Question about 2001 Volvo S40

1 Answer

I have a 2001 volvo S40 turbo. I had white smoke coming from tailpipe and in the egine compartment. codes were reading for bad wires and ignition coils. after replacing coils and wires, someone said t

The problem originally statred with the check enigine light and oil light flashing. Checked oil and found it was low. Once I added oil, and crank the car it began to put out trails of white smoke. The car never ran hot nor is there water mixing with the oil. Someone told me that they believe the o rings might be bad in the turbo causing the smoking. Just recently had the turbo taken off and placed the internal parts with a rebuild kit. Had the turbo replaced today and there is still white smoke coming from the tailpipe.

Does the smoke smell like burnt antifreeze or motor oil?

Hello
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

Would a blown gasket on the turbo of my Volvo S40 T4 1998 be responsible for a total loss of power and white smoke? Where is the turbo located??


WHITE SMOKE SOUNDS BAD COULD POSSIBLE BE A HEAD GASKET FAILURE, GET A COMBUSTION GAS TESTER AT AUTOZONE, CHECK FOR COMBUSTION GASSES IN THE COOLING SYSTEM.

Can coolant be leaking into turbo?


Yes that can be a problem. i had this happen to my 04 Volkswagen Passat. A bunch of steam and blueish smoke came from the exhaust. The problem was that the coolant seal in the turbo was bad and it was leaking. I had to keep putting coolant into the holding tank. Had the seal fixed and that fixed my problem!

Black smoke and bad fuel consumption what is the problem? Oh it an 07is volvo s40 20d


Hi there:Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor.
How did the fuel get into the cylinder in the first place? Some of the causes of excess fuel are a carburetor that is out of adjustment, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or computer sensor. If black smoke is present, check the engine oil as in the white smoke example to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil. Call your mechanic and advise him of what you have found.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa.

I have a 2001 Volvo S40 Turbo. Several months ago, My cars turbo didnt seem to be working. and the car was spitting and sputtering. I had the codes checked and found a misfire on Cyl 1 and 2. Or possible...


Replace the mass air flow meter.Thats the sort of problem you will get when its faulty.And this should be changed every 90.000.I think your fuel consumption has gone up aswell due to the air flow meter.hope that was helpfull.Good luck.

2001 Volvo s40 oil leaking in turbo, smokes white smoke and turbo not kicking in. I have a new head, timing belt waterpump, oxygen sens. valve job, cam pulley all changed. It is still smoking and no turbo....


Water in combustion chamber makes white smoke--suspect that the head gasket is leaking water into the chamber. If oil leaking around turbo, it may have a bad bearing and bad oil seal. Check waste gate valve and control.

Oil in the turbo, smoking bad!


check to make sure the turbo oil return pipe is not clogged. if it is pressure will build up causing oil leak through seal causing it to smoke.
