Common Problems
Fiat 124 Engine Problems - What It Costs to Fix & When Replacement Makes Sense
The Fiat 124 Spider's 1.4L MultiAir turbo petrol engine is generally robust but has three well-documented failure patterns driving UK replacement enquiries: timing chain tensioner wear, MultiAir hydraulic actuator degradation, and turbo wastegate faults. Every rebuilt engine supplied through EngineMarket includes upgraded internal components designed to...

Failure mileage range
70,000-100,000 miles
Typical failure window
Root cause
Early-production tensioner design allows chain slack under cold start, causing rattling and potential skip.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Preventative Tensioner Replacement | £800 - £1,200 | £500 - £800 | Replace tensioner and guides before chain skip occurs | Viable only if caught early; does not address actuator wear |
| Full Replacement - Rebuilt / Reconditioned Engine | £3,500 - £4,500 | £2,400 - £2,800 | Supply & fit rebuilt unit with upgraded tensioner, bench tested, 12-month warranty | Best value for high-mileage or already-failed units; addresses all wear points |
Our recommendation
If your Fiat 124 is under 80k miles and only showing early rattling, a preventative tensioner replacement from a specialist can extend life cost-effectively. For units over 90k miles or with confirmed chain skip, full replacement with an upgraded rebuilt engine is the only reliable long-term solution.

Every displacement fitted to the Fiat 124 Spider is listed below, with compatible engine codes, production years and common failure notes to help you identify the right replacement.
The 1.4L MultiAir turbo petrol engine powered every UK-market Fiat 124 Spider from 2016-2020, appearing across Classica, Lusso, Lusso Plus and Abarth variants with outputs from 140hp to 170hp. This compact forced-induction unit combines Fiat's hydraulic valve actuation technology with a Garrett turbocharger for responsive performance, though early-production units require attention to timing chain tensioner and MultiAir actuator maintenance.
