Title: EVAP emissions control fault - Updated
Post by: Nasir on October 13, 2011, 10:47:45 pm
Following on from this thread: http://www.mk5golfgti.co.uk/forum/index.php/topic,35998.0.html

These are the fault codes that were found on the car. I've looked them up on Ross tech but are they linked?

I would say possible that there all related? Looks like the recirc dv has give up the ghost or its on its way out, get it changed clear the faults and keep an eye on the first fault if it persists have cylinder 1 pressure tested?

First up, thanks for all your help guys, for me it is invaluable, particularly as none of that stuff makes any sense at all to me!

Darren, are you suggesting an upgrade to the Revision D diverter valve?
Title: Re: Fault codes on 2006 GTI
Post by: andrewparker on October 14, 2011, 09:04:47 am
Oh, and just to provide a few more details, prior to the warning the light and following it coming on the car has felt absolutely fine. Since Nasir cleared the warning light I have done about 30 miles and it has not returned.
Title: Re: Fault codes on 2006 GTI
Post by: mortygttdi on October 14, 2011, 02:39:28 pm
If its on the ED30 cannot you not take it out and check it? I'm sure its a remote DV i.e easier to get to I presume.

There is air escaping from somewhere and that's the most likely place other than intercooler pipes.

Darren
Title: Re: Fault codes on 2006 GTI
Post by: andrewparker on October 14, 2011, 03:03:46 pm
I'm not lucky enough to have an Ed30 dude! I guess it's worth changing anyway and I can do it myself.

The warning light still hasn't came on again however I keep on thinking it feels a bit breathless on part throttle, but that might just because I'm being hyper sensitive knowing that something is wrong.
Title: Re: Fault codes on 2006 GTI
Post by: mortygttdi on October 14, 2011, 04:16:49 pm
Sorry don't know where I got Ed30 from, early morning thought malfunction :signLOL: any way if it feels iffy then change it anyway mate you'll probably notice the difference straight away has the power will have been ebbing away ever so slightly over time has the DV breaks down.

So apparently the N80 Solenoid Valve is at fault. Does this sound accurate, and is it easy to replace?

Evaporative Emission (EVAP)
Canister Purge Regulator
Valve N80

This shows the layout - not sure how easy to change (P10)

Post by: andrewparker on October 31, 2011, 08:53:01 am
This problem is really starting to p*ss me off now. Paid over £100 to have the N80 Solenoid Valve changed on Friday and the warning light has popped back on the dash.

Where do I stand with something like this if they've replaced a part that wasn't at fault?
Title: Re: Fault codes on 2006 GTI
Post by: andrewparker on October 31, 2011, 09:08:17 am
Just another question, the Boost Pressure Control Valve (N249), this is what is otherwise known as the diverter valve right?

Yep that is the diverter valve
Title: Re: Fault codes on 2006 GTI
Post by: mortygttdi on October 31, 2011, 02:59:06 pm
I don't want to sound rude but I told you in the top post Ive seen this quite a few times and the Diverter Valve should have been your first port of call and probably cheaper.

When the DV breaks up it lets air past the valve where it shouldn't and this is why your getting your evap emissions fault, the bank 1 could just be a spark plug thats not gapped properly.

That does sound arrogant SORRY Andrew :signLOL:

Darren
Title: Re: Fault codes on 2006 GTI
Post by: andrewparker on October 31, 2011, 03:12:31 pm
Hey, it doesn't sound arrogant at all Darren. I'm just not too hands on with engine stuff and decided to trust the garage rather than try and fix it myself. My fault I guess.

Just gutted now that I've paid £100 for a fix that wasn't needed, and now it will be more money if it is the DV. :fighting:

No, I'm sure I can manage it. It's back with them on Wednesday so we'll see what they say. If they say it's anything but the DV then I'll be very skeptical. If they do suggest the DV then I think I'm entitled to them doing the labour gratis.

And how right you were. They had the car for an hour to day and now claim they need to for another half day.

I asked if they had checked the diverter valve and this was their response - "when you say the diverter valve do you want to show me what you mean"

I proceeded to show them where it was and they said it might be at the front of the engine. I said that only happened with the K04 cars.

Load of bollocks.

I've ordered a new DV, so hopefully I'll fit that at the weekend. Hoping the warning light won't come on between then and now.

It was the first time I've used an independent garage. I've always taken it to VW Huddersfield and never had any problems.

Getting really frustrating now.

So far I've had the N80 Solenoid Valve replaced, and the N249 Diverter Valve replaced. Sitting in traffic this morning at idle and the light has came back on, probably 10 miles after changing the DV and having the system reset. Again, no noticeable degradation in performance and fuel economy.

have you had the coil packs replaced? and the plugs ?
Title: Re: Fault codes on 2006 GTI
Post by: andrewparker on November 14, 2011, 10:54:49 am
Yep, coil packs have been done.

If it turns out to be the spark plugs I'll go mad. I specifically asked when it was in for it's major service at the end of July to change them, but they argued that they didn't advise they were changed. This is bearing in mind that the car has now done 46k miles. Surely it would have been far easier when they replaced the coil packs anyway!

The above are the logs I took today, I couldn't find the block for the MAF.

I noticed that the revs stuttered downward when you revved it gently. So if you rev it to 2000RPM it comes down slowly, sticks at 1400RPM then comes down again. The engine was revving to 900RPM, once I cleared the fault it went lower to 800RPM.

Can you carry out a basic setting for the EVAP system?

I meant a link to the actual fault code that the car has thrown up. I'm pretty sure it was this one - http://wiki.ross-tech.com/wiki/index.php/16825/P0441/001089 - but I can't be sure.

Andrew I think I know what you're fault is. Have a read here http://www.mk5golfgti.co.uk/forum/index.php/topic,18819.0.html

From what you told me about filling up at Tesco, this makes sense. I hope this leads you to solving the problem :happy2:

Ahh, that's really interesting. I did read another post (this one - http://www.mk5golfgti.co.uk/forum/index.php/topic,37012.0.html) where the canister was to blame. It will be interesting to see if it solves their problem.

I've just checked the hoses on my car and everything looks good. I'm guessing that part is pretty easy to fit too (famous last words!).
Title: Re: EVAP emissions control fault *UPDATED*
Post by: andrewparker on January 27, 2012, 12:55:27 pm
Well after many weeks it appears this problem is finally fixed.

I resorted to dropping my car off at VW Huddersfield and telling them I didn't want it back until it was resolved!

Following replacing the DV, N80 Solenoid Valve, charcoal canister and PCV I was still having issues with the Exhaust System Warning light, a sticking throttle, and rising revs at idle.

It turned out that when the PCV was replaced they didn't change the breather pipe, which had actually split. There was also another hose going into the vacuum valve that was split, so quite a few air leaks. The replacement charcoal canister was also deemed to be faulty, so that was replaced again.

Now I have my car back the differences are unbelievable. I never thought the performance had been effected, but I was wrong. Fuel economy is up, and the car feels very quick again.
