive done a whole tank in it since... and ive drove it like i stole it since i got it... lol... why would it be telling me the lambda's not working?
-
can anyone shed some light on the vag-com code?
-
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..

cheers buddy you've been a great help...
