Hello dear elk friends, after I spent some time in the SuFu on the topic of ZR-change and also found great contributions, I would like to know a few more questions: 1.) Does the sentence apply here as well: only original Volvo parts, or are the e.g. Skandix home brand parts also recommended? 2.) Which “special tools” or which tools do I need to simplify the work? 3.) Which additional works should I do right away (clearly WaPu times excluded)? 4.) Does the WaPu have to be “read” by the Volvo dealer by Pc? (have read what) 5.) Are there only English instructions? I refer to my elk here: C70I Turbo, 2.5L,193PS, Bj1999 Many greetings from Hessen Hessenelchc70
