hello… first of all thanks for the answers to the last question regarding the parking aid! I know the topic chip tuning has been discussed here so many times, but somehow never such a one really got to the point 🙂 with me still the question in the room, who takes over the guarantee?! give e.g. heico or MR etc. only guarantee on your chip or on the entire modo-infected motor?! which guarantee by volvo expires if a tuning is made!? as possible so far I have looked at WKR, heico, MR in Germany and bilsport in Switzerland. should I have overlooked important established and reliable tuners?! experience and impressions of chipped D5s were here already from time to time but I like to read them again 🙂 the dear D5er elch will be our first diesel and even if the first chip tuned vehicle, when he finally comes the next week… which general drivers exist at chip tuning. so a ls gray haunted stories are always motor damage, limited running time, restless running of the engine and other things in the room. maybe you just send me your impressions and experiences again and then maybe you can make the decision to give my elch a little power… thank you, and a beautiful Sunday philipp
