[2006] Peugeot 407 SW 6-Speed Auto Slipping Out of Gear?

[BadIdea]

Probably nothing to do with it but with the codes being related to the dpf and the kangarooing, was the engine nice and hot but not going fast. Also when you got out did it smell hot? Has it ever kangarooed with a cold engine?

I didn't check the temp at the time, but I was only about 5 mins into the journey I'd say so the engine was probably fairly cold. This could be purely coincidental, but it seemed to start after driving up a cobbled street. It really did feel like the gears were popping in and out, and I wonder if that was really happening but as a result of the power stuttering.

You really need to make 100% sure it is a full chip revision C kit - beware a lot of the cheaper ones are not and this will give you communications problems with a lot of full CAN vehicles.

Although we are not affiliated, members of the FCF can get a 15% on diagnostics equipment from a popular supplier to members:

Thanks. I checked their website and unfortunately it appears that the Lexia kit is out of stock at the moment. I found this on Amazon though which claims to be a Rev C device:

https://www.amazon.co.uk/Lexia-CHIP-REV ... 613&sr=8-5

That one looks kosher.

Thanks, I've ordered it. Looking forward to trying it out this weekend! I'll get a 32-bit VM configured and ready.

Just be prepared for a long night, grief, lots of pain - as in pulling 2 teeth out without anaesthetic and palpitations.

These installs can be horrendous. Be aware that there may well be additional issues with a VM install - specifically comms issues with the required USB drivers needed for the VCI, firewall blocks and such.

In the end I borrowed a really old laptop with a dead battery from a friend. It took several hours to install, but it did seem to work! I gave up trying to retrieve the faults log as it was still processing half an hour later, but I did manage to pull some faults from the report tab (I've left out the data with no faults present):

Could you help me decipher this please?

[moizeau]

Looks there is a regen problem, amongst other things.
Have a read through this and see if it's similar
viewtopic.php?t=60390
Sorry it's a long thread.
Now that you've got the fault codes that are logged you need to clear the faults and re run the global test. Some of the faults could be very old and weren't cleared. Once you re run the test look at the codes that are current.
I notice the log said 'moderate town driving', does it ever go on a blat down the motorway?

Thanks, I'll have a read. I did wonder about clearing the faults, but would that matter for the ones that are marked as "permanent"?

Regarding the type of usage it gets, it really only gets used a couple of times a week at the most and then it's mainly 'B' roads and sometimes 'A' roads. I do take it on 1 hour+ motorway trips every now and then but haven't noticed the regen kicking in (does it indicate anything on the dash?)

[moizeau]

No, it doesn't tell you but can see in Diagbox when the last regen took place. You need to clear the faults then re check to get rid of 'old' ones that will lead you up the garden path. Use Diagbox if possible, not PP.

Yeah, I'm using Diagbox 7.83. I'll try clearing the codes and see what turns up again. Probably a good idea for me to check the DPF stats then, where do find them in Diagbox? It does say "regeneration problem" in the fault report.

[BadIdea]

Okay, this morning I cleared the codes and took the car out 25 miles and then back 25 miles a few hours later. A good portion was motorway driving. I read the codes again once I was back and got seven engine management faults:

Is it looking like the DPF needs replacing?

[moizeau]

Not necessarily, it also says that the additive is low (this is 'guessed' not physically measured) and the fuel flap sensor (which tells the car when you've put fuel in) isn't working. Have you looked at when the last regen occurred? I think this is in 'injector ECU' but may be wrong. regarding the first 2 someone with more knowledge will need to chip in as I've never had issues with these. While you've got Diag plugged in it would be worth doing the actuator tests on the air inlet butterflies.

[BadIdea]

I took the car to a Peugeot indie last week who found it strange that the engine management light wouldn't be on based on the list of faults, but then found that a function had been deleted to mask the problem (great - I'm assuming this was the garage I bought it from).

Anyway, they changed the fuel filter (apparently it was pretty bad - I guess the most recent service from the aforementioned garage wasn't very thorough), added 2L of additive and reset the DPF status. So far so good, although time will tell as the problem was very intermittent. They also said that the fuse box was corroded and could be causing some of the electrical gremlins. They've said that if I can source one - part no. 6500CG - then they'll fit it free of charge. The problem is that Peugeot no longer do it (same with the additive as it happens - I guess shelf life isn't a priority!), so I'll have to find one secondhand I guess.

Part 6500CG is very much available from Peugeot. I've just checked parts live and is not showing as NFP. It is £273.71 inc, VAT new.

Thanks, I wonder if I was mixing up what he told me. Yikes at the price though!

[GiveMeABreak]

Yes, but bear in mind you are paying for a brand new one - a second hand one may have faults / failed relays or other issues. I can also tell you that there was a problem with some of these fuseboxes that required replacement - I can't remember now, but a failure of one of the internal switches led to several fault codes being displayed and the official resolution was a fusebox replacement on the 407.

Okay, I think I'm just going to pull the trigger on this one based on recent problems with the car.

Is this part OEM?
