V70 black smoke-

Fanchuan · Oct 15th, 2018, 18:14

Hi guys,
I bought a 2004 v70 d5 last month, and last week to prepare for a long road trip I had the oil and oil filter changed.

After driving for two hours on the motorway the car started to smoke like a chimney. At the time I thought it was white smoke, and I assumed that the mechanic had over filled the oil. After stopping at a service station I found that the oil was about 1cm over the max fill line.
As you can imagine I cursed the mechanic, and drove home leaving a smoke screen reminiscent of something from Wacky Races.

To try and minimise any damage the next day I drained about a coke cans worth of oil via the dip stick port, and went to see the mechanic.

On the drive to the garage I found that the smoke had turned from white to black, and only occurred under acceleration. The mechanic revved it himself and a lot of black soot shot out the exhaust. He then told me this was normal for a diesel and told me to wait a week to see if it stopped smoking on its own.

I checked the oil level at the mechanics and found it was about 1 mark under the max fill line.

Before I changed the oil the car was perfect. I had taken it on a couple of long drives and it was faultless, it has about 170 thousand miles on the clock and apart from the smoke it is a lovely car to drive.

Any help or advice you guys can give would be great. I reckon my best course of action is to take it to a different mechanic and have another oil change, what do you think? (What type of oil do you recommend?)

I guess it's a Euro 3 engine (D5244T).
The recommended oil is A3/B4 0w-30 or 5w-30. Do not put C3 or A5/B5 oil in it.

Many thanks bkulcsar

I think it is a Euro 3, it has the black engine cover. I will put the recommended oil in the next chance I get.

Hi Dave, the coolant level hasn't changed at all, so fingers crossed the intercooler is OK. Thanks for the suggestion though. I am starting to think that my mechanic just stuck any old 5w-30 oil in, not the A3-b4 stuff

The intercooler has nothing to do with the coolant,
I think any 5w-30 would not smoke with lots of soot if intercooler was ok, look for a air leak on boost pipes,
Look where all of the coolers are, and under the coolers, you need to undo a plastic tray under the coolers to see, if there is any oily muck there, it is a blown intercooler,

I’d second daves reply above, it sounds like the intercooler or possible one of the inlet hoses failed.

I would like to clarify something to the OP

The intercooler is an air cooler which cools the compressed air which has come out of the turbo before it goes into the engine, if it has a leak (which is very common) then the compressed air escapes and the car over-fuels as a result presenting black smoke from the car. It's situated between the coolant radiator and the air con condenser at the front of the car

Please don't confuse this with the engine cooling radiator which does a different job entirely.

Thanks Dave, I will take a look at the boost pipes and the intercooler tomorrow. I hope it's a pipe-- I have a feeling a new intercooler will cost a small fortune.

new intercooler will cost you about £100 , if you fit it yourself and don't buy from Volvo,
