• VW Sharan 2011 - Turbooverboost/DPF problems 15 Apr 2019 (Forum)
    After this the car was still going into limp mode, so the garage put another 2 turbos in, with the code then saying underboost. Still engine light would come on and go into underboost.  The garage now thinks the DPF needs replacing.  They removed the "I think" the lambda sensor, which on a test drive allowed the car to generate full power. They have tried a force regen but the car won't have it. At no point in owning the car (only 1 year) have we seen the DPF light, and whilst we do do short journeys I drive it high revs for periods to what I thought was encourage an active regen.
