VW Eos

The EA111 CAVD is notorious for premature timing chain stretch. Defective tensioners and worn guide rails can cause chain elongation from as little as 40,000–60,000 km. If the chain skips, immediate engine damage results. VW only solved the problem with the EA211 (timing belt).

Symptoms: Rattling noise on cold start, MIL, rough running, in worst case abrupt shutdown

All CAVD engines up to 2012 have structurally defective pistons. Under thermal load the ring land breaks; piston rings lose their sealing function. Oil consumption of 1 litre/1,000 km and more is typical. Repair with piston replacement costs €1,500–4,000.

Symptoms: Blue smoke from exhaust, rapidly increasing oil loss, oil consumption above 0.5 L/1000 km, power loss

The magnetic clutch that engages and disengages the Roots supercharger fails prematurely. Fault code 04269 (magnetic clutch for mechanical charger). Repair: €450–680 including fitting.

Symptoms: No pull in the lower rev range below 2,500 rpm, normal power above (turbo alone), fault code 04269, rattling from engine bay

The variable camshaft adjuster on the CAVD is sensitive to oil pressure and oil quality. Insufficient pressure from old oil causes malfunction or wear. Solenoid valve or adjuster unit: €150–600.

Symptoms: Fault code P0011/P0021, idle hesitation on cold start, occasional misfires

As a consequence of the piston/oil consumption problem engine oil enters the intake tract and oils up the intercooler. The oil burns in the cylinders and can irreparably damage the intercooler. Intercooler replacement is necessary alongside piston replacement.

Symptoms: Oil film in intake manifold, blue or whitish exhaust smoke, power loss from oil film in charge air system

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.
