Citroen DS Battery

I’ve known the battery was going out on my Citroen DS for a while. I had to start it on the jump pack after only a few weeks of inactivity, and my Ctek charger started to indicate it could not hold a charge. The existing Citroen DS battery had served me well for about 6 years. I like to get the biggest battery I can possibly fit in the space allocated. They last longer, and work better especially on a car like the DS which can be a slow starter with its mechanical fuel pump. The current battery didn’t take […]

Citroen DS Instrument cluster repair

Earlier in the week I had identified the lack of instrument cluster lighting was due to a crack in the instrument cluster circuit board. The crack was causing an intermittent broken circuit. I wasn’t able to find much on the internet about Citroen DS Instrument cluster repair. Looking at the board it looked like a very simple design. That gave me the confidence to come up with my own solution.

The easiest course of action would have been to solder a wire in place. I didn’t go with that approach as there is no soldering used on this circuit board […]

Citroen DS Instrument Cluster Lighting

Recently during a night drive I discovered my Citroen DS instrument cluster lighting had failed. In Sydney, where I live, this is a huge problem as the city is bristling with speed cameras. So many that I could lose my entire licence in about 10 minutes driving near my house doing only 10 km/h over the speed limit. I regularly drive at night, so I needed to find a solution.

My first assumption was the rheostat had failed. The rheostat is the dimmer that lets the driver control the brightness of the instrument cluster lights. Over time, these can develop […]

Citroen DS sphere pressure check

Today I attended a Citroen Car club tech day. Since most Citroens are equipped with hydropneumatic suspension, the club has equipment to pressure test spheres. It has been five years since I tested my spheres, so they were well overdue. The sphere pressure check equipment consists of a hand pump and pressure gauge. The club is also equipped with re-gassing facilities, although those were not available today for the rebuildable spheres in my DS21.

The tech day did have a hoist available, but my preference is to remove the spheres at home first. As with last time I removed them, […]

Citroen DS electric cooling fan

The Citroen DS cooling system is somewhat unique in that it relies almost exclusively on pulling air through ducting to cool the radiator. Most cars have a grille where the faster the car moves, the more air is pushed over the radiator. On modern cars this is the grille below the bumper. It is only at idle they only rely on pulling air through the radiator. The Citroen DS has a large plastic fan attached to the camshaft pulley. That fan sits behind the radiator and then pulls air through based on engine speed. The DS21ie and all DS 23 […]

Citroen DS Window rubbers and felts

After my Citroen DS was painted, there were a couple of cosmetic things wrong with the car that were far more noticeable. One of them was the DS window rubbers and felts. The previous owner had used generic units, and they didn’t fit all that well. Proper reproduction units are available, which are the right size and use the standard mounting points.

I didn’t get a chance to take before and and after photos, but the new DS window rubbers and felts look much better.

As well as the proper window rubbers and felts, the correct mounting hardware is […]

Retrosound Model 2 Repair

The Retrosound Model 2 radio in my Citroen DS has been playing up. It would randomly adjust the volume on its own, mostly down. The practical effect of this was not being able to listen to the radio. A while back I removed the face of the radio to take a look and the wire from the volume knob to the radio looked chafed. The face of the radio is separate from the main unit as there is not enough room in the DS to install it in one piece.

Retrosound sell replacement shafts so this seemed like a […]

DS Front End Repairs

A couple of months ago my DS had one of the front suspension boots replaced to cure a bad LHM leak. When this was done, it was apparent the bushings in the steering rack were worn. Since the front of the car was apart, it made sense to order these parts and then have them fitted before the front was put back together. I ordered the parts a few months ago, but for some reason Franzose sent them by the slow boat. This was rather irritating as the DS has been sitting partially assembled for months. Some of these repairs […]

Citroen DS under bonnet insulation

As my DS has a NOS bonnet, I did not want the hot engine to damage the paint. The Citroen DS under bonnet insulation not only protects the paint, but also reduces noise. I was also told that I was missing two brackets that help hold on the insulation.

I was able to purchase a good used pair of the brackets and have some help to get the bonnet off to install the insulation. It comes in three pieces so is quite easy to install. As can be seen in the picture, it does not cover the whole bonnet, as […]

Citroen DS front end wiring – part 5

After all my hassles with the DS wiring, I wanted a better solution. Not only were the existing bullet connectors old and brittle, but their colours had largely faded. Instead of replacing the bullet connectors with new ones, I decided to use multi-wire plugs. In this case, Deutsch connectors. Instead of eight wires on one side and six on the other, there would be a couple of simple connectors to unplug each time the wings are removed. On the DS, the wings are removed for many service jobs, so they come off every year or so.

 

I had […]
