poloSDI

hi, is the polo 9n3 ac same as fabia mk1? i have aircon condensate leaking inside cabin, cant fint the drain, how to fix this? couldnt find the drain https://workshop-manuals.com/volkswagen/polo-mk4/heating_ventilation_air_conditioning/heating_air_conditioning/air_conditioner/plenum_chamber_(heating_and_air_conditioning/climatronic)_-disassemble_and_assemble/

today i notoced it doesnt lose coolant while hot, for example driving uphill it held max level but after cooling down it started to drip

Hi, do you have any idea what might cause this coolant leak? It started yesterday all of a sudden when a coolant light came on, i topped it out with 0.3 liter of coolant, today(20 km later) same thing, here is pic where is it visible below. Any suggestions how could i diagnose the problem myselfs Its kind of a mistery to me how the coolant got to the left circled point on the picture

the clutch pedal on my 1.9 sdi polo 2006 is prettY hard, it has a lot of free play at the beginning and it engages at the very end but it does not slip and works fine besides the mentioned perks. It has at least 150 000km do you think it is time to replace the clutch? Do i maybe need to do something with the flywheel also? There are slight vibrations if i release it quickly at low rpm instead of slowly at higher rpm in which case i avoid the vibrations. Which clutch would you recommend, sachs luk valeo or something else? Do i need to bleed the clutch cylinder? I also need the o ring for the gearbox and the bearing of course? Do i need the new gearbox oil if i replaced it about 70 000km ago? Do you know of any diy guides to replace the clutch?

exactly what i wanted to hear. Finally someone , thank you. Should i ask my mechanic if he used all 3 blocking tools during the job or he tried to use the mark on the flywheel? And if i get it right SETTING UP THE DIESEL PUMP according to vcds TDI TIMING is it guaranteed that everything is ok or it just means that pump is fine tuned but camshaft still can be out of spec by some degree because the mechanic maybe did not lock it up properly?

Im nit trying to make any improvements, i just want it to run properly and within spec as you can see in the graphs from the vcds like it did before timing belt replacement. As i listed above in the guides for timing belt replacement, it is nornal procedure to fine tune the diesel pump after the belt replacement.

Its not the actual pulley that needs to be loosened to tune this as far as i understood from the video and instructions, its just the 3 small bolts for the pump, i dont see what could go wrong here, loosen the pump, make that REALLY small movement in the right direction, fasten it back up correctly, make sure its fine using vcds and thats it.

As it seems from the video i linked, really small movements make a lot of difference, i dont think it is out by a whole tooth, i believe it will be possible to do it with the pump adjustment, after watching the video im even confident doing it myself. I'll let you know how it went, Thanks.

Is it not possible to adjust it via the diesel pump while the belt is on? In this(click) guide from this forum, it is also done after the belt replacement using the "guessing technique", i quote the OP :"When adjusting, loosen the 3 bolts, and turn the diesel pump with the centre bolt, use really really small movements, seriously tiny ones, you may have to do a couple of runs before getting it right, you only need to make sure the timing is within tolerances, I was lucky with my second attempt." Also like it is shown on this video at 2:35, from this guide? Or is it too much out of spec to be able to tune it with pump adjustment? I dont think i will find someone competent here to do it, i will have to teach my mechanic or try it myself. What i dont understand, how does this mechanic work at an authorized Volkswagen Service Center for years, and does not know how to do this properly, and why did he have more luck with the timing the first time he did it, i figured he would be better at it the second time doing it to my car after 7 more years of experience.

Well this is the second timing belt job this mechanic did to my car, and the first pic is 100 000km after the first job he did. The second one is today after the secont timing belt replacement. What can be done at this point? How to correct this now after the "damage has been done"?

This is timing before timing belt replacement And this is timing after the timing belt replacement How bad do you think this is? How do I pursuade my mechanic to fine tune the timing? Obviously he thinks if the engine runs it is fine. I told him to do it before he even started the job, he said he will try, but apparently it is even worse then before, Can i do this by myself? It is done here on this pulley? These 3 bolts should be loosen and then i turn by the cranskaft, or where exactly, and which way and how much would you estimate i should turn based on the graph given up here? What should i keep eye on to make sure i dont do any damage?

Is there any chance to renew pictures?
