Following on from my boost leak thread, I think I have identified the boost leak as a failed diverter valve. I now have a new valve to replace the old one, which should clear one fault.
The other fault code I have is this one:
001089 - EVAP Emission Control Sys: Incorrect Flow
P0441 - 002 - Lower Limit Exceeded - MIL ON
Freeze Frame:
Fault Status: 11100010
Fault Priority: 0
Fault Frequency: 15
Mileage: 101064 km
Time Indication: 0
Date: 2000.00.00
Time: 13:39:07
Freeze Frame:
RPM: 827 /min
Load: 21.6 %
Speed: 0.0 km/h
Temperature: 72.0°C
Temperature: 12.0°C
Absolute Pres.: 1000.0 mbar
Voltage: 14.224 V
Ross-tech explain it here:

But what is this system and where do I start looking?
Could this be caused by the boost leak from faulty diverter valve? This error I have had for a while but the boost leak is a recent one.
I don't really know where to start with this one.
Bring back the good old days. I remember rebuilding my sisters Punto engine after the cylinder head went and I pulled out every single component from the head and completely rebuilt it, re-grinding the valves and everything. I miss those days.... It's all bloody electronics now :sad1:

I'm not familiar with all the Ross/VCDS codes etc but can tell you that a failed DV (Diverter Valve) would create a boost leak. The earlier GTI's were quite prone to ripping the plastic diaphram on the oem DV if the car was tuned. A very random fault but lost of cases.
VW/VAG revised the DV lost of times and although mine didn't rip I got a Forge DV as a precautionary measure.
I understand that the current VAG DV is up to the job but someone else will have to confirm this.
-
Thanks for teh replay mate, but I have actually already established that part :wink:
I have a new dv to replace the old one as the is what is causing the boost leak. Its the other fault (that is longer running) that I now need to solve :happy2:
-
i think you need to check your PCV diaphram situated on the camcover, a good replacement is the BSH pcv fix W/O catch can, :happy2:

rubber, not plastic, ever heard of a plastic condom?? :P :jumping: :star:

Thanks mate, I'll take a look in the morning
-
That fault is nothing to do with the DV or the PCV
I have had it a couple of times (including with the BSH catch can)
It is a random fault and according to Skoda it's to do with the Charcoal canister.
IIRC they wanted some stupid amount to replace the canister and i said ram it as the car drives normally and it's not a constant fault.
If you are getting it permanently i would take it VW and get them to tell you exactly what it is that is wrong.

I have had this randomly and it clears usually, i have seen it on two other cars also, non of these have any problems with power etc etc, so i would be tempted to leave it, if you must do it then its a canister change along with some of the pipework and a small valve iirc
-

....Plastic = a synthetic material made from a wide range of organic polymers which can be moulded into shape while soft and then set into either a rigid or slightly elastic form.

I know :smiley:, but it is made of rubber, i have one right here in front of me. Sorry RR, it wasn't meant in any other way than just a little laugh.
And i stand corrected regarding the reason for this error code :notworthy:

No problem, Danish :drinking: :laugh:
Why do you have one right in front of you? You're not thinking of using it as a contraceptive are you? :evilgrin:

Already tried that and VW just cleared it and sent me on my way. The car drives fine with the light on, but I don't like looking at the light!!

Same here. Thanks for the suggestion, I will probebly pull the canister and associated pipework to make sure it's all clear when I replace the dv tomorrow.

The missus might find it stimulating, about double the size of what she's used to :grin:

oh dear... :popcornsoda:
-
Mater does the fault put the engine light on? I know on the american tfsi's if the petrol cap is loose or faulty it can create that fault with a light though.

No mate. I've only seen it about 4 times in the 3 years i've had the car.
If it becomes more frequent i will get the Charcoal Canister replaced

Where's this "Charcoal Canister"?

Cheers RR - what does this thing do? Is it something that needs to be replaced/serviced after a certain number of miles?
I must admit I have never seen it in my car.
-
^^^^
I hope you have seen it! You won't get through UK MOT without it.
It filters fuel vapours I think. They don't need to have them in the U S of A.
-
If you are getting the EVAP fault then check this hasn't happened.

This is why I was getting it and since fixing that it hasn't been back touch wood.
-
A friend of mine had one on his car go and it killed his mpg and the engine ran really rough. Since replacing it his engine is back to normal. I think he paid about £80 or there abouts for a new cannister.
-
Check the breather pipe first as that is about £9 to replace. A charcoal canister is about £95
-
I personally don't think it will have any effect. I had to have mine changed and didn't notice any difference in MPG when it was faulty.
-
I never noticed any difference with MPG either when I replaced the pipe.
-
I never noticed any poor running or mpg change when I had the evap fault code but the canister did fix the code. A bad PCV seems to cause a lot of running problems.
