Another little update. Over the past couple of days I've been driving and it seemed to me that the smoke/steam issue was getting worse. So much so that people behind me were flashing when I was stopped at junctions or pulling away... Still No mayo, no water loss, no bubbles in the tank, no overheating.
I started to wonder if it was due to the fact I had put in a whole bottle of injector cleaner with a too little percentage of fuel (25%ish). I topped up yesterday but of course didn't expect to see instant results. I had heard and read and seen that injector cleaners will do this, sometimes more so than I have experienced. So today, finally decided to wash the car at the car wash. Pressure washed under the engine bay a little, the tip of the exhaust pipe, but not down it. After driving off, it could be me just missing it, but im certain that all of the smoking had stopped! It's early days yet but for once, I felt rather positive! I got home and with the engine at full operating temp, took the cap off and filmed the water. No bubbles, no oil. Fingers crossed I guess. It's due into Volvo on Tuesday for the pipe fix. I might ask them to test the water/tank for emissions. On another note... It's rather cold here, as to be expected in Sweden at winter. When starting up, the revs hold high, as I've experienced with any other car and as I expect, but being an auto, the car trys to launch away from standing when put into reverse or drive, until it's warmed up, of course. Feels kind of dangerous to me, I think I look like a fool too, like I can't control the car. Is this normal in autos? Should I be concerned? |

Hi Sam,
I bet it's your turbo oil return pipe/seal allowing oil onto the hot downpipe! I think I may even go as far as to put money on it! On your last note...service the throttle butterfly valve and idle air control valve.

Hi
It is indeed leaking. But it doesn't quite make sense with how there's white steam coming from the exhaust itself. But yes, that's what it's booked in at Volvo for next week, they gave me a quote that couldn't be turned down. Regarding the butterfly valve and air control, how would one do this? I'm a little rusty when it comes to petrols. |

Well...burning oil will produce whitish smoke...add that to the hot healthy toxins flowing from your exhaust, into a freezing atmosphere, will leave a trail in your wake.

When an engine is cold the idle revs are set higher until it warms up and slowly returns to normal idle. The faster idle will engage the autobox in exactly the same way as lightly pressing the throttle with a warm engine.

Another update... She's begun to steam a lot from the exhaust again. It seems to have come on gradually since cleaning the car (which I thought stopped the steamy issue) Anyway, into Volvo tomorrow to fix the oil return pipe. Hope that makes a difference. I will change the oil and filter next Sunday.
New issue that's got me puzzled. The passenger front footwell seems to never clear from water. I never sit there and haven't had a passenger yet so it's a bit odd. Took the mats out, washed them,dried them, but a few hours later it had a small pool of water again. No leaking from the door or bulkhead area, the interior carpet stays dry too... I Have a moisture box/dehumidifier in the car but it can't seem to cope with this amount of water. |

Hi all
New update. The cars been to Volvo, had the seal and gasket to the oil return pipe replaced. Can't say for sure yet but I'm guessing the leak has gone. It's been to much snow and too wet to get under the car and tell for sure. But, it only cost me 1000sek which is less than £100! I was shocked. Smoke/steaming issue is still there, getting worse, if I'm honest. But, I purchased one of those testers off ebay which uses fluid and some odd device to show if gases are present in the water. Ran the test for 6 minutes, as directed, no change to the water. Turned car off, back on, ran it again at high revs, nothing. As the water hasn't been dropping and this test would seem to concur, I don't think there's a problem with the coolant system. Great!... Or is it? Now I'm not sure what the issue could be... Ive looked up overfuelling symptoms and I'm wondering if I could be that. As the car pulls well, doesn't splutter, I had doubted the maf sensor. But a false reading from that could probably tell the engine to fuel harder or confuse the ecu to the outside temperature... Im also wondering about the lambda sensor/s, probably original, probably done heir life, but could that cause overfuelling??? Footwell wetness issue seems to be ok. Drained The water, dried it and it's staying dry, just now. Another odd thing that might help diagnosis in this situation, sometimes, usually after I've taken a short drive, perhaps out for my lunch etc, when I get back in, it takes few seconds to start, almost like it's struggling to push fuel in. After longer drives it's fine, in the cold mornings it's fine, only seems to be between short distances. |

Or possible Engine Temp Sensor sending out incorrect info to the ECU. Do you have a multi-meter to test the sensor for resistance (Ohms)? Is it heavy on fuel? How quickly does it come up to normal operating temperature (92°) and does the gauge sit at 3 o'clock?
