    Default New owner of `06 C5 2.0 16v Sport Automatic

    Hi
    Last weekend we picked up a 2006 C5 2.0 16v Sports Auto in Sahara Gold with 74,500 Km.

    It replaced a 2007 Renault Megane Sedan that was written off on 30 October - that`s another story all together.!!

    The C5 is a great looking and driving car, very different to what I am used to as the Megane was a manual.
    This post is at the request of my wife as she drives it most days for the school run and work.

    With the 4 speed adaptive auto - it seems to hold 2nd up to about 3,500 -3800 rpm before shifting.
    Is this normal? Or is she driving it `miss daisy` style and needs to be a little more confident in acceleration?

    I drove it Friday arvo and it seemed fine , I put it into `manual` mode and found that the shift from 2nd to 3rd was not forthcoming on the gearstick , then it changed by itself to 3rd and 4th.
    Are there any tips on the use of this transmission? Sounds a bit naive I know, but the only other Auto I have to compare it to is our 2011 Megane with a 6 speed auto .

    I had it back to the dealer on Thursday as there was a fluid leak, which turned out to be a circlip on a transmission seal not on correctly from the previous owners service of the transmisson by a Euro car service centre in Brisbane. This was rectified by the dealers mechanic - no questions asked and the workshop went out of there way to explain it to me as it only started to drip out when the car got to 60km/h.
    No more leaks & the car is really nice to drive.

    Cheers

    Be decisive with the auto. Press hard to accelerate, push the brake hard (initially) to slow. "Feathering" will lead to the least decisive events. 1-2 always bangs a bit - depends on wear and trans version, it also revs much higher when the oil is cold. While a 3-2 kickdown "whump!" is quite common, I think it's a valvebody issue not a software problem.

    It's not that uncommon to hang on to 3rd at about 60km and then change up once you get to around 70.
    The shifts can be a bit erratic at times and that's fairly normal for the gearbox in question.
    I expect it will have a switch to put the gearbox in 'sport' mode, which basically makes it hold gears until higher engine rpm. Have a look a the handbook and see if this has any bearing on the behaviour.

    Thanks for the replies guys.

    I took the long way to a destination yesterday to get a handle on the shifting of gears.

    As mentioned there is a sport switch which does hold the gears longer, the changes are pretty smooth , no `whumps` into gears.
    I have read the books that came with the car a few times, doesn`t really tell me a lot, there is a Australian C5 Restyle pamphlet that really has no useful info at all in it!!

    As mentioned above the changes are a little erratic, sometimes changes earlier to 3rd, other times as mentioned above , it will have to be over 60k to shift.

    Also mentioned in a response above , as oil temp gets up everything becomes a little nicer overall.

    Thanks again , and it`s good to know this forum is about , from what I have read so far , alot of knowledge in here on the French vehicles.
    Cheers

    Even on the C3 - it will be hard to get the car in to 4th - from memory it only does it in excess of 80km/h, but I'm assuming that the shift points are different in the C5. Flick it in to tiptronic and select the gear manually.

    Within reason you should be able to select any gear at almost any speed in manual change, [to prove that part of the system is working ok]. Changes in auto or manual should be smooth, without any bangs or thumps regardless of speed/load situation, This is a controlled slip transmission so any slight incline or load when excellerating will produce a slipping, quite noticeable in 2nd, if insufficient throttle is used. The converter lock up happens automaticly in both modes, sometimes giving the impression of an unrequested gear shift. If nothing else, your description seems to indicate a possible suspect output speed sensor. This little item gives all sorts of strange gear changes, erratic converter lock ups, or lack of when faulty, and is often overlooked. It's cheap and easy to replace. Cheers.

    Thanks again for the replies.

    After a couple of weeks of driving the car - which is great , there seems to be a few moments of wierdness - just trying to get a handle on the characteristics of the vehicle before I speak to the dealer about it for warranty purposes (it has a 3 yr warranty)

    Tee `tiptronic or manual mode` also holds second for quite a bit , will not change on use of gearstiick, then when reaches about 4000 rpm it will change to 3rd then 4th as I have pushed the stick to try and get it to change twice . Down shifts are spot on,.
    But going up 1-2 fine can shift anytime, 2-3 temperamental , 3-4 whenever it is requested.

    Also have noticed some dead spots on accelerating when turning a corner, no power on initial press of accelerator, but picks up when you lift off and press again - maybe has happened about 4-5 times in about a month of daily driving.
    The Mrs had it snuff on her when at a light and had a green arrow as she went to take off , it stalled, put in park restarted and went fine, but no error lights/faults lit up.

    Also finding that when coming up to light slow , before you apply full brakes to stop , it vibrates but decreases a great deal when full brakes applied. I also found that idling through a car park with A/C on it tends sound a little rough, and drops in power like it is going to stall.
    I know an engine mount was replaced before it was sold. And new front discs and rotors replaced.

