Telematic module reusable?

Officially yes
Unofficially no
What makes you think it needs replacing? We can likely fix your existing module but we’ll need the car here at the workshop

Internet constantly drops out even if cell signal is good or using wifi. Multiple DTC’s from the telematics. Infotainment crashes. SOS fault on dash. Unable to connect to app I gotta pull the module to check it properly. But I suspect the module is failing. Tried software updates using ODIS no change.
The fault is more frequent in heavy rain and almost guaranteed after washing the car. I suspect water ingress. Once I pull the module I should be able to check for corrosion. I can send you evidence after I get the module out but I suspect the module is toast. and will require replacement. I’ll know more next week.
Are there any antenna related faults stored?
I'd be exploring the possibility of a faulty antenna module with the symptoms you have.

Try resetting the module... Press the SOS button on the ceiling, hold the button down, and without releasing it, cancel the emergency call on the infotainment screen. When you see the LED on the ceiling light blinking, it's resetting... You can stop pressing the SOS button now. Then you have to turn off the car for at least 30 minutes so that the control unit can go to sleep. Option 2 if this doesn't work. Replace the SOS module battery This module is behind the infotainment screen, so you'll need to remove it. There's a video tutorial on how to remove it.Once you access the communication module, replace the battery. This battery should last a long time since it's only used when the car is off (and to provide power, for example, in case of an accident)... But it could be the cause of those power outages if the battery is faulty.It is not optimal.
This one in particular is from an Ateca, but the Leon MK4 uses the same one. In the case of the Ateca, the module goes behind the digital display. If a battery replacement is necessary, I also recommend leaving the battery out for about 15 minutes to reset the module, and then installing a new battery.
Thank you.
I haven't looked at the car properly yet, I've only pulled fault codes, updated the mib and assumed worst case for some stupid reason.
I'll look into the reset and the battery, update the telematic module and if there are still faults present I'll go down the route of an antenna issue as suggested by james.
Only if none of that works will I go down the route of looking into the telematic module for hardware faults.
I'll let you know when its solved.
