Multiple fault codes on their own don't always help and may confuse. You have to learn how to use V.W diagnostics in measuring block mode to see (and understand) what components in the engine system are actually doing.
My washer stops and the panel display says 'control fault'. The engineer (who's trained to know a thing or two) arrives and then checks the pump works, the heaters are o.k, the drain isn't blocked and the water valve is turning on. After restarting the wash program he investigates what should be happening when it stops and faults, then finds the pump hasn't removed any water but panel diagnostics just flagged 'control fault'. After looking at the pump, he finds it's jammed with coins that dropped out of trousers. Logical fault finding on modern Efi cars is just like repairing washing machines!
