VW Phaeton
A refined development of the VR6 concept with direct injection. Considerably more reliable than earlier VR6 generations. Check timing chains from around 80,000–100,000 km (MWB 208/209). With correct maintenance 300,000+ km is easily achievable.
Facelift Phaeton shines
The 3.6 V6 FSI with 280 hp in the facelift Phaeton combines further improved quality with excellent ride comfort. A discreet luxury car of the highest order.
Engine Weaknesses 5
The 3.6 V6 FSI CMVA suffers from premature timing chain elongation, particularly with longlife oil use. Oil sludge prevents adequate lubrication of the chain tensioners.
Symptoms: Chain rattle on cold start, MIL, fault code for camshaft position
The timing chains of the 3.6 FSI can stretch measurably from approximately 80,000–85,000 km. Diagnosis via measurement blocks MWB 208 and 209 — deviations above 0.5 degrees indicate replacement is needed.
Symptoms: Rattling on cold start, fault code P0016 camshaft position, rough engine running
The high-pressure pump of the FSI system can build excessive fuel pressure (above the 120 bar target). Cleaning and resetting the pressure regulator frequently resolves the issue.
Symptoms: Whistling from the engine bay, elevated fuel pressure values in fault memory
In early production years there were problems with individual ignition coils, particularly at cylinders 1 and 3. Misfires with fault codes. Replacement as a complete set is recommended.
Symptoms: Engine stumbling, misfire fault code P0300–P0306, shaking at idle
At high mileages the crankshaft seal tends to leak, leading to oil drops under the vehicle. A typical wear phenomenon from approximately 150,000 km.
Symptoms: Oil drops under the vehicle, oil smell after driving, slight increase in oil consumption
