Direct injection leaves nothing to wash the intake valves; German used-car guides name coking of the intake tract and injectors on the 170 PS A16XHT. Walnut blasting is the fix. Legacy EUR 400–800 / 60,000–100,000 km figures from the old row were unsourced and are not carried over.
Short Athens trips bring it forward. Ask for a borescope at purchase on any car over 80,000 km.
