has come on this afternoon :scared:
Would the faulty Pcv cause this light to come on???
New Pcv arrives tommorow, so if this is caused the light to come on, will it go out when the new valve is fitted?? or is it a dealer then has to remove fault history to get light to go back out.
and most importantly, should i be driving the car if this light is lit???
Thanx chaps for any help
:happy2:
-
I had the same light come a a couple of weeks ago - dealer said it could be anything in the engine that triggered it from the MAP sensor to the exhaust - not very helpful I know but sharing what I was told.
Incidently, while I was getting my WALK fitted, some guy with VAG-COM removed the fault before I could take it to the dealers thinking he was doing me a favour :fighting:
-
Have you plugged the MAF back in?
-
yes m8 i have
-
Don't worry about it Steve. If (as I suspect) it is linked to the faulty PCV or disconnection of the MAF/Airbox then it will be okay to run as normal and just get it checked out when you can via VCDS/VAG-COM and get the error code removed. :happy2:
-
what was the error code that has been produced as a result of the fault, assuming you have had this on VAGCOM. I had a similar problem a few months back and I had to have a new cat fitted. under warranty thank god :sick:
-
Steve hasn't got direct access to VCDS Daz.
I hope it isn't his cat as he's just got a Milly downpipe fitted a while back!
-
ahhh right. didnt want to worry him or nething but everything the dealer tried didnt seem to work so they just replaced my cat and that sorted it, hope all is well :happy2:
-
have got stage 2 map after fitting the down pipe as that will also set the light off
-
Theres a fault code reader built into the bf handset, takes about 30seconds to give the fault code :happy2:

Well I never knew that!

He has stage 2 and that doesn't bring the light on in my experience :wink:

Which needs enabling by Superchips....

Steve,
Missed you call, sorry mate. I think as Hurdy says it will be linked to the leaking PCV. Perhaps ask your friendly dealer to download the code and see what that brings up.
The erratic idle is also a pointer to this.
-
My handset reads faults and has never been enabled by sc :confused:
Plug in, press no rather than following usual process, read faults, then clear them...
-
Not quite related to the PCV other than someone running the car without the airbox on. :surprised:

All cleared and saved. Short test drive didn't show anything further so (touch wood) job done.
So then I coded his Nav and enabled his hidden menu all without any lovin'. :sad1:

i was told you need stage 2+ to stop this with the milltek dp/ cat fitted , cause 2+ cancels the problem which basically your ecu can not detect the cat if its not up to operating temps , so if you do short jorneys after the 8 th one it will bring up the fault light cause thats how the ecu works , thats why i never got the dp/cat and went non res cat back
-
no its taken care of with stage 2 revo :smiley:
-
Just to throw a spanner in the works you can run Milltek downpipe and cat with the standard map without any warning lights. :wink:
-
can u ?
-
can u ?
Oh yes. :wink:
-
did not know that as when i put the DP on mine within 300 miles the light came on, but i did have stage one on the car

Milltek or Blueflame? :smiley:
-
i was told the ecu checks this every 8th cycle and if you dont get the cat to full temp on 8 consectutive jorneys the light will come on ! was nt sure about revo s2 or s2+

Not quite sure where that info came from but irrespective of map my light doesn't come on with a Milltek DP & Cat. :wink:
-
Just arrived back from Mr Hedges. Thanx again mate for looking into the problems so quick.Hope your dinner tastes better then mine does :sick:
Ive been running standard map with full milltek and no warning errors shown up.
My doing with removing the airbox tracing the air leak, and lean idle which i hazard a guess again running with no airbox would make idle more lean as usual drawing too much air rather then set ammount governed by the oem airbox.

I shall edumacate him next time I see him. :laugh:

So when someone goes Revo stage 2+ for example they disable the warning light system? So if you get a faulty lambda sensor, faulty Miltek cat you will never know you have a problem unless at the MOT?

No,
They fix the lambda settings, but the sensors still work. If you get a low setting through the cat being defunct you will eventually get a CEL light on. :smiley:
