Second Hand Hyundai i40 Brake Servo

Yes, the Hyundai i40 is fitted with a vacuum brake servo as standard across its production run from 2011 to 2015, on both the saloon and estate (Tourer) body styles. All engine variants — including the 1.6 petrol, 1.7 CRDi diesel, and 2.0 petrol — use a conventional vacuum-assisted braking system, so the servo is a genuine part on this model. If you have been told your i40 has no servo, it is worth double-checking with a breaker or Hyundai dealer against your exact registration.

The Hyundai i40 was produced as a single generation covering 2011 to 2015, with a facelift arriving around 2014 that brought styling and equipment updates but did not fundamentally change the braking system layout. A servo from a 2012 car may well interchange with a 2014 car of the same engine size, but because the facelift year sits right on the boundary you are crossing, you should confirm with the breaker that the part number matches your registration before buying. Engine size is the more important variable here — match 1.7 CRDi to 1.7 CRDi, for example, rather than mixing petrol and diesel donors.

Trim level does not affect brake servo fitment on the i40 — the servo is part of the running gear, not the cosmetic or equipment specification, so a servo from a Classic is not inherently different to one from a Premium. The key variables to match are engine size and whether the car is pre- or post-facelift, not the trim badge. You may find minor cosmetic differences on parts surrounding the servo in the engine bay, but the servo unit itself is unaffected by trim.

The i40 was sold in the UK in both saloon and Tourer (estate) body styles, and because the braking system is fundamentally the same platform across both, the servo is very likely to be shared between them on equivalent engine variants. That said, weight differences between body styles can sometimes influence brake component specifications, so it is worth asking the breaker to cross-reference the part number against your specific registration rather than assuming a straight swap. Matching engine size remains the primary fitment check regardless of body style.

This is not recommended as a straightforward swap — larger or differently-tuned engines can use differently-rated brake servos, and the 1.7 CRDi diesel and the petrol variants (1.6 and 2.0) may not share the same servo specification. Always match the donor car's engine size and fuel type to your own vehicle when sourcing a used servo. A good breaker will be able to confirm compatibility by checking part numbers against both registrations.

Give the breaker your full registration number so they can identify your exact engine variant and model year, and ask them to confirm the part number on the servo they are selling matches your car's specification. The i40 ran from 2011 to 2015 with a facelift around 2014, so clarify which phase your car is and which phase the donor came from. Engine size is the most important matching variable, so confirm petrol-to-petrol or diesel-to-diesel with the same displacement before committing.
