Guest dobbo Posted July 5, 2007 Seems I only come around these parts when I need help.. :guiltysmiley: I have an intermittent fault which causes my engine diagnostic light to illuminate, so I bought one of those Draper fault code readers. The instructions say to locate the green 2 pin diagnostic port on the inner wing/relay box/next to expansion tank. I found a 2 pin port on the inner wing but it's not green!? Anyway, the diagnostic reader doesn't work here. So a bit more searching turned up a 2 pin green port over by the airbox: Which looks like it should be the right one: But this wone doesn't work either. So I guess my question is, am I looking in the right place? Mine's a late model K plate with a catalytic converter and (I believe) the later engine management system, hence the diagnostic light. Can anyone help out a moron who doesn't know what he is doing? Thanks! Share this post Link to post Share on other sites
pugpaul 1 Posted July 5, 2007 Have you checked around the battery area? There should be a cream coloured plug hanging around there.....try that....hope it works! Share this post Link to post Share on other sites

Andrwn8304 0 Posted July 6, 2007 I bought one of them code reads a while after spending 2 weeks and a few trips to the dealers who couldnt find the Green Diag plug either, I emailed Draper to ask if it suitable for the Gti's and was told in polite manner because Draper doesnt make them for Gti's as they dont have a Diag Plug fitted to the engine.

Yours is probably pre cat so it won't. The later models (late K reg 1.9 on) will I believe....... Share this post Link to post Share on other sites
simonb 0 Posted July 6, 2007 I think it's only the Motronic fitted cares that have them fitted. Earlier ones don't and so you are wasting your time. Share this post Link to post Share on other sites

Since mine's one of the last GTIs I assumed it would have one, certainly I thought mine was motronic. Share this post Link to post Share on other sites

IIRC the Motronic 205's have a black plastic inlet manifold though but yours might have been swapped for an alloy one by a previous owner for some reason. Graham.
