2008 V50 2.0d - Blue Smoke :(

[cwhaley]

Thanks for the help. Jobs this weekend are to:

- Check throttle flaps for sticking
- Test battery is giving a 12.6V or higher voltage when rested
- Clean out the EGR valve
- Replace camshaft sensor (as I was given a new one)
- General check of pipes and sensors

Not holding out hope but I don't think the garage would have tested this stuff. I will come back to post results.

I'm currently having the exact same problem also with my 2008 2.0d V50, tried out many of the things you did and still not solved, and I am out of options, so I am expecting your update! Thanks.

Started the car this morning and it was cold outside, cranked for about 5 seconds then spluttered and died, restarted cranking and had to rev it to get going. After a minute the idle was fine but the smoke lasted nearly that time!

Took ages to warm up but ran fine, nice and smooth!

I'll update you with my progress of my work. One other thing I will have done is a compression test but will need to book in at a garage for that.

Yeah my symptoms are exactly the same as yours. First started with slight shaking on startup for the first couple of seconds as the temps got colder, then it started spewing out bluish smoke and shaking, and then it got harder and harder to start up.
After the initial warmup it runs perfectly until it gets cold again and needs to be started.

What work have you done so far to look into the issue?

It could also be blown glow plugs

This morning the car was smoking even when driving which it hasn't done before. Not all the time but noticeable occasionally at low speeds. Engine temp was about 50-55 C after 10 mins of driving.

I've ordered a code reader which will arrive early next week, so I'm going to search myself for any codes being thrown. I also want to get a compression test done as the behaviour this morning makes me think it's a leak in one of the cylinders.

Replaced injectors and injector washers, cleaned MAF sensor, crankshaft sensor, throttle body, EGR, changed the glowplugs...

I'm thinking it could possibly be the glowplug relay - https://www.youtube.com/watch?v=qjA7hr-guFw (see video for location).

My mechanic is now mentioning a possibility of bent connecting rods which sounds pretty scary, but I'm sure there would be more symptoms as once it warms up after the initial startup, everything is perfectly fine.

Mine mentioned bent con rods too, but who knows! A mechanic at work says it sounds exactly like valve stem seals and dismissed the con rod idea.

I ran Forscan tonight and found these errors in the attachment. They mostly relate to air intake I think (Air Intake Temperature and Mass Air Flow) -- not sure if this would affect.

Hello, do you perhaps have an update? I am starting to be more and more afraid that it is the conrods, in which case this is pretty much unfixable, short of replacing the whole engine.
