Hello dear Volvianer, since yesterday I am in possession of a 1998 S40 2.0T. I now have some questions/problems: 1. Tempomat does not work. So not at all. After the fuse we have already looked, which looks good. 2. The radio. I have upgraded the original SC-802 and my JVC radio installed. However, it does not save the settings. I have tried various wirings already, but with the original wiring the radio does not work at all. Now we have bought a double DIN from Kenwood and there it works just as little with the storage. Can this possibly be on the adapter from the original cable tree to ISO? 3. Brumbing and roaring in the interior. At speed <1600 and >3000 it is very noisy in the car. I think it comes from the exhaust system. Do you have perhaps another idea? On Tuesday I have an appointment in a workshop. The master at that time has learned himself from Volvo and perhaps knows some tricks and tricks. But I wanted to get the opinion of the old Volvo driver.
