find your local vw service center and see if they can plug their computer in to see if there are any codes on the cpu. there may be one for an intermitent for the turbo. i ran into the same problem last month and it was the turbo veins are sticky so occasionaly it lack power going up hills. it did not cause the check engine light to come on, but there was a code on the cpu when they checked it. if it happens again while you are driving, pull over, shut the car off for 10-30 secs then restart it and see if it makes a difference. when it happened to me i called my guy and thats what he had me do and it was like a new car after that.

Please clarify, Although the alternator light is on, can you start the car? Does it turn over, but not start? If it won't turn over, you 1st need to charge the battery and try to start it. If the light remains on, have your alternator checked, it probably isn't charging the battery. How old is the battery? If it doesn't charge up, it should also be tested to make sure it's ok. Let me know the answers to the above, and let me know what happens. good luck countrycurt0

SOURCE: volkswagen transporter 2 5 tdi white smoke

Hi, Luke

White smoke from the exhaust is typically oil burning, caused by, worn valve seal(s) - worn or broken piston ring(s) or a broken head gasket, thus allowing excessive oil in to the combustion chamber, but then most auto shops already know this and would require major engine dis-assembly to truly diagnose this issue.

Hard starting could be oil fouled spark plugs, a result of the same issue.

As a side note: I would take a friend who is somewhat mechanically inclined with you to "your workshop" to engage the person(s) to get an in-depth explanation as to how they checked your piston.

Do not purchase a fuel pump or that repair on an assumption, be sure

One of the tell tale signs of a fuel related issue is black smoke...

standing at the front of the car pull the cover off the left side of the motor and check the belt. No tools are required the check the belt. Cover pulls up and off. It's to the left end of the valve cover.

TDI 02 1.9 Jetta smoking and runs rough it sat for 7 years


When the engine sets, moisture can build up in the cylinders, causing rough walls and blow by past the rings. also seals can dry out allowing fluid and gasses to pass through? Fortunately, usually when you run it for a while it'll clear up. How long did you try to run it? Also if you have the same gas in it, that could cause a lot of smoke.

Have a test done on the glo-plug system as it appears that they have burnt out and are not pre-heating the cylinders or providing a source of ignition for the atomised fuel from the injectors

THE SMOKE YOU HAD IS BECAUSE MANY TRIES TO START COLLECTED FUEL IN THE COMBUSTION CHAMBERS AND SUDDENLY BURNT ON START. ANY WAY THE HESITATION OF CRANK START FOR LONG TIME CHECK WHETHER YOU DO NOT HAVE A PROBLEM WITH THE FUEL PUMP,FUEL FILTER OR COLD START SENSOR. CHECK YOUR SPARK PLUGS CLEAN THE THROTTLE BODY AND DO WITH SCANNER THE ADAPTATION.S

valve seals are going. when car sits excess oil gets past the valve seals then when you staRT up it burns the oil off then runs fine and no more blue smoke.

Jetta tdi 2007 running rough on start up at times. blowing excessive amounts of smoke from exhaust at times. poor idle at times feels like running on three and a half cylinders, takes a few seconds too...


You may want to check the ignition system. The smoke could be because of unburnt fuel. You may be running on less then 4 cylinders. Check if all spark plugs are firing. You may also want to use a scanner if there are error codes found in its ECU.

Starting issues starts fine one time next time won't start


I would start by changing the fuel filter out on the top of the pass engine compartment.  If that doesn't change a thing next I would look at the EGR valve operation.  Sometimes it will stick and cause a no start.  Lastly check to see if you have any possible fuel leaks from injector pump and lines off pump.  The system could be bleeding down.

2003 vw jetta wolfsburg bogs on early acceleration


Don't know if it applies to your diesel but most later gas engined vehicles have a 'cold start' valve that supplies additional fuel to the fuel/air mix along with boosting the idle speed until some warming of the engine is sensed.
