The Volkswagen CAAE is a 1,390 cc, inline‑four turbocharged petrol engine produced between 2008 and 2015. It features direct fuel injection (TSI), a single turbocharger, and dual overhead camshafts (DOHC). This engine was part of VW's strategy to downsize while maintaining performance, delivering outputs from 90 kW (122 PS) to 125 kW (170 PS) and torque figures between 200 — 240 Nm.
Fitted to models such as the Mk5 and Mk6 Golf, Jetta, and Scirocco, the CAAE was engineered f…

The Volkswagen CAAE is a 1,390 cc inline‑four turbocharged petrol engineered for compact hatchbacks and sedans (2008-2015). It combines gasoline direct injection (TSI) with a single turbocharger to deliver responsive power and good fuel economy. Designed to meet Euro 5 standards, it balances performance with efficiency for everyday driving.

The Volkswagen CAAE was used across Volkswagen's A5 platform with transverse mounting. This engine received platform-specific adaptations-different intake manifolds and ECU mappings for the Golf, Jetta, and Scirocco-creating minor software interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from Volkswagen technical bulletins (2010-2016) and owner-reported data aggregated from manufacturer service networks (2015-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The CAAE is generally robust, offering good performance and efficiency. Its main long-term concern is potential oil consumption, especially in pre-2012 models. With diligent oil level checks, timely changes using correct spec oil, and addressing any consumption early, the engine can be very reliable for high mileage.
The most common issues are excessive oil consumption (linked to piston rings), failure of the high-pressure fuel pump, and worn ignition coils or spark plugs. Coolant leaks from the water pump or thermostat housing are also relatively frequent. These are well-documented in VW service information.
The CAAE 1.4 TSI was used in the Golf Mk5 and Mk6, Jetta (A5), and Scirocco from 2008-2015. It was also fitted to SEAT Leon Mk2 and Škoda Octavia Mk2 during overlapping production years, as part of the VW Group's platform sharing strategy.
Aftermarket ECU tuning is common on the CAAE platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Fuel economy is good for its performance. Expect around 6.5-7.5 L/100km (38-43 mpg UK) combined in a Golf Mk6. Real-world figures vary with driving style, but it offers a good balance of power and efficiency compared to larger naturally aspirated engines.
Yes. The CAAE is an interference engine. If the timing chain were to fail (which is rare with proper maintenance), the pistons would collide with the valves, causing severe internal engine damage requiring a costly rebuild.
Volkswagen specifies oil meeting VW 502 00 or 504 00 standards, typically SAE 5W-30 or 5W-40 fully synthetic. Using the correct specification is crucial for protecting the turbocharger and minimizing oil consumption. Change intervals should not exceed 15,000 km or 1 year.
