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 19″ Black Monaco Mirabeau wheels

Found a nice set on eBay Kleinanzeigen for my Volvo S80 2.4T Wasa Limited edition. They are black 19″ inch Monaco Mirabeau wheels, which fit the black Volvo great. Very happy with them 🙂

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 New Bosch O2 Lambda Sensor

As a car grows older, parts outreach their peak efficiency and should be replaced with new parts. Like the front O2 lambda precat sensor, which has an replacement interval of 250.000km, which my car already replaced sometime ago. Replaced it with a genuine Bosch OEM part. Noticed that my Long Term Fuel Trims (LTFT) were dropping, which is a good indicator.
