W8 4.0 (BDN/BDP) vs EA211 1.0 TSI
Side-by-side reliability comparison
Specifications
Character
W8 4.0 (BDN/BDP)
"Volkswagen's 4.0 W8 (2001-2004), sold only in the Passat W8 4motion: two narrow-angle VR4 banks, 275 PS, three timing chains at the back of the engine. Smooth, but extremely complex. The plastic chain tensioners and guides wear and the camshaft adjusters fail (about EUR 4,000), and the chain drive and even the lambda sensors need the engine out. It is sensitive to overheating, which can scuff the cylinders. Ignition coils fail. Buy only with proof of chain work."
EA211 1.0 TSI
"Three-cylinder turbo with a dry toothed belt (not a chain) in the Polo, Fabia, Ibiza, T-Roc, Golf and Octavia. German and Czech guides call it robust, with 200,000 km not unusual. Watch for a slow coolant leak from the plastic pump/thermostat module, check the 2018-2020 injector recall, and keep the belt on the interval for your engine code."
