On the 1999-2000 Volvo S70, the S70 ETM (drive-by-wire throttle body) develops internal contact wear causing intermittent stalling, reduced power mode, and check engine light. This was subject to a Volvo extended warranty and is one of the most common P2 platform failures.

Common Symptoms

  • Reduced power mode
  • Stalling
  • Check engine light
  • Rough idle
  • Throttle not responding

On the 1999-2000 Volvo S70, if your 1999 or 2000 Volvo S70 lights a warning lamp and then suddenly restricts itself to limp home mode, NHTSA recall 06V441000 is worth checking. Volvo reported that throttle position sensor irregularities, a dirty throttle housing, and/or inefficient software calibration — alone or in combination — could trigger the warning lamp and the limp home mode that follows. The stated consequence is that a high number of vehicles went into limp home mode without need, so S70 owners experienced the drivability restriction even where the condition did not warrant it. The recall was filed under the Vehicle Speed Control component and opened December 29, 2006. The 170,099-unit figure attached to the campaign is the total across every vehicle in the campaign, not an S70-specific number.

Common Symptoms

  • Dashboard warning lamp comes on
  • Vehicle enters limp home mode
  • Loss of normal throttle response / restricted power

How to Fix

Volvo's remedy, performed free of charge at a dealer, is installation of the current software upgrade on the affected vehicle. Because this was a 2006 campaign, many cars have already had it done — check your VIN at nhtsa.gov/recalls to see whether 06V441000 remains outstanding on your S70, and contact Volvo at 1-800-458-1552 or a Volvo dealer to schedule the reflash if it does.

On the 1998-2000 Volvo S70 5-cylinder, the Volvo S70 turbo and non-turbo 5-cylinder engines develop PCV (Positive Crankcase Ventilation) system blockage. The breather box/flame trap clogs, causing excessive crankcase pressure that pushes oil past gaskets and seals.

Common Symptoms

  • Oil leaks from valve cover
  • Oil consumption increase
  • Oil residue around turbo
  • Whistling noise from engine
  • Rough idle

How to Fix

Diagnose the PCV system by checking for excessive crankcase pressure at the oil filler cap or dipstick tube, then inspect the breather box/oil trap, flame trap fittings, and all related vacuum hoses under the intake manifold for sludge blockage or collapse. The proper repair is a full PCV service kit installation—typically replacing the oil trap, banjo fittings, hoses, intake manifold gasket, and cleaning the ports in the block and manifold; on turbo models, also inspect and clean the turbo oil return area and replace any leaking cam, valve cover, or rear main seals only after crankcase ventilation is restored. If oil leaks have been present for a while, recheck for residual seepage after the PCV repair before replacing seals unnecessarily. Typical cost is about $250-$450 in parts and 4-7 labor hours, for a total of roughly $700-$1,400 depending on engine configuration and how many oil leaks need follow-up repair.
