    How to install a Check Valve/Non Return Valve in 2006 TDI

    Yes, I am having the same issue except my tandem pump on the BRM is fairly new. What happens is after sitting more than 8 hours (overnight), starting is not instant but requires priming. In my case, once it starts it runs fine and it can sit for 4-5 hours and start immediately without any issue...

    The Non-Return valve in fuel line

    According to a 2006 VW training guide for my car about the fuel system, the non-return valve is between the fuel filter from the tank and the fuel pump. It seems to be a mechanical spring of some sort. Assuming there is not one, how does one trace or find where the fuel pressure leak is in the line?

    The Non-Return valve in fuel line

    where is the non-return valve on the fuel line. This valve stops fuel from draining back into the gas tank when the car is off leaving fuel in the line for starting. if your car lacks fuel after sitting long periods of time, this could be it and in my case, likely is. This valve must be leaking...

    Car starts and dies quickly

    Ok, will try it. But, normally, if there is no leak in fuel lines, when the engine is off, does fuel remain in the line or drain back into the tank? If there is a leak, would it not have a start problem at all times, cold or not? So, this AM, activated the ignition 4 times without starting the...

    Car starts and dies quickly

    If it were a relay or fuel pump, why would it run and start up instantly after the engine has ran for even just 10 minutes? It seems this would indicate a pressure issue or loss of over a 8+ hr. The diesel pressure is important when starting. A bad relay or pump would ALWAYS be causing the start...

    Car starts and dies quickly

    After sitting overnight, a cold start will fail because it starts and dies fast unless I pump fuel. Once started, it runs fine and starts right up even if parked for hours. If I fail to start it, it will take about 3-4 tries and then it will start once pressure is built up. I suspect a bad...

    Bad injector symptoms??

    No that was replaced. After the injector was replaced, it ran fine. Hoping this will not be it again.

    Bad injector symptoms??

    From my understanding, the electronic part controls the solenoid. One of my injectors leaked pressure over a long period time of sitting, there were no codes but the mechanical aspect was failing to maintain pressure when starting. After a three tries, it would start and run fine all day. Even...

    Bad injector symptoms??

    The injector have a mechanical and Electrical component. The electronic side controls to the solenoid and may be OK, thus no code is given until it fails. The mechanical may fail to work well. In this manner, there are no engine codes, but the car is hard to start after sitting overnight and may...

    Bizarre Electrical Problems... Help?

    You have my sympathy, my 2006 just gave me electrical. When I turn the headlights off, the DRL and rear left side lights stay lit! everything else is fine- regular and hi beams fine.Like you, I have disconnected the battery until I can get answers.

    Bizarre electrical problem

    Simply put, when I turn off my headlights, the left side front and tailights stay lit. The right side turns off. This started to happen out of the blue. I should say the daylight running lights and taillight stay lit, not the headlights. The hi-beams work normal. Is this related to a blown...

    2011 model?

    Just wondering if anyone has opinion of the 2011 model TDI, I am looking at one for 10K. It has 106K on it. Any recalls? Seems like some have had their turbo and DSG flywheel go as early as 50K. Debating whether I should keep my 2006 (replaced the turbo and flywheel) with 215K.

    Does anyone have a valid answer?

    The coolant temp sensor was changed, as to coils, if the coil was bad or intermittant, it would throw a code. As I said, there are none. It would also misfire all the time, not just when cold. It seems to be temp related-maybe there is no answer!

    Does anyone have a valid answer?

    Many 2002 VW Jetta 1,8T, automatic, owners have had similar issues about to be described: When engine is cold, say overnight, and started then driven without warm up of 10 min, upon acceleration the car jerks or bucks some and\or seems to go into neutral (meaning, the engine does not stall, but...

    Turbo related question

    I have a 2002 VW jetta 1.8T, after the car sits overnight or long period of time and engine cold, it takes 10 minutes of idle to warm the engine before driving to avoid some jerking. if the engine is warm or hot, there is no issues with the car. I suspect that the turbo requires some heating up...

    Brake+ABS light & 3 Beeps

    Lots of 02 model owners have this issue. My question is: if you replace the ABS module and pump, is buying a used one OK? Why do some sellers say it only works with models that are without traction control? Is this anti-skid? I thought all VW 2002 models had both ASB and antiskid? Can i buy one...

    ABS pump and controller

    If your engine code indicates the ABS pump is bad, can I just replace the pump or do I need to replace both the pump and controller of a replacement? I ask because if just the pump is bad, I can detach the pump from the controller and use the non-defective original one. This way I can avoid...

    Anti-Skid and ABS lights

    In everyday driving around town, does having the anti-skid and ABS lights lit on the dash have any impact on driving? acceleration?Are they worth finding what the issue is and fixing it? I have read that when the anti skid light is on, the engine power is cut by 50% by the car computer. Is this...

    Kicking when cold and acceleration

    My 2002 gas 1.8T kicks a little when it is cold upon acceleration. Another odd thing is that when cold, it feels like the tranny slips into neutral for a second before into gear(automatic). Are these related? If the car is warm or has been running for 10 min or longer, NONE of this happens and...
