white smoke diesel

[smiffy180]

I've read up on it and that it could be a few things, from checking the video can anyone point me into the right direction rather than buying parts and hoping it works?

It only happens overnight after car has cooled down

Recently had dpf removed and only noticed it since then

Did the garage remap the ecu to delete the dpf programming? If not it'll still be trying to regenerate hence the white smoke when it injects extra fuel for the regen.

It wont be trying to regen from a cold start

And in answer to the question, it could be unburnt fuel, it starts up nicely though.

So rather than being a dick as I missed the bit re it being a cold start you could possibly actualy contribute.

OP get a leakdown test done on the injectors. Valve stem oil seals may be worn also.

Does it use much oil ?

What car is it ? - Fiat 2.0 diesel

As above, either there is an oil leak into the cylinders via the valve steam oil seals, the turbo seals are leaking slightly once everything is cooled down or one or more of the injectors is leaking very slightly.

Monitor the oil level for 1k and see how much is uses

Leakdown test? I assume any garage can do this?

It's a 09 fiat bravo 2.0 diesel
Checked oil a few days ago as I thought it was blue smoke and it's fine

If its not using any oil don't bother with a leakdown test, take it to a diesel specialist and get them to check the injectors.

My 320d does this every morning, and has done for the last 12 months

Saying that, it has used a dipsticks worth of oil in about 5000 miles.

Im guessing this is not normal...

[anonymous-user]

My guess is one or more failed glow plugs.

Hmmmmm. There is a possibility it is using some oil but I haven't noticed. I'll check again in morning as tbf it was serviced about 3 month ago.

If that fails I'll find a diesel specialist like you suggest

This was my first thought but it hasn't been cold enough to see if it struggles to start yet

[smiffy180]

Just thought I'd bump this, went to a garage and had a chat about the car and dpf delete etc. They said it's nothing to worry about, suggested its because the dpf has been deleted that the smoke has appeared.

That's how mine (totaly differant car, older but still a TD) looks cos it has a glow plug down but it also misses, it stops smoking as soon as the missing stops, does your miss whilst smoking ?

Sounds perfectly fine to me?
If it struggles in winter I'll know what problem is then (hopefully)

Diesels white smoke when they are cold, there is nothing wrong with your car.

[vrooom]

Buy petrol engined car. That should solve your problem

White smoke on start-up is not normal. It's an indication that raw diesel is coming through the exhaust.

White smoke = unburned diesel. I can only think of:

i) Failed glow plug/s - White smoke should abate fairly quickly after cold start. Solution to test glow plugs & replace any not working properly.
ii) Condensation rather than smoke - sorry I can't view video here (work) so not sure what smoke looks like, but moisture in the exhaust from cold, more apparent on damp/cold days.
iii) Fuel atomisation problem - e.g: Injector blockage/wear/fuel pressure inadequate. Get injectors tested and cleaned.

Ignore the calls that it's oil, they're wrong. Oil smoke is blue, not white. I'd suggest a leaky/sticky injector perhaps? If it runs alright then I probably wouldn't worry too much about it.
