SOURCE: smoke from the exhaust when starting

Sounds like it could be valve stem seals. That is the classic symptom if the smoke is blue.You can get the same symptom if the oil drain is plugged at the back of the head with sludge or those flat round oil bottle seals that are on the top of the bottle are notorious for falling in there during an oil change and working their way back . That is possible too.If the drain is plugged the valve cover will fill up.Stem seals are designed to remove small amounts of oil splash. They are not designed to handle submersion. The result smoke at start up.

SOURCE: car smoke white when idle and nothing when driving

Engine also smokes when car driving if turbocharger still faulty. Did you change the engine timing belt (the timing belt kit) meantime? What about engine oil consumption? When engine glow plugs (one or more) burnt then engine exhausts white smoke at idling. Also white smoke at engine idling when water is still present in diesel fuel.

SOURCE: Audi missing at idle, engine smoke, and vacuum leak

audi oil leaks are usually valve cover gaskets. oil run off causes smoke on exhaust downpipes.while vacuum hoses do tend to dry rot with time it may also be the secondary air injection pump (if cold ) or waste gate for turbo.try to use a long hose,put one end on your ear use the other to locate sound. extending mirror and light may help too. missing at idle could mean time for tune up or coil pack failing. good luck

SOURCE: BLUE SMOKE FROM AUDI RS6 ON DE ACCELERATION AND

General rules of thumb: Low speed engine on acceleration with smoke in the exhaust plume = worn piston rings High speed engine accelerating (spooled up turbo) with smoke = oil form turbo bearing and/or piston rings Engine on over run (coasting down, foot off the gas) with smoke = oil from valve guides. VW/Audi make good engines with tight tolerances so none of the above should apply at 62K miles; just make sure that the oil (the right oil) and oil filter are changed regularly.

Why is my car blowing white/blue smoke after standing in idle for extended period. no smoke present while driving.


Hello Barry, Two causes for your problem comes to mind. Smoke after initial start up and/ or extended idle could mean bad valve seals. Some time ago I had a car with a leaking vacuum modulator on the transmission. Intake vacuum was sucking the trans fluid into the intake manifold. Your car may or may not have a transmission modulator. White smoke usually means it is burning engine coolant.

Blowing blue smoke


Hi can you tell me make and model. Does the car blow blue smoke all the time and other than smoke any other symptons? poor starting , power loss etc.
I had a similar problem on a golf gti after servicing drove very well but smoked on start up, and found to be the high grade fully synthetic oil recommended by the factors was simply too thin, and thus giving me by pass on worn valve seals and pistons on older engine sometimes a thicker grade oil is better.

Hi,recently noticed a smoke(smells like exhaust smoke) coming from underneath my drivers side wheel arch when I start the engine on my Audi A6 1.9tdi.What could be the problem..?


There are couplings that hook the manifold to the exhaust.... flex pipes.. about the size of large can of soup... they allow the engine to flex when you punch the gas.... they meet on both sides right underneath the bottom of the engine.... Google "audi a6 flex pipe" you' ll see them on ebay..... its the braided part... Go anywhere but MIDAS! to have it fixed... about $225 per side... That's what my problem was...... good luck

Ive gota 2006 audi a4 sline when a oil pressure light came on it stil drives does not rev over 2000 revs and throws alot of black smoke owt what isit


Black smoke is a sign of excessive fuel, there is something wrong with the fuel injection or one of the sensors which is sending an incorrect signal to the unit, perhaps it is still inn start enrichment. The oil pressure switch could be linked to the start system and the switch is either faulty or the engine oil pressure is failing.

I just bought this tempo it starts but after i have been driving for about 20 min it starts to smoke and it starts to get hot it stops then you hav eto get a jump to start it.


It sounds like you have brought a lemon as if it hard to start when cold then its lacking compression which is worn engine piston rings and valve guides,and if it starts smoking when driving and if its BLUE smoke then its bad piston rings And if its BLACK smoke then its to much petrol getting into the engine which will also cause the engine to wear out quick as its washing the bores with fuel instead of oil,and that will also stop the engine from starting when hot,
SO if its BLUE smoke replace the engine
If BLACK smoke repair fuel fault.

Audi 1.8T sport Auto (2001) heavy smoke and engine buring smell


The engine could be shot, oil is being burnt off by the actions of being sucked into the bores via worn piston rings then ejected out of the exhaust

If you sent the car in for an MOT and a Service I would ask the garage what they did to it as the car would have failed on its emissions test if that much oil was coming out .

It could have been a fault on the oil pump or lack of oil in the first instance and maybe an overfill on the service

You paid your money now go back for redress
