People love it because the car is a little rare, not just in the UK, but across the world. It seems super hyper cars are popular but so are rare cars possibly within reach of most normal humans. Also your theory about the gas and regulation does make sense. I doubt they would've built such a complex system to allow for loss of gas, as it could be wildly different from each sphere. It would only take a small change in PSI for the effects to be felt. As for oil, I've seen much worse. Great video, and your humour/sarcasm makes for good viewing.

[@UPnDOWN]

Exactly. They couldn't plan for a gas loss as there are too many possible combinations.

[@paultaylor9652]

It's a shame Citroën/Peugeot don't build cars any more, they say the new 408 is going to be the saloon reinvented, what the people want the manufacturers build I guess. Great video again, more BX content would be appreciated.

[@556johny556]

The 408 has actually been already unveiled and honestly to me it's just an uglier Citroen C5x, or it's basically just Renault Arkana from Peugeot. In other words, nothing reinvented yet again.

[@TassieLorenzo]

Yeah, it's a shame. Mercedes and Hyundai have both realised ultra-aerodynamic electric sedans (or liftbacks) recently. I think the original DS reimagined as an ultra-aerodynamic electric car would be a wonderful thing (with hydractive suspension of course). It was never really known for the engines (AFAIK), so being electric would be perfect. As it is, the actual DS9 that exists is such a boring three-box saloon, what's the point of it?

[@Teribus13]

A general rule of thumb I use when changing paper element oil filters is that if the filter housing points upwards, as it does in your C6, then it's very likely that it'll dribble oil into the sump as you undo it. With that design I always change the filter before I drain the oil.

[@MrManBuzz]

The procedure I do is undo the filter housing a few turns which lets it drain, then drain the oil. By the time the oil has drained the filter will have drained as well which lets you take it out without spilling oil everywhere.

[@UPnDOWN]

So will I from now on!

[@VeryConfusedPerson]

On one of my favourite techical channels (AutoStrong-M) they dissected a 2.7 HDI and talked at lenght about the oil for the engine. To keep it short, they attribute the major crankshaft issues this engine is infamous for to wrong oil being used. Specifically, the oil should be B3 or C3, 5W40 or even 10W40! Jaguar and Land Rover recommend 5W30 B5 oil, which destroys the crankshaft.

[@UPnDOWN]

Interesting.

[@anthonyxuereb792]

I was in an auto parts store getting oil for my car and the salesperson told me that the new Alfa Romeo engines were made to such close tolerances that it is supercritical to give it the correct oil or suffer the consequences. Oils ain't oils goes the saying.

[@matthewblundell9119]

Took the sump off my wife's 206 1.6 HDi. Is about 300-400ml from memory (did measure it at the time) I modified the sump to push the plug down - from an "inny" to an "outy" to borrow belly button terminology as hated the thought of that last sludgy bit remaining at every change. I think - and is only a guess - that it's recessed so that if the sump is grounded out there's less chance of the plug being ripped out which of course would turn a bad day into a terrible one rather quickly!

I think the sticky out bit (which was handy to yank the old filter out with) has an O-ring. I think also said O-ring plugs a hole - hence, as the filter is withdrawn, the hole is uncovered and all oil in the filter housing is allowed to drain through the newly uncovered hole down into the sump. Or to put it another way, yes I think the book would have told you: loosen oil filter housing ahead of loosening sump plug. More specifically think it is loosen (but don't remove) the filter housing is draining all the time it takes you to get car raised and oil plug out. Then lower car, remove now completely empty housing and new filter as penultimate job (ahead of important splosh oil around the full perimeter of the filler cap position despite best efforts not to spill the stuff!)

[@andrewnaughton701]

Enjoying the updates. Same underdamped feeling in my C5 estate which has virtually the same suspension except for the variable damping system (AMVAR) that's on your C6. Good idea to test the spheres and I wonder if you can call Pleiades hydraulics as they are experts in Citroen hydraulics and possibly have developed a system for regassing grey saucer spheres with a fitted Tecnosir type valve. I also bought all new struts from Poland, cost quite a bit to get to Australia however you might not need them unless leaking, losing pressure after sitting, or worn rubbers like in my C5. I also have 5L of new LDS fluid. I think this might make the biggest difference to the damping because if the fluid has lost its viscosity then it would make sense for the fluid to flow through the damping valves with less restriction thus less damping. Lucky you have the program to depressurise the system, I have to work out which valve to open to do that manually. You could replace the fluid when you have the spheres off and see if that makes a difference. Also the AMVAR valves I read on the C6 forum can get sticky so I would be very interested if you got around to removing those and showing us how they work. You do look busy enough however!

