Hi there i am new to this site and have just got myself a c5 1.6hdi vtr, engine had gone so i have replaced the engine with an exchange unit, and used the cat etc off the new engine as the other one was fully of oil and gungy deposits so was the bottom exhaust flexi pipe.after replacing the engine car started great and after about 2-3 mins gave the car a couple of revs, then noticed message "depollution system error" and lots of smoke ( whiteish but quite smelly ) some deposits soot etc on the floor.

I was expecting a certain amount of smoke and soot from the exhaust as there must have been a lot in the exhaust pipes going by the amount in the cat and front pipe.

Can anyone advise me on this as i am a competent mechanic but this sort of thing throws me, i did disconect the battery and then reconnected it and it wouldnt fire then?

but that may be coinsidence and the battery is now on charge.

hope some of you have some suggestions

regards

Phil

Hi Phil

 

Welcome to the forum.

 

Could you tell us the year of your C5 as if its 2005 on it could be a blocked particulate filter or turbo fault

Hi Phil

 

Welcome to the forum.

 

Could you tell us the year of your C5 as if its 2005 on it could be a blocked particulate filter or turbo fault

 

Hi thanks for your reply its a 54 plate now i know the engine supplied is a peugeot but same engine dv6ted4, the cat has came with this engine and the turbo and all was fine when it was first started up, i did wonder as im writing this where is the particle filter and also there is a sensor wire on the catand that was the one off the peugeot could it be slightly different the sensor that is? also the only other thing i have done is the two steel pipes coming out the cat i have had to extend the rubber section as on the new engine the pipes went in the opposite direction so i had to extend them and bring them back toso they would reach the plug in connector i cant see that that would do anything? but i am open to any ideas cause this engine is so complex with so many sensors. i got a copy of a citroen manual and put the vin number in and it listed it as fap does this help

Phil,

The 2 steel pipes coming out the fap this is the particle filter go to a pressure sensor to monitor when the fap becomes blocked, You say you have extended the rubber pipes from these 2 steel pipes. If you have put the rubber pipes onto the steel pipes the wrong way round or have a kink in one this will throw up depolution fault because the sensor can't monitor the exhaust gas passing through your fap.

Pretty sure i havent got them the wrong way round cant see a kink in them? would that explaint the white smoke/ steam though?

Are you sure the turbo is ok ? I had one fail on a petrol Saab and that surrounded the car in a big cloud of white smoke.

 

Thanks for the reply when i first plugged my diagnostics in i had 6 error codes inc 1 for (a/c circuit voltage too high P1462) but i know one of the a/c pipes are broken so probably eliminates that.

 

other error codes are

 

P0402

P0193

P1351

P1351

 

 

BUT NOW after erasing the codes and a little run i only have one code now which is P1351 WHATEVER I DO no matter how many times i clear it only that fault comes up.

When i drove it it seemed to drive fine for a mile or so and then started smoking again i would say under load that it smelled oily.

Engine is fine sweat as a nut. but dont know if this error code is related or not to this problem.

Does anyone know what the code means and possible solutions.

 

Also thanks paul for your reply

 

Anyone know how to check a turbo and what common symptoms are as i havent had much dealings with them and need some guidance

 

Kindest Regards

Phil

The error code i have found is P1351 IDM Input Circuit Malfunction/ Ignition Coil Control Circuit High Voltage

what this means in plain english god only knows?

This code is for glow plug relay open circuit this is from autodata, for your car did you scan your car with an elm scanner because mine comes up with this when i use the elm. If i use the lexia the code then comes back as p0380 with the same Glow plug relay fault. Since found out that even if a glow plug is faulty it will throw up this code aswell.

It was with my standarn plug in hand held scanner, but im right in thinking it would have nothing at all to do with my problem is this correct?

 

Also is there anything i can check on the turbo to see if it is that causing the problem ?

 

Or has any body got any othere ?

just incase you missed it please view my earlier notes i added a lot of info thanks and i am very greatful for your suggestions.

Phil have you used the old intercooler from the old engine if so make sure its not full of oil, take it off the car and wash it out in parrafin. Also could be oil in the exhaust just burning off when it gets hot and it will take a few miles to fully burn it off, are you losing power when the smoke starts??

Thanks yes im useing the old intercooler ,it hasnt been cleaned out. i thought about oil in the exhaust just burning through but i took it for a run when it had warmed up and for the first mile or so no problem then on the way back it threw smoke out. and i would have thought if it was going to be burning ***oops*** out the exhaust that it would do it from first off untill it had all gone not when it feels like it.

can you tell me what the intercooler does as i thought oil ran through it anyway?

seems low on power too

The intercooler is to cool the air from the turbo befor it enters the intake it just passes air under high pressure, a small trace of oil inside is normal but if you have a fair amount of oil in there it will get blown into the intake and cause your smoke. Take it off and wash it out to be sure, you need to do the things that ain't costing you money first.

that is a very good idea i understand now and it makes sense. The blown engine was pouring out oil through exhaust turbo had blown and i think big ends gone too, there was oil in the intercooler pipes definately and i think there is a unit on the left hand side with about three sensors and pipes coming out im tired now but think they went to the intercooler there are two butterfly valves in this unit but it was cleaned out properly so im thinking the intercooler! it would be great if it were just that.

so i think there is a good chance the intercooler has got a lot of ***oops*** in it i will check first thing in the morning, if you come up with any other ideas before then i will read them in the morning once again thank you

 

kindest regards

Hi there i have cleaned out all the intercooler and pipes etc and everything seemed to be good also could hear the whistle from the turbo so thought all was good let it get up to temp and took it for a run a couple of miles it started smoking again and i could definately smell the oil in it.

Took the bottom hose off the intercooler and there is oil in it again and also oil in the pipes leading from the engine to the intercooler.

Am i right in thinking this is the turbo oil seals or not? am i correct in thinking this is the only way oil will enter the intercooler or is there some other way or some other reasons for this happening.

 

P.s the turbo came second hand with the engine but was not guaranteed the intake fins seem to be fine no play freely moves so i think the turbo is working?

I look forward to your reply.

It looks as if it could be the turbo but Haynes does not really tell you how to check it other than to check for excessive shake or roughness when spinning. It runs in a film of oil but when the clearances get too large the seals (if there are any) may fail and lose oil. When ours went, removing the oil filler cap on the engine released a lot of smoke as well as the exhaust. Danger is if the turbo fails mechanically you may get bits of metal going through the engine and need to replace it again.

What does the smoke smell of also are you using any oil or water. maybe check up on the following the fap filter works on air pressure to operate the switch so by extending the pipes youve lowered the pressure to the switch.

Hi it smells oily and but not using any water, cant see ay difference on the dipstick to speak of but not ran it more than a couple of miles,

The intercooler has got oil in it as i said on my last post and could do with info of how the oil would get there is the only root the turbo? as there shouldnt be oil in the intake system any ideas please as i am getting dishartened with it.

 

i will look into the pipes but that wouldnt put air into the intake system would it?

 

Thanks everyone for your posts

Regards

Phil

what was wrong with the old engine as the oil could be left over of the previous engine as youve said your not using any oil. the 1.6 if not looked after properly with regular oil changes will gung everything up. had them with oil in the brake servo unit before and every pipe including the intercooler. You should maybe consider removing everything exhaust/intercooler/air flow pipes etc etc and clean the loot out with degreaser as recomended by the manufactures
