Talk:TDI (engine)

message: Use of waste vegetable oil and straight vegetable oil in TDI engines appears to be a topic of some controversy. I suggest editing the section on SVO/WVO to a) mention controversy b) list manufacturer statements c) include any references that can be sourced. This should be purely NPOV. Comments?

thread_title: WVO/SVO in TDIs

message: A small suggestion, but can someone add a "Badging" section or paragraph, explaining what the different colors of the "TDI" badging means? (ie. red I, red DI, red TDI, blue I, etc.) UrPQ31 (talk) 13:47, 2 June 2008 (UTC)
replies: text: There is no consistent overall guidelines for the differing colours of badges.  This specific issue should be addressed on individual Volkswagen Group car or van articles.  Rgds.  78.32.143.113 (talk) 16:41, 26 December 2009 (UTC)
thread_title: Badging

message: I'm removing the following paragraph because the supplied link no longer says what is quoted and Google cannot an equivalent statement anywhere on VW.com.
:Volkswagen of America does not endorse the use of biodiesel in high percentages.  They state that "[s]hould the use of substandard fuels, or higher level blends of biodiesel, damage your engine or fuel system, such damage cannot be covered under warranty".  Thus a high-percentage biodiesel user who encounters fuel system problems can reasonably expect difficulty obtaining service under warranty if the biodiesel use is apparent to the dealer.
Has VW changed their position on biodiesel? --Imroy 10:34, 4 June 2007 (UTC)
replies: text: AFAICT the VW warranty says that they do not warrant damage from a bad batch of fuel, period.  It's not a biodiesel issue, per se.  Presumably refiners are less experienced making ASTM fuel from vegetable oil (and now, animal fat too! per the Tyson-Cargill arrangement) but AFACT that's a lot less of an issue.  I think the comment about VW voiding the warranty is FUD and should be removed under NPOV. --206.79.158.100 (talk) 23:21, 8 January 2008 (UTC)

text: Inside the fuel filler flap of my Skoda, powered by the 100 bhp 1.9l TDi engine, it explicitly states "no biodiesel".  Mr Larrington (talk) 13:53, 22 July 2009 (UTC)

text: VW Australia also specifically state no biodiesel.  In my 2007 Golf TDI it also has the 'no biodiesel' sticker.  peterl (talk) 23:40, 22 July 2009 (UTC)
thread_title: VW biodiesel/warranty reference gone

message: Direct injection turbodiesels are produced by many manufacturers, yet the overwhelming focus of this article is VAG products. I don't think it's appropriate for wikipedia to have an article specifically for a trademarked name when similar technology is produced by other companies. Therefore I propose to move the content across to Direct Injection (or possibly Turbochargers, but DI is better because the breakthrough for TDI was when DI became possible, since non-DI turbodiesels had been around for years by then) 1292simon (talk) 13:58, 11 April 2012 (UTC)
replies: text: Oppose There's some argument for an article on TDI products across all manufacturers, even though VAG's work here was innovative, substantial and notable on its own. However merging this important intersection to either DI or turbocharging would be a very bad move. Most obviously because both of those topics are far broader than this, but also because TDI isn't just about direct injection. Direct injection in diesels has a far longer pedigree than this and the early non-common rail systems have even less in common with it. Andy Dingley (talk) 14:26, 11 April 2012 (UTC)
replies: text: Yes, DI is broader that TDI. I don't see how this is a reason to have a separate article for TDI, it just means TDI would be a section in the DI article. In fact, putting them together would better show the development from non-common DI to common DI to TDI. 1292simon (talk) 15:11, 11 April 2012 (UTC)
replies: text:  Then it might just as well merge oil engine and hot bulb engine too. You'll have an article that is trying to cover a century of development across vehicles from ships to Golfs, all in one short article. Andy Dingley (talk) 15:35, 11 April 2012 (UTC)
replies: text: Are you playing "reductio ad ridiculum"? If your suggestion is earnest, then hot bulb is a totally different technology to TDI, whereas TDI is a development of DI. The turbocharging article happily covers machines from motorbikes to trucks to ships to construction equipment; so there's nothing wrong with covering a large range of applications within a single article. 1292simon (talk) 01:27, 12 April 2012 (UTC)
