    Hello.

    My car is T4 1.9TDI from the 97th year and I have a problem firing it "in the cold". It turns, but it doesn't even fire with Poster.

    Steps taken:

    1. Replacing the glow plug fuse (the one on the mudguard to the right of the battery). In general, I have already combined with it several times, I already had 30A, 50A and 80A there and smoked on each one - I currently have 30A - by the way, does anybody know what should be there?

    2. Glow plug relay in fuse box checked - transmits current to the candles.

    3. I changed the fuel filter because I read it here. And by the way I noticed strange air bubbles on the line from the filter to the pump so anyway I did something useful because I never exchanged.

    4. Glow plugs were replaced 1.5 years ago those "more decent" and defend it like fire because access is difficult and I cannot transport it to a mechanic.

    5. I also replaced the ignition key because I read it here.

    6. The battery is Centra Futura 760A, it is two years old so I rule out its failure.

    In general, I was convinced that the problem was in this filter, but even after the exchange did not even light with Poster. Today, after spending the whole day in the cold, I got hit, that's why I'm writing here. I noticed one more strange thing. Once, when a buddy could not start the car, he was spinning and repairing a good 30 minutes almost constantly turning and the battery did the trick. As for my ride, there is probably something wrong with it - after each battery charge I have ONLY 3 attempts. I spin 3 times for 7-8 seconds and the starter stops spinning, the clocks zero, the lights flash and the end - again under the rectifier. Today I bought a multimeter and checked the electricity at a standstill (because it can't be fired) and shows me 12.55 even though I have no more power to spin. I remember from a year ago that I had to recharge my battery and it lasted about 15 hours - only then was it full. Now it takes an hour, max 1.5h. Why is this happening? Can you suspect from the very beginning the problem was with the starter? Or from aku? Or maybe candles? I will add that I fired it the day before yesterday because it was +1. He fired up very hard overall - I added gas and waved the handlebar on the left of the steering wheel but I still don't know what it is called professionally. Some say choke, others say fuel injection accelerator. It doesn't matter, it helped ... I am asking for help ...

    PS. From a week ago the situation was the same and I was able to fire it in the hall but it was very difficult. More difficult than usual - after 2 kilometers I was tired of something on the bank, something was wrong - in the past I was able to push myself, jump into it for a quick and normal start - even on a cold one.

    check compression first

    You have to replace the battery. It no longer has its capacity, hence the inrush current is also small. This problem may affect the desire to start the cake. Starter speed too low. The rest for later diagnosis.

    The compression was checked, everything is fine ...

    The battery, then, somehow check in the service and let me know I am surprised that the "home" meter shows good voltage after charging and additionally barely because it barely but fires on a warm ...

    Well, the case is as follows. I checked the battery in the service and the guest said that my copy is whacked and qualifies for sending to the manufacturer because it is still under warranty. I got a replacement battery and it fired after 3-4 seconds of filming - it probably had a delicate problem, because I was replacing the fuel filter and I neither flooded the filter nor bled the system. Now, after 4 hours of standing in the cold, I fired after 10 seconds of filming with a problem, also in the morning a bode failure during firing. What now? Candles?

    Now check the charging and current consumption of the starter. It is possible that he caused the destruction of the battery.

    I do not believe in such "okay" from someone who can not cope with the diagnosis of the fault. Also show off the result.

    I drove with this new battery again to this service and checked the loading and layout. The printout made, said everything is ok.
    But I have no results, mechanior said it's "okay" so I wrote ...

    Supply the stop valve directly from the battery, the accelerator works?

    What should I do? :P
    Are you asking about the lever on the left of the steering wheel? It works.

    Colleagues want to eliminate the voltage drop on this valve, so connecting directly to the battery can make the test run easier. If so, the beam will be reviewed, or the relay may be added.

    There are a few ambiguities in what you wrote:
    1) since you have the accelerator "choke" it means that you have 1.9td engine and not TDI
    2) if I'm not mistaken, the TD candle has about 10A consumption, so the 30A fuse should be too small to last, unless TD has weaker candles
    3) since it is a TD engine, the right angle of injection is very important

    Starting engines for thrust is not a good idea. In addition, it is also worth looking at whether the pulley on the shaft is not giba, because it is a problem for droolers. 1.9td and strongly affects firing by running over the injection angle /

Topic summary

The discussion revolves around cold start issues with a 1997 VW Transporter T4 1.9TDI. The owner has replaced the glow plug fuse, glow plugs, and fuel filter, but the vehicle still struggles to start in cold conditions. Responses suggest checking the battery's capacity, as it may not provide sufficient inrush current, and verifying the starter's performance. After replacing the battery, the owner experienced slight improvement but still faced difficulties starting after prolonged cold exposure. Suggestions include checking the charging system, current consumption of the starter, and ensuring proper injection timing. The importance of eliminating voltage drops in the system is also emphasized.
