Moin, my 850 doesn’t get a Tüv at the moment. Reason: All brake lines have been faulted – Execution inadmissible. Because: consist of CuNiFer, and these have been inadmissible since 1994. Only those of OJD/QuickBrake with ABE are allowed if registered. Their lines are marked. Volvo original lines are not marked. There is from the Volvo homologation department the document B0004 IM from which shows that all x70 and the S60/S80/V90/XC90 of the first generation ex works with lines are equipped with a copper alloy, which have NO markings, and also that original spare parts have no markings. Only: Unfortunately this helps absolutely zero if on the document of the 850 does not stand, even if the spare parts numbers are the same between the vehicles. If at least by the KÜS is not recognized, I just phoned with their head office, and now comes: They have in their database for NO vehicle of Volvo a corresponding certificate, the s is installed there ex factory CuNiFer, and the original spare parts are made of the same material. That means, if the examiner now criticizes the pipes and you would repair everything with original Volvo spare parts, then the examiner would be according to those in law continue to reject the repair as inadmissible. As a customer, you have to prove that this execution corresponds to the standard condition and is permissible, not the testing organization. Volvo (because this type of line has been used since the 200s) could be pulled out of circulation during a test at the KÜS without any prospect of “healing”, unless you buy replacement brake lines from OJD/Quickbrake and have them assembled. These come – just like the original Volvo spare parts – as cut-off ring products, therefore, also have to be bent first. Exactly what the “obviously manually bent” the examiner criticized at mine, and brought him to the conclusion that that can’t correspond to the original. So, look for your test organisation for old Volvos exactly, and if necessary don’t go to the KÜS, because they don’t have any information about the lines in their internal system. Since an examiner has been involved in a faulty HU certificate since 2018 because of a criminal offence (before that was only a simple offense), many are also rather narrow in terms of the interpretation of the regulations of their test organisation.
