Radio controlled clock module on B8

[Audidua]

Hi all! I need help with this. Radio controlled clock isnt functioning as he should. I've enabled this in MMI but theres no radio antena icon on DIS near clock and nothing happens. I left it on for a few days but nothing. How to check is there somewhere a radio clock module? Where is its location on the car? Is it like on b6 under rear bumper? It's a little bit strange if I have that function on MMI but no signal. Just for information my country (Croatia) is covered good with radio clock signal from Frankfurt in Germany. I had this on my ex car b6 and was working fine.

The clock antenna is fitted behind the rear bumper; on the left hand mount. You have to have the antenna (under bumper), module (on back of instrument cluster) and enabled in 17-Instruments for it to work.

So its about rear bumper? I dismantled instrument cluster but found nothing there, no additional plug-in just the main cable.

Sorry, older Audis had a separate module pinned to the back of the cluster.

The antenna/module is behind the rear bumper cover on the left hand side. It is attached to the support bar - rather than the cover itself. It has a three pin connector and is wired directly to the dash on the 32-pin connector. There is an adaptation value in 17-instruments to say how often it updates; the value being zero if not fitted. I don't know if there is a bit to set in long-coding.

If you want to retrofit, you will need the following:

• 4B0 919 145 B - Receiver for radio-controlled clock
• N 104 128 04 - bolt (x2)
• 8K0 973 703 - plug coupler

You will also need a set of repair wires with the correct pins for the above plug coupler and the dash plug coupler (1J0 972 977 G).

• Pin 1 to dash pin 24
• Pin 2 to ground
• Pin 3 to dash pin 23

Let me know how you get on - as I might have a go myself.

Ok, thats quite usefull information. Can I find out over VCDS if my rear bumper module is malfunctioning just to avoid bumper dismantle? If the VCDS shows an error then I'll go for replacement. Thanks!

Could you not just adjust it manually?

Yes I can set it over MMI in "Time" settings> radio clock but no antena icon on DIS even if I left it running for a month. I bought my car in Frankfurt, Germany where is the base of Atomic Clock signal and set the radio clock on right there. I drove to Croatia and nothing appeard on DIS.

Situation update.: few days ago I went to my friends who has original Audi VAS and he tried to activate antena module by starting a sync but no luck. Antenna icon didnt appear on DIS. He checked is module faulty maybe but all is ok.

Update II
Few days ago I tryed to off /on the remote clock with VCDS but again nothing happened. It is always turned on in MMI but icon didnt appeared. If theres a fault on antenna module should I see it in VCDS module fault reader?

Recently I was looking into this concerning a thread on another forum and radio clock for the Audi A6 4F/C6.

If you view measuring block 2 data window 2 in module 17 :-

test off if no radio clock coded into module 17.

n.OK malfunction in receiver or if radio clock coded in but receiver not fitted.

OK receiver working.

When I coded in radio clock into my A6 4F/C6 when it does not have a receiver for one there were no DTC's in module 17 or autoscan log, only MVB 2 data window 2 in module 17 showed Receiver N.OK.

Have you visually checked you have receiver?
