View The Full Version : Polo 1.4 TDI problems starting
Hello to all guys I place this file to a polo 1.4 TDI that problems starting both hot and cold.Just under 90?,then, between 50 and 80?, while rarely the defect makes it cold.
then sometimes it dies when you walk slowly.
now I tried to do the usual editing as you can see in the file posted, but the problems persist even if with less frequency;according to you, could be a problem with the wiring of the injectors due to wear and tear?
thanks for any advice.
file ori here post 12
Filter diesel you know how, maybe the fuel of low quality?, have you had a diagnosis? I would start from there
For me ? the tandem pump.. if you disassemble you will definitely find a broken spring..
I have the same problem with the audi a3 cold and hot .......hot remove the problem, but then it is as well cold, and I also deleted the cold always from the map ....the spring in the pump tandem because what makes this spring?(audi a3 bkd edc16u1)
Have you tried to make a diagnosis
you made no error now I increased the map cold start, and part good but the problem I don't know what is??
for the moment, do not touch the mapping test to see if the fuel ec gasoline, it can happen by mistake, check the temperature sensor and see which value gives you when not part,then also check if the pump is in the tank when you manifest the problem, and if part controls the pressure of the flow,end if necessary check the relay that controls potrebbeb be heated.
I don't think the relay because it is now increasing from the map part of the sensors are located with the temperature, I checked the thing that made me felt bubbles in the pump tank and then is air in the circuit, the tank and clean the filter pump ... when you tap the map of what is going to increase the pump discharge tank , opening the injectors first?because when I raised part well even with serbatoii to dry....
excuse me, but why? we move on to the A3?
here we talk about the three cylinders 1,4 edc15.....I think it is more appropriate to open a new rear
then responding to those who intended to intervene on this engine:the car ? fully serviced, before you throw money in spare parts I wanted to see if the map and the problem disappeared, and in the case, proceed with the revisions to the mechanical....who has given a look to the attached map is a confirmation of that ? the solution for the start-up of the hot and cold?
thanks to all
the tandem pump brings the pressure in the injection system of about 6 bar, usually breaks one of the two springs and when it should be in start-up or when you ask a lot of load, the pressure is not ? enough
ok then, the lighthouse the test with the map, and then the revision of the tandem pump, it seems to me a very difficult job....
Guys sorry...that came out of topic you talk about cold start ....

I figured....
listen to does anyone know if c'? a way to verify that the pump is the problem of departures and off in gear?
measure the pressure with a pressure gauge, there is a hole on the tandem, where you can attack
injector that is pip?? watch if after leaving a p? still, the form is air in the fuel filter, if you take the 4 injectors from the pompista.
speed sensors, and phase are ok?
if there is a problem of diesel fuel each other, which is the pump that leaves a little, put a non-return valve and see if it goes better.
you in fact are the speed sensors, and phase replaced now the car does not miss a beat.....
thanks to all
quoto for the fuel filter dirty or replace...

In tandem you can check the analog gauge. Open screw 7 allen in tandem. Run car
At 850rpm 1.5 2bar
3.500 rpm 6bar. Check the pump in the tank and relay and timming vagcom chanel 4. Br
exactly the same problem were the speed sensors, and phase in some post I had posted the problem and then the solution..
you ? never turned off when you walked step of a man?
