Re: Repairing Headlamp Popup Motors

Hi,

I need to replace the inner gearwheel on my 91' - anyone having a broken motor but with functional inner mechanics that you want to get rid of? Or even better, a fully functional motor of course...

Re: Adjusting Idle speed

I'm bumping a 10+ years old thread :-) Regarding the wiring to the coolant temp sensor mentioned above. If one can read reasonable engine temp figures from info center - does that mean the sensor is okey? Or does those figures come from another sensor? I'm fighting a 1300 rpm idle and first just ass...

Re: Ignition

Hi, I have a very similar experience. I have two 480 turbos, one '91 and one '94. The '91 ignites immediately, but the '94 needs a fair amount of seconds to pump the fuel before it ignites. If re-started soon after being shut off, it goes quite quickly. But if it's been parked for a while it needs t...

Re: Strange speedo behavior

I figured I could share this find that came up on the local swedish eBay equivalent Tradera: https://www.tradera.com/item/343483/647423496/volvo-480-nos-kretskort-till-instrument If you need to repair the instrument cluster PCB but not fancy the soldering - here is a unopened PCB. Don’t know how old...

Re: Volvo HA-4140 Amp

Anyone that knows the difference between the ha-4020 and ha-4520?

According to old catalogues they look identical, both are 4x20 watts, but 4520 is for 480 only and the other for other models? What stops me from putting a 4020 in the car, as the 4520 is impossible to find?

Re: Strange speedo behavior

Hi, I had similar behavior with my 94. Combined with the fact that the speedometer barely never worked at all. I re-soldered all joints on the cluster PCB (as the guide on this forum says) and cleaned all connectors. Everything works like brand new now, and the dimmer doesn't affect the speedometer ...

Re: 480 Turbo Exhaust

Yeah, I guess you are right about those brands. The most expensive "cheap" one I found, was the Imasaf but I have no idea if that's because it's much better than the other brands you mention, or if they just charge more... This ie: https://www.ebay.de/itm/404344799657 Unfortunatly, the silences is b...

Re: 480 Turbo Exhaust

I bring this old thread back to life... I'm also in the need of replacing rear silencer, and I think the car would enjoy some fresh pipes all the way from the cat back (turbo-94) I've been in contact with CSC Marmitte but they say they don't have anything for 480 any longer (even tho it's in their c...

Re: Volvo Audio - What you never asked for....

Hi! I just managed to get my hands on a CR-905 for a nice top-of-the-line-oem-fit in my Turbo-94. The idea was to use the cd-changer connection for a hidden bluetooth functionality (as mentioned earlier in this thread). Anyone aware of what bluetooth adapter to use? I find the "Bluemusic" one on a f...
