My Peugeot 407 SW`s engine management light comes on often. It`s nearly always in the same area of the UK, ie same spot. The car may or may not go into limp mode. It has been on a number of scanners, main dealer and other. Though I am told they clear random entries, nothing is replaced. It normally resets itself within a short time, but if it does not, I can park it in a particular place, switch the engine off and on, it will always then reset and the light goes out. What could be causing this please? (Estate)

My Peugeot 407 SW`s outside air temperature is reading 10 degrees too low and this affects the accuracy of the aircon. If I hold my finger firmly on the wing mirror sensor the reading alters from my body heat. Is there a reset procedure that I can do myself? This reading and the time reading are flashing all of the time and will not reset. I would appreciate an answer as I find it rather frustrating. Thank you.

My Peugeot 407 SWs warning display shows ABS and ESP but the car drives as normal, even under heavy braking. Should I notice a difference or maybe could it be a computer glitch?
I have had this problem quite a few times. Usually, there is nothing wrong with the ABS / ESP system except for a faulty sensor on one of the wheels. Once the sensor is replaced, the warning lights go out. My recent problem cost around £100 including the sensor. The garage connected their computer, identified which sensor had failed and replaced it for me. - Ray Mitchell from England
Try changing the break light switch under the passanger side footwell. A very quick (cheap) fix and it sorted out my car. - Stefan Trzoska from Leicestershire

My Peugeot 407 SW has a water in diesel alarm appearing fairly often now, usually on second start from cold, not the first start. I have had the fuel filter replaced but this alarm still shows. On some trips the engine appears to stagger for a second or so then runs normally. On the last occasion the engine actually cut out at about 40mph and the auto box faulty alarm came on! I switched off, switched on and restarted and the car ran fine. I only use premium fuel (not supermarket) and the problem never occurs when the engine is warm. I have had this car nearly six and a half years now with very few problems and it`s a cracker. It`s done 58k now so not much work and I would appreciate any help to solve this dilemma? Many thanks.

I have a Peugeot 407 SW diesel which in between gears sometimes will rev high then clunk into the next gear. My dealer said it’s either the gearbox or hydraulic block but could not say which. It seems some other people have had this problem. Can anyone suggest which is more likely, as the hydraulic block is cheaper than the gearbox and I`’d rather go down that route first? Thanks for any replies. (diesel)

I recently bought a Peugeot 407 SW with only 32k on the clock. It has been back to the dealer twice already for the following problems. I will be driving along and without warning the depollution light pops up, followed by ESP faulty and then the engine cuts out. This has happened in town, in the country and there is no real pattern to it. It’s been plugged into a laptop and there are no fault codes in the ECU. Has anyone else experienced this out there?
I have a diesel 407 sw that did the same thing and it was the diesel particulate filter that would not regenerate as it was badly clogged from town driving.I had to eventually have the dpf changed, although my 2008 car has done 94,000. Try a long run at high revs to see if the dpf will clear or put in your fuel diesel particulate filter cleaner that makes the dpf regenerate at a lower temperature. It maybe also the dpf fluid has all gone out the tank underneath the car in front of the driver’s side rear wheel underside of the car. Hope this helps. - Simon Oakley from Staffordshire

The back window on my 07 Peugeot 407 SW station wagon keeps popping open for no reason. I have to keep shutting the window every time the car is opened! Could it be disconnected?
Had same problem. I found with the back window open was to turn the wiper the opposite way leave it there and close. Problem solved. When you turn wipers on it clicks back into its proper position. Don’t know why it works. but it seemed to solve it. Hope this helps. - Adi Smith from England

I have a Peugeot 407 SW. How do you reset the ecu unit after filling particulate filter with fluid? The computer still shows fluid is low. (estate diesel)
I have the same issue and I was told by a few mechanic friends, as a cabdriver I know a few, that only the dealer can reset it because of the software. It will cost about £50 pounds for a 5 min job. I was advised to leave it till when next service or MoT is due as some garages might have the software and do it during the mot/full service process without charging any extras, as they have to hand it over with all fault codes cleared. - Petros from England

Why does my Peugeot 407 SW 6 have no glow plug switch on my dashboard light configuration when I turn the ignition on? I thought all diesels had this light to let you know that when the light went out you could start the car?
Because on these newer models there is no need for it. In theory you can drive it straight away cold, personally I still run the engine for a couple of minutes before driving off especially when it drops below 10C. - Petros from England
Some 407 engines do not have glow plugs so do not have dashbord lights. Maybe yours is the latter - will i am shores from Yorkshire

