Defcon5 Posted November 18, 2010 Report Share Posted November 18, 2010 What makes you think you dont have one? Quote Link to comment Share on other sites More sharing options...
si_leeds Posted November 18, 2010 Report Share Posted November 18, 2010 probably the same reason i dont think i have, when i first turn the ignition on in all my previous cars the ecu light has come on with the stratup lights and then gone off, on my arosa it never has done....

VW_LUPO 1 Posted November 18, 2010 Report Share Posted November 18, 2010 lupo has epc. electronic power control or something. might be same as arosa Quote Link to comment Share on other sites More sharing options...
budd Posted November 23, 2010 Author Report Share Posted November 23, 2010 Don't have a epc light as it is throttle cable. But surely I should have a engine managment light? Quote Link to comment Share on other sites More sharing options...
VW_LUPO 1 Posted November 24, 2010 Report Share Posted November 24, 2010 So why does mine have one? Quote Link to comment Share on other sites More sharing options...
Silver! Posted November 24, 2010 Report Share Posted November 24, 2010 My 1.0MPi Arosa 2002 had one. Quote Link to comment Share on other sites More sharing options...

kabman Posted January 22, 2011 Report Share Posted January 22, 2011 Emission lightI have a '99 1.4E Lupo and the engine management light doesn't come on when I turn on the ignition. I suspected the previous owner had nobbled it to hide a problem but can't see any signs that the instruments have been tampered with or any wiring has been cut.Is it possible that early cars didn't have it as they're not OBDII compliant? One of the (many) requirements of OBDII is a bulb check at key-on.I know my car doesn't have an EPC light as it's a cable throttle (AHW engine) and it has the diagnostic plug behind the lower cubby not behind the ashtray.So....those of you with no light, are your cars 1999/2000?Anyone with a definative answer to this? It would put my suspicious mind at rest Quote Link to comment Share on other sites More sharing options...

It would put my suspicious mind at rest My 2000 1.4S had a AHW engine, and cable throttle body and that definitely had an EPC light when I turned the ignition light on. It also had OBDII as far as I'm aware as the connector looked identical to the one that I have in my GTI Edited January 22, 2011 by NOCK Quote Link to comment Share on other sites More sharing options...
budd Posted January 23, 2011 Author Report Share Posted January 23, 2011 I read that maybe the bulbs could have burned out where they have been egnored. I rang up vw but they had no idea would a vag com bring up if the bulb has gone? Quote Link to comment Share on other sites More sharing options...
kabman Posted January 24, 2011 Report Share Posted January 24, 2011 I read that maybe the bulbs could have burned out where they have been egnored. I rang up vw but they had no idea would a vag com bring up if the bulb has gone?They're surface mount LEDs so can't be removed without cutting them off the PCB and it's very unlikely they would burn out. I've checked the LEDs are there on my car. As far as I can tell, the 32-pin green connector on the back of the instrument pack doesn't have a wire for the EPC light but I haven't figured out the wiring for the engine management light.Anyone have a curcuit diagram covering the instrument pack for a pre-2001 car? The one I have is for Dec 2000 on. Quote Link to comment Share on other sites More sharing options...
budd Posted January 26, 2011 Author Report Share Posted January 26, 2011 Is there any sort of relay fuse for the enine management light? Quote Link to comment Share on other sites More sharing options...
budd Posted January 26, 2011 Author Report Share Posted January 26, 2011 Please let me know if you find out anything I'm crap with the electrical side of things. Does ur car have any trouble connecting to a scanner Quote Link to comment Share on other sites More sharing options...
kabman Posted January 28, 2011 Report Share Posted January 28, 2011 Please let me know if you find out anything I'm crap with the electrical side of things. Does ur car have any trouble connecting to a scannerI have a generic ScanTool at work but haven't tried yet. If that fails I will borrow a VAG tool and try that.I don't know if there are any fuses or relays which is why I'm keen to get hold of a circuit diagram. I wouldn't expect there to be though. It is likely the LED shares a common power supply with other bits of the instrument pack and the ground is controlled by the ECU. I'll test this when I get time.

kabman Posted March 5, 2011 Report Share Posted March 5, 2011 (edited) Well, the Scantool didn't work on my car but that's not too surprising. VCDS/VAGcom showed no fault codes on any module, including the instrument pack. I ran the 'output test' on the instruments and the MIL light is not tested so I can only conclude that it's not active on my car. I expect the same's true of all pre-2000 cars. My next job is to get hold of the right circuit diagram, then I'll know for sure. The EPC light is definitely not active on cars with a cable throttle body.

veedubs! Posted April 3, 2011 Report Share Posted April 3, 2011 did eny one find out what thats was? mine is a 2000 x reg sport and mine doesnt have one on! Quote Link to comment Share on other sites More sharing options...
sat1983 Posted April 3, 2011 Report Share Posted April 3, 2011 I have the same problem- but it's not the EPC light not coming on it's the airbag light. No signs of tampering with the clocks either. VCDS shows no fault either with bulb. Mystery! Quote Link to comment Share on other sites More sharing options...
