    Default Peugeot 405 GR 1988

    Hi this is my first post here as i just found this site today and have been reading over it.

    Anyway about 6 months ago i purchased a Peugeot 405 GR 1988 for 900 dollars NZ.

    For 900 dollars i knew there would be some problems. First off i had to get the Shock absorbers replaced to pass Warrent.

    The next problem i had and i am not sure if this is common in 405's was that the breaks after being applied and then released they did not fully release and were pretty much always on. So the car was slower and the breaks were wearing down faster etc. This was a hard problem to fix but was not expensive it ended up being a worn cable of some sort that needed to be replaced.

    That is the only work the car has had since i got it (and an oil change).

    Heres the problems i still have and want to try do abit of DIY on some of them since they do not seem like big issues.

    Problem 1: This could be a big problem and only started about 6 weeks ago. While driving around especially in 3rd gear around 2000rpm's when i release the throttle the car kind of jolts a little and there is a noise under the front passenger seat kind of like a Thud. It happens 90% of the time while driving when i release the throttle. Also does it when i tap the breaks or just when i break in general sometimes. Someone told me that it could be the Diff? Any feedback on this would be great.

    Problem 2: When i put my foot flat down on the throttle the car is so sluggish and jolts mainly in first and 2nd gear. Also when taking corners if i give it abit of accel around the corner the car just goes sluggish and it seems like the car gets fuel then doesent because it will jolt (Not a fun driving experience at all). I do drive around on an empty tank most the time running on 5 dollars gas etc just because im at school and have little money for gas. I thought this could be why but it still does it when i do put heaps of fuel in the car so i am not sure what could be the problem.

    Problem 3: Is it just me or is the Electronics in this car wired with 1950's technology? The power window switch on my side for the passengers window does not work but has worked on odd occasions (very strange) and sometimes the front passengers switch will not work when the passenger trys to use it but does work 90% of the time. Just the other day the light for the clock stopped working which normally turned on when i turned the car lights on. Any ides how to fix these problems?

    Problem 4: The heater has no life at all and was not working when i bought the car adjusting the controls does nothing.

    Problem 5: The speedo jumps a lot of the time say im driving around at 40km it will flicker from like 37 to 43. I read somewhere on here that you need to replace the cable. But what Cable? Would i need to pullout the dash and stuff and replace the cable that goes from the speedo to where ever it goes??

    Problem 6: Occasionally the car will just stall. Mainly when i do a sharpish corner and then come to a hault. If it doesent stall it will just idle really low like 100 rpm's. Everytime i drive home my house is down a no exit street and it is right at the end so when i go around the coldersack i then park straight away after the corner outside my house everytime the car will idle very low after this or sometimes stall.

    Problem 7: When i stop at red lights etc very often the Stop sign will appear along with the other 3 lights (Coolant, Battery and oil) it will pop up but then disappear and then come back etc just at random.

    Those are the main troubles i am having with my peugeot 405 sorry to create a huge topic but i would really appreciate some diagnosis on what is causing these problems and what can be done to fix them. I know the car has a lot of problems but the exterior and interior is in mint condition and i did only pay 900 for it and i do drive it daily. It currently has 130 000 miles on the clock.

    Cheers for your help!

