You miss the point - the towbar is a genuine part. The module is a genuine part. The car is the problem - it is a parts bin special with some 2017 electronic modules and some 2018 modules and it’s this that is making it impossible to fit an electrically deployable towbar.

Having had Audis for over 20 years, I know that they don’t do this with their cars and when there’s a new mode year which brings different parts or a new method of software coding (2017 was SDD, 2018 onward is Pathfinder), they have a break in production and then transition to a new production run.
Also, it’s very easy to do your own coding and the software and interfaces are readily available. I have that software and interface and if it were an Audi that was having a towbar fitted, any model from the last 30 years or so, I could code it in myself.
Instead, I’m trying to do the right thing, I bought a genuine towbar for my model year, a genuine module for my model year and fitted them. I had to take the car to the dealer for them to code them in. First attempt had the dealer saying the module was wrong, presumably because the part was talking to another part of the wrong model year. They replaced it (so another day where I had to take the car in to the dealer), then said that the replaced module wouldn’t talk to the towbar armature itself, so they investigated further and found that the car was a mongrel, electrically speaking and there was no possibility of getting the top of the range towbar installed.
It is this, together with the dealer apathy and indifference, together with JLR’s approach of putting out half-ar5ed cars with pathetically slow software, with low res graphics to boot, who insist that their franchisees must sell both J and LR from the same site, meaning that the dealer who I bought the car from shut 6 months after and my local one will be going the same way soon too as they cannot expand, that means I cannot buy another Jag. Love the way it drives, love the way it looks (now that Ian Callum has left, I doubt future models will be as pretty), but the interior ergonomics are terrible (basics like centre arm rest and foot arm rest being different heights for instance), the software is awful, the driver interface is basic and unintuitive and although I had a test drive before I bought, they’re not really things that show up in 30 mins or so.
I’ve tried to buy ‘British’ but the experience has left me cold and unable to stay with JLR in the future. Who knows what the future holds for the company? I can see Tata selling the brand to the highest bidder very soon and the slide will continue.
I hope I’m wrong. I’d love to be driving an I-Pace in a few years time as that is a very good looking and driving car (I took one around Oulton Park a couple of years ago), but the software and ergonomics are the same as the F-Pace, as is the difference diagnostic software, so I can’t see that happening.

I know I am resurrecting an old post but I'm having very similar problems to MiCoHi.

The car is 2018my first registered in Dec 2017. I have bought and fitted the 2018my onwards detachable towbar and 2018my onwards trailer electrics module. The car is due to be coded next week.

But in the interim, I'm getting all the same issues as MiCoHi had. IEB is not available. The ICTP also turns off randomly and then comes on again, indicators not working then working again. In addition sometimes it is not recognising the smart keys.

My little Autel AP200 OBD reader says canbus issues. I don't know if this is because the car isn't coded yet or if there is a fault with the trailer module or if this car s also an amalgamation of 2017my and 2018my and I need an earlier 2017my system, which would involve changing the whole towbar again. If I can I would like to avoid the possibility of the dealer trying to code the car only to find I have the wrong hardware. I've fitted quite a few towbars, the last to a 2014 XF. This had to be coded but didn't upset the car's software in the interim. The same with my previous Freelander 2.

Can anyone shed any further light on this?

Well, I can't shed any further light on this - I gave up and sold the car.

Now happily driving around in my new Tesla Model 3 - more space inside, a little less boot room though, not that I needed it all. Faster, cheaper, better built (seriously, it is!) and more fun to drive than the Jag and the comfort levels are off the scale in comparison. And I have a working tow bar too!!

Never going back to JLR and I suspect in 10 years time, there won't be a company to go back to anyway, the way it's being mis-managed. Shame!

Jaguar will only fit a towbar if they supply the entire kit because spurious parts waste a lot of workshop time, and probably don’t work properly, they won’t code a towbar supplied by others for the same reason.

If you get a towbar fitted by an aftermarket supplier, they might manage to code it more likely not, regardless what they claim, you can fit a universal relay and the lights will work but you won’t get the extra towing features and the rear sensors sound when you reverse. It’s a bit irritating but you don’t reverse that often, the consolation is that you’ve saved about £1000 over a dealer fit towbar.

Have a factory fit towbar is first choice every time, second choice a universal relay fitted by a specialist, removing the bumper and DIY fitting is a real pain in the a**.

Well. I’m hoping I’ve sorted this issue out. In case anyone else fits a genuine towbar.

For anyone in the same situation, the weird car symptoms occur I now know when a 2017my towbar and towing module are fitted to a 2018 - 2021 car. I bought what was presented as correct part numbers for 2018my from an eBay trade seller. I fitted it. I had exactly the same issues as MiCoHi. I disconnected the electrics and car went to Jaguar dealer for other work and to have towbar module switched on. They found that in spite of the boxes I had received showing the right part numbers, the towbar module definitely was 2017my not 2018my. As the electric harness is part of the towbar and the connections are different, to cut a long story short towbar and electrics supplied came off again went back to eBay supplier. Another 2018my towbar and module were sourced from a mainstream supplier. This confirmed my original bits were definitely the wrong parts but in the right boxes. New towbar and module fitted. Car working absolutely fine and trailer board already working. An independent is switching the full goodies on soon. Fingers crossed but fairly confident now.
