On the 1999-2005 Volvo C70, 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.

On the 1998-2002 Volvo C70, 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.

On the 1999-2002 Volvo C70, 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.