I have an intermittent issue with the remote unlocking not working on my Peugeot 407 SW. Most of the time it`s fine, but usually when I am in a rush the car does not respond to either of the keys. The previous owners have obviously never used the key in the door as the barrel is ceased so I can`t get in. I have seen several posts on forums about resetting the system by playing with the lights when the battery has been reconnected etc, but this appears to be a short term fix. Can anyone help me with either a way to fix this, or disable the automatic locking when the car is left alone as it is secure overnight anyway? Cheers. (SE)

Hi. I filled my Peugeot 407 SW`s power steering with the wrong oil and drove two hundred miles with no problems. I started the car this morning and there`s no steering with the display panel saying power steering fault. After draining the pump and rack and replacing with the correct oil it`s still reading the same on the panel? What do I need to do? (estate)
If it drives fine now and the actual steering is working as it should than is just a case of clearing the fault code. Anyone with a diagnostic would do it in minutes for a tenner. If the steering is malfunctioning it’s a garage job; some clear the fault codes by unplugging the battery for an hour or so, but I wouldn’t recommend it. - Petros from England

I have a Peugeot 407 SW and the braking bulb keeps coming up as a fault, the right hand turning signal keeps flashing up and some other fault keeps flashing to do with bulbs. I have checked and all lights are in perfect working order. The beeping is driving me up the wall. My mechanic tried to clear the codes and a few miles down the road the warning kept flashing up so I am at a loss. Can anyone help please?
I had the same problem few years ago, however at that time managed to find on the web the step-by step description how to solve, and it was a complete success. Having it done by the dealer is very expensive (£250 at least), however the DIY job that I did was a 100% safe and it was only few pounds. Actually the problem is caused by a short circuit from the car wiring harness (earth) to the rear light cluster. The wire that Peugeot used is very thin and possibly not up to the job. The earth pin on the plug seems to burn up causing a continuity problem to the cluster causing the car to have an intermittent connection to the cluster. This throws the faults as the car self diagnostics thinks the bulbs are blown. I have a complete PDF file with the description, however this site does not allow the attachment. Actually what you need to do is to remove the side panel inside the car boot by turning the plastic screws to the vertical position and pull the cover away. You will now see the light cluster, wiring harness with plug (into the light) and if you look down between the rear storage basket and rear panel, you will see the current earth wire attached to the back panel of the car (factory earth point). I kept my original earth point connected onto this point and just added a new Earth wire between the original wire and the car chassis. It worked. - Barney from Surrey
I had the same problem plus with the added bonus of the esp/asr warning too. I replaced the brake light switch and have had no problems since. - James Blackmore from England

Hi. I`m looking to purchase a Peugeot 407 2.0 SW diesel Estate year 2006 with 134K miles on the clock but it all Peugeot dealer services and has had the fly wheel and clutch replaced last year at 114,000 miles. However the MOT shows a couple of advisories. One is the power steering warning light indicating possible failure. Two is the nearside front suspension has slight play in a lower suspension ball joint. Three is the nearside rear brake shows signs of overheating. Is this something I should be worried about before purchasing from a garage? The asking price is £2765, the bodywork is in great condition and everything else seems okay. Thanks.

I bought a 2005 Peugeot 407 SW 2.2 petrol in 2010, 100k. Last year it started overheating so I took it for a check up and I was told that it has blown the head. I used it for 3 days and then left it for a week. When I came back I started it and took it for a ride and after 1 km drive it started with the same problem, "STOP" too much pressure on the engine. The gauge went over 90’C straight to Red. When I opened the bonnet I found that the reservoir was empty. I opened it to re-fill, air with pressure came out and water came up but it was only a quarter empty. Other days the gauge moves up and down between 80’C and 95’C, it doesn`t stay in one place. I like the vehicle. Can anybody help me with this problem please?

