If you don't already have the DICE and VIDA tools then you'd need to acquire them or book into a garage having them. Either way, you're looking at £100 upwards and even then, if it shows comms/signal loss errors to multiple modules the place to start is still going to be cleaning and checking wiring connections.

Since we're talking basic maintenance rather than throwing new parts at it, I don't see the issue with making an informed guess, if you're prepared to spend the time and a few quid on consumables (and still be defeated).

There's still every chance the CEM has failed and is irreparable but cross that bridge when you get there.

I recommend a contact cleaner from a well-known brand and also a small plastic brush to be able to give the contact surfaces a good scrub over. In the case of the vehicle I repaired, I went the whole hog - I removed all the fuses (noting carefully where everything goes come replacement time) and opened up the module, so that I could scrub and clean the tracks and solder joints of the PCBs too (mineral deposits from traces of corrosion can cause problems too, not just the contacts in the plugs).

The location in the vehicle sounds the same as the one I worked on. It can be done but you'll need to contort yourself in the footwell a bit to get good access. A head torch for illumination will make things easier.

AND - take some pictures of where all the plugs go into the module before you starting taking them out. They are all keyed and of different sizes (from what I remember) so they can't go back wrong however, there are quite a few and it can be daunting when faced with them all hanging there ;-)

Good luck.

Yup, photograph everything, every fuse location, every catch, everything. It's amazing how helpful it can be if you're doing something you're not overly familiar with.
