Build my inspection planFrequently asked questions
Does the Formentor share Golf parts?
Yes, it is built on the MQB platform, so servicing is familiar and parts are widely available.
Is the DSG a risk?
It is fine with regular fluid changes; hesitation from cold is the first warning.
Which engine should dealers stock?
The 1.5 TSI is the volume seller; the VZ models are enthusiast stock with higher wear.
Any software recalls?
Check the DVSA recall service by registration before you list it.
What are the servicing requirements for the 4Drive AWD system?
The Haldex-style multi-plate clutch on 4Drive models requires an oil change every 30,000 miles or three years. When preparing a car for sale, ensure the pump strainer is cleaned during this service. Standard VAG schedules often omit the strainer, which can lead to pump failure and loss of all-wheel drive.
How long is the high-voltage battery warranty on e-Hybrid variants?
Cupra provides an eight-year or 100,000-mile warranty on the high-voltage battery, guaranteeing it retains at least 70 percent of its original capacity. When appraising a used e-Hybrid, check the indicated electric range on a full charge; expect around 25 to 30 miles in real-world UK conditions, depending on ambient temperature.
