Most Fiat 124 Spiders use the 379A0001 series MultiAir turbo petrol engine code. Enter your registration above to instantly verify your exact code via DVLA.

• Base code 379A0001 fitted to Classica and Lusso 2016-2020
• Revised codes 379A0001A-E denote production updates and Abarth spec
• Engine code stamped on block near timing cover and in DVLA record
• Abarth variants use 379A0001B with upgraded turbo components

The 1.4L MultiAir turbo is generally robust but has three documented failure patterns: timing chain tensioner wear, hydraulic actuator degradation, and turbo wastegate sticking after 80k miles.

• Timing chain tensioner rattling reported on early-production 2016-2017 units
• MultiAir hydraulic actuator (04462743AB) seals degrade after 60-90k miles
• Turbo wastegate sticking causes P2262 codes and boost loss on high mileage
• Late-production 2019-2020 models incorporate all prior reliability fixes

Engine replacement on the Fiat 124 Spider is a complex job requiring specialist tools, ECU coding equipment and alignment expertise - professional fitting is strongly recommended.

• Engine removal requires transmission separation and subframe support
• MultiAir system needs hydraulic calibration after installation
• ECU immobiliser coding requires dealer-level diagnostic equipment
• Incorrect fitment can void warranty and cause drivability issues

Every rebuilt or reconditioned Fiat 124 engine supplied through EngineMarket includes a minimum 12-month unlimited mileage warranty from vetted UK specialists.

• Minimum 12-month unlimited mileage warranty standard across network
• Some suppliers offer extended 24-month coverage at premium price
• Warranty covers parts and labour when fitted by network specialists
• Always confirm exact terms with your chosen supplier before ordering

Supply-only engines typically dispatch in 3-5 working days; full supply and fit appointments require 1-2 days workshop time plus pre-booking lead time.

• Rebuilt engines usually ready for dispatch within 3-5 working days
• Supply and fit appointments require 1-2 full workshop days
• ECU coding and road test add 2-3 hours post-installation

Yes, provided the replacement engine matches your vehicle's emissions standard and is correctly coded - all network engines are MoT-compliant.

• All Fiat 124 Spider engines are Euro 6 emissions compliant
• Replacement engines must be correctly ECU coded for immobiliser match
• Emissions testing requires proper catalyst and O2 sensor function
• Network suppliers provide compliance documentation for MoT centres

Yes, all Fiat 124 Spider petrol engines meet Euro 6 emissions standards and are ULEZ-compliant for London and other clean air zones.

• 1.4L MultiAir turbo petrol engines meet Euro 6 emissions requirements
• No additional charges for London ULEZ, Birmingham CAZ or other zones
• Replacement engines retain original emissions certification

Yes, a standard Fiat 124 can be upgraded to Abarth-spec 170hp using the 379A0001B engine code, but requires ECU remap, exhaust and suspension modifications for full compatibility.

• Abarth-spec 379A0001B engine includes upgraded turbo and intercooler
• ECU remap essential to unlock full 170hp output and correct fueling
• Exhaust system and suspension upgrades recommended for balanced performance
• Specialist installation required to ensure reliability and warranty validity

Rebuilt engines replace worn components with upgrades; remanufactured units are restored to factory spec with new parts; used engines are second-hand with variable history and mileage.

• Rebuilt: worn parts replaced, known failures addressed, best value balance
• Remanufactured: factory-spec rebuild with new components, premium pricing
• Used: lowest cost but requires compression test and history verification
• All network rebuilt/reman units include 12-month warranty; used engines vary
