Used Volkswagen Caddy Fuel Tank

Both years fall within the Mk3 Caddy generation (2004–2015), so a tank from 2010 is likely to be a strong candidate for a 2007 car, provided the engine code and fuel type match exactly. However, there were running production changes across this generation, so confirm with the breaker against your specific registration before buying, as mounting points or sender unit fittings can vary mid-run. Never assume fitment without that check.

The Mk3 Caddy (2004–2015) received a facelift in 2010, and while the body updates were largely cosmetic, some ancillary and mounting details on mechanical components can differ across that boundary. Name the facelift year to the breaker and give them both registrations so they can cross-reference, as we cannot state as fact whether the tank crosses that 2010 line without a part-number check. Engine code and fuel type remain the primary fitment criteria regardless.

No, the trim level — whether your Caddy is a basic panel van, C20, or Maxi — does not affect fuel tank fitment; the tank is determined by engine code, fuel type (petrol or diesel), and year within the generation, not by the badge or spec level. You should supply the breaker with your engine code (found on your V5 or a VIN check) and registration to get the right match. Cosmetic or interior differences between trim grades are irrelevant here.

No — diesel and petrol fuel tanks are not interchangeable, and fitting a tank designed for the wrong fuel type is unsafe and should never be attempted. Always confirm the fuel type of the donor vehicle matches yours exactly, and cross-reference by engine code as well, since engine code is the single most reliable detail for ensuring a used tank is compatible. Supply your engine code to the breaker rather than relying on year alone.

The Mk3 Caddy ran from 2004 to 2015, and the Mk4 Caddy launched in 2015, representing a new platform generation, so a tank from a Mk3 is very unlikely to be compatible with a Mk4 without a specific part-number match. These are distinct generations with different engineering, and you should treat them as separate vehicles when sourcing parts. Always confirm with the breaker against both registrations before purchasing.

A matching engine code is the strongest indicator of compatibility, and it's the most useful detail you can give a breaker when sourcing a used fuel tank. That said, ancillary details such as sender unit connectors or mounting brackets can change during a production run even when the engine code stays the same, so you should still confirm with the breaker against your exact registration. Engine code narrows the field significantly, but only a part-number check closes it.