[@UPnDOWN]

I can't see me removing the AMVAR valves, but you never know! I'll document it if I do.

[@556johny556]

I never owned a car with the grey spheres (Can't afford to get myself into a C6 and I don't care about C5s that much), but I thought one of the main differences between the green and grey spheres is that the grey ones are "sealed for life", meaning they don't have the hole in the top like the green spheres, which is also why the grey ones don't have the little nub on the top. So from my understanding they are not refillable like the green ones used to be. They meant to last longer, but unfortunately once they need servicing, the only option is to have them replaced. Or I could be totally wrong, I'm no mechanic. But I figured it'd be worth mentioning in case it is true so that you don't waste your time taking them all off just to find out they're not serviceable afterwards.

[@UPnDOWN]

Cheers. I know people who've had it done on a C6, though it may involve drilling the sphere - not totally sure.

[@mrc7478]

I like the air line blowing into the sump. Messy but loads more oil came out. My local garage likes to use an oil flush before dropping the oil. I'm never sure it's necessary. Would welcome thoughts on it...

[@UPnDOWN]

I don't like flushes really as there's the chance they'll block something up with some dislodged sludge. Regular changes using slightly cheaper oil are better, for my money.

[@imac3355]

Great vid as always, I have a few tips that might help you get a smooth ride out of your C6. My info is based on a C5 X7 (Fixed dampers) 18inch rims and on comfort mode. Be precise with tire pressure and always fill to the cars specs and factor in expansion when hot. 1-2 psi over makes a big difference. Definitely bleed out any air in the suspension system via front and back bleed nipples. I found air in the system makes the ride harder. You are right about the ride being disappointing after you reset to factory height. My 2009 C5 X7 wasn't right after setting back to factory height and it must be caused by pressure loss. I spent many hours driving and fine tuning the height manually to compensate for the slight pressure loss. I found the first 1klm from startup to be a little rough. After 1klm the car raises to its desired "middle" height setting on a normal road surface. This height is where you want the maximum comfort and do not overshoot as 3-5mm is a night and day difference. To high = dash and interior rattling and poor isolation from small road imperfections but good on big bumps at high speed. To low = falling into medium size potholes, bottoming out on big ones and residual bounce afterwards but great over small imperfections and interior stops rattling. I started off high and very slowly dropped it down tiny increments until I found the sweet spot at the cars "middle" ride height setting. This takes days over a variety of different road conditions but well worth it. My C5 now floats along and steps up to the higher ride height only when the road has big waves and not single wheel potholes unless huge. Hope that helps :)

[@michaeldavis7199]

I found woth my C5 that what brand of tyres used made a massive impact on ride- I fitted Michelin and car was transformed like night and day- yes they are more expensive but for ride comfort, road noise reduction and grip money well spent. I dont think the spheres will be a problem- mine were on their way out when I sold the car and were the next repair item- the ride became firmer not softer or wallowy so the theory in this video is wrong in my experience.

[@imac3355]

@@michaeldavis7199 Yes the Michelins are the only way to go. I think the best way is to test all 7 spheres for pressure loss refill or replace and manually fine tune the ride height for the cars middle height level. In my experience the height setting it's very very touchy especially running low profile tires.

[@tomaskusnir2374]

@@imac3355 Well in my case I bought goodyear tyres (I had bridgestones before that) and that made a huge difference for me. The old ones were runflat so that means firmer sidewall so no RF tyres for comfort. I think it also has to do with rubber compound, the softer the rubber the more comfortable ride it is.

[@imac3355]

​@@tomaskusnir2374 The tire type and compound make a big difference especially for lower profiles. I only use Michelins and inflate to 34psi all round cold. Once hot the pressure is around 35psi which is what the C5 requests.

The do not use a wrench instruction is for closing not opening. But actually I think it also says 25nm or something like that.

I dont remeber exactly how but the plunger in the oil filter housing is supposed to open and let the oil into the sump.

