Which cars this covers

Only EA111 petrol TSI engines: the 1.2 TSI (CBZA / CBZB / CBZC) built up to September 2011, and the 1.4 TSI with the codes listed in the notes. Other engines are outside this entry.

Models in scope

Volkswagen Golf, Volkswagen Polo, Volkswagen Jetta, Volkswagen Passat, Volkswagen Scirocco, Volkswagen Touran, Volkswagen Caddy, Volkswagen Tiguan, Volkswagen Beetle, Audi A1, Audi A3, SEAT Ibiza, SEAT Leon, SEAT Altea, SEAT Toledo, Škoda Octavia, Škoda Fabia, Škoda Yeti, Škoda Rapid, Volkswagen Eos, Volkswagen Sharan, SEAT Alhambra, Škoda Roomster, Škoda Superb

Conditions on top of the model

• At least one of these must hold:
  • All of these must hold:
    • Engine: 1.2 TSI EA111 (CBZA / CBZB / CBZC)
    • Production date: up to September 2011
  • Engine: 1.4 TSI EA111 (BMY / BWK / CAVA / CAVD / CAXA / CDGA / CTHA)

Notes on scope

The 1.2 TSI window (before October 2011) comes from one parts maker; AUTO BILD gives no production years. The model list follows AUTO BILD's list of cars fitted with these engines, plus encyclopedia applications for the 1.2 TSI. The 1.4 TSI codes (BMY, BWK, CAVA, CAVD, CAXA, CDGA, CTHA) come from an engine catalogue and are not an official list, and no build window is available for them. Volkswagen goodwill terms changed over time (2012 widening, later withdrawal reported in 2018). No official recall or manufacturer bulletin could be opened: the French RappelConso V2 data holds none for timing chains, and the document 2040174/29 is known only through AUTO BILD. The parts maker attributes a rattle in the first seconds after start to the hydraulic tensioner rather than to chain elongation.

How to check whether a particular car is affected

Elgarde reads the conditions above and gives one of three answers for a car:

• Applies: every condition is confirmed for the car.
• Possible: at least one condition cannot be confirmed yet. The entry stays on the checklist, with a note on what to find out.
• Not applicable: a condition is clearly not met (for example a manual gearbox on a DSG entry). The entry is left off the checklist.

What to look for, and where

• Model: one of the models listed above
  The model name as on the registration document, e.g. Golf, 208, 320d.
• Engine code: 1.2 TSI EA111 (CBZA / CBZB / CBZC)
  On the engine plate or block, or from a dealer VIN query. Displacement (P.1) and power in kW (P.2) on the registration certificate help narrow it down.
• Production month: up to September 2011
  The month the car was built (on the VIN plate or in the registration papers). It only matters when the year alone does not settle it.

When in doubt, treat the car as possible: asking one question too many costs less than missing a defect.

How the fault arises, as reported

AUTO BILD (2018) reports that Volkswagen admitted the chain can stretch and skip, and that a supplier is said to have used stamping tools beyond their wear limit; a 2012 trade-press report, citing AUTO BILD, speaks of a production error. For 1.4 TSI engines a parts maker states that the series manufacturer reported quality problems with components (worn tools left burrs on the chain shells, causing premature chain wear) and that the manufacturer requires the newer camshaft adjusters (OE 03C 109 088 E); the parts maker also advises an engine control unit software update afterwards. For the 1.2 TSI the same maker describes a revised kit from 2011 with a wider chain, new guides, a larger tensioner and improved sprocket teeth. If a stretched chain skips teeth, valve timing is wrong; the sources describe uneven running, a possible warning light and, in the worst case, valves touching pistons with severe engine damage.

Reported symptoms

Early signs

• Brief rattle from the engine after a cold start
• A workshop tester shows chain-elongation values outside the normal range

Later signs

• Uneven running or engine warning light
• Sudden engine damage if the chain skips teeth

What to check when inspecting a car

• Documents and records. Confirm the engine code (1.2 TSI CBZA / CBZB / CBZC, or a 1.4 TSI EA111 code) on the engine or from a dealer VIN query, and the build date; for the 1.2 TSI check whether it was built before October 2011.
• Documents and records. Ask for invoices of any timing chain work and whether the revised parts were fitted (on the 1.4 TSI the newer camshaft adjusters and the software update), and whether goodwill was paid.Red flag: No record of chain work on a 1.2 TSI built before October 2011.
• Listen. Start the engine cold and listen to the first seconds. A parts maker attributes a rattle in the first five seconds after start to the hydraulic tensioner, heard more often on older, high-mileage engines, and not to chain elongation; AUTO BILD lists a brief rattle after a cold start as a warning sign.Red flag: Rattle longer than a few seconds, returning when warm, or with uneven running.
• Diagnostic read-out. Ask a workshop to read the chain-elongation values and the fault memory (AUTO BILD says testers show at least four such values, which Volkswagen reads only on complaint).Red flag: Chain-elongation values outside the normal range, or timing faults stored.

Repair and cost

Usual remedy

Replacement of the timing chain kit (chain, guides, tensioner, sprockets) with revised parts; on the 1.4 TSI a parts maker reports that the manufacturer requires the newer camshaft adjusters (OE 03C 109 088 E) and advises a control unit software update afterwards.

Reported cost

EUR 1,600–1,600 (as of 2018-06)
Basis: One reported case in Germany: a second chain job on a Jetta 1.4 TSI at 78,000 km quoted at about 1,600 EUR (AUTO BILD, 2018); the same car's first chain job plus a camshaft adjuster had cost about 4,000 EUR in total. Not a range. Sources: [1]

What the manufacturer and regulators have said

Manufacturer programme

No recall was identified. In April 2012 Volkswagen widened its goodwill on timing chains to 50 to 100% of parts and labour depending on mileage and history (kfz-betrieb, citing AUTO BILD). AUTO BILD reports that a 2012 promise of at least 50% for cars over six years old, for all EA111 TSI engines without a mileage limit, was later withdrawn, a Volkswagen spokesperson saying it applied only to cars already out of warranty at the time.
