ABS/EDL Dash LIghts Intermittent

2001 EuroVan, 24 Valve, dash warning lights = ABS and EDL intermittent. I can't pin the occurrence to any one thing, although around town mostly. Noticed recently can not down shift to D1,2, etc. unless already in drive and moving. Ideas?

Those need to be checked with a VW or VAG-COM scanner.
