  1. To diagnose the sensor, check in vag com, Measuring blocks, Group 007 which value indicates the temperature of the coolant. Checking is done in the morning without starting the engine with the contact only. All temperatures in this group should be almost the same. If everything is ok here, then the problem can be the timming. To determine if it is ok, check the second field in Basic Settings (BS), Group 000 (attention Basic settings not Measuring Blocks, are not the same). Read this and for complete the diagnose put some print screen with MB, Group 001, 004, 013 and BS, Group 000, all with cooling fluid over 80 degrees Celsius.

    Bank 1, Sensor 1 = pre-cat Bank 1, Sensor 2 = after-cat Bank 2 is for longitudinal engine with two exhaust manifold. https://static.cargurus.com/images/site/2015/03/24/19/52/pic-3585884633758656484-1600x1200.jpeg
  6. SDI Cranks but wont start

    First renew the fuel filter orings (elements no.5). To establish the source of the air in the fuel lines remove the hose no. 10 of filter and enter it directly into a bottle with diesel. If it start the main issue could be that orings.

  8. Timing Belt Kits Inc Deflection Pulley?

    Thanks for pics, very interesting. Currently I canceled the EGR valve and intake flap by canceling the vacuum and I feel better torque at low revs, but I see that it can be better. Your screen grabs looks good, but let's take them one by one: gr. 001: the amount injected at idle is a bit high ---> the consumption at idle could be a bit high (I have 0.3l/hour--->gr 015), low consumption in motion (my consumption) and the car can be a bit lazy. My engine has 2,4mg/str at 900C. It can be adjusted small limits with this method or in larger limits with hammer mod gr 004: Ok, but is interesting to know which is the value in Basic settings, 000 group, the second field. You can log any kind of parameters (Push Log--->Browse-->Start--->Done,close) at idle or walking ( very useful in this situation because you can record parameters without having to keep an eye on laptop ), but at start if the battery it is not in good condition the software will loses the communication with ECU due to lower voltage, so you need an additional source of power (another car) I attached some information about measuring blocks and how to test the N108 Observation: 1.It is more useful to attach logs to the post 2. I think we need a separate topic for the diagnosis of Lupo/Arosa diesel engines measuring blocks.pdf Checking injection timing control range.pdf
  9. Oil breather pipe missing, what do i need to do?

    The air comes from outside of engine bay for larger quantity of oxygen (cold air= more oxygen , in engine bay the air is too hot so less oxigen)
  10. Timing Belt Kits Inc Deflection Pulley?

    There is a sensor in the injection pump
  11. Timing Belt Kits Inc Deflection Pulley?

    Intake flap is on or off? How the flowed induction system looks? A pics, or a link because I am very curious how this system looks and how effective it is. I don't think the cat is blocked. If it is blocked...no power. How is the idle fuel consumption (group 015, the third display field)
  12. Timing Belt Kits Inc Deflection Pulley?

    In group 007 For a knocky engine can be both management causes and mechanical condition of engine. To determne the management causes the following is needed: if there are error codes Some printscreen (or pics), as a in the example above, to the following groups: 000, 001, 004, 007, 013, 015
  13. Timing Belt Kits Inc Deflection Pulley?

    Yes, it is a mechanism in the injection pump. It is known as N108 valve (no. 17 in below picture)
  14. Oil breather pipe missing, what do i need to do?

    That is not the oil breather pipe, it is connection piece for cold air intake
  15. Timing Belt Kits Inc Deflection Pulley?

    @mk2 I'll answer here because It was a bit offtopic on the topic where you asked: Yes, the ECU compensate a wrong timing adjusted, but within certain limits. I'll explain a little using my own engine. My timing is a little late.....a bit more. We can see this in Basic settings, group 000, the second display zone (this is my actual timing). This is not good. At this engine (AKU) this numerical value must be like in next picture but this is not a tragedy because the ECU working hard and working hard and we can see the results in Measuring blocks, group 000, the second display zone it looks like the picture above Yet no matter how much it is deregulated the timing and this can be seen in Measuring blocks 004 group. In this group numerical value in display zone 3 should be almost equal to the numerical value in display zone 2 and in this time the numerica value in display zone 4 must be in the middle of the range. My engine meets these conditions and did not beat my head with additional adjustments It is important to note that the starting ECU does not influence the timing so it is very important for a good starting the numerical value of timing in Basic settings 000 group. Fortunately my car starts perfectly with timing in all conditions as it is set now Last winter started to -20 celsius (-4 Fahrenheit) without glow plugs, hard but it started.
  16. What is this noise?

