Mini Cooper S R53 JCW – Injector Service

Cleaned & replaced the rubbers on the blue 380cc Siemens Deka injectors. The rubbers tend to get hard and brittle due to heat, so very important to replace these in time.

I will probably replace the injectors somewhere in the near future for peace of mind.

Mini Cooper S R53 JCW – Servicing the Eaton M45 supercharger

When I bought the Mini, it had reached the 160.000km or 100.000 miles mark. This is a milestone in the Mini Cooper S service history, because it means that you need to service the Eaton M45 supercharger (new fresh supercharger oil etc etc).

I saw the episode from Wheeler Dealers and felt confident. It was a lot of work, but fortunately it wasn’t complex. As this isn’t my daily driver, I meant I could take the time.

Volvo S80 2.4T Old Key to Flip Key

Bought a flip key on Aliexpress and went to the key service to get it working. Looks much better and takes less space in pockets etc.

Highly recommended modification!

Volvo S80 2.4T PCV DIY Repair / Service

Repaired / cleaned the PCV circuit as I saw a lot of oil in the pressure circuit (also see my previous post: https://www.ducked.nl/blog-entries/volvo-s80-2-4t-dirty-clean-turbo-coldside/ ).

Did a little research and the PCV system is almost always the culprit for such issues.

Decided to buy a complete system although ended up cleaning the existing system and only replacing the oil seperator. The tubing was quite some work, I will save that for another time.

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
