407 very intermittent surging

[moizeau]

Cheers, I'm in France so possibly better luck with the parts. No GM garages round here (or SAAB)
I'll let you know how it goes.

Let's hope ....

Parts 5 and 6 from this diagram

[moizeau]

Got the bits ordered, 2 of each. Bank holiday here tomorrow so will arrive Friday. Something for the weekend I feel.

Great, good luck with the oil change.

It will be interesting to see if it solves your little issue.

Remember to take plenty of pics for the forum as the more info we gather the easier it will be for other members who wish to change their own AM6 oil.

Got the parts this afternoon so decided to attack. First job , remove the undertray, then find the level / drain plug. Then remove the crossmember to gain access. Then remove the air filter housing. That took a bit longer the first time than it should (as with all 'new' cars). Right then, how do I get it off the ground sufficiently to undo the drain plug? As with all newer cars the splitter sits too low to get conventional ramps under, then I've got to raise the rear as well? I first inspected the underneath by lifting the car on one corner using a ramp on full lock. Doesn't work for a gear oil change. Then I found that I need a 17mm allen key (should have researched), who has one of those? Put it all back together to go and get one. Still the problem of lifting it?
Went to see a mate with a cow shed that has a concrete floor with an angled drop off of 20 degs. Tomorrow with 2 concrete blocks, 2 lumps of wood, I should be able to get the job done. I will take photos, it should be hopefully successful and entertaining to the onlooker. (hopefully not to 'entertaining' for me!)

Often a problem getting cars with any kind of low front spoiler/air-dam up on to ramps. Helps if you have a liquid Citroen of course, but otherwise can be a pain to get the car lifted high enough to work underneath.

Some fairly scary devices pictured on the web: try googling 'screw-jack car ramps' > images . . . many of which look really poorly braced, or seem to rely simply on single hydraulics holding them up, sometimes at 1m+ in the air. Even some cheaper commercial 2-pillar lifts have killed and injured users, according to HSE reports.

Did see this on the web, though, amongst some of the DIY ramp offerings. I thought it looked strong and sturdy, unlikely to give way, and eminently simple to make, if you have some reasonably decent welding skills:

What I did like was the gradual ramp angle, and the ability of the ramp to be simply detached from the front-end sturdy stand, so freeing up access under the sills.

I know Michel has some 'ramp extenders' that can hook over the 'climb' of a normal fixed ramp, improving the angle and extending it. Those extenders meant that ramps that would not initially fit under the front spoiler now do. This is what I mean (although, in the image, they are the wrong way up; they are meant to hook on a cross strut.

My finger was hovering on the "BIN" button until I remembered that my ramps 'disappeared' some years ago.

Wish I could remember who disappeared them

[moizeau]

Yes Chris, Love the Bx for being able to be high, place 4 ramps under all wheels...nice. Same as the Landy.
I use ramp extenders for one axle (bit 8x2) but for all 4 wheels?
See how we go tomorrow with the the improvised cow ramp?

[Hell Razor5543]

I have seen a set of home made ramps where somebody got hold of a railway sleeper. Measuring a foot back from the end they then cut them diagonally to the same point on the other end and side, fitted some guides and end stops, and voila! solid ramps. They do need a bit of effort to move them though!

[EDC5]

When I did my AM6 oil change I jacked up each corner in turn and placed a few concrete flagstones under each wheel to get it spot on level.

Since then though I've just used the car lift and not bothered too much about being perfectly level as there is a range of acceptable oil levels as evidenced by the 10 degree window available for setting the correct level.



I did a little write up here: viewtopic.php?f=3&t=58134&start=45#p543115

Just remeber that you need to have the engine runninng whilst checking the oil level.

[moizeau]

I've read your post several times, very useful. On the ramps issue, I think that's called 'showing off'.
Here's a picture of a modest version.
You say the filler plug was a bit tight, I think that may have been an understatement.
Special tool based around a 3/8 socket with tape to stop it arcing the positive battery terminal. and an extended handle.
Here are some pictures of the 1st, 2nd and level drains. I noted the counter : 2536646
I wonder how this compares to other counters?
I went to reset the counter but, I presume, due to Mr Pug not specifying oil changes there isn't a reset option, only a write to ecu. It says it's for when an ECU has been replaced so it can understand the current oil usage. I haven't tried it yet but I'm guessing that I just type '0'?
The oil isn't great still so I'll leave it a month and then due another change. From what I've now got in the bottles I think it was about 0.5l short before. All went very well apart that I've now got a depollution error! I hope it's because the engine was run with the 'air sensor?' disconnected?
When I do the cam belt in about 10000m I think the crank seal needs doing aswell. A bit oily on that RHS.

Sorry that the pictures don't match up with the words, but I couldn't work that out, so just dragged and dropped.

[EDC5]

Great that you got it sorted

Yes, I assume if you ran it without the MAF sensor then it will cause a fault. I think, once reconnected, the fault will disappear after a few journeys.

I'm not sure about yours but there was definitely an option to reset the oil wear counter, I think it was under 'pack repair' rather than the 'repair' option. If you've written it as 0 then I'm sure it achieves the same thing.

Did those planks of wood support the weight of the car then? I'm very shocked

[moizeau]

I believe Citroens have a reset option but peugeots don't as it's deemed as sealed for life and doesn't show in any service schedules. The planks don't do them self justice on the photo, they're 8'' x 3'' and I only ventured 2ft onto them. They look small because of the tyres which are off an agricultural trailer and are an equivalent diametre to a LWB landrover only twice as wide.
Cheers for your guidence, lets see what happens next?

No difference between Citroen and Peugeot Pete - your 407 needs the oil counter resetting or the AM6 adaptives will all be to hoot.

Procedure for Diagbox, but will be similar if it Launches PP2000 as your vehicle is 2006.

• Select the Repair Menu in Diagbox
• It may run a Global Test - if it does, let it finish
• You need to select the gearbox (AM6B for your 407)
• Then Pack Repair
• Replacement Parts
• Replacement of Gearbox Oil
• Then you should be able to reset the counter to 0.