[@kd23se4]

Maybe it´s totally unrelated to your gearbox problem but...... I´ll tell the story anyway. We had a Peugeot 607 automatic as a company car. After repairs on the transmission (I think it was a ZF 4HP20) the car wouldn´t engage in 1st gear after coming to a stop. Letter it turned out to be that somebody who was working on the transmission with the transmission diagnostics left the W(inter) Mode enganged - and you couldn´t turn it on/off with the W/S switch. So......if you have the diagnostics (or know someone who has it) check it first.

[@turboneno]

I have to say, about floating like a boat, it is something that disappears when you drive a bit faster and without respect to suspension. Then it uses it's mass. It is simpy calibrated in hardware to faster driving than a CX wich is great in corners, if you are not afraid of the body roll, for example. XM is to "confused" over bumps in corners because he did not have double wishbone in front, like CX and C6 have. When you drive it like a boss, it is like a flying carpet. And really stable in corners.

[@UPnDOWN]

Wouldn't fully agree there, to be honest. I thought the XM was the best-all round ride I've had in a Citroen. The CX was smooth and soft - wonderfully so, but the body-roll DOES become an issue if it reaches the bump stops! As for the C6, I'm reserving my thoughts for the POV drive video :-)

[@alanbellwood3902]

Saab 93 Dispsticks are just a flipping vague on the Petrol Turbo unit. With oil a lot of service centres now only suck the oil out which means a lot of the ',good chunky stuff' stays in the sump.' Speaking to my oil supplier a lot of this thin oil is to do with MPG rather than actually the engine be at its best on it. Manufacturers also pushed by the fleet market to extend intervals which won't benefit the private man for longevity if he sticks to them.

also, as someone who hasn't driven a C5 or C6 ever, what you are saying at 30:20 about the lag seems fairly normal to me, maybe make someone else who has more experience in c6's do a test drive in it. Sadly a lot of more modern cars with Electronic throttles and autoamtic transmissions do this kind of shit, worst offender i had for that was a new vw arteon, 240hp 2.0L, you had to put your foot down at the start of a roundabut if you wanted to accelerate when you left the roundabout, my Mothers 2015 Laguna is also quite bad, takes like half a second when you put your foot to the floor until it starts to actually move.

You likely can't go wrong with oil filters from the main dealer, if they are still around. Might be a bit more expensive, but at least you don't need to worry about the quality or otherwise of an aftermarket brand.

Is there a discernable difference in the suspension in sport mode? Assuming the c6 has sport mode? The firmness regulator slide valve can get sticky, and, weirdly, corrode.. Although at that age the spheres are unlikely to be anywhere near perfect. If you've initialised the box and it's not improved the easiest way to see what's going on is get some live data from it, that'll confirm that valve block or something more sinister. As for hanging on to second, they do, bear in mind that on the v6's the autobox is on the edge of its design limits and the engine ecu limits torque output on request to avoid excess strain on the box.

[@UPnDOWN]

There's a noticeable difference, yeah. Sport mode definitely takes some float out. Spheres are bound to have lost a bit, and apparently even 3-4bar can make a big difference. How would I get live data, then? Do I need to come see you?!

[@docchevron1472]

A couple of bar is noticeable, I did the spheres on my mk1 c5, they were 2 to 2.5 bar down. The difference was incredible. Current c5 needs doing too. Switching your lexia to English would help! Parameter measurements is in there somewhere, forget where in diagbox, but it's there, then you can see in real time exactly what the box is doing against a set of expected figures. That said, IF it was the clutches slipping previously rather than the lock up clutch (it's quite common for the lock up clutch to slip) then it's probably the beginning of the end.. But again, live data will confirm it. Worth dumping the fluid again and seeing what colour it is, and more importantly, how it smells..

This is pretty much a Ford engine, though. They're built in Dagenham.

It's a real shame one cannot buy a nice comfy large Citroen estate. Modern enough for family duties.

[@UPnDOWN]

C5 is modern enough, to be fair. Xantia is in all ways too, except perhaps safety.

This 6 speed box is used in many psa products unless you come to a dead stop it never goes back into first gear. It's not a sporty gear box in any way it a leisurely turn of speed it does get caught when slowing and then flooring. It's not a fault

All makes sense, but I think this one is especially lazy.

