Hello everyone! I have the following problem with my Tucson: For some time now (so 25 TKM) I noticed (and criticized it in the workshop) that he vibrates strongly in the cold state and hardly takes up 22.5 TUdr/min. That remained without finding out. This symptom has intensified in the course of the last weeks. My Tucson still drives with car gas. The system was installed by Hyundai and equipped with FlashLube. Since I had keum Flashube Vrebrauch, this was also done together with the Rucke Three weeks ago, the engine-control light lit up. A check in the Hyundai workshop showed that there was a misignition in the second cylinder. The ignition cable was then replaced there, because the old “no longer good” looked. Almost 500 KM later the car came for inspection and there it was found that there is no compression on the second cylinder and a damage in the cylinder head is suspected. My Tucson is now 21 months old and has run 60 TKM, also with autogas (without speed orgies and with FlashLube). My question/problem is: has someone ever had similar experiences or can someone give me a tip about what can happen? The autogas system was installed by Hyundai on the factory side, so there is no retrofit or similar and guarantee. At the moment I am a bit shocked that something like this occurs after 21 months and 60 TKM. Thank you for your help / tips! Best regards, Weber73
