Intermittent ACC and ABS faults

[Kev8277]

2016 Superb automatic diesel. Started with an intermittent ACC fault and now getting intermittent ABS faults at the same time (which then triggers tyre pressure, park pilot, auto hold, start/stop, etc.).

Diagnostic scan not providing an obvious solution but gave ABS faults on multiple wheels which leads me to think it is not a single ABS sensor issue. Battery is also good.

Also, I don't understand why parking sensors would be affected by this. 

Anyone experience similar issue/solution???

Thanks.

Parking sensors are turned on/off based on vehicle speed, so if the ABS sensors have a problem the vehicle speed is not reliable and hence the parking sensors report a fault.

 

Multiple ABS sensors reporting an intermittent problem suggests an intermittent connection at a common point, such as the connector on the ABS module possibly due to corrosion, or (worst case) a failing ABS module. Obviously check the connections first!

That now makes sense about the parking sensors.

Good idea on the ABS module connectors, will do that.

All other past experiences/suggestions welcome.

Thanks.
