Dear community, (maybe also the hangover is just around the corner…) my 2.3 Lpt model 2000 has now run 135,000. I can’t detect any oil-coking (test tip without oil tub disassembly came from the hangover). Now the chain gets loud. I assume that there is “normal” wear here. (…good at the 9000er it was 210000 in, a colleague got with his 9000er at 140000 ne new). Question: “Only the control chain with spanners renew or is there another program ?. Au f which costs can I be curious ? and what is there in addition to consider ? Repair will then be my friendly (free) Saab-Greek in Ludwigsburg. Greetings Jazzer 2004
