Lotus Exige 3.5 V6 S3

The clutch itself is a conventional unit, but replacing it on the V6 Exige is expensive due to packaging. Lotus originally specified 36 hours of labor because the process requires clamshell removal and engine lift. Experienced Lotus specialists have reduced this to around 12-15 hours, bringing total cost to around £2,500-3,500 (€3,000-4,000) at a dealer. Independent specialists typically charge £2,000-2,500 (€2,500-3,000). Clutch life varies enormously with driving style: gentle road use can see 80,000+ km, while frequent track use or hard launches may wear a clutch in 40,000-50,000 km. Lotus updated the clutch and flywheel for the 400/380/410/420/430 variants with a stronger unit that is also a popular retrofit for earlier Exige S models.

Early Exige V6 models (approximately 2012-2014) had rear uprights that were prone to cracking. Lotus revised the part with additional material around the weak area during production, but never issued an official recall. Reports suggest more than 10 confirmed cases, some on low-mileage cars that were never tracked. The DVSA investigated but no formal recall was established. On affected cars the upright can fracture without warning, which is a serious safety concern. Check for the revised part number or inspect for any hairline cracks around the hub mounting. Replacement cost including the part and alignment is typically €800-1,500 per side, but if failure occurs at speed the resulting damage can be much more expensive.

The Eaton TVS1320 (or Magnuson MP62 on early cars) supercharger uses nose cone bearings and a coupler that wear over time. Symptoms include increased supercharger whine, rattle at idle, or grinding sounds under boost. A snout rebuild kit costs around €150-250 for parts, but requires a hydraulic press and expertise. Professional rebuild services charge €500-800 for the snout, or €800-1,500 for a full supercharger rebuild. This typically becomes necessary between 80,000-120,000 km. Superchargers Online is the only EATON-approved rebuild specialist. Catching bearing wear early prevents damage to the rotor pack, which would require a much more expensive full rebuild.

The IPS (Intelligent Precision Shift) automatic option uses a modified Toyota U660E torque-converter automatic. Known problems include random limp mode events where all dashboard warning lights illuminate and the car refuses to engage gear, wiring harness degradation causing intermittent sensor faults, and harsh downshift behavior when coasting. The transmission also operates near its torque limit at full throttle, so power is electronically restricted in lower gears. Wiring harness replacement sometimes resolves intermittent faults (€1,000-2,000), but if the transmission itself fails, a factory-rebuilt unit costs €5,000-8,000 including fitting. Manual gearbox cars avoid this issue entirely and are strongly preferred by most buyers.

The drive-by-wire throttle system can develop issues with the stepper motor connector, causing intermittent limp mode limited to 1,500 RPM. Fault codes P2104 and P2119 are typical. Often the issue is connector corrosion or moisture ingress rather than component failure. Cleaning the connector and applying dielectric grease resolves many cases for minimal cost. If the throttle body itself needs replacement, expect €400-600 for the part. In persistent cases, the wiring harness may need replacing (€800-1,200 including labor). Cold weather and cars that sit for long periods are more susceptible.

Early Exige V6 models had cooling fan bearings that would become noisy when the fans activated. Lotus addressed this with upgraded fan units, and most affected cars should have received the updated parts under warranty. If not already replaced, a pair of OEM Spal fans costs approximately €200-350, with fitting requiring a couple of hours of specialist labor. This is a nuisance rather than a reliability threat, but noisy fans can mask other mechanical sounds during inspection.

A well-documented issue across the V6 Lotus range. The brake pedal switch plunger sticks, triggering ABS fault code C0340 and illuminating the ABS warning light. Lotus issued Technical Service Bulletin SB-2015-03 recommending lubrication with silicone grease. The switch itself costs around €15-30 and replacement takes under an hour. However, if the ABS module itself has been damaged by repeated switch faults, replacement or repair of the Bosch ABS module can cost €800-1,200. This is a common and well-understood issue, so verify the switch has been serviced or replaced.

The Exige's bonded aluminium chassis uses steel inserts at suspension pickup points. Where dissimilar metals meet, galvanic corrosion can dissolve the surrounding aluminium, particularly on cars driven in winter on salted roads. The anodised coating provides some protection, but once breached the corrosion progresses steadily. Lotus does not approve structural chassis repairs, meaning severe corrosion effectively writes off the car. Affected areas include rear suspension pickups, front subframe mounting points, and sill rail joints. Cars stored properly and not driven in winter conditions are much less likely to be affected. A thorough underside inspection by a Lotus specialist is essential before purchase.
