  1. 1.4 TDi losing power

    http://www.filedropper.com/documentareturbo I've attached the documentation. Download and unzip. You need Acrobat Reader for read. Try to step-by-step the procedures there.
  2. 1.7 SDI gearbox needed

    The linkage mechanisms, I didn't find the right word
  3. 1.7 SDI gearbox needed

    My car is about 350k km (217k miles), I changed the oil in the box twice and every time I put the vw g50. It still works very well both at -30 degrees celsius and at +40 degrees celsius. Of course I always made sure that the box is full (I swapped the selector seal once) and I periodically greased the selector mechanism.
  4. SDI Hesitation/Judder At Low Revs, Fuel Starvation?

    Yes, but not because it's a problem but because I like more how it works. It has a better torque at low revs. I canceled it only by canceling the EGR vacuum with a screw. The intake flap is still working. Sometimes I canceled the flap, but except a much noise at idle, I did not see any improvement. I really like how it works in this combination: EGR off, 55-degree cetane diesel and 2T oil 100ml/20l diesel
  5. 1.4 TDi losing power

    There are three valves: the N75 that controls the turbine, the N18 that controls the EGR and N239 that command variable intake manifold flap. On VNT (variable nozzle turbo) turbines N18 and N75 are identical in appearance and operation because they operate on a vacuum basis. I think you saw something like that in another VAG. At the bypass turbines (westgate turbine) like the one on your car, N75 is different because it works on a pressure basis. in the first pdf you can see on page 5 how the westgate turbine works . The error 17964 (Charge Pressure Control -Negative Deviation) indicates that the bypass valve has remained open and can not be closed to increase the pressure. I hope the attached documents will help you find the malfunction. VARIABLE_TURBO.pdf N75 Test.pdf Presure unit Test.pdf Supercharger Test.pdf
  6. SDI Hesitation/Judder At Low Revs, Fuel Starvation?

    Yes, canceling the EGR is a good palliative
  7. sdi puff of blue smoke at cold start

    Maybe the timinig. Check Basic settings, group 000, the second field. Put here a printscreen with this group after cold start
  8. If it depends on the travel speed can be from the wheel bearing (if you happen to hear the sound in about the same area you probably accelerate there harder). Usually in this situation the sound only occurs once and does not reappear even if the conditions in which it appeared are reproduced (it isn't a rule, but it can happen ) and the sound disappear at the speed reduction.
  9. SDI Hesitation/Judder At Low Revs, Fuel Starvation?

    Yes, this method is good if you are absolutely sure that egr closes well, otherwise otherwise the blanking plate method is the best way.
  10. SDI Hesitation/Judder At Low Revs, Fuel Starvation?

    I knew we had talked about it but I did not know where Yes trumpets are made of plastic but are made of special plastic that is not attacked by petroleum products. I used brake cleaner, WD40 and a thinner. To clean the soot from the inlet ports on the block I used a sheet-metal spatula After that, to clean the stoot falling on the valves I attached a hose to a vacuum cleaner
  11. SDI Hesitation/Judder At Low Revs, Fuel Starvation?

    I had this problem and the cause can be seen below Obstruction of intake If, when hesitant, the engine exhausts black smoke and the engine noise changes, it is almost certain that this is the cause or the egr does not close well . For testing cancel the EGR by removing the vacuum hose (plug the hose with a screw to prevent vacuum loss) and you can apply the same procedure as the hose that fits into the inlet flap ( operation of this flap is closely related to the functioning EGR ) If the engine's performance improves, you've found the area where you need to fix it .
  12. AUA is a 55 kW engine. The similar 55 kW engines that equipped lupo (with the same manual gearbox 085E code FFR or ETD) are: AHW, AKQ, APE, BBY. AUD isn't a 1.4 16v 55kW motor. It is 1.4 8v 44kW engine. I think the most similar with AUA is APE (the wiring diagrams are identical, the same ECU's Magneti Marelli 4AV). AHW and AKQ are the older generation (with only one oxigen sensor), ECU's and wiring diagrams aren't the same with AUA, and BBY is a newer version with two oxigen sensor but with individual induction coil (the same story like AHW and AKQ from the point of view of wiring diagrams and ECU). The conclusion is that the best fit is an APE engine for a direct replacement.
  13. 1. Try to put the transparent fuel hose (7 in diagram) in a tank with diesel fuel. 2. If it start replace the o-rings of control valve. 3. If it not start check the fuel shut off solenoid and timing.
  14. Diesel engine vacuum pump

    For diesel engines, the vacuum formed in the intake manifold is too small (because a Diesel engine has no throttle butterfies then a vacuum is not created in the inlet manifold in the same way as in a petrol engine) so a separate pump is needed for the brake servo pump and for the control of actuators (EGR, turbo, etc).The PD motors are included it in the tandem pump.
  15. AKU 1.7 block marked 1.9?

    I don't think so. You can not ignore it when installing toothed belt .It is the shaft that drives the oil pump.
