Bought our 2002 2.2l Auto SLX in 2007 at 20,000 miles, with 1 year warranty, from a Citroen dealer. No work had been done to the brakes. A couple of months before warranty end (around 10,000 miles later), rear brakes started squealing. Predictably, "It's not bad enough to fix under warranty, sir"! Around 43,000 miles, I decided to overhaul them myself. As expected, rear pads had the usual "tilted" wear. When I spoke to the garage, they said I would have a difficult time removiing the bolts, and may snap them. In fact, they were fairly easy to remove. I cleaned Loctite from the bolts, "drilling" it from calipers holes, and cleaned up caliper and hub faces, Each face was "copper" greased and refitted, with correctly torqued bolts, using gaskets made from thick polyurethane sheet. Each bolt had the shaft copper greased and thread lock applied to the end thread. New pads and discs were fitted all round. These remained until 88,000 miles, when both front and rear pads were replaced. The wear was completely even on all the rear pads. 99,000 miles arrived, where I changed front discs and obviously fitted new pads. On inspection, rear pads were hardly worn and still wearing evenly. The mileage is now 123,000, and has recently passed it's MOT. If you spend a little time making the "Gaskets", you can save a lot of trouble in the long run. I did the same with the gaskets/copper grease/thread lock on our V6 and Activa Xantia's. I don't know why Citroen didn't do it.

I have a 2002 2.2 Auto. Owner's Handbook: The remote control must be reinitialised after changing the batteries. For that, switch on the ignition and then press one of the three buttons of your remote control. Remote control battery used up Accompanied by an audible signal, this information is provided by a message on the multifunction screen.

Seals are easy to change, if the injector comes out easily.

The problem with only one oil drain, is there is a lot of old oil still left in the box. For example, in the case of the 6 speed AM6 gearbox (see above), 3 litres drains out and 4 litres of dirty oil are left in. So less than 50% changed. Someone on the 406 Coupe club website calculated how many times you need to drain/top-up, before you approach a 100% change. When I did the change on my C5 2.2 auto (4HP20), I did 3 changes: 1st drain 4 litres approx. (including engine cranking). 2nd drain 3.75 litres approx. (no engine cranking). 3rd drain 3.75 litres approx. (no engine cranking). Each drain was into a measuring jug and left to cool to ambient temperature (same as new bottle of oil) before marking level on jug. Old oil emptied and jug wiped clean, then new oil poured into jug to marked level, prior to filling gearbox. This saves having the gearbox oil at a specific temperature to measure the oil level. Then driven for around 300 miles before 2nd change. Above repeated for 2nd and 3rd changes.

I own a 2014 C4 II Exclusive 1.6 e-Hdi manual, and have now done 4,000+ miles. Whilst gentle, steady braking is fine, firmer pressure on the pedal seems to give a disproportionate increase in retardation, resulting in excessive "nose-dive". In my opinion, either the brake servo gives too much assistance, or the pads are too "soft". It may be that a "harder" pad would improve the brake feel. Having driven many Makes/Models of cars in the last 50 years, I can honestly say these are the most unprogressive brakes I have experienced (and that includes owning a new Citroen GS Pallas years ago and our current C5 for the last 100.000 miles!). Having said that, I think smoother braking has improved a little over the 4,000 miles, either by the pads bedding in, or, more likely, getting used to/making allowances for them.

I had a similar problem with my Mk1 C5, Citroen say "filled for life" and various Dealers didn't seem to have a clue. Mine has the ZF 4 speed auto-box (4HP20), so I emailed the manufacturer (ZF), and their reply was: "Your 4HP20 transmission takes ZF takes Lifeguradfluid5. Although the gearbox is "filled for life", we recommend an oil change at 60,000 miles." If you can establish what the transmission model number is and manufacturer (I got mine by visiting a Citroen dealer with the VIN number), then we could probably help further.

Thanks, PM sent.

Edited by paul.h 8/6/2013 so it still made sense since the pictures would not attach . Following is based on the Citroen procedures: Refilling - Topping up the oil level : automatic gearbox HP20 (AG) 1. Recommended tools [1] hose clip pliers 4517-T (kit 4507-T). [2] topping up cylinder (-).0341. [3] Special adaptor to fit the filling hose from the cylinder into the air vent hole (-).0341 B. 2. Refilling 2.1. Oil capacities Dry gearbox oil capacity : 7,7 litres (minimum) 8,3 litres (max.). Oil remaining after draining : 4,7 litres (minimum) 5,3 litres (max.). Quantity of oil to be replaced : 3 litres (approx.). 2.2. Refilling Remove : - The air filter casing - The air vent assembly ( 1) on top of the gearbox and its plastic cover (2) from the gearbox using hose clip pliers [1]. Fill or top up Using tools [2] and [3]. Refit the metal part ( 1) of the air vent Using a Ø 18 mm drift and a hammer. Clip the plastic part ( 2) onto the air vent. N.B. : The gearbox air vent is available from Replacement Parts. 3. Topping up the oil level 3.1. Prior conditions Vehicle level , Handbrake off. Engine idling, without consumers (air conditioning, heating, etc). Check that the gearbox is not in downgrade mode Using a diagnostic tool. Apply the brakes firmly and move the lever through the various selector positions. Lever in position P. The check is performed when the oil has reached a temperature of 55°C ± 1°C Using a diagnostic tool. 3.2. Check the oil level Remove the oil level plug ( 3) on the side of the gearbox. 3.3. Draining of oil via the oil level hole When the oil temperature reaches 60°C ± 1°C, replace the filler plug (3). N.B. : The oil level is correct. Tighten the cap (3) to 25 Nm. 3.4. No draining of oil via the oil level hole Refit the oil level plug ( 3). Stop the engine. Remove the gearbox air vent assembly Using tool [1]. Add 0,5 additional litres of oil in the gearbox Using tools [2] and [3]. Repeat the top-up procedure. Remove tools [ 2] and [3]. Refit the metal part ( 1) of the air vent Using a Ø 18 mm drift and a hammer. Clip the plastic part ( 2) onto the air vent. Refit the air filter housing.