[@chrispenn715]

Wasn't that engine jointly developed with/for Ford? Seem to remember Jaguar used it in the XJ and XF when they were under Ford ownership.........

[@UPnDOWN]

It was. It's more Ford than PSA, to be fair.

[@carstenweiland7896]

Changed all the Sphere and it was still floaty, the hydraulic pump went out, I got a new one and all was fine, I guess it is the pump not delivering enough pressure because a capacitor went weak!

[@UPnDOWN]

I think it's all working as it's meant to, to be honest. Just might have the gas pressures slightly out.

[@carstenweiland7896]

@@UPnDOWN Just told you my experience, got a new pump and all the annoying floaty mc floatface was gone. By the way it is possible to refurbish the system, the motor is a Renault part and the capacitors are changeable but they do need a bit more work. I think that a lack of hydraulic pressure acts the way as if you have spheres with too much pressure and then the damping is softer.

Ez valami elmeháborodott?

[@maartenc6099]

first of all I love your video series. I learned a lot about the C6. And for your information I do drive one daily. About the suspension I had mine calibrated by Johan Oldenhage. He has a garage and does a lot of servicing on the C6. kzbin.info/www/bejne/mJ7Qko1_ppqnnMU This is a video about how the calibrating works. Unfortunately it is in Dutch. This is not a very expensive procedure, costs about the same as aligning a car. But the suspension improved a lot on my car. He also flushed the gearbox and to be honest, It did not improve that much. The car shifts fine. But if I stand still at a red light and push the gas throttle , it does not immediately accelerate. It tense to wait just a little bit. I asked the garage about this and they said it is not abnormal behavior. You could chip tune the car, but honestly, I don't bother. If I accelerate it goes real quick. Love this car and do not regret buying one.

[@Strike86]

Is it just me or did the bouncing when the car stopped at 11:33 seem excessive? Could that be symptomatic of the pitching problem you're experiencing?

[@UPnDOWN]

No, it was on high suspension. That bouncing was a combination of the tyres deforming and the ramp moving, as there is zero suspension travel at its highest position.

[@Canalsman]

Just like the C6 now having had no awareness of it previously. It's a quirky Citroën, that's what attracts views ...

So If I were planning a bank job, perhaps a C6 with its sluggiish tranny should not be my first choice of getaway car even if it would do the job with style and comfort.

As I said though, it's temporary. It's coming out again in about 500 miles.

[@rupertthomson]

Is this the same engine used in the (older) Land Rover Discovery? The channel "Land Rover Time" did a video about the correct oil to use: kzbin.info/www/bejne/h2Wxln2ol9SlatU Turns out 30 might be a fudge for emissions or something. Their investigation came after rebuilding an engine with a snapped crank shaft. Cheers!

It's the 2.7 TDV6 in the Disco. Thanks for the heads up, will check it out.

Citroens are over there, you just have to look. Granted, nothing as recent as a C6. Could you not import?

Mahle oil filter…….

[@UPnDOWN]

Correct.

[@adidragan]

"Lasts for the life of -whatever-" is the biggest pile of bollocks car companies peddle. Like timing chains that last for the life of the engine... Well of course it lasts for the life of the engine, because when they fail, you need a new engine (or at least a rebuild).

[@UPnDOWN]

Tru dat

[@fulminatorc6]

I would like to ask Citroen to clarify what they mean by the "Life of the vehicle", because the shitty advice they give certainly shows they only care about it until the car is in warranty. I mean Citroen says the gearbox is "sealed for life", no maintenance needed, or make engine oil change at 30.000 km... That´s horrible advice! Oh and now the coolant pipes are being discontinued. The last C6 was built in 2012, so that´s it, they don´t supply the damn hoses :( So if we consider all this, the "Life of the vehicle" in eyes of Citroen is no more than 10 years!

[@UPnDOWN]

Exactly. Car manufacturers are after profit, not longevity. It's in their interests that their cars last long enough to market them as reliable and dependable, but not so long that people won't want to buy new ones. The C6 is now of the age where Citroen don't give two shits about it, yet the fans of the marque's greatest hits still do, and will likely continue to do so. The question is can they all be kept going as easily as the older stuff? It's comparible to the Vulcan being grounded while the Lancaster's still allowed to fly.
