Audi VW Skoda and Seat Warm starting problem

hey guys this is a quick video no no fix here so this is a quick video about the Audi a3 2-liter diesel the engine bkd I have an issue so when the car is cold he starts very well but when he's hot he struggle to start so I found something interesting but I know my battery he's not strong because all the time when I connect the scanner the obd 11 he says orange is not strong enough well I got the car already one move because this car was broken so I fix and now I'm using for work so one thing I found is when I start the ignition the temperature is down like you can see and now I will show you something interesting so he maybe can be different cases for other people but I believe my case will be a battery or maybe as well the starter but I will start change the battery first cuz I see something you're funny so if you see here the RPM yeah so when the engine is cold let's see if I can film you see you can see straight away like 427 rpm when he's cranking okay when is cold the thing is when is hot he cranks oh only 187 so he's no enough he should crank at least 280 or 240 nothing 280 is for for the injectors fire so this explains is my battery's is no good ok so what I will do I will go now we rock our parts and then I will make a clip when the car will be very hot and you will see the speed 1 is cranking and you will see it's very low ok so stay tuned hello guys again so I'm inside the garage I pick up already damn the battery so we'll show you what happens so now the temperature sorry the temperature T's enemy at all that say so now we'll go through the scanner just waiting and you will try crank and see the speed only one thing I see is because that is 90 degrees but here says is 80 degrees so I don't think this is correct but okay we will ignore this for now so now I will crank the car and ever look the RPM see he starts 74 then you go 212 under knee starts I believe this is well my battery is not it's not good anyway because I know that huh but we will try put a new battery on and see what will happen if will improve or not so for change the battery is very quick so I will do now the temperature is still hot and then we will try after that okay but that sensor is little bit weird this is a t1 it should be 90 like it is 90 even now he gonna buy up more so let's login again that that's not on sounds right to me so let's see again what is the temperature now so now he's 82 so the temperature I believe he's far off maybe 10 degrees I don't know if it is causing the problem to the car but we will have a look so we will change the battery and we will come back in a minute right so now I think it's of videos in YouTube so you take this cover off first well actually this one the cover off first then this one on the side so now we will disconnect this too so now is 13 you will be good see so let's try don't take all the boat out because otherwise will be a nightmare to fit and see if he comes off I think I will try remove the holes you can get the pliers oh if you go to magnet here this means it's good take the caps off now we put the plate again back then I will be tricky because I'm magnet now we let this go not very it will be better if we removed their intake you know I mean this will give you more access so if you want a job easier see you away how many'd really feel this because you know right so the magnet you can try to set the boat so don't be mad anyway right let's start the car and see how it starts just wait a minute because I leave the tripod in the top of the engine right so that's why again so start ignition the ESP light and the stereo light will be on because we disconnect a battery but after you start driving he will go off okay well looks like is not the problem from the battery like you can see is still exactly the same issue so let's kill the car try again No my friends this is not a battery okay so now what I just don't know if the camera for some reason I don't know why so let's now take this Canon again so for you see number one battery he's not a battery so he's still exactly the same issue okay so the battery know will help you in this problem maybe in some cases can but see so now we say seventy six C and my needle is just a little bit down so that's not right it's still 208 so to me it can be two possible things number one the sensor is not reading correct for some reason but I will probably change the sensor okay some people say is the issue because if you see the needle always it's close to ninety but it's a 77 I'm not happy that and number two probably the starter cuz that people say when they start to get soft he gets tired so probably they start a problem so I have to try now the starter so I'm not happy about the battery so what I think what I will do is take the battery out and take back and just replace for a starter I don't think is the temperature sensor because if you see the crank speed is well below now I did reset this kinda so I didn't pick up okay guys so that's the thing it's not the battery so we have to see what caused this problem even now the temperature sensor say minus six that can't be righted a minus six well minus X because this can erase its losses let's try again but I don't know where you get this so when you turn off the car he gets minus six oh that's weird okay [Music] 79 degrees is almost 90 so I believe the sunset is is not good either right so the next step will be probably to change the sensor on the starter because I don't think the sensor we cause the engine to turn slower the starter you will so okay we will come back to the starter then hello guys again so before I go aero car parts pick up a start and I just try something else so I put all the battery back and I disconnect the temperature sensor and watch this starts starts very good that's where dinner the car is hot but the sensors disconnected that's why you can see the reading but [Music] okay so now we will connect the sensor back just after the sensor well I have to take these pipes in here for that access because otherwise he's a tight fit in there and the sense is somewhere in there and you just have to follow the thermostat playing so I connect know that the sensors I just will put these pipes here here so now we start again it looks like another temperature even is in zero that's not right is it should go up okay let's try again now he goes where he should be to be honest I believe this is really the sensor not really the battery or the starter so what I have to do is just go where your car parts pick up a new sensor put the sensor in and we will see the difference okay so I will go a car parts exchange and give the battery back and say well was a mistake it wasn't a battery so they should be alright if that and then get the sensor and see how he goes okay so come back in a minute hey guys no bigs here so this is about the LD the warm start problem so so far I will tell me what I change out so we tried the battery it didn't work so with this couldn't we disconnect the temperature sensors and the engine actually starts alright but I believe because it give more power because it's cold II think he's called I don't know but okay so I was faking the senses is faulty so is two of those I don't know what another one is well two of those I put new exactly