W124 - New Door Switches and Front Rotors and Brake Pads

So it's been some time since there was some work done on the car. My wife and I had pooled our funds and for another project hence the focus on the car has been reduced. Now that I have some time, the IBS kicked in and with some spare change, I decided to get some work done on the car. The focus is on the front brakes.

I was at the mechanic after a long time, over a month to be precise. I have observed that during braking of the car is juddering and slightly pulls to the left. After discussing with the mechanic, to which he has earlier prompted me that the front rotor needs replacement, it has worn thin.

So after discussing, we went ahead to get all the parts needed, a new pair of front rotors, brake pads, and the brake wear sensor.

When the rotors were removed, it was noticed that they were thin and it was dangerous to drive the car with that brake condition. We also noticed that the rotors appeared to have been skimmed. The OEM rotors were not meant to be skimmed, when it is work or warped, they need to be replaced. The brake pads were not too bad, but they need to be replaced as well since the rotors are being replaced. The front right brake sensor was not installed and the one on the left was broken. As a proper fix, all that needs to be replaced. It was also noticed that the calipers will not properly pressure and depress. The pivot screw seems to have lost all lubrication and a quick greasing sorted that. The last brake service and repair may have been a long time ago that it needs proper servicing.

It was about an hour's worth of work and the brakes were refreshed. The rear has been refreshed earlier, as in a few months ago, and is in good working condition.

While the mechanic was at it, I also got him to install the door switch for all doors. It was as simple as unplugging and locking it back in place with 2 wires attached.

As usual, the brakes are a little weak after a brake job until the new brake pads have bed-in properly. The observed juddering is no longer there.

The Rhino now has restored brakes and I am in a safer car.

New door switches from Hella, they are all the same for all the doors

W124 - Engine Wiring Harness Replacement

Image
Mercedes built from the year 1992 to 1997 was installed with an eco-friendly (degradable) wiring harness. The issue with this type of harness is that the insulation disintegrates and crumbles especially when exposed to heat. For the W124 model, it is safe to say that all cars built from the year 1992 onwards were marred with this issue, both petrol and diesel models. What is baffling is that Mercedes is aware of the issue but a safety recall was never issued to have the wiring harness replaced with a non-eco version. The intention of going green badly backfired as this issue introduces an array of problems on the car. The reason why this happens is that the insulation upon crumbling exposes the bare wire and when two or more of the bare wire touches one another, it messes up the communication to and from the ECU causing strange behaviors and in more serious cases, it causes fire. This issue was covered in length in the following links: http://badmercedes.com/ http://www.mercedesdefects...

W124 - Transfer of Ownership using MySikap

Executive Summary: A short entry on documents needed to obtain a copy of the VOC (vehicle ownership certificate) from the JPJ. Details: I was out at the JPJ to get the registration card, I think its now called the VOC. I have completed the online transfer of ownership via the MySikap portal and thought that all I needed to do was show up and present my IC to obtain the VOC. The Shah Alam JPJ was packed and I decided to go to the Shah Alam UTC instead. After queuing for about 30 minutes, my turn came up. At the counter, I was declined because I did not have the receipt copy for the transfer and photocopy of my IC. I was under the pretext that all that is needed is my IC and they should be able to see the transactions and details but apparently I was wrong. I will have to return to the JPJ again, to get the VOC and prepare all the required documents. In summary: If the transfer of ownership is completed online via the MySikap portal, keep the receipt and print them out Have a photocopy o...

W124 - Rust... No More and Hello Accurate Facelift Look

Image
Executive Summary: This entry is about the rust repair on the Rhino and also correcting the external trim to the correct facelift version for 1994 onwards made W124s. Details: When I bought the car, I was a W124 newbie and wasn't aware of where the rust spots are and what I should I be checking for. I tried doing my due diligence by checking on the real condition with the person who sold me the car based in Kampung Melayu Subang, K*****T Auto, but as shared in my previous post, don't expect a conman to be honest (by the way, stay away from dealing with this guy, stay very far away!). I was told it was in good condition and there are no rust issues and the body is in very good condition bla bla bla... a bunch of bullshit! I have requested an inspection of the body condition which was fair. There were rust and the rust was observed to be on the front passenger footwell, both sides of the rear spare wheel wells, a little on the rear left quarter panel, and the battery tray among t...
