Hello together. I have some questions about MY 91: 1. Have you heard claims that MY 91 have weak chains and gears! Is this true? 2. Do you all have the original air filters or is there something better? 3. Does it come to which ignition box I use? (have any of MY 93 and MY 94) Are there any differences? 4. There was once a rear panel to MY 91 (picture) does someone else have one that you can buy?(of course, quite and not so faded! 5. What needs all around the world? Is it useful to have a cooling fan 2 Stufig? ( Relay power station in engine compartment F ) Is it useful to have it on board? 6. Unfortunately, my TCS has on board. Would there still have (from one I battles) a complete device without TCS. How much work is there such a conversion? Does it make sense? What has to be changed? 7. My climate compressor makes cymbal loud! Is it soon on the Ars..? Or is it normal with these JGs? So these would be my questions… Thanks already in advance Greetings from beautiful Switzerland Stefan
