Two major issues:

The images included are much too large, and obviously scans of copyrighted material. I intentionally "broke" the links for now.
The bottom says the information was taken from a VW manual. That may constitute copyright violations as well, though I can't verify that online.

The copywritten images have been removed and a tag has been added for the image that is of my own personal vehicle that i have provided for reference. Pcressman 06:03, 9 March 2007 (UTC)[reply]

That's good. But what about the text of the article? Is it copied directly from the manuals you cited, or did you rewrite it in your own words? If you rewrote it, then we're fine; otherwise, it's a copyright violation. Realkyhick 06:26, 9 March 2007 (UTC)[reply]

Information in this article has been rewritten and not copied "word for word". Pcressman 06:39, 9 March 2007 (UTC)[reply]

Fair use rationale for Image:Dgfisysmap1.jpg

Image:Dgfisysmap1.jpg is being used on this article. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.

Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Wikipedia:Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.

If there is other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page. Note that any fair use images uploaded after 4 May, 2006, and lacking such an explanation will be deleted one week after they have been uploaded, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you. BetacommandBot 04:47, 16 September 2007 (UTC)[reply]

Bad earth fault... can be pretty extreme.

I suffered the exact problem described in one of the latter sections, where the earth strap on the gearbox came loose after presumably not being properly tightened up following some overhaul work... thus, blown ECU (luckily I actually happened (!) to have a spare...), and injector locked at max output any time the ignition was switched on.

"Flooding the engine" doesn't even cover it. Rather than the usual sense of that phrase, where there's just an excessively rich fuel mix in the cylinder so it won't ignite, it proceeded to try and empty the fuel tank into the inlet manifold... and from there, through an open inlet valve, into the cylinders, and eventually past the piston rings and into the sump. Luckily, the mode of failure was such that it also wouldn't run the starter, and between discovering it was dead and realising the cause of the fault (during which the ignition was left turned on for several minutes...) it was left to sit for about 48 hours so all the petrol was able to run out of whichever cylinder it had collected in, and mostly evaporate from the other manifold branches... otherwise a catastrophic hydrolock might have resulted.

And somehow during the first minute or so of running after replacing the ECU and fixing the earth strap, I realised there was something badly askew, killed it with all haste, and made to do a precautionary oil change. The mixture that came out when I undid the drain bolt was more like diesel than 10w40... :-o

(Car still ran fine, afterwards - despite the rather vulnerable control electronics, VW otherwise made a very rugged engine :D) 87.113.44.131 (talk) 02:12, 1 May 2016 (UTC)[reply]

Digifant, Ottifant

According to German WP, Digifant is a portmanteau of "Digital Injection" and weisser Elefant ("white elephant"). Why? Is there a dependable source? I assume VW engineers are typically Otto Waalkes fans, but I am still uncertain of the origins of this peculiar name. Mr.choppers | ✎ 02:46, 31 October 2024 (UTC)[reply]
