VW Eos

The CFFB (103 kW) as an EA189 variant is mandatorily subject to recall. Mandatory software update increases EGR activation, leading to increased EGR loading in heavier vehicles and short-trip use.

Symptoms: Increased NOx emissions, after update: EGR fault codes, black smoke, increased fuel consumption

The CFFB (EA189) shows known problems with the EGR cooler which can direct coolant into the intake tract. Fault code P2425 (EGR cooling valve). This can lead to engine damage.

Symptoms: Sporadic white smoke, coolant loss without visible escape, fault code P2425, rough running

Specifically for the CFFB with 140hp individual cases of defective clutch pressure plates have been documented. Workshop costs for clutch replacement on the Q3 are approx. €2,000.

Symptoms: Clutch slip, juddering on pull-away, grinding noise, clutch engages unevenly or late

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.

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 optional DSG gearbox is prone to clutch wear and juddering on take-off with frequent city driving. Regular oil changes every 40,000–60,000 km are absolutely essential.

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.
