The cruise control has stopped working and the IID Tool shows the module as not fitted. Where could it have gone? It was working fine until I had to replace the stop/start battery.
The stop/start had not worked for ages but as I preferred it off I hadn’t done anything about it until there was a huge flood of faults. They did not show on the IID tool, just one about the battery so I replaced it. Got a big list of faults after that but all cleared and did not return. However, no cruise control (or stop/start either) with IID tool showing the cruise control module as not fitted.
Have gone through a number of vehicle start-ups over a couple of weeks but none have found the cruise control. Anyone got any ideas? Is this one of the faults that needs shorting of the battery leads to clear it?A vaccine does not stop you catching a virus, or passing it on, or getting ill from it, really ill.

Hard reset is what you're describing and it's certainly a good starting point.
Bonnet open and let car go to sleep before doing the shorting. At least 5 minutes to make sure it's asleep..

Don’t touch the leads together without disconnecting them from the battery first!It can when others can't,
It will when others won't,
It goes where others don't.
If it had been a nubie posting, I'd have said that too ! .

Ha ha. Shorting the posts could solve a lot of problems! Just thinking this through and I think I should disconnect the stop/start battery first and do its leads as well while the main one is disconnected.
Also, I have a memory of needing a code to restart the radio but I don't see that in the handbook - or a note of the code anywhere. I wonder how one can get the radio to display its code.A vaccine does not stop you catching a virus, or passing it on, or getting ill from it, really ill.

The cruise module is still showing as not fitted. Battery refit reset done on both batterys, then both disconnected and leads shorted, reconnected and both refit resets done. Really, no change.
Stop start has not returned either - though I suspect the cruise module works that as well. The button in the centre console produces the ECO on/off messages on screen though, and the cruise control buttons get responded to by the IID tool in another function.
Any further ideas?A vaccine does not stop you catching a virus, or passing it on, or getting ill from it, really ill. It does reduce the likelyhood of you dying when really, really ill. Stay Alive - KEEP AWAY FROM PEOPLE.

Shot in the dark check the fuse (behind the pigeon hole) to the power socket(cigar lighter), ISTR I took power from that socket when I retro fitted cc a few years back.
I/we assume you have fitted a new fully charged SS battery, just because it’s new don’t mean it’s fully charged, normally if it is not fully charged the SS light will come on, but if the main battery is down on amps or volts the SS will not work and you will not have a light on.
There is an update available for the instrument pack which you could try with the Iid tool!
Sorry about my last post but duty called and I had to leave in a hurry without finishing It can when others can't,

Thanks for the dark shot. I can't see aything on dash that could be called a pigeon hole - there is an ashtray and two power sockets in the middle but does not look as if it comes away easily. Both batteries were charged with Cetec charger. I'll look for the instrument cluster update tomorrow. Would also look for the physical CC module if I knew where it is just in case it has fallen off socket.A vaccine does not stop you catching a virus, or passing it on, or getting ill from it, really ill.

If you’ve got power at both central sockets it’s not the fuse. Pidgeon hole is an old term relating to the storage compartment situated in the footwell in front of the passengers knees, drop it down and squeeze both outside edges in and it will hinge to the floor, this will reveal the cabin fuses, I don’t remember the number of the fuse in question but there should be a diagram with all fuses on the back of the door.
Take care when removing them as they tend to get lost It can when others can't,
It will when others won't,
It goes where others don't.
Fuse in pigeon hole was checked visually and now confirmed by meter. As is the one in the engine compartment. Still no idea what/where the cruise control module is to check if it has dropped off or melted. IID continues to show module as not fitted. Getting past silly now.A vaccine does not stop you catching a virus, or passing it on, or getting ill from it, really ill. It does reduce the likelyhood of you dying when really, really ill.

I don’t see how changing the SS battery can directly affect the CC.
If the main battery is aged and not providing sufficient amps the SS will not work even if it’s been on charge all night and the engine turns over and starts normally.
The other items notorious for causing illogical faults are brake lights, bulbs and brake light switch, new switch is about £20 followed in your case by the clock spring or the short connection lead from CS to CC switch pack, 30 minutes job to take steering wheel and airbag off to check for continuity.It can when others can't,

Whilst I got a 2011 D4, found this on the ‘ms shared drive’ listed somewhere here.
It’s in italian, but …
If I’m reading it right, assuming you've for the adaptive speed control, the only ‘module’ is the adaptive sensor thing in the front bumper? Is that what’s missing in your IID scan?
Otherwise, its the ECM doing the honours.
Haven’t found an english version of your D4 service manual, but mine does say that the cruise control is disabled if there are any errors in the system.
Assuming the start/stop feature will be controlled by ECM as well, so linked issue?2011 D4 XS : LHD
2005 D3 HSE : reluctant sale, but moved abroad. Great car.
I agree a new SS battery should not affect the cruise control but there was a huge system fail when the old battery finally went. There had been the circle+triangle light in dash for months but as I didn't use the SS it did not bother me. Then the cruise control failed on a journey and on restart there were multiple failures and warnings. Suspension on bump stops and a long menu of systems not working.
Oddly, the IID tool showed only one fault - lots of words about the SS battery. No mention of the other faults at all. Fitted new (fully charged) SS battery and cleared all faults and they did not come back, but cruise control was shown not as a fault but "not fitted". It is the vanilla cruise control so no front sensor - only item 2 in the diagram is probably there. I'll have a look for anything that looks like that but I suspect it is hidden well away.A vaccine does not stop you catching a virus, or passing it on, or getting ill from it, really ill.
