1.2 TSI CBZB

The small turbo petrol that made these superminis genuinely quick. Early examples wore their timing chain tensioner, which is why a start-up rattle matters more here than anywhere else in the range.

Overview

The 1.2 TSI is the CBZB petrol version of the Škoda Fabia hatchback (5J), sold 2010–2014 with 105 PS and manual or automatic. High risk at level 4. The same early chain tensioner failure as its Volkswagen twin, and it ends engines. 4 failure modes are recorded against its engine, gearbox, chassis and shared components, one of which is a walk-away item without documented proof. Prices on this page are illustrative placeholders rather than a sourced market sample. See the methodology for how the bands are derived.

Timing chain tensioner failure (1.2 TSI)CBZB 1.2 TSI€650–€1,400

A rattle in the first seconds after a cold start, then a misfire or a no-start once the chain has jumped a tooth. The original tensioner can release its tension when the engine is stopped, which lets the chain go slack. On restart the chain can skip, and on this engine that bends valves. Volkswagen supplied an updated tensioner, so which part is fitted decides the risk.

Check: Start from stone cold and listen through the first five seconds, then ask whether the updated tensioner has been fitted and get it in writing. Treat an early car with no paperwork as carrying an engine bill.

Later parts: Updated chain tensioner fitted from later production and available as a retrofit

EnginecommonDetectable at viewingwalk away without proofevidence: manufacturer60–140k km

Dry-clutch DSG mechatronic failureVW group DQ200 seven-speed dry-clutch DSG€1,200–€2,800

Juddering at low speed, harsh or refused engagement, warning lights, or a car that won't select a gear. The seven-speed dry-clutch unit's mechatronic and clutch packs wear, and the clutches are far less tolerant of stop-start use than the wet-clutch six-speed.

Check: Drive from cold in traffic. Judder pulling away, hesitation between first and second, or a jolt on the overrun are all this. Ask for the service history. These need fluid and clutch adaptation work.

TransmissioncommonDetectable at viewingevidence: documented80–180k km

Carbon buildup on intake valvesdirect injection€400–€700

Rough cold idle, slow throttle response, misfires, gradual loss of low-end response. Direct injection puts no fuel over the intake valves, so crankcase vapour deposits bake on undisturbed.

Check: Not visible without a borescope. Treat it as a service item that's due unless there's a receipt. It's not a fault, it's an unbudgeted maintenance cost.

Turbo & intakeuniversalNot detectable at viewingevidence: documented80–120k km

Water ingress into the footwellsFabia platform€120–€900

Damp carpets on one or both sides, misted windows that won't clear, and electrical faults that come and go with the weather. The plenum drains under the windscreen scuttle block with leaves and debris, and the water then finds its way past the bulkhead seals. Once it reaches the wiring and control units under the carpet the faults look far more serious than the cause.

Check: Lift the carpets in both footwells and press down hard with your hand, then smell the cabin. Damp underlay on a dry day tells you the drains have been blocked for a while.

Mileage and servicing

What the odometer does and doesn't tell you here, plus the service items whose neglect causes the expensive failures above.

As on the Polo, the tensioner fitted matters more than the distance covered. Look for receipts or a later build rather than a low number.

🇺🇸 United StatesNot sold1.2 TSI CBZB was never a US-market car

What that meansNo US band exists to compare. Any car you find there's a private import, parts and specialist knowledge are thinner, and the price says more about import cost than about the market.

US figures are the EU band converted at a stated rate. No US market differential is modelled: we hold no sourced US asking prices, and inventing one would be worse than saying so. What the comparison does show for real is availability. Most of this range was never sold in the US.

Buyer notes

Our judgement, kept separate from the records it's built on.

Our read, not a record

A Fabia gives you more space than a Polo for less money and shares everything mechanical with it, which includes the chain problem. Start it from stone cold, listen for a rattle, and ask whether the updated tensioner has been fitted. Treat a cheap early car with no history as carrying an engine bill. So check the underside and the rear beam on high-mileage examples, because these were bought as cheap transport and often maintained that way.

Everything above this line comes from the issue and specification records. This paragraph is our judgement on top of them. See how we reach it.
