VW Golf
Common-rail 2.0 TDI with 140 hp (EA189). Emissions scandal engine. Fundamentally solid with the update. Injectors more durable than PD variant.
Diesel cabriolet CR
140 hp TDI in a cabriolet: enough power for relaxed open-top motoring. Unusual but it works.
Engine Weaknesses 7
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
The CFFB belongs to the EA189 engine family affected by the VW diesel scandal. Mandatory software update (recalls 23R7, 23Q7, 23R6, 23S1). After update increased risk of EGR valve problems.
After the diesel scandal update the EGR valve on the EA189 (CFFB) more frequently soots up and sticks. Symptoms are black smoke and hesitation; cleaning or replacement necessary.
Symptoms: Black exhaust smoke, hesitation in part-load range, increased fuel consumption, rarely MIL
With predominantly short-trip use the DPF cannot fully regenerate and becomes blocked. Replacement costs approx. €2,000. Regular motorway runs are essential for longevity.
Symptoms: DPF warning display, power reduction, frequent regeneration attempts, in extreme cases engine limp mode
The EA189 engine frequently develops defects in the turbocharger actuator (fault codes P2563/P2564). MIL illuminates and power is limited.
Symptoms: MIL, power reduction (limp mode), fault codes P2563 or P2564, rarely audible turbo noise
Vehicle Weaknesses 17
The hydraulic pump (8P7871791A) loses power after 80,000–100,000 km. The hood opens/closes extremely slowly or stops mid-travel. Hydraulic fluid can leak out.
In the Golf VI rust forms preferentially at the wheel arch edges and on the tailgate — especially if body damage has been repaired unprofessionally. VW economised on the factory corrosion protection for engine, chassis and gearbox.
The Golf VI uses a continuously running compressor without a magnetic clutch (externally regulated). If it fails, metal particles spread throughout the refrigerant circuit. Without a complete system flush the replacement compressor will quickly be destroyed.
The rear brake calipers of the Golf VI seize through corrosion — especially on cars that rarely brake hard. The integrated handbrake mechanisms jam after standing still. GTI models with larger calipers are particularly affected.
In the Golf VI the ignition lock can jam or the electronic steering lock can activate unintentionally, preventing the car from starting. The problem occurs mainly on early production cars.
The electric power steering of the Golf VI can fail due to ECU failures or motor faults. The steering suddenly becomes heavy, which can be dangerous at motorway speeds. A warning light appears on the dashboard.
The hood fabric chafes at the fold lines when driving with the roof open. After 3–5 years rough, abraded patches appear in the fabric that are visually distracting and can eventually become leaky.
The glass rear window detaches from the hood fabric after approx. 8–10 years. The adhesive is degraded by UV and moisture. The rear window heater also stops working.
The Hall sensor for detecting the hood end position fails. An error message appears, windows stay in an intermediate position, beep from instrument cluster.
Water collects in the boot, preferably behind the left trim panel. The cause is leaking tail light seals and blocked water drains that are more heavily stressed on the cabriolet.
In the Golf VI shock absorbers and springs are frequently rated as defective at MOT from the ninth year of operation. Leaking dampers are a typical finding. Pairwise replacement per axle is mandatory.
The soft-touch surfaces in the Golf VI (door panels, gear knob surround, DSG lever, climate controls) become sticky and peel off. The problem affects almost every example aged eight to ten years.
Electric window regulators in the Golf VI fail due to defective motors or wire breaks in the door rubber. The problem affects all four doors, most frequently the driver's door through heavier use.
In the Golf VI the steering rack develops metallic clicking from as early as 30,000 km. Cause: gear backlash from material ingress or moisture. Warranty case on new vehicles.
Microswitches in the hood latches become dirty and send false signals. Hood refuses to open/close; window auto-drop function does not work.
The frameless side windows must drop automatically when the door opens. This comfort feature fails; the glass jams at the top and prevents the door closing.
Due to the reduced torsional rigidity of the cabriolet body, creaking and cracking occurs with the roof closed over road imperfections. Noises come from the roof area and side window seals.
