Problematic

Reliability, common problems and owner reviews for the Volkswagen Golf VI 1.2 TSI 85hp (CBZA). Check this before you buy used.

Small turbo EA111 with the family's Achilles heel: the timing chain and its oil-pressure tensioner. Early tensioners let the chain go slack at start-up and jump a tooth — bent valves. Punchy and economical, but you must treat the chain as a known liability and check for a revised tensioner.

Same engine, other cars

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

Known Issues

Timing chain / tensioner failurecritical

Oil-pressure tensioner relaxes when the engine is off; on cold start the chain can jump a tooth and the pistons hit the valves. Telltale is a rattle on start-up.

Fix / Workaround: Fit the revised chain + tensioner kit (newer part numbers) proactively; treat gently for the first minute of cold starts.

Repair cost: €600–€1400

Typically appears after: 90,000 km

Plastic water pump / thermostat housingrecurring

Plastic coolant housings leak/fail, risking overheating.

Fix / Workaround: Replace with updated part when leaking.

Repair cost: €150–€400

Year Cutoffs

2014: Before — Original timing chain tensioner — jump/skip risk. After — Revised tensioner/chain (mostly post-Golf VI).

Mileage Thresholds

After 90,000 km: Timing chain stretch / tensioner failure risk rises sharply.

Pre-Purchase Checklist

☐Cold-start rattle check is mandatory
☐Ask if the chain/tensioner was replaced and with which (revised) part
☐Check coolant level / signs of water-pump leak
☐If paired with DSG7 (DQ200), check gearbox health too
