Technical 2019 Ducato TPMS intermittent

[Foxtango]

Fiat Ducato 2019 2.3 140Hp 9 speed auto
I have an intermittent problem with TPMS that sometimes causes the error indication on the dash.

MultiECUscan shows
Other / TPMS (Tire Pressure Module)
Tire Pressure Control (TPMS) Schrader (2/3 axle)
ISO Code: F4 02 8A 0D 62
Hardware number: 1374401080 - Ver: 05
Software number: 90551098 - Ver: 00D2
Errors found:
C1012-88 - Tire pressure sensor location - Bus OFF
C1014-88 - Tire pressure sensor location not determined (left or right) - Bus OFF

When viewing the errors I notice the EMC level is always high ~130%

Charting the 4 tyre pressures, Battery level and the EMC shows this.

Just seems to be dropping out randomly as if there is some coms issue?
No other modules showing any errors
Any ideas or other things to check

Thanks

Jim

I also encounter this. Electromagnetic interference. Inside the car or outside. Is this not a motorhome?

Dmitry,
Yes the ducato is base unit for a campervan conversion.
Knaus Boxstar.

I will disconnect the leisure batteries and the battery to battery connection between the van and leisure batteries to see if the EMC level changes.

Thanks
