    Resolved 5f Module faulty? (2014 A8)

    Sorry it has taken so long to complete this story but I did something stupid. While waiting for the shark fin to arrive, I thought I would try swapping the hard drives between the 5f units thinking that it would either work and save the hassle of loading all my music etc and have reasonably up...

    Resolved 5f Module faulty? (2014 A8)

    I think I am getting somewhere at last. I tried the cheapo GPS antenna form Ebay but this made no difference. What has been puzzling me from the start is that the Sat Nav works as it should and shows that it has fixed satellites etc. Anything I found on the internet referring to a faulty aerial...

    Resolved 5f Module faulty? (2014 A8)

    I got the new 5F module coded and programmed by an independent VW Audi specialist yesterday. Unfortunately, when driving, the same issue of ACC unavailable is still happening. It is not all bad news though, the errors I now have are only for the GPS and telephone antennas and they will clear but...

    Can't get the car booked in until mid January. I will keep you all updated once the garage has hooked it up to the mothership. Bazza

    As you suspected, no option for android auto on this car. As you say, keep it simple and use a phone. I like the car so much that I want to keep it as long as I can.

    Thanks Uwe This is getting me worried where it will all stop. With the "new" module fitted, I was still getting intermittent ACC and braking guard warnings. Hopefully a function of not being programmed correctly but may be something else causing the issue. I have refitted the original unit as I...

    I received a replacement 5f module which as far as I could tell was new old stock and never been used. I installed it in the car, cleared fault codes and took this scan. Monday,16,December,2024,17:40:08:26473 VCDS -- Windows Based VAG/VAS Emulator Running on Windows 11 x64 VCDS Version...

    Resolved 5f Module faulty? (2014 A8)

    Out of curiosity, I cleared all the codes and ran another scan. No surprises considering what has been disconnected including the switches and vents when removing the trim. What I had not expected was that when I took the car for a short drive, the ACC worked as it should so it does not depend...

    Thought I would delve in and see if I could get the MMI module out to have a look. No signs of water damage but looks like I am not the first person to have looked at it. Will see if I can tidy up this connection before the replacement unit arrives. Bazza

    Thanks for the quick response Dr Sheldon. I totally agree that this is a great forum and resource and I am willing to some leg work myself but there is no harm in trying to gather as much info from others who may have similar experience before I make a start. I will of course keep you all...

    Resolved 5f Module faulty? (2014 A8)

    Sorry Uwe, Please accept my sincere apologies for getting your name wrong. If the new module will need component protection removing and a visit to a garage with ODIS anyway, I might as well choose a used one on price. Apart from the obvious radio, sat nav, phone, cruise control and lane...

    Resolved 5f Module faulty? (2014 A8)

    Thanks Ewe Think I will bite the bullet and get one. I had to replace one of the radars with a used one earlier this year (came from Japan). Had to pay £100 for a scan before they would remove the component protection which cost another £100 plus a charge for connection to the server despite me...

    Resolved 5f Module faulty? (2014 A8)

    Thanks for the reply Uwe. I forgot to highlight that it also shows a voltage of 11.50 V. I haven't seen this before. Would it be naïve to hope that fitting a used unit, getting an independent garage to remove the component protection and use the coding from the original unit would cure the...

    Audi A8 d4 3.0 TDI limp mode

    Just to give you all an update. I don't have the facilities to carry out any work under the car at the moment so I ended up taking the car to a local independent garage. Got the car back now and all seems to be working as it should. One thing having to pay out for a NOX sensor but I must admit I...

    Thanks for the reply Dr Sheldon. Not particularly short journeys although I have not been using the car so much lately due to use of a small Corsavan for work. Over the weekend I drove to Aberdeen and back on two occasions (approx. 50 miles each way) I have been getting the occasional MIL light...

    I hope someone can give some guidance. For a week or so, I have occasionally got an engine light on the dash and when checked, it is NOX sensor 2 heating circuit. The car runs as normal and when I reset the error, it will stay off for a couple of days. Today I thought I would try to run a...

    Audi A8 D4 Facelift 2014 ACC module

    I have since replaced the connector on the right side which had signs of water and have checked the resistance between the units and all as it should be, however the faults remain the same and will not clear. The conclusion has to be that one of the units is indeed faulty but which one? These...
