Same here.
Last year my DEM module failed due to water ingress, it caused a lot of noise on the CAN network, causing loads of other faults (ABS, Limp Mode, Transmission faults etc).

Got the unit reconditioned by VolvoDiagnostic for £100, and it was about £36 for oil and filter kit from Volvo.

Took the opportunity to strip and clean out the pump, all good.