    Stephen,
    Your early 405 seems to have its fair share of the sort of problems the ones over here in Australia have also! In this country we only ever received the 405 from 1989 to 1993 (Series 1) as a 1.9 litre SOHC with Bosch Motronic fuel injection. These cars overall came to be remembered for their poor trim & tendency to have a myriad of annoying problems & the usual dose of Peugeot electrical gremlins. That said, I have owned two, and both handled well, with the superb chassis.
    Your noise coming from the area of the front passenger seat floor when you release the throttle could be a number of things from missing or loose bellhousing/transaxle bolts/worn engine mounts/driveshaft wear. It would be worth having the car up at the front on good quality ramps, with wheels chocked - or better still on a hoist - with it running & someone operating the clutch & accelerator.
    For problem 2 it would be worth assuring yourself the compression in all cylinders is good, as well as checking thoroughly the ignition & fuel system. There could be faults with the injectors performing poorly, inadequate fuel pressure & so on.
    For problem 3 it is all unfortunately too familiar to me & is generally due to Peugeots use then of shit electrical connectors. If you have the Haynes manual, follow it for how to remove things like the various switches & check the connectors. If they are dirty, clean them with kero & dry them. If they are loose, try to close the parts of the spring in the female connector, or replace the connector!
    For problem 5, it may well be the speedo cable BUT before going to the wonderful task of replacing it, undo the 10mm bolt securing the assembly at the gearbox [back of motor low between block & engine firewall - cable can be seen (with torch) descending into gearbox assembly] & pull to remove cable with plastic gear at the end. In mine it was the plastic gear teeth that were damaged just enough to make it cause the needle to flutter a lot. You can often get a good plastic gear wheel for them from a wrecker.
    Perhaps you could let me know what capacity engine & carb/injection system your 405 has before I go on any further?
    Regards,
    John505

    Cheers for the reply John.

    As far as i know it is a 1.9 Injected engine and to be fairly honest thats all i really know about the engine. It is my first car so i am not experienced with car maintenance.

    But what i want to do is give the engine and parts a good clean and check the injectors etc.

    This Haynes manuel i have heard a lot about what is it. From what i have gathered a book that helps with DIY guides for your car. Is there one especially for Peugeot 405 cars?

    Thanks Stephen.

    Stephen,
    Many models of Peugeot are covered by differing Haynes manuals. Haynes, is published by JH Haynes & Co. Ltd., Sparkford Nr Yeovil, Somerset BA22 7JJ of England. You need the Peugeot 405 1988 to 1996 (E to N Registration) Petrol Manual No: 1559. This covers most mechanical, body & trim problems in fair detail. The book can still be purchased new in Australia for around $50.00, but you might get a good (cheaper) used copy if you look around. They would be available in NZ I would expect.
    You will need to remove the injectors & have them cleaned. Best to take car to a fuel injection shop as they clean them in an ultrasonic bath, and then flow test them. If the injectors are playing up, they can cause difficult hot starting, persistent stalling, misfiring when cold, misfire when hot between 1000 & 2000 RPM, & generally poor performance.
    Details of how to remove them yourself are in the book, and let me know if you want to give this a go & I'll give you more info.
    If yours is a 1.9 litre injected model it sounds like NZ got the same car we did. Fortunately you don't have th automatic, as the transmissions had poor reliability with costly rebuilds. There is a three letter engine code[letters of alphabet] which you will find engraved on small metal plate located on the engine block just below & right of the alternator. The cars I had were both DFV (XU9J2) engines, & it would likely be the same for yours.
    By the way, they do use up to 1 litre of oil between changes, so do check the oil in between changes. Runs best with 10W50 mineral engine oil.
    Regards,
    John505

    Hey thanks for the info i plan on trying to hunt down the haynes manuel for my car.

    I also looked for that number you were mentioning there was two little metal plates screwed on the engine block the first one was pretty small and was black it had on it D2D Type Regi PTC the other was a bigger white one which had on it 1CW67 then below that in small print 504530 not sure what they mean.

    Not too sure what i am going to do about the injectors at the moment they might even be fine i probibly would be best to get someone to have a look at them instead of a DIY job not sure.

