306 Dturbo smokes on startup.

pug_owner2002 · Post by **pug_owner2002** » 01 Feb 2006, 12:46

Hi,

I have a 1997 R reg 306 D turbo that smokes quite alot on start up (only when its been stood all day or night) and spluuters as well (a bit like a misfire on a petrol engine).
When thew glow plugs were replaced I used none genuine ones as they were cheaper.
Do you think that these might not be giving out a high enough temperature or is it more likely to be something else such as air in the fuel line?
The "misfire" clears after the engine has been running for about 30 secs on a very cold mornings.

Any thoughts/ideas appreciated before I go buying genuine glow plugs.

genuine glowplugs have little tips on the end .they also stay on after you have started up (post heat) untill coolant temp at 60 degrees.i would fit genuine every time.

the heating only continues for 3 seconds after the light goes out

it does actually stay on post heat untill 60 degrees after the engine has started.pre heat box has coolant temp info to it via 2 pin green sensor on thermostat housing.put a test light on glowplug supply wire and you will see.have been using this set up since facelift 405 with the xud9te in 1992.

Try waiting an extra couple of seconds after the glowplug light goes out. Alternatively, turn the ignition on and off two or three times (waiting for the light to extinguish each time) to give the plugs time to heat up a bit more before you turn it over. If this reduces the problem then you know it's the plugs...

Thanks everyone for the replys!

I tried what stevieb said and turned the ignition on and off a few times and this improved it.
So a set of genuine plugs it will be.

BERU glow plugs are the best ones to fit

Not all cars have this setup. My 1993 facelift 405 with XUD9TE doesn't have it, nor did the one I had before this one.

I think it's more often fitted to vehicles with Lucas/Cav injection pumps.

BERU glowplugs are definitely the way to go. They may be expensive, but they work and they last.

The only other problem that there could be with the engine (from the OP) is that it may be a bit down on compression. Running the glowplugs 3 or 4 times seems to compensate for this on a cold start. If you change all the plugs and the starting is no better, then this may be your next port of call.

this guys 306 dt will have post heat,needs this to meet L3 emmision standards,will also have a catalyst as well.

i have a 1998 S reg pug 306TD

it does not keep heating till 60 degrees (it has a bosch pump)

it does not have a cat on it (no diesel does - they are particle filters - says so at the peugeot main dealers)

306 and 406 diesels have catalyst only hdi versions have particle filters .i know i work for peugeot!!

if it is a cat , then why, when it is removed you do not fail an MOT test (which requires cars after 1993 to be fitted with a cat).

it isn`t a cat or it would fail if it is faulty or removed.

a petrol engine catalyst traps carbon monoxide and oxygen to produce carbon dioxide.a diesel engine cat helps reduce nitrious oxides by raising tempretures in catalyst and other harmul gases if a cat is fitted it will probbably have egr as well.if you remove a petrol catalyst it would fail the mot emmisions test,if you remove a diesel one it will still pass the smoke test
