OK here is the "newly" replaced instrumental cluster. Everything is working just like it should except for a few errors on the central LCD. One thing I am a bit confused was the "Hydraulic Oil Level" error. I am surprised to see this error because it wasn't on my original instrumental cluster error. So I did some digging online and found out the the hydraulic system was only fitted in a wagon W210. The hydraulic help to maintain the ride height in the even of heavy load on the rear boot.
I checked my eBay purchases regarding about this instrumental cluster and found out it was taken out from a wagon W210. So now I learned that old error from old car will be memorized in the instrumental cluster.
There is no way I will be able to delete the error. We will see how it goes in the future. I might just put back my old instrumental cluster and replaced only the moldy plastic covers.
Here are two more errors that has been popping out for a few years. There are the ASR and ABS. There are many reasons for these two errors so a proper diagnosis will be in order after I fixed the engine shaking problem. Thanks for reading!
