Volvo S80 2.4T Prancing Moose Decal

Bought me some yellow Prancing Mooses / Moose decal as it’s a Volvo thing to do 🙂

In the meantime, they have been replaced by black “carbon” units, which look better. This will be shown in a later post.

Volvo S80 2.4T Changing the Interior Combo filter

Needed to change the interior / combofilter and was suprised by this malformed unit.

Looks like someone didnt do their job properly…Shameful really.

Easy DIY job, which shouldn’t take more than half an hour.

Volvo S80 2.4T Black Flyeyes Wrapping

I had some Flyeyes wrap hanging around and decided to test it on the running light and the indicator side lights.

I forgot that I had some black wrap lying around and started off with anthracite wrap, which I re-did in the end. Very happy with the results, and it customizes the car a little bit more, which is exactly what I want 🙂

Volvo S80 2.4T Denso Injector Service

Decided to clean and service the stock Denso injectors. Rubber rings get hard and brittle over time and tend to leak. Also the filter baskets might be contaminated over time, especially if the fuel filter is not part of your regular service intervals (which mine S80 lacked…).

I bought this kit of Aliexpress and the quality looks very nice. It contains all the items needed, including a special tool for removing/mounting the filter baskets.

The pictures will speak for themselves (it was needed!).

Volvo S80 2.4T Modified Center Silencer

When I had the OEM exhaust, I wanted to have the center silencer removed, as the OEM exhaust is very good in keeping the car silent. But this car needs to make a little noise, so I decided to modify the stock middle pipe.

Gives a little bit more sound, without being to loud.

Also weighed it, and it weighs a mere 6.7KG .

Volvo S80 2.4T Polyurethane Lower Gearbox Mount

My original gearbox mount was shot and I decided to replace the mount with a brand new reinforced polyurethane mount, which tightens up the shifting and allows for less engine movement, which is better for the exhaust.

One disadvantage, the cabin has added drone due to extra vibration. But the advantages outweigh the one disadvantage, so for me it’s a keeper!

Volvo S80 2.4T Hella Style Horns

Wanted to see if the Hella style horns would fit the S80. First I painted them white (they were green). Mounting them was easy, but the front looks messy with the horns mounted, so I decided to remove them again.

Volvo S80 2.4T Changing Spark Plugs (NGK K20TT 4604)

Fitted some fresh new plugs and decided to try NGK copper plug instead of Volvo OEM Iridium plugs. They work great and cost next to nothing. Decided to try NGK K20TT 4606. Double checked the gap to be sure, they are correctly preset for the Volvo S80 2.4 / 2.5T.

Still have to get used to swapping out 5 spark plugs instead of the “usual” 4.

Volvo S80 2.4T Alarm Siren Module fix

As a lot of older Volvo’s, my S80 showed the cumbersome “Alarmservice needed” message. I decided to search for a fix instead of buying a new one, which costs about €280 – €300, which is a lot of money.

The process is very simple, slicing open the siren, disconnecting the battery pack and plugging in the new battery pack. The hard part is to remove the security bolt, I used a angle grinder and then tapping it out. I used a normal bolt when I mounted the siren again.

I bought it here: https://www.ebay.com/itm/152151139597

Volvo S80 2.4T Do88.se Blue Silicone Intercooler Hoses

Replaced some old deteriorated intercooler hoses with new fresh Do88.se blue silicone hoses, which do not collapse anymore. I solved a hiccup when flooring the car from low rpm (due to sturdiness of the new hoses).

Volvo S80 2.4T Polybush Gearbox Mount

My front gearbox mount was shot. Found a polybush replacement part which is a easy swap. Remove 4x 18mm bolts, swap the part and tighten the 4x 18mm bolts. Noticed a big improvement in pickup and shift handling. The engine/gearbox is able to move much less, which helps in driveability.

Volvo S80 2.4T Fitting a new Compressor Bypass Valve (CBV)

I noticed some strange behaviour when lifting the throttle and decided to service the CBV aka Compressor Bypass Valve. I was right, car drives a lot better after replacing it with a fresh CBV / DV (Diverter Valve).

I went with an aftermarket TRITDT K5T09671.

Volvo S80 2.4T Trying Out An Open Cone Filter

I wanted to try an open filter, to hear the induction sound and the blowoff sound. I went with a big velocity stack type filter. Although it sounded nice, I already reverted it and went back to the original airbox.

Volvo S80 2.4T Replacing Window Sliders

Easy mod with big results. If you have a Volvo with a choppy window, 9 out of 10, it will be the window sliders. They are quite easy to replace though. Tip: buy them on Aliexpress for cheap!

Volvo S80 2.4T Replacing the Bosch O2 Lambda Sensor

Many people tend to forget that O2 aka Lambda sensors have a replacement interval (in my case 250.000km). Failing to do so will have direct impact on your power and mileage. I checked using Torque (Android app) and checking the Long Term Fuel Trims (LTFT). I noticed that they dropped after installing the new Bosch O2 sensor.

Volvo S80 2.4T Replacing vacuum lines with Silicone Hoses

A highly recommended repair / modification for all older Volvo owners. Replacing the old rubber vacuum lines with strong durable silicone hoses. I bought 3 color hoses (red / black/ blue) as the original hoses also have color stamps on them. Old rubber hoses deteriorate from heat and moisture and will fail over time. Replacing them with silicone hoses ensures a proper running car!
