Same ETM failure as other P2 platform Volvos. The early C70 (1998-2005, first gen) is most susceptible.

This issue also affects: Volvo S40, Volvo S60, Volvo S70

Common Symptoms

  • Reduced power mode
  • Stalling
  • Check engine light

How to Fix

Confirm ETM failure by scanning for throttle-related DTCs such as P0121, P0221, P2135, or limp-home faults, then use live data to verify erratic throttle angle signals and inspect the ETM connector and wiring before condemning the unit. On 1999-2001 cable-throttle transition and early ME7-equipped C70 models, the usual fix is replacement of the original Magneti Marelli electronic throttle module with the updated Volvo unit or a professionally rebuilt contactless-sensor ETM, followed by software download/adaptation with VIDA/DiCE. Clean the throttle bore only if carbon buildup is minor; cleaning will not repair worn internal position sensors. Typical repair cost is about $700-$1,400 depending on whether a new OEM ETM, rebuilt unit, and dealer software reload are required.

The timing belt tensioner and idler pulleys fail, potentially causing the timing belt to slip or break. The 5-cylinder turbocharged engines are interference designs, meaning a broken belt results in catastrophic valve damage. Must be replaced on schedule.

This issue also affects: Volvo 960, Volvo XC60

Common Symptoms

  • Squealing from timing cover
  • Belt shows cracks
  • Engine won't start after high mileage
  • Ticking noise from front of engine

How to Fix

Replace the timing belt, tensioner, idler pulleys, and water pump as a complete kit every 70,000 miles or 7 years. Do not skip or delay this service.

Volvo recalled 1999-2002 C70 coupes and convertibles under NHTSA campaign 06V441000, filed under Vehicle Speed Control. According to the recall record, a combination of throttle position sensor irregularities, a dirty throttle housing, and/or inefficient software calibration can illuminate a warning lamp and then drop the car into limp home mode. NHTSA notes the result was a high number of vehicles entering limp home mode without need — meaning a C70 could cut itself back to reduced-power operation even when nothing was actually wrong with the car. The campaign as a whole covered 170,099 vehicles across all of the Volvo models included in it; that figure is campaign-wide and is not a count of C70s. The recall began on December 29, 2006.

Common Symptoms

  • Warning lamp illuminates on the dash
  • Car drops into limp home mode
  • Reduced engine performance with no other apparent fault

How to Fix

The recall remedy is free at any Volvo dealer: the dealer installs the current throttle control software upgrade on the vehicle. If you own a 1999-2002 C70, enter your VIN at nhtsa.gov/recalls to confirm whether campaign 06V441000 is still open on your specific car, then book the software update with a Volvo dealer. Volvo's owner line for this campaign is 1-800-458-1552.

The second-generation C70's retractable hardtop relies on a complex hydraulic system that is prone to failure. Hydraulic lines develop leaks, the pump can fail, and the microswitches that sequence the roof operation wear out. A single failed sensor can prevent the entire roof from operating.

Common Symptoms

  • Roof stops mid-operation
  • Hydraulic fluid leak in trunk area
  • Warning message about convertible top
  • Roof fails to latch securely
  • Slow or jerky roof movement
  • Clicking noise without roof movement

How to Fix

Diagnose which component has failed using Volvo VIDA diagnostic software. Common fixes include replacing hydraulic lines, the hydraulic pump, or individual microswitches. Hydraulic fluid should be checked and topped off regularly.

Owner tips & cautions

  • WarningNever force the roof if it stops mid-cycle - this can cause additional mechanical damage
  • TipCheck hydraulic fluid level in the trunk-mounted reservoir monthly during convertible season
Typical repair cost:$500 - $3,000

The second-gen C70 (2006-2013) retractable hardtop mechanism is complex with multiple hydraulic cylinders, latches, and sensors. Failures in any component can prevent top operation.

Common Symptoms

  • Top not opening/closing
  • Error message on dash
  • Top stuck partway
  • Hydraulic fluid leak

How to Fix

Begin diagnosis by scanning the Roof Control Module (RCM) and Central Electronic Module (CEM) for convertible-top fault codes, then inspect the trunk divider switch, latch microswitches, position sensors, wiring at the decklid hinges, and hydraulic pump/fluid reservoir in the left trunk area. Repair commonly failed items such as leaking hydraulic cylinders/lines, faulty latch motors or microswitches, and damaged harness sections, then refill/bleed the hydraulic system and perform the top initialization/calibration procedure with VIDA. Minor switch or sensor repairs may cost about $150-$400, while hydraulic cylinder, pump, or latch repairs commonly run $800-$2,500 depending on which components have failed and whether interior trim/top linkage removal is required.

Typical repair cost:$500 - $3,000

The Aisin-Warner automatic transmission develops harsh shifting and delayed engagement due to worn solenoids in the valve body. The transmission fluid change interval is often exceeded, accelerating wear.

This issue also affects: Volvo S70, Volvo V70

Common Symptoms

  • Harsh shifts
  • Delayed engagement from park
  • Slipping between gears
  • Transmission warning message

How to Fix

Replace the transmission solenoid pack and fluid. A valve body rebuild may be needed if solenoid replacement alone doesn't fix the issue. Change transmission fluid every 40,000 miles going forward.

Typical repair cost:$400 - $1,500
