Renault Kwid Engine ReplacementCompare Prices & Save

Replacing a Renault Kwid engine typically costs between £395 and £750 for the unit itself, with supply and fit adding £300 to £500. Total costs depend on whether you choose a used, rebuilt, or reconditioned B4D or B4A engine.

• Used B4D engines start around £250 to £450.
• Rebuilt units range from £395 to £650 supply only.
• Supply and fit services add £300 to £500 in labour.
• Reconditioned engines with upgraded parts cost £450 to £750.

Yes, if the replacement cost is under £1,000, it is usually worth replacing the engine on a Renault Kwid, given the car's low residual value. A rebuilt engine extends the vehicle's life for a fraction of the cost of a replacement car.

• A used Kwid is worth £4,000 to £7,000 depending on age.
• Main dealer replacements often exceed the car's total value.
• Independent specialist rebuilds keep costs below £1,000.
• A rebuilt engine with a 12-month warranty adds resale confidence.

The most common Renault Kwid engine problems include plastic oil sump cracking, sudden power loss from electronic throttle faults, and excessive vibration from worn engine mounts or balance shafts.

• Plastic oil sumps crack under heat or road debris.
• P0301 misfire codes point to failing ignition coils or injectors.
• Earthing wire faults can cause the engine to immobilise.
• 3-cylinder NVH leads to premature engine mount collapse.

The Renault Kwid B4D 1.0L engine is generally reliable for city use, but it suffers from specific weak points like the plastic oil sump and electronic throttle body that require monitoring to prevent catastrophic failure.

• The bottom end is robust if oil changes are frequent.
• Plastic sumps must be inspected for cracks or leaks.
• Electronic throttle bodies can fail around 60,000 miles.
• Upgraded aluminium sumps are available as a preventative fix.

While mechanically simple, fitting a Renault Kwid engine yourself is not recommended due to the need for ECU resets, immobiliser matching, and AMT gearbox calibration if applicable.

• The ECU must be matched to the immobiliser system.
• AMT variants require specialist gearbox calibration.
• Incorrect earthing wire connections cause running faults.
• Professional supply and fit includes all software resets.

Sudden power loss in the Renault Kwid 1.0L is usually caused by a failing electronic throttle body, a clogged fuel filter, or a P0301 cylinder 1 misfire code triggered by degraded ignition coils.

• Electronic throttle bodies fail and trigger limp mode.
• Fuel pump starvation causes cut-outs under acceleration.
• Ignition coil failure leads to severe misfires.
• A full diagnostic scan is required before replacing the engine.

The engine code on a Renault Kwid (e.g., B4D or B4A) is stamped directly onto the engine block, usually near the gearbox bell housing, and is also listed on the vehicle's VIN plate and registration documents.

• Check the VIN plate under the bonnet or on the door sill.
• Stamped on the flat machined surface of the engine block.
• Essential for ordering the correct rebuilt or used unit.
• Our registration lookup tool finds this automatically.

No, Renault Kwid engines (B4D and B4A) are unique to the Kwid's specific platform and are not interchangeable with other Renault models like the Clio or Captur, which use different engine families.

• The B4D is a specific 1.0L 3-cylinder for the Kwid.
• ECU mapping and mounting points are model-specific.
• Do not buy engines from other Renault models.
• Always verify compatibility using your registration number.
