  1. Limerick Audi Dealer true to their word... Car back with new upgraded ad blue tank and ECU, pressure quality sensor also including re-new injector pipes into engine bay,injector working well so only thing not replaced. All done for around 950 plus VAT... Happy, very happy! 2 years warranty now on system as replaced. Big thank you to Joe Duffy Audi Limerick, especially Michelle (service manager), who calmed me down and made everything right with the world...
  2. Hi Guys, Audi themselves will not do anything for me as the car is outside 3 year warranty. However Audi main dealer have said they will give me goodwill (amazing!)and pay for parts etc, if I cover ramp time. I had a look for information on C8 model A6 Ad Blue and found a section under SCR = Selective Catalytic Reduction. I have created a pdf file for information on system Audi work shop manual. That I can understand whats involved. I have attached. ADBLUE A6 A7 C8.pdf
  3. I have had a fairly good conversation with main dealer (service manager) where they seem genuinely quite concerned that such a small millage car 2019 model, looking to see if Audi themselves will pick up on the issue. Bottom line the diagnostic scan at 200 euro can tell no more than the scan I did myself. (i.e Ad blue ecu not responding to scan and Adblue quality below recommended urea quality. posted 6th Nov car was taken to main dealer on 7th) It looks like when these problems occur Audi has no idea themselves as to the final issues, hence the reason to continue replacing parts until the problem is solved. Of course with this procedure, I can do same in my own garage without the costs of main dealer ramp. I guess my main concern now is I no longer have faith in the Ad Blue system, and would no longer feel comfortable taking this car on any form of long journey as this issue may re appear, and the fact I have a countdown until the car will not restart! This is purely an emissions problem, and does not affect the reliability of what is a fantastic engine. Of course not being able to start this engine or have a current work around is now my issue. My options are now sell the car for a petrol Audi, or carry around spare parts for the Ad Blue with the knowledge of how to replace them.
  4. Checked with Audi Belfast price of parts. 219.60 Adblue ECU Pressure sensor ( there is no quality sensor? on my car) 130.00 These include VAT. Does anyone have the schematic for the car to see whats involved in replacing parts. Thanks in advance
  5. Well got a call from main Audi dealer in Limerick. Said it was the main AdBlue ecu as I suspected from acds scan. Told me 799.00 euro to replace unit and 180 euro for the acds scan. Its in their, so as they said this would sort it, I said go ahead... Was expecting to get a call to pick up the car, but today they called and said its now the adblue quality sensor.... Could of starting replacing parts at my local garage... to solve... they want another 350 euro, and then what ever happens after that... Very disappointing to be honest, I told them to just give me the car back, no need to replace parts.
  6. Main dealer called to say the car needs a new AdBlue ECU. Not a big deal easy enough to get, as below on ebay etc.. Not sure how easy to fit, but I did ask what went wrong on such a low millage car. They are looking around 86 gbp on Ebay... Im told approx 2 hours to fit? Lets see... what happens next. Recall on A6 C8 version rear suspension anti roll bars, plus 2 software updates.
  7. VCDS cable arrived, did a quick scan. I note the % urea is 20 and should be closer to 35%. Also I have nothing coming back from reductive ecu... Will not clear fault codes as this will disrupt Audi main dealer scan... Good to know what faults exist before and after main dealer visit. Voltage on terminals also slightly out of recomended level indicating possible issue with control mod ecu. Will keep updated in relation to outcome..

  8. 40k miles 60k klm.... Sounds correct Richard. I did not change filters even though I have them, as Audi Limerick advised they do not change them, just ATF fluid. I have ordered a new Rosstech cable to run diagnostics to see what the car has filed as faults since ATF change. I have opened a new question in relation to ADBlue pump. Should not be connected to ATF fluid change.
  9. I had this fault about 6 months ago... but before I had a chance to look into it, the fault cleared itself when parked over night. Always put in branded Ad Blue (Normally Redex) from a new container to avoid the issue with crystallization of the urea. It has just appeared again and may of course clear itself, but thought I would see if anyone else has had the issue. And how it ended up. Been asked to drop car in for software updates... Not sure if this will cure issue from reoccurring. Thanks in advance for any thoughts..
  10. All sorted... Mechanic figured out the amount must be 3.5ltr ATF and a reset to the the hydra pump. All faults automatically cleared and car running well. Car effectively protected itself from any damage, which to be fair was clever. Thank you Gareth... Will need to do a new question...
  11. Hi Gareth, thought that myself... But its Audi that informed me the car is due ATF change at 60,000 klm. C8 Model. Was surprised myself. I did google German Audi sites to check, and its 5 years or 60k klm on most sites. Will get it all sorted today. Best Regards Ian
  12. https://www.auto-doc.ie/vaico/16188200 https://www.auto-doc.ie/vaico/14769996 This is the kit I have to install, for the service. Just to clarify I was not able to get a Mann filter set as they do not have it yet. The second link is oil only plus bungs to replace.
  13. Hi Gareth, Called over to the main Audi dealer and spoke with technician. They recommend just to change the ATF no need at 60klm to change filters etc. I have the kit for change popped the car up on the ramp at my trusted mechanics replaced the ATF only to see... Put in the ATF ran diagnostics on temp of atf while selecting Drive reverse etc... It did take the 3.6 ltrs ok but now the car wont move and has applied hand brake. Doing full diagnostics to see whats going on... Old ATF fluid was a bit dirty and did need changed, as car has done 72k klm.. If we cannot clear issue will drop out plastic cover and replace with full kit and refill. Best Regards Ian
  14. Hi Guys, Dec 2018 Audi A6 C8, due ATF fluid change. (Every 60k Klm) Audi technician says they just change ATF fluid not filters etc, no need to do anything but drain and change ATF. C8 saloon should take 3.6 Ltrs approx but only 2.5 drained out. Anyone on the forum completed this service to auto box. Not sure if I should still put in the what Audi recommend or only what came out? Thanks any ideas would be great..
