  1. Thanks. I've seen countless YT videos and posts over days on end. Also, the parts catalogue diagrams I've seen are confusing - so many different ones and nothing that clearly identifies them as being relevant to my specific car. Not much on YT about BiTDIs at all in fact. I believe there are lots of differences in the layout compared to the normal TDIs. I've had a peak underneath the car but can't see anything obvious. I'd rather not have to remove any covers unless I know what's hidden by them. Apparently the injector can be just about anywhere, front or back, depending on the exact model. It's not even obvious to me where the Cat' & DPF are. I'm told the injector is somewhere in between them. And yes, "reluctant" injector is possibly appropriate. Or should that be "over-keen" in my own case? 😉 Any more ideas about *where* exactly this is hiding would be very welcome.
  2. Thanks for the photo. That's exactly the same as mine (3.0 BiTDI). Guess yours is also RH drive (in the UK)? However, I'm pretty certain it's neither of those 3 connections into the exhaust. The SCR injector apparently has 4 attachments: 1 for the electrical connector, 1 for the Adblue feed and 2 other pipes (whatever they're for). See the attached pic. I've put about 40 Ltrs of Adblue in over the last couple of months and done no more than say 3,000 miles in that time. Also been using the Wynns de-crystallizer each time in the hopes that might clear things up. The last time I put another 10 Ltrs in last week, the warning light disappeared but was back on again within only about 20 more miles. Either there's a mighty leak somewhere or maybe the injector's stuck open (?). Inside the tailpipes looks clean & dry though. Really don't want to put it with a dealer. Countless posts show they don't really know what the issues are either and will just blow your money replacing expensive parts like a new tank, injector, nox sensor etc and still not sort it out. This whole Adblue issue is an outright disgrace. Audi should solve it and offer a free fix for ALL cars, even out-of-warranty. I'm getting very close to an Adblue delete now. Would rather not go that way though. If I can finally find out *where* the injector is I'll try cleaning it as a last resort.
  3. Yes thanks, I was aware of that. But it's a last resort as I'd rather stay legal. Also, I'm not confident that wouldn't bring on other problems later, like no more DPF regens, failed MOTs (if/when they can eventually test for deletes). Mind you, I'm very close to having the delete. This whole Adblue rubbish is ridiculous. I've read countless posts about where the various problems might be, many by people who've wasted thousands trying to get it fixed. It seems no-one really knows all the answers, just ever more theories (including from the manufacturers & dealers!). If I still can't get the answer to exactly where the injector is on this car I'll just give up and go ahead with the delete. Enough is enough!
  4. Thanks for the advice but the more I've searched (incl. here) the more my head spins! So much conflicting info out there. That's why I posted the question here. I really don't want to go down the route of expensive (and often futile) replacement parts like a new tank, pump, module etc. Would you happen to know where the injector is please? Then I can check that out for a start, along with the metering line etc. Thanks.
  5. Hi from a newbie. Can someone please tell me wherebis the Adblue (/DEF/SCR) injector? Having all sorts of issues with Adblue so wanted to check the injector to see if it's leaking or whatever. I'm getting through about 10 litres of Adblue a week (!) so I'm assuming there's either a major leak somewhere or the injector's stuck open with crystallised Adblue. Can't see any obvious leaks under the car so it's more likely the latter I'd think. Getting engine P20E8 faults, Adblue low level warnings etc. I keep clearing the codes, SCR lock and level with VCDS after topping up. It only makes the errors go away for a few days at most each time. I've been Googling forever and can't find any relevant info about where it is. Most relate to non Euro 6 versions which I guess don't have Adblue systems (?). All I know is that it's apparently somewhere in between the cat and dpf (wherever they are!). Pleeeeease someone clue me in before I go nuts! Can't afford to take it to a dealer and no warranty left. Any help much appreciated. Thanks! If it helps, here's an overhead pic of my engine bay...
