VW Eos

The 1.6 FSI BLF has a maintenance-free timing chain that can nonetheless stretch. The hydraulic chain tensioner has no mechanical stop, which can cause chain skip when parking on a slope without the handbrake.

Symptoms: Rattling immediately after cold start, fault code P0341, in the worst case engine damage from chain skip

The high-pressure pump on the BLF is driven mechanically via a roller follower. If the follower is not renewed every 3–4 years it wears through and damages the camshaft. Metal swarf contaminates the entire fuel system.

Symptoms: Rough running, power loss, fault code P1020 (fuel pressure too low), metallic ticking

In the 2.0 FSI EA113 (BLF), a bucket-type cam follower drives the high-pressure pump. This follower wears and can damage the camshaft. If replaced in time the damage is limited; if delayed, camshaft replacement is likely.

Symptoms: Fuel pressure fault message, engine warning light P0087, power loss

The 1.6 FSI BLF shares the high-pressure pump cam follower weakness common to all EA113 FSI engines. Wear destroys the camshaft and pump. Regular inspection every 20,000 km is mandatory.

Symptoms: Pumping noise from the camshaft area, poor cold start, fuel pressure drop, hesitation under load

Since the BLF as a direct-injection engine does not wet the intake valves with fuel, EGR gases and crankcase ventilation deposit as a soot layer on the valves. Noticeable from around 80,000 km.

Symptoms: Hesitation in the lower rev range, power loss below 2,000 rpm, increased fuel consumption, misfires on cold engine

Drain channels in the A-pillars and rain drainage of the five-piece folding roof become blocked. Water enters the interior, boot, and hydraulic block. Regular cleaning of the 4 drain holes is essential.

The steel folding roof hydraulic pump fails at high mileage or after water ingress. The roof can no longer open or close. Dealer replacement costs over 1,600 €; used pumps available from 90 €.

Thermomechanical overload in the ABS/ESP control unit can break the earth connection and disable ABS/ESP. Affects Eos vehicles produced 05/2008–08/2010. Software update as the remedy.

On the 2.0 TDI, the dual mass flywheel wears prematurely, promoted by frequent short-trip and urban use. Clutch replacement is strongly recommended at the same time. Typical repair cost: 1,200–2,000 €.

Foam pads behind the wheel arch liners absorb water and press it continuously against the inner wing edge. Rust forms from the inside — a known design flaw since the Golf V platform.

The drain hose in the roof pillar becomes detached from the coupling piece and directs rainwater into the A-pillar instead of outside. Mainly affects vehicles before the 2010 facelift. Damp interior trim and wet driver-side floor mats are typical symptoms.

The A/C pressure switch fails and shuts off the compressor, so the system no longer provides cooling. Early build years up to mid-2007 with the Zexel compressor are particularly susceptible.

The plastic gears in the sunroof motor wear out and start slipping. The glass sunroof no longer opens or closes fully, or becomes stuck in the middle position.