My Peugeot 407 SW will start normally and run okay, but when I later stop and turn off the engine it only makes a loud click noise and won`t start again. This seems to happen only when the engine is warmed up at normal operating temperature. It will restart again but only after many attempts at turning the key for it to catch. All the fuses are okay and no warning messages have appeared on the car display. Does anyone have any idea as to why it is doing this please? (Automatic)
Loose earth wire on the Engine, as the engine gets hot it expands so looses good earth connection, so tighten the earth to the engine and that should sort your problem. - Grant Webb from Kent

Hi. My Peugeot 407 SW is "jumping", after the oil temperature gauge shows 115 Celsius (actually that’s the max temp where it stops as well). There are no display signs of any kind, faulty announcements on the dashboard, or records of any faults on the computer at the garage. On a regular basis, the car revs, lags behind and then catches up (while driving) in a quite severe and very concerning way. Also, when it’s warmed up (oil at 115 degrees Celsius) in a stationary position, it "clangs" in between "drive" and "rear", shocking the vehicle when it switches. It`s been to a few garages (Peugeot included) and they have no clue. They`ve checked and changed the tranny oil with no effect (it was very clean anyway and the manufacturer claims to be maintenance free). They didn’t change the oil filter/s (is it one or two!?) though, as they didn’t know how! Some say it`s the hydraulic block, some say it`s not, as sometimes (on rare occasions) the car doesn’t jump! The two fans (in perfect working condition) don’t kick in as that would help the cooling. Incidentally I`ve just discovered that the cooling system works intermittently as well, so that doesn’t help. BI bought this car in November 2012 as a third owner. The car is in an overall excellent condition but this defect drives me nuts. Any suggestions would be highly appreciated(including a good garage in Hungary, former Yugoslavia or Austria). I actually live in Canada, but I’m stranded for a while here in Romania. Can anybody help please?Thank you. (automatic 2.7L 204 HP)
Hi, firstly, let me say that I’m no expert on car mechanics but I do own a 407 and have a similar problem with the auto transmission. After reading many blogs online I’m sure the problem is the hydraulic control block on the autobox which controls the twin clutch and gear changes. This is one of many common faults on the 407. Apparently a Peugeot main dealer will charge upwards of 1500GBP for the repir, whilst an independant automatic transmission specialist will charge about 750GBP. I am about to get mine done. I also had cooling problems caused by the fan not working. Peugeot estimated a cost of about 600GBP; but I found a fan on eBay from a Citroen C5 which is identical, for 78GBP and fitted it myself (about an hour’s work). Hope this helps! Paul Edwards from Carmarthenshire
Hi, thanks for your answer. Eventually it turned out that the hydraulic block, the converter and the transmission , were all concuring to the problem, so I had a major rehaul and change the three of them, and yeah, it set me back a few quids ...:) Anyway, for the record, had somebody told me to change just the converter in the first place (and just maybe) the hydraulic block, the transmission had still be OK, to this day. But, as that didn’t happened, aproximatelly 80% of the transmission got brand new parts. BTW, found the famous AW1 TF as well, at ... a Saab dealer, just under a different name. Happy end, car drives like a dream car now...:) John St. from Romania

Hi there, I have a 2005 Peugeot 407 SW. I have problems with my indicators, they are sometimes working and sometimes not, it`s only at the back though. Also my brakelights aren`t working and my third brakelight, the Led at the top af the glass bootlid is always on. My Peugeot dealer said it`s my boot fuse box that needs replacing and my brake light switch. It cost me about £72 just for them to look for the problem. I just want to know is the boot fusebox on the 407 Sedan the same as on the 407 SW? I might get it from a guy that is stripping his car for parts. I`d also like to know where is the brake light switch located and what does it look like? (2.2 litre sport petrol)
I’m pretty sure the parts are the same if you check ebay and find a business seller that has one they usually tell you which cars it will fit you can also phone car parts supplyers like Unipart give them your registration and they’ll tell you the part you need and probably a code - Lynnette Newman from England
If its a case of the display saying a bulb is blown, when all are good or when you press the brake pedal you sometimes get brake-light failure warnings or indicator failures at the time. Its a well known fault and very easy to fix. It is actually a earthing fault in the one of the rear light clusters or both. there is a Mod out there. http://www.scribd.com/doc/97546219/Peugeot-407-Rear-Bulbs-problem-fix hope this helps worked for me, good luck - William Robertson from Lothians
Hi, if you don’t want to go to the trouble of carrying out the mod, a liberal squirt of WD40 does the trick too. It certainly worked on mine - no further problems with the rear lights for over 6 months now! Paul Edwards from Carmarthenshire
