A buyer's guide to used BMW 1 Series fuel tank

No two fuel tanks are quite the same across different vehicles, so getting the specifics right matters when you buy used, second hand or a replacement. Answer a few quick questions below and breakers will only quote if they have the exact matching part in stock:

Fitment questions

Will a fuel tank from an earlier BMW 1 Series fit my newer one?

The BMW 1 Series ran across two distinct generations: the E81/E82/E87/E88 from 2004 to 2013, and the F20/F21 from 2011 to 2019 (with a facelift in 2015). These generations are completely different platforms, so a tank from one will not fit the other. If your question spans that 2004–2013 versus 2011–2019 boundary, confirm compatibility with the breaker against your exact registration before ordering.

Does the fuel tank from a 2012 BMW 1 Series fit a 2015 model?

A 2012 1 Series sits in the E87/E88 generation (2004–2013), while a 2015 model is an F20/F21 (2011–2019, facelifted 2015) — these are entirely different platforms with no shared underpinnings. Even though the two model years overlap in the market, the tanks are not interchangeable across that generation boundary. Ask the breaker to match the part to your registration or chassis number to be certain.

Does it matter whether my BMW 1 Series is a petrol or diesel when buying a used fuel tank?

Yes — fuel type is a key fitment factor, and petrol and diesel tanks are not interchangeable even on the same generation of 1 Series. The engine code on your V5 or from a VIN check is the single most reliable detail to give a breaker, as it confirms both fuel type and the specific engine variant. Always supply this code when requesting a quote.

Does the trim level affect which fuel tank I need — for example, does an SE need a different tank to an M Sport?

Trim level does not affect fuel tank fitment on the BMW 1 Series — SE, Sport, M Sport, and M135i all share the same basic tank within a given engine code and generation. What matters is the engine code and fuel type, not the badge on the back. Do bear in mind that ancillary items such as fuel pump mounting brackets or sender unit connections can vary, so confirm those details with the breaker against your registration.

I have a BMW 1 Series with a B47 diesel engine — will any B47 tank fit regardless of year?

The engine code is the most important starting point, and a B47-engined 1 Series is a strong lead for finding the right tank within the F20/F21 generation (2011–2019). However, mounting points and ancillary connections can change during a production run, so the breaker should verify the part against your full registration rather than the engine code alone. Supply your reg or VIN when requesting a quote to avoid any mismatch.

Can I use a manual-gearbox car's fuel tank on my automatic 1 Series?

Gearbox type can influence fuel tank design on some platforms due to differences in transmission tunnel shape and underbody layout, so it is worth flagging to the breaker whether your car is manual or automatic. The safest approach is to give the breaker your registration number or VIN so they can source a tank from a like-for-like donor vehicle. Never assume a straight swap without checking.