    To check the status of the injectors with VagCom / VCDS you can read the compensation of injectors in Engine / Measuring Blocks / 013 group. Try to mix some two stroke semisynthetic oil in diesel fuel (100ml 2T oil/20l fuel) and use fuel with 55 cetane number. After that tell us how your engine sounds. I use 2t for more than 4 years (approx 43k miles, EGR OFF) in combination with Power Service additive (occasionally) and engine sounds like new, and the compensation injectors are almost 0 If you have EGR OFF, this may be a cause for a noisier engine.

    They are not links, they are attached documents to post (in pdf format, to read them need to be logged in and you must have Adobe Acrobat installed on your computer). But if you can not read them nevertheless, I have converted to doc. Removing, installing and tensioning toothed belt.doc Checking semi-automatic toothed belt tensioning roller.doc Dynamically checking and adjusting commencement of injection.doc Removing and installing ribbed belt..doc Removing and installing ribbed belt1.doc To check the commencement of injection you do not need an VCDS too recent, a 409.1 vagcom is sufficient (of course It must have full functionality, not with shareware program)
  18. Timing Belt Kits Inc Deflection Pulley?

    I always changed all the pulleys of timing belt kit. You can also change optionally the ribbet belt, ribbet belt tensioner pulley, alternator pulley and coolant pump. It depends on their condition and requires an initial evaluation. I never replaced the coolant pump when I changed the timing belt kit (I replaced it once from error when the car had 124,000 miles, currently it have 205,000 miles). I replaced the ribbet belt tensioner pulley twice (one of them by mistake of course) and the alternator pulley twice (one was the real cause of the two errors) It might be necessary to replace the toothed belt cover, the lower part When I changed the last time the distribution, the cover looked quite bad ( It was deformed and scuffed by the sprocket ). I attached some documents and do not forget: after changing timing belt kit is mandatory to do dynamically checking and adjusting commencement of injection. For this it is necessary a vagcom or a vcds.

  19. Clunking noise

    Yes, you guessed right is Romanian language not Spanish, so you do not need to learn Spanish. But I need to learn English better to make me understand. For a long time I had a noise when passing over bumps or curves (It sounds like something hit the bodywork). First time I suspected that rubber doughnuts. But some time ago I fixed the exhaust pipe (I replaced the muffler) and I noticed that exhaust pipe was not centered correctly due the grip from the front of catalyst converter. I fixed it and no strange noises. In conclusion I suggest you first check centering of the exhaust pipe (shake the rear silencer vigorously in all directions: do not have to hear blows in the bodywork) Of course it could be other causes, but this is easiest to check (visual inspection would be welcome) If you want to translate some passages of my topic I will try, but not very soon because I'm very busy.

  21. First I apologize for my English, but I hope you'll understand. There are several possible causes for your problem: EGR valve blocked open or which closes not ok. The causes for this are: - clogging of EGR (rare cases): for check, connect a piece of fuel hose to EGR and simulate the vacuum ( pull air with mouth); the EGR's diaphragm must move and when release the vacuum you must hear a "clamp" - vacuum when is not necessary. For this is responsible N18 solenoid. Check the air filter ( arrow 1 ) if it allows air to pass (if not, vacuum will permanently be present at the EGR valve, this will permanently be more or less open and you can't accelerate the engine over 2-2.5k). Second check the N18: disconnect the power plug ( arrow 2 ) and remove the hose from EGR valve ( arrow 3) ; start the engine and at idle should not be vacuum at hose of EGR.That apply 12v to the N18 solenoid by means of 2 wire directly to the battery ( polarization is not important but be careful not make any short circuit, it is recommended put a fuse on a wire ). In this situation the vacuum must be present intake manifold flap change-over valve -N239 blocked on closed. The role of this flap is:at low engine speeds the vacuum in the intake manifold is not sufficient to ensure correct functioning of the exhaust gas recirculation system.Therefore to increase vacuum the throttle valve remains closed up to approx. 2200 rpm after starting the engine. For check: remove the intake hose and observe if you increase the engine speed to over 3000 rpm the flap will be completely open. If the flap is not closed at all times at idle is not an issue. obstructed intake manifold, like this to clean the intake holes I have used this home made tool and after this I aspirated the dirt fallen on valves a combination of the above causes I do not remember exactly how I removed the intake box, but I seem to remember that I rotated to right first, I'm not sure. The most common method of EGR delete (if the EGR is not blocked on open) is to remove the hose (arrow 3) and plugging it with a screw.