    Stephen,
    D2D is the engine code of a UK model & refers to the XU92C engine family (1905cc) built between July 1987 to February 1990 & upto engine No: 8274818 - your engine No is 504530. I don't know what thev 1CW67 refers to either.
    It is interesting that in Australia, every early 405 I've seen has a non-UK Model code - either DFV, D2C or DFZ.
    You might be better saving up & taking the car to a fuel injection specialist to get the injectors taken out & cleaned. Even if you removed them yourself (you need to disconnect the battery, slowly undo the fuel line where it joins onto the fuel pressure regulator, and then remove the injectors all attached to the common fuel rail after disconnecting electrical connectors) you would still have to take them to the experts to get them cleaned & have the flow pattern checked.
    The injectors, when they are working properly, show an even fuel mist pattern where the spray is around 60 degrees in all directions. Fuel injector cleaner added to the petrol every few months will help, but it won't unblock an injector that is severely compromised. The most important thing with fuel injection systems in cars like yours is to replace the Bosch petrol filter (located on the left side underbody near the front end of the petrol tank) every 40,000 to 50,000 km without fail. That is a job you can do yourself - don't forget to disconnect the negative lead to the battery! Have the car securely jacked with good quality axle stands supporting it BEFORE you get under it. Get the Bosch filter (often cheaper to source directly from Bosch that the Peugeot dealer - this also is true for the injection parts, oxygen sensor etc) - I pay $20 for these (recently went down in price) from a Melbourne French Car parts supplier - E.A.I Ltd. - www.eai.net.au). You need the filter with the small metal tube projecting from each end - so called "push on" type. It is messy job as you will always spill petrol over yourself! Cheers.

    Stephen,
    You may be able to get a cheap 405 Haynes manual on Trademe- the earlier ones are better and cover more stuff. They're good to start learning about cars.
    In regards to the thud on acceleration etc, how are the engine mounts?
    Electrics- the electrics on the english assembled 405s are shocking, french wire installed by poms. Most of the things are fixable by cleaning contacts and replacing the odd switch.
    Heater- it sounds like it has been bypassed. The heater core is under the dash and if it starts leaking it floods the footwell. Replacing it is a dashboard out job, hence the bypass.
    Speedo- yep, its to do with the cable being really long (and unlubricated) on the RHD cars. My '95 series 2 does it, I've never found it a major worry.
    Stalling- my car has a totally different engine, but I had a similar problem- it was caused by the throttle position sensor being slightly unplugged.
    The petrol filter on the 405 is available as a generic item- Cedele is one make- and shouldn't cost more than $30.

    Stephen, your car is carburetted not injected.

    The D2D or XU92C has a Solex carb. I'd say if you're really concerned, get it looked at by a Peugeot specialist, I've heard things like the float level often go bad.

    Your warning lights coming on then disappearing sounds like an earth fault. Apparently the earths on the 405s are of poor quality.

    As far as the speedo goes, my 405 speedo wobbles too but frankly I don't think it's worth the time fixing it. It's just a trait of older Peugeots.

    Sounds like the carb may need an overhaul or a serious tune up.

    You have to be careful when discussing 405s here because we essentially received pure UK-spec 405s, i.e. some carb models and full-compression motors. Whereas in Australia they received low-compression motors and there are subtle differences in the injection systems they use, also the fact they have no carb 405s.

    My 405 is an SRi with L-Jetronic injection, I'm currently dealing with an intermittant problem where it will just cut in and out, when it plays up you could be sitting there idling fine, turn the car off and one second later it won't start. When this happens the fuel pump stays running continuously with the ignition on, not stopping after a couple of seconds like it should and does normally.

    405's certainly have their share of problems but for a late '80s car I find they're quite modern and the handling is superb. Seriously, the handling is a lot sharper than many more modern cars.

    Hey thanks for the replys.

    I had no idea the car was Carb i just assumed it was injected.

    I probibly will get the car looked at or maybe even sell it and get another 405 preferably one of the leather interior models.

    I also find the handling good on the 405 i can throw it around corners and it handles great (Not a boyracer in anyway but as most car enthusiasts i enjoy driving my car and testing its performance.)

    Anyone know where to get some videos of 405's boosting it? I have looked on the internet and cant find many at all.

    Cheers Stephen.
