VW Passat Estate B8 Faults

[gazvwpassat22]

Hi all,

I am new to this forum so wanted to say Hi. 

Apologies if this issue has been discussed previously, I couldn't find it when searching.

I recently purchased a 2017 diesel Passat Estate which has now showing faults nearly every time I start the car/ going slow in traffic / occassionally on the motorway (scary). The car will not start if these faults come up but If I turn the car off and turn it back on, it often works fine.

The faults showing are:

Error: Stop / Start
Error: Stabilisation Control (ESC)
Auto Hold is unavailable
Front Assist unavailable
Proactive passenger protection unavailable
Error: Tyre pressure Loss Indicator
Fault: electronic parking brake

I have taken it to a couple of garages and have had the battery replaced and the O/S drivers side abs sensor changed but these faults keep returning.

I have run a diagnostics using Carista EVO 9.0 and have 53 faults, summarised below:

C114602 - Tire Pressure Monitoring System (TPMS): Signal malfunction
U112100 - Databus missing message / databus implausable message
U01000 - Lost Communication with ECM/PCM
U112300 - Databus error value received
U041600 - Invalid Data Received from vehicle dynamics control module

These messages appear to be sent from different Canbus modules (from what I can gather):

ABS
Power Steering
Air Bags
Instrument Cluster
Infotainment System
Central Electronics
Drivers Door
Front Passengers Door
Ignition authorisation
Trailer
Adaptive Cruise Control
Steering Column Lock
Engine
Heater & air conditioning
Parking/steering assist

Worth noting the car has had a stage 1 remap but the faults were showing before this was done so do not believe this would make a difference.

Its causing me a real headache at the moment and really keen to get it fixed.

Its due to be taken to the garage again on 14th April and I have also contacted a VW main dealer but keen to minimise costs if I can. I was hoping to see if anyone else has seen anything like this and has any advice on what was done to rectify the issue?

Thanks in advance.