    I am assuming that these are not normal workings of this transmission or accelerator

    Any help on this weirdness would be greatly appreciated.
    Cheers

    Have it re-programmed. This normally fixes this. It could be the coil pack otherwise. A common issue with most French cars of that era.

    The car is with Citroen/pug specialist - reprogram did not fix issue . Valve body being looked at . Nothing has been diagnosed yet - if it's a valve body repair - what am I up for ? Warranty should cover first $1200 if I am lucky.

    The cost depends on what's done. Changing one or both electrovalves (for pressure modulation and converter lockup) that are often changes should be under $1k. Replacing the valve block alone is not the usual repair, but that would exceed $1,200 if it requires replacement. A gearbox replacement is probably about $5K, should it be necessary. Just be aware that the petrol 4 cylinder C5's can be a bit slow off the mark and there can be a slight lag when moving off from rest. If you push the accelerator pedal harder, you may find that it surges after the lag, which can be a bit of a surprise.

    I've got a really laggy one floating about at present but it's slightly earlier (2001, cable throttle). Have been slightly suspicious of the TPS, all mechanical items/high tension being good.

    Thanks for the replies .
    Hopefully some sort of answer will be available today.
    I hope its just the valves the need replacing, not bothered if I have to pay more to have a transmission that`s in tip top condition once repaired - not too keen on a full replacement!! That would be 50% of what I paid for the whole car.!

    Found out this arvo - transmission full of red fluid - not correct.( which I worked out only after reading a bit here on this forum)
    A flush and refill is on the cards - then from there hopefully all fixed.
    At least I have a place that I know is an expert on these cars and will be taking it to them in the future.
    Thanks again for all the help here.
    Glad I found the forum!

    reprogram, Flush & refill didn`t fix problem , seems worse especially after abour 35 mins driving and holds first until about 5000rpm , but the 2 -3 is ok at that point.
    It is weird, the first 20-30 mins of driving - 1-2 is ok - 2-3 holds until 4000 -4500, then it seems when everything is pretty warm it gets worse on 1-2 shift, and manual shift is actually non responsive/sporadic/inconsistent after oil temp comes up.

    Line pressure issues, at a quick guess. If it was shunted onto a hoist with the engine warm you could tap in a gauge to read what it's actually doing. The pressure sensor may be fibbing. I'm assuming you did change the electrovalves.

    No the valves weren`t changed as the Auto place was closing down for 2 weeks.
    I am going to get them changed in the New Year, hopefully that will be the issue.
    I will go from there.
    thanks again.

    Found a place in Nirthgate Brisbane that specialises in Citroen & Peugeot .
    Took the car there Thursday - found out today - full trans rebuild required , basically no fluid lubricating 2-3 changer , a fouled oil cooler . Will find out soon if warranty will pay covered amount if $2500 and I will pay the rest .
    Having 80k service and timing belt done while car is there .
    Oh well things happen - cant complain - first big issue with a euro car in16 yrs of euro cars .
    The mrs is not seeing it the way I am . C'est La Vie .

    Nasty shock. You might care to read up on the improved parts Sonnax offer for the AL4, and enquire whether you're receiving them.

    Thanks
    Made the query to the mechanic and the Sonnax parts are being used .
    Hopefully only another week and I can get the car back?
    The public holiday will slow it all down though.

    Picked up car on Tuesday - drives like a dream!
    And warranty company paid half the bill for rebuild ($5k total)- so pretty happy

    If anyone wants to know of a great French/euro car mechanic in Brisbane northside , contact me email or PM and I will give you details.
    Considering 2 other so called Euro car experts looked at and were at a loss, One even used the wrong trans fluid in the `box` .
    This guy went out of his way to find and fix the problem correctly and dealt with my warranty company and had it all sorted - took a little over 2 weeks , but the car is completely different to drive compared to prior the fix.

    There are little pockets of gold in every city. Hard to find though. Great outcome...

    I think there's too much belief that these devices are strange and unique. When you go and ask around, there are horror stories for most brands. The key is finding someone intelligent and competent, not to mention honest.

    I'm very pleased the gearbox is sorted. Really miss mine; lift off on the 4HP18 and it's nowhere near so cluey about changing down for you.

    Spot on , this guy was honest from the start, made no qualms about the fact there were problems with these gearboxes.
    I saw the bits that came out of it, I was surprised it even still functioned in any form.

    ... indeed, because it's entirely hydraulic, whereas the 4HP20 and AL4 are electronic with smart software and more sensors to do what the governor is supposed to do in the 4HP14/18.

    I know some people who have just spent almost as much on their hound, but it's good to hear it's been properly repaired and the insurance tipped in.
