I have a V50, model 2010, 2.0 Flexfuel, with 68,500 km of mileage. My elk has been having a restless idle for several months now, which expresses itself as follows: Speed remains stable and immediately but as soon as the engine is warm, after about 10 km of drive, then the engine trembles in the stand, after longer highway rides it has quasi chills, which is not only scary, but more than annoying. The start behavior in cold and heat is completely ok, as well as the gas acceptance, the passage and the max. speed likewise. There are no problems. Here the list of works, which have already been carried out in 5 workshops, of which 2 x the friendly, 1 x Bosch and two free, but which have immediately waved off. Error memory repeatedly read out and deleted, no faulty entries present test on allg. Andichten, all o.K. Zündkerzen have been changed by now 2 x. Zündspulen have also been cleaned by Drosselklappe valve play has been checked => i.O. Compression has also been updated.
