History-Dependent

Reliability, common problems and owner reviews for the Volkswagen Passat B7 1.8 TSI 160hp (BZB / CDAA, EA888). Check this before you buy used.

The 1.8 TSI (BZB/CDAA, EA888 Gen2) is a strong, well-matched petrol for the Superb — but it's the EA888 Gen2, notorious for oil consumption from the original piston-ring design, plus timing-chain tensioner attention and PCV/carbon. A car with the revised pistons (or controlled, documented consumption) and a healthy chain is a good engine; check oil-use history carefully — this is the engine's defining issue.

Same engine, other cars

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

Known Issues

Excessive oil consumption (piston rings)critical

Thin piston/oil-control rings (especially Gen2 CDAA) cause heavy oil burning, rising with mileage — up to ~2 L/1,000 km by ~100,000 km in bad cases. Runs low on oil = engine damage.

Fix / Workaround: Fix is replacing pistons/rings with revised (Gen1-style) parts — major job. Before buying, ask consumption and check the level. Keep oil topped meticulously.

Repair cost: €1500–€3000

Typically appears after: 100,000 km

Timing chain stretch / tensionercritical

EA888 chain stretches after ~100,000 km; early tensioner can let it jump → serious damage. Rattle on cold start is the warning.

Fix / Workaround: Fit revised tensioner/chain proactively.

Repair cost: €600–€1500

Typically appears after: 100,000 km

Cam follower wear (HPFP)recurring

Coated follower under the high-pressure fuel pump wears; if ignored it can damage the pump/cam.

Fix / Workaround: Inspect/replace cam follower periodically (cheap part).

Repair cost: €30–€120

Typically appears after: 80,000 km

Water pump / thermostat leaksminor

Plastic coolant housing leaks with age.

Fix / Workaround: Replace with updated part.

Repair cost: €150–€400

Oil consumption (EA888 Gen2 rings)critical

Original piston rings cause heavy oil consumption; can foul cats/plugs.

Fix / Workaround: Check consumption; revised piston/ring kit is the proper fix.

Repair cost: €150–€2500

Typically appears after: 100,000 km

Timing-chain tensionercritical

Gen2 chain tensioner can fail → chain jump.

Fix / Workaround: Confirm revised tensioner; replace at rattle.

Repair cost: €500–€1800

Typically appears after: 120,000 km

PCV / intake carbonrecurring

PCV faults; DI intake carbon over time.

Fix / Workaround: Replace PCV; walnut-blast intake.

Repair cost: €150–€500

Timing-chain tensioner / PCVcritical

Gen2 chain tensioner can fail; PCV faults; DI carbon.

Fix / Workaround: Revised tensioner; replace PCV; decarbon.

Repair cost: €200–€1800

Typically appears after: 120,000 km

Year Cutoffs

2012: Before — Gen2 (CDAA) — worst oil consumption + early chain tensioner. After — Later revisions improved both (mostly later platforms).

Mileage Thresholds

After 100,000 km: Oil consumption and chain stretch both peak here.

After 120,000 km: Oil-use + chain window.

Pre-Purchase Checklist

☐Ask oil consumption directly and check the dipstick
☐Cold-start rattle check (timing chain)
☐Ask about cam follower inspection
☐Walk away from a heavy oil-burner unless priced for a rebuild
☐Check DSG fluid-change history if DSG
☐Ask oil consumption + check dipstick
☐Cold-start rattle check
☐Cam follower history
☐Walk away from heavy oil-burners
☐Oil-consumption history is the key check
☐Chain rattle / revised tensioner
☐PCV + carbon
☐4x4 availability a plus
☐Rare vs diesels on BG market
