Car Forum / Peugeot Cars / October 2006MY406 smokes
Hi I have recently bought a 1998 Peugeot 406 diesel that has done 150k it has a good service record but the problem is that it kicks out a grey ish colour smoke when I accelerate don't look so bad during the day but at night it embarrassing,She drives fine and doesn't use any oil or loose any water.the smoke smells of diesel. I've put some injector cleaner in the tank and also some stuff called stop smoke in with the oil. Can you make any suggestions at to what the problem could be? Respects Gregg Try changing the oil and air filter these will usually improve things. It is also worth giving the engine a good burn in second gear at 4000 RPM as this will clear all the crap out of the exhaust system as it becomes hot.

Could be a number of things causing it to smoke, Oil and filter are just one, injectors are another , fuel contamination,? air filter,? valve stem oil seals,? worn rings,? to much oil in the sump, these are a few causes, I would find a diesel specialist in your area and ask his advice,,, could save you a lot of time and money,, I sometimes get advice from my local bus depot mechanics....they are usually spot on... !!!!!

Hi Fitzy Thanks for your advice. I had a local garage look at it a few weeks ago and they told me that the engine was good as in starts fine and wasn't using oil, So they thought that possibly at some point someone had put to much oil in and that its burning it off. As the car only smokes when under load and when hot. The only thing that concerns me is that the smoke smells of diesel not oil. I've done a few miles now and I love the car to bit's but she still smokes. Ps Do all these cars sound like a bag of nails shaken in a tin can when cold!

I had a local garage look at it a few weeks ago [quoted text clipped - 6 lines] > cars sound like a bag of nails shaken in a tin can when cold! > Respects Gregg As you have changed oil and filter did you change air filter? If not that would be worth trying. The garage was correct if it starts and does not misfire at idle everything is more or less OK. The other possibilities are - tight valve clearance - pump timing - this is sometimes adjusted to increase performance but it also increases smoke possibly wear to injectors. If you decide to change injectors use a local diesel specialist for replacements - never buy new injectors they are unnecessary. Always use service exchange from a specialist - not knowing where you are if in Greater London use Watson's Diesels in West London. You mentioned smoke looks worse at night this is a bit of an optical illusion it is no worse just that car headlamps show the particles better at night PhilC Hi Phil Yeah I'm going to try injectors as have changed all filters and oil, and tried all the cleaning/stop smoke etc jollop's that's on the market. I have found a company on the internet that do a recon set for £130 does that sound about rite. Respects Gregg > > Hi Fitzy > > Thanks for your advice.

Just been informed it could be something to do with the waist gate valve on the turbo!! and could be causing the smoke problem (could life be that simple I ask myself) respects gregg > > JUST NOTICED THAT THERE IS A LITTLE PIPE (PART NUMBER PA6.6/GF30) THAT > > HAS BROKE AWAY [quoted text clipped - 40 lines] > brakes.so you dont have to stand on the pedal. > chris Addlestone > Hi Chris > Yeah I see a little pipe running front this switch to the servo but [quoted text clipped - 50 lines] >> brakes.so you dont have to stand on the pedal. >> chris Addlestone So its time to look closer very close, are you in a garage or outside with a very bright light. Fitzy You are looking at the vacuums system that actuates the turbo. This is controlled by a solenoid switch. The vacuum system starts at a vacuums pump on the cylinder head, it then feeds the servo to improve your braking , it then feeds the cold start device that acts like a choke on a diesel operated by solenoid valve, the last item in this circuit is the accuator for the turbo again a solenoid valve. The pipe that usually fails is the one to the cold start device. Failure of these pipes will also cause braking problems as the servo does not receive a full vacuum. If the pipe you refer to is broken your turbo will not be cutting it at 2000 RPM.

It did a reasonable mpg and passed emission tests so it didn't bother me (much). I wondered if there was something about the red rear lights showing it up more as it was invisible in daylight. Have you tried just dipping the rear view mirror ;-) jim.

Hi Gregg Only just caught up as it happens I live near Woking - just up the road - and have the socket for changing the injectors. More than happy to help .......... As you have mentioned a misfire I am almost certain you have a tight valve - if you want to try another set of injectors I have a spare good set but you will need to get washers - run out. The email address is good if you want to contact me Phil found a broken pipe on a solenoid type thing at the rear of the engine I've been told feeds the brake survo and the turbo for cold starts. its an item that has 3 areas for pipes to run from but I can only find two pipes? any idea what or where the third one should go. am now fitting new injectors and the first injector has a wire running from it but isn't plugged into anything? have had a good look round the engine area and cant find anyware it should plug into? any suggestions anyone > > Hi Jim > > Unfortunally I'm old school and tend to be a bit conscientious,But I [quoted text clipped - 35 lines] > > Phil > found a broken pipe on a solenoid type thing at the rear of the engine > I've been told feeds the brake survo and the turbo for cold starts.

Hi anyone know what the valve clearance should be on my 406 lx dl 2.1 and what sort of job it is. respects gregg > > found a broken pipe on a solenoid type thing at the rear of the engine > > I've been told feeds the brake survo and the turbo for cold starts. [quoted text clipped - 46 lines] > Take your time when doing the injectors.also did you have a word with > watson diesels about your engine? Gregg Had another thought, the 406 uses 2 things to improve emissions in the UK 1) a spring chamber attached to the air cleaner box this prevents flooring the throttle and causing black smoke. Has the throttle cable been replaced and this spring unit left out. 2) an air damper on the pump itself. Again reduces the ability to floor the throttle and produce smoke. With the age of these models I doubt if this unit is working and can be removed with no ill effects unless you floor the throttle. These are very costly to replace.

Hi Mike Thanks for the info ill get looking. I've noticed that the car has an intermitent knock when cold and comes and goes? I've been told its a diesel knock!! could all this hasle with smoke be an air getting into the system?? > Gregg > Had another thought, the 406 uses 2 things to improve emissions in the UK [quoted text clipped - 72 lines] > > > Take your time when doing the injectors.also did you have a word with > > > watson diesels about your engine? Gregg My 406 1.9 TD sounds like a tractor until the oil warms up then quietens down. I have had it since new and it has always been like this. There are two places air can get into the system. 1) into the fuel. This will usually cause starting problems. 2) into the air intake system this usually causes a whistle which varies with engine revs. Mike > Hi Mike > Thanks for the info ill get looking.
