Hi TheClient, And thanks for Your input. Just as a comment the chain tensioner does not look like in the prev. post, it looks like this in the EA111 1.2 tsi. Its a hydraulic tensioner, but the is a traditionel spring in it as well, to maintain pressure until oil pressure builds up. You dont think this spring could get "tired" as all of us with this type of engine, all at some point suffers from chain rattle at cold startup ?

Hi GamesGoblin, Still haven't found what You are looking for ? BR Mikkel

Im soooo curious... Have'nt you got the tensioner yet ? BR Mikkel

Hi GamesGoblin, Have You been able to try to replace the chain-tensioner only, and see if that helped the rattle at cold startup ? Or it did'nt make a difference ? I would really like to know ? BR Mikkel

That is really interresting! Please kindly update your experience changing the tensioner , and if it makes any difference comparing to how Your engine sounds at startup now. BR Mikkel

Hi Golf-Friend, And thanks for your answer. Is hydraulic tappet noise also a result of the missing oil-pressure in the process of starting the engine ? Is it only on these types of engines (EA111) that the oil pressure takes 2-3 seconds to build up in the engine, or is that a common thing with all engines ? BR Mikkel

Its true that the machine makes a pressure control before it regasses the circuit, but if the "hole" int the system is tiny, then the machine will not detect it. Normally they also fill with a flouresent substance, so as stated above an uv torch could give you an idea where the gas slips out.

Engine temperature has nothing to do with the performance of the climatronic, and the coolness of the air. The compressor is running when the engine is running and the climatronic's A/C function is turned on. If there is enough gas on the system, you should have baltic cold air within 30-60 seconds of starting the engine.

It would be much appreciated if someone with engine knowledge would take a short listen to the video, and the rattle at the startup ? BR Mikkel

Hi All! I have this O2 1.2 tsi 2010 with the EA111 chain engine. The engine did have a complete chain and sprocket renewal in 2017, 80.000 km ago. Im nervous the chain again is elongated, but perhaps Im worried for no reason. I know that this engine is supposed to rattle, until oilpressure builds up, and it does only rattle when cold started (1-2 days since last start), and never rattles when driving. Im aware of the issue with oilfilter seals, and there is not a forgotten seal in my engine. Do you think it sounds un healthy ? At the start on the video it has'nt had a start in 5 days. Even though the chain tensioner is hydraulic, do you think a tensioner can be tired, and become less good over time ? Would it be pointless to try to replace the tensioner only, hoping for less ratlle at startup ? https://drive.google.com/file/d/1ANWCQ9MKvQvRoEFbe6yJnan8IPsE7Lq2/view?usp=sharing

Hi, I also have an engine CBZB 1.2 tsi, and Im nervous about if the chain rattles to much, It only has the strong rattle at sartup for 1-2 seconds, and the it quiets down, but off course Im still able to ar thhe chain rotating. Mine is from sptember 2010, ad the engine control is a simos 10.10, but i simply cant find the value for chain elongation you are writing about. Eg. your chain was 3.4 degrees out. Is it only in newer versions of engine control this is possibe ? I have other values, relating to adaptation between crankshaft and camshaft, and therefore they say something (nut i dont know what) about the length of the chain. Anyone can explain whet these degrees means ?

Hello Everyone, Im really hoping that a technical expert is able to answer this question. For the 1.2 tsi CBZB engine, stretched timing chains is an issue. And the timing between the crankshaft and the camshaft is depending on the chain has the correct length. I was told by skoda that the ecu is monitoring the phase between the 2 shafts, and if its to mych out of phase, it will turn on engine light. BUT im also told that the engine in fact is capable of running pretty normal even if chain has jumped 1 or 2 teeths !!! I have been looking all available measurement points in the engine ecu, and the only thing i find which obvious relates to this, is 270 X_Intake_camshaft_signaledge_position_adapted_value_Edge2 to Edge8. I think it says something about how much the ignition should be adjusted, by comparing the signals from the crank and camshaft. But whst tdoes the values really say ? In general poeple on the net agree that bigger vaues are not good. My chain has just been measured by skoda, and it is NOT too long. I had another car with the same CBZB engine 1.2 tsi, wich were also mesured chain was NOT to long, also attached. Obviously there is difference in how much addaptation needed for the two engines, Im just sooo courious what this adaptation means ? For my engine it says in another measurement that advance timing for cylinder 1 is 8.5 degrees, and the adaptation values is as follows:
