Title: Check engine light disabled.. Illegal tampering?? UPDATE IT WAS TAMPERED PAGE 2
Post by: ruffrydaz on January 24, 2011, 12:22:40 pm
Sorry this isn't a gti but my gt tdi 2.0..
The emissions workshop message has appeared on the mfd but the engine light should also be on.
I scanned it and this was the intake flap seizing.
I thought mine was just different but when I turn the key in the ignition sequence most lights come on but the engine light doesn't come on at all.
I think either
A) it has Been driving with the light on for ages till it burnt out.
B) bought it from a dodgy dealer?
Any ideas please
Thanks

The indicator lamps on the Mk5 are all LED. They have lifespans in the region of 10,000+ hours. Pretty much no possibility for it to be "burnt out" (that's not how LEDs work) but it's possible it never worked in the first place (but then again, I imagine factory quality control would have picked up a thing like that).

Thanks for the reply
What's the best way to go from here.
I will post a pic soon of my startup sequence to make sure there are no other lights disabled

Someone needs to plug vagcom in to check if the led works you can activate it to see if the led works. But from then I'm not sure it does need to work though by law your right there. There could be a problem with te circuit board in the cluster. There are a few boffins on here who will sort you out on this...

Post by: ruffrydaz on January 24, 2011, 12:50:15 pm
Well I bought it with emissions workshop message so I'm pretty sure someone Took the bulb out so only the message comes on and not the light.
I have vagcom btw, any idea how to check the LEDs via vagcom?
Title: Re: Check engine light disabled.. Illegal tampering??
Post by: cmdrfire on January 24, 2011, 12:55:53 pm
Again, can't take the "bulb" out - the LED will be soldered to the circuit board.

x2 on the VCDS but best wait for a vagcom experte to show up here and tell you what to do...

IIRC select the instrument cluster in VCDS - you will then be able to run the self test, this checked all LED's and does a sweep test of the dials.

Any ideas how to do this. Cant seem to find it in vcds
Title: Re: Check engine light disabled.. Illegal tampering?? * PICS ADDED
Post by: ruffrydaz on January 24, 2011, 06:14:57 pm
Ok im really annoyed now i think it has been tampered with..
Here is a pic all the lights come on and go off as expected except the CEL light.
Im sure this has been tampered with or a big big co incidence
Can i check the LED on vagcom or do i have to remove the cluster to check
Im sure the led or wiring has been fiddled with
Thanks guys

Im not sure you could really and i think it would be a lot of effort to have it tampered with to stop the light coming on... and unless there is a hugely expensive item gone wrong one the car for the light to be on then it wouldn't be worth having it tampered with.... so you need someone on here who knows if the led for it can be turned off but i can't see that. i think its more likely that its just a huge coincidence but there is a problem with the cluster it can happen...

When you say you had a fault code did it say MIL ON??  Not all fault codes will illuminate the CEL.

16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 001 - Upper Limit Exceeded - MIL ON

I thought the glow plug light on a diesel was the 'check engine' light of a petrol? 
Title: Re: Check engine light disabled.. Illegal tampering??
Post by: ruffrydaz on January 24, 2011, 09:04:34 pm
ub7rm:
no there is check engine for diesel and EPC for petrol
The engine light should be under the glow plug light and above the red steering mechanism

vRStu: I know but the engine light doesnt even come on at startup
Title: Re: Check engine light disabled.. Illegal tampering??
Post by: ruffrydaz on March 16, 2011, 01:00:59 am
Ok. When i bought the car the exhaust emission light was on in VAGCOM ONLY because of the egr and imf flap.
But the light doesnt work in reality.
Im gonna check it once and for all tomorrow. im sure it had some  black tape over it or something
When i remove the cluster cover can i just lift the dials off the board to reveal the leds without removing the needles?
thanks

VCDS > Instrument Cluster > Output Tests

Thats how you test the cluster
Title: Re: Check engine light disabled.. Illegal tampering??
Post by: ruffrydaz on March 16, 2011, 09:32:26 am
Yeah tested it. It doesn't come on in output tests

I asked a mate in the trade about this he said simples to disable any particular led to remove an "expensive" warning light, probably not a good idea to tell everyone on an open forum but it is a 2 second job with the cluster out and hey presto your led doesn't function anymore...................

good luck but sounds like someone had done this prior to selling it!!

Since you have scanned this with VCDS and the only error you have was fixed by the flap and so there is clearly no reason why someone would have disabled the LED I'm not so sure why you are worrying.  Most things are displayed on the screen as well as the light and you obviously have vagcom to check for error codes.

Highline TDI clusters are also reletively cheap on ebay so if it worries you maybe buy a replacement and get it installed.

I agree it is possible if you are determined and it might be worth the OP removing the cluster to check for signs of opening.

This should help you with the removal and dismantling...

Rich the intake flap triggers the light so what a co incidence that that light doesnt work. Im not worrying, just wondering if they did.
when i pull the cluster out it wont fit through that gap and it wont come out even when the steering is low- any ideas

ALSO
The rev counter needle isnt on ZERO like the other needles (as seen in the picture in the first page) and you need to remove the needle to remove the dial.

Ok just as i thought ill let the pics do the talking
(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fi56.tinypic.com%2F1yvfpd.jpg&hash=46bd7605ae9c863abea0f07ed7f28138c56c7043)

Tissue covering the light

The culprit

Car with the light on

So basically there are two faults triggering the light. Imf and egr. I changed intake manifold flap.
Now the only error is egr ill change that soon too.

Should i speak the to private dealer i bought it off. Its been 3 months since i bought it
Its not a major fault i dont know why they would do it. I know its not major but it still doesnt feel good spending money and finding this out.

Post by: Richn83 on March 16, 2011, 01:50:46 pm
That's terrible!  I imagine its not a nice experience, surely the fault was still showing up in the display and via VCDS even though the bulb was covered?  Glad you got to the bottom of it I would be tempted to have a word with them see if they will provide any good will but I guess it will be impossible to tell if its them or whoever sold it too them that made that helpful modification!

Sadly I doubt you can prove who put it there, could have been the person the 'private dealer'* bought it off?

I'd still report it to trading standards though, just in case there's a load of people making similar complaints against said chap and it'll support a case.

*Can you define this? Someone selling from their house, are they VAT registered??

Post by: ruffrydaz on March 16, 2011, 01:57:36 pm

Oh well its not a major fault but just doesnt feel good
Yeah emissions workshop came up but not the light
I bought it from these guys
http://www.bvb-burtonontrent.co.uk/336294/index.htm
Maybe not them, could be the person who traded it in, who knows.
thanks for everything guys

i did this on my last car, after i disabled the imobiliser the light wouldnt stop flashing, so some foam got put down the hole  :signLOL:

Thats shocking that is. Reminds me of a customer I had in on their polo, where someone had filled the ABS light hole up so you couldnt see the ABS wasnt working  :fighting:

It looks like a fully fledged independent and I would certainly take it up with them you havent really got anything to loose even if they offer to do the corrective work at cost.  If they wont help then I would take the car else where in case their mechs solution is another piece of tissue!  :scared:

Post by: E30Dom on March 16, 2011, 03:22:15 pm
That's shocking! But glad you got it sorted... so is the led still working?

I'd say you haven;t really got any proof whether it was dealer or person who sold to dealer, but still would be worth mentioning to TS...
Title: Re: Check engine light disabled.. Illegal tampering?? UPDATE IT WAS TAMPERED PAGE 2
Post by: ruffrydaz on March 16, 2011, 03:26:55 pm
Yeah the LED works fine its just the tissue over it.
It was a stupid thing to do because the message comes on the mfd anyway and thats what made me think it should have the light on too.
Anyway 180 pounds for the intake flap
Need another 80 pounds for the egr
Nothing major will mention it to them and see what they say

My guess is that the previous owner disabled the EGR. Blocked it of or something to that effect.
A blocked EGR shows up as Check Enginge.

It's common to tamper with the EGR as it is the spawn of satan. Disabling EGR gives you a cleaner engine, less sooth, better economy and more.
Research this yourself.

You might want to be sure why the EGR is in error, but I would leave EGR disabled if it was me. A good tuner should be able to make the warning not appear for EGR only.

Oh and hi. My first post and all..
Title: Re: Check engine light disabled.. Illegal tampering?? UPDATE IT WAS TAMPERED PAGE 2
Post by: ruffrydaz on March 16, 2011, 03:38:19 pm
hi mck welcome!
Its not that
The egr isnt opening because the diaphram is screwed
And the intake flap was fudged too and was getting stuck

as long as this helps someone in the future im happy
thanks guys

The garage that sold it to you should have confirmed it all worked before selling it shouldn't they? I would be asking them about their "PDI" actions and speaking to TS about the whole thing. Make some noise and challenge them.

Good luck,

John
