Second Hand Ford B-Max DPF

The DPF is engine-specific, so the engine code is the most important thing to match — common diesel units in the B-Max include the 1.5 TDCi and 1.6 TDCi, each of which can have different DPF configurations. Get your engine code from your V5C or the plate under the bonnet and give it to the breaker alongside your registration. Never assume a DPF from a different engine code will fit, even if the car looks identical from the outside.

The Ford B-Max was produced from 2012 to 2017, and while there was no major facelift that split it into distinct generations, emissions legislation moved from Euro 5 to Euro 6 during this period, which can affect DPF specification. A DPF from the wrong emissions era may not fit correctly or could cause an MOT failure even if it physically bolts on. Always confirm with the breaker whether the donor car's registration and engine code match your own emissions standard before buying.

Trim level does not affect DPF fitment — the exhaust and emissions system follows the engine code and model year, not whether the car is a Zetec, Titanium, or any other grade. You may find minor cosmetic differences in surrounding underbody components between trim levels, but the DPF itself is determined by the engine and emissions specification. Focus your search on matching engine code and year rather than trim name.

Ford did share some engine families across models in this period, but DPF fitment across different model lines is strong confirm-with-the-breaker territory — routing, mounting points, and sensor positions can differ even when the engine code matches. Give the breaker both registrations and let them cross-reference the part numbers before committing. Do not assume compatibility based on engine code alone when crossing model lines.

This is exactly the kind of cross-year question where you need to be cautious, because the shift toward Euro 6 compliance in the mid-2010s means a DPF from a 2012–2013 car may not meet the emissions specification of a 2015–2016 car even if the engine code looks the same. The B-Max ran from 2012 to 2017, and diesels registered toward the end of that range are more likely to be Euro 6 than earlier examples. Confirm the emissions standard of both the donor and your own vehicle with the breaker before buying.

Fitting a used DPF is legal in the UK provided the unit is in working condition and meets your car's emissions specification — an MOT tester checks that the DPF is present and functioning, not that it is brand new. The risk with a used unit is buying one from the wrong emissions era or a worn-out filter that fails the particulate check. Have the breaker confirm the donor car's engine code and year match yours, and consider having the unit inspected or cleaned before fitting if its history is unknown.
