Hello! After my dealer has been searching for my speed fluctuations for a long time now to the probable cause (allegedly the injection nozzles and too high injection times of up to 45ms), the question arises, how I should best proceed, in order as “unsuspected driver” not to pay again 2 injection nozzles are allegedly no longer in order. The workshop wants to exchange all 6 of course as already expected, the material would be at € 3.700,00 – find something For me it would be logical to fix only the 2 defective ones, or if possible to clean them, the other 4 should still be fine. Is there any experience and has someone renewed the nozzles before? I still have a guarantee with self-reservedness, but the economist in me still refuses to make everything new at once. Thank you and dear greetings, Pete
