Reliability, common problems and owner reviews for the Volkswagen Passat B6 1.8 TSI 160hp (BZB). Check this before you buy used.

The best all-round petrol for the Passat B6 — torquey and willing. But the EA888 1.8 TSI is notorious for heavy oil consumption (thin piston rings) and timing-chain stretch. A low-oil-use, chain-checked example is good; an unchecked one is a gamble.

Same engine, other cars

This is the same physical engine (CDAA) sold under different names across brands. Reliability is broadly shared — cross-check these:

Known Issues

Excessive oil consumption (piston rings)critical

Thin oil-control rings cause heavy oil burning, up to ~2L/1,000km in bad cases.

Fix / Workaround: Check consumption; revised pistons/rings fix it (major job). Keep oil topped.

Repair cost: €1500–€3000

Typically appears after: 100,000 km

Timing chain stretch / tensionercritical

Chain stretches ~100,000 km; early tensioner can let it jump.

Fix / Workaround: Fit revised tensioner/chain.

Repair cost: €600–€1500

Typically appears after: 100,000 km

Cam follower wear (HPFP)recurring

Follower under HP fuel pump wears.

Fix / Workaround: Inspect/replace periodically.

Repair cost: €30–€120

Typically appears after: 80,000 km

Mileage Thresholds

After 100,000 km: Oil consumption + chain peak.

Pre-Purchase Checklist

  • ☐Ask oil consumption + check dipstick
  • ☐Cold-start rattle check
  • ☐Cam follower history
  • ☐Walk away from heavy oil-burners
