I would think if itsa diesel its your DPF filter sensors that is the problem. Is your "coil" light on?

Is it running rough like one cylinder is misfiring from a bad spark plug or injector, or is it all cylinders like from a bad air mass sensor or temp sensor?

    Then it is probably a sensor that is effecting all cylinders equally.
    The air mass sensor is one of the first ones to try.
    It works by measuring the heat loss, so if it gets coated with oil and water vapor, it won't work right. It will be like holding the throttle from opening.

    But there are temperature sensors, fuel pressure regulator, etc. also.

    Diesels used to be very different than gasoline engines.

    They always used to have a mechanical pump that could inject directly into the combustion chamber.

    The main problems then were water and clogged injectors.

    But I believe modern diesels have electronic fuel injection systems as well these days. But I am not too familiar.

    The first thing that comes to mind is the fuel filter, because diesel fuel always has a lot of water and wax build up.

    I have also seen a few were the exhaust had gotten patially plugged by carbon.

    Sorry I can't be more helpful, but I have no TDI experience.

    (Turbo Direct Injection)

    I hope there will be some people here with VW TDI experience, since the US laws make that about the only diesel popular in the US.

    The last remaining guesses I can think of would include things like a stuck wastegate that could be letting the turbo boost escape, or a bad temperature sensor for the electronic injection. I don't know what the ohms of the temp sensor should be, but when they go bad, they usually go to 0 or infinite resistance.

    You may also want to do a compression check. Deisels are known for head cracks since the high pressures. But remember not to use a gasoline engine compression tester. I did that once before I realized the pressure are so much higher. But I don't even know if you can, because I am used to using the glowplug opening. I don't know if you even have a port on an Octavia.

    Compression also makes me think of the valves. I don't know if there could be an adjustment problem.

    And there would also have to be a timing means for the injection.

    If it is belt driven, perhaps it jumped a tooth?

    Did the loss of power happen suddenly, or slowly?

    thanks once again. may be you are right. today they opened engine head and found valves were leaking. this happened slowly.

1996 camry lost speedometer and a/c while driving. Put in new battery and alternator, still no change and now car just lost all power while driving . What is wrong with car?

lost speedometer, what does that mean 0mph at 50? ??????
YES, CHECK all fuses first. all cars, for any electric issues.

A./c lost, (ok there are 6 things that cut A/c some are normal)
one is HVAC dash blower fan must blow or AC brain cuts A.C
this prevent ICE up. (normal)
why guess? please stop guessing and throwing parts and cash.
what does lost all power, driving mean.???
lost engine power (cant drive)
or lost all electric power (a prime reason for EFI to die , for lack of 12vdc electric power)
does lights die on the car, at the moment of problems?
Dash cluster , head lights, any lights.
does engine STALL? (0 RPM is stall) 300 RPM is bad idle.
800 RPM is normal hot idle, never less.

if this is just and engine power issue, (cant drive at all ,or only slow or
slow up hills?)O
my car will not move fast,? in any gear? and transmission don't slip
and no DTC scan codes (checked and smart to do first)

I'd be all over fuel pressure. this is a $20 gauge , that must be connected to the fuel rail to read pressure.
28psi is minimum for all cars.
if i knew what engine was in your car, id look yours up has this info.

the ecu can not report wrong fuel pressure, it cant
so is always and issue, with total engine power loss.
so is skipping 60,000 mile FULL TUNEUP's

if you need those charts they are easy to get. for any car.

tell more get more.... regards

They replaced my car with new battery but still stalling - no power at all. What do you think is the problem?


electrical power, as in dim lights
or engine power, like you can go up a hill fast wide open throttle
is it just quick loss of engine power or constant.
hot engine cold engine or both.?

stalls come on may ways.
1: lost DC electrical power lost to EFI system.
2: lost compresson, fails hot?
3: lost spark , try a 60k mile tuneup now, if skippped, they are critical.
4: bad fueling

there are simple tests for each failure path./
do you want to, do you have tools, ???? or just want guessing../?????

ok , i will guess, warning all of mine are wrong.
1: the Fuel pump regulator is bad stuck wide open and fuel pressures
is 1/2 spec at 15psi, car is gutless all the time.
one down 49 to go..