the same problem so warm start it takes ages to start five seconds eight seconds sometimes then I change the crankshaft sensor well it looks like somebody changed this one already because it's not original from Audi but guess what after I change nothing happens still exactly the same the only difference I notice is when you crank the engine it not is not juddering you know it's not shaking is it's cranking but I don't start it takes like five seconds to fire up so this was a pain to change because I have to take off all the fuel or the fuel no the all your housing yeah and this is a nightmare like you can see is lots of bits in there so everything this have to come off very sorry to not film how to take this off but you know this is very easy soon you start taking the EGR and the flop motor out you can see some bolts to take it out and remove them the old filter housing I just recommend you have new washers and new gasket to go to the block okay and then it's a quite trick position for take this out if like eleven allen key or the bolt is missing from you now and when you put in you just have to make sure you engage this pin in a housing from the gearbox and then in here you have missed this notch so you should line up in engine or in the gearbox I think no sorry in the engine forgot what I said there's no cheese in the engine in the bottom you can see if you put a mirror there's no much space for you look inside and then this not you have to go in a hole as well so you have to tight if the fingers and then just if the olive oil the olive oil the allen key tight the boat and the eventually the fries go in and the saucer stays securely in place now so it's not this sensor yeah another thing I was doing so I will show you later when tomorrow we'll put the starter is something to do about the engine be behind our head but I will the next video I will show you what I did as well so my engine was like - 2:45 so I will put the pictures in here in a video there before and after and something they call like the tone the torsion value I think is how they call I'm not sure perfect is how we call and mine was a little bit hard okay so I just pushed forward little day and now is zero so I was faking this is the problem for starting the world start because some people complain no the engine the timing was will be out so I adjust and then the car was fine but in my case is zero is still exactly the same no change whatsoever the only thing I have to see now is the miles per gallon if will increase or decrease because some people they said they put it right on zero and all close to zero and then miles per gallon was worse so my net moment is 5855 so that's quite good for this car and they aged but I didn't have no chance to go far and see how the miles per gallon is another problem I got now so today because the warm starts some people say the starter so the starter gets tired yeah when he's hot and any he cranks slower so I take the old one to the shop now I put the battery for charging because I was trying to start guess what so this is the new starter and guess what the solenoid is that so when you crank the engine you can hear spinning but the solenoid engaged this this here to the flywheel so you just can hear the motor the motor screaming so guess what this is me what I've become today from Aero car parts and his dad already the thing I saw in this the box was open already I believe somebody bought this was broken they take back and then now they sell to me and they keep my good one it was working well not in a warm starts he was a little bit slow but he was working so now the car stay in the garage so I can do nothing now I just have to wait okay so that's the thing so far so number one we tried the battery like you see he didn't work so number two we check the sensors we disconnect the sensors II did start alright but I think maybe something in AC you think the car is cold and then he gives more diesel to start and then that's why the car start straight away so that's the obvious explanation number three I did change the crankshaft sensor and looks like it's still exactly the same because when I was cranking the car you see in a video that the cranking was showing 74 RPM sometimes when this is hot they start breaking and don't read very well in every nose and seat row and this happen a lot okay I know this is all D but it could be the same case sometimes yeah so we tried this one number three so so this says as it was to to change and he's still exactly the same the only thing I still have is when the car is in temperature 90 degrees it still shows this kind of 83 I don't know why so I think I don't will pay attention to that the only thing I found is when you drive like for one hour or something that's it / - never go up he steals in the middle but the bottom holes is still cold well I don't know if this is normal not is the first time I have a TDI but some people say it's normal some people say it's not so I just will leave this alone so we will start now we I tried the number four so I try put the engine on time so the torsion torsion value sorry about that but that word is a little bit weird for his day it was a little bit out like - 245 I will put the pictures in the end of the video so you can see before and after and then I adjust it take me five attempts to put in zero and then he's still exactly the same so for when is one star they take longer to start so it wasn't that okay so the final thing we will do now is the starter so when I hit the starter if nothing will change so we just have to to leave the car alone so I believe this will be something to do if the injectors or something else in a computer I don't know this is what I will try I notice you know old start when I turn the wheel is what it was will be rough so we will try the new start and let's see how it goes okay so when I will get a new starter I will make a new clip and then we will see if they solve the problem if the starter will be the problem of the this engines so the first thing you should do is check the battery if is good if not change the starter and it should be alright so stay tuned for see the results hello guys fix yeah right so I change the start I got the start on you in the car already and like I can show you looks like the starters of the problem so if I start the ignition you can see the temperature is in the middle and now watch this he looks like he started better he he sounds like he's still struggling there but Evelyn yeah he looks like he's better you don't take ages to crank like before so yes guys so you have a problem if your cards starting the Audi a3 or maybe golf will be the same so the first thing to do is check the battery and check the star if the battery is okay check the starter so the starter maybe start dying and he turns to low and he's hot so I change lots of things like you see before even the dermal start I change because the temperature think that the bottom holes be cold so now he looks like he's still the same so just go first for the battery and then they start okay so I hope this helps thank you very much for watching so if you liked the video put a thumbs up if you don't like the video you just pour thumbs down and then let me know yeah why you don't like the video so the next time I can improve okay thank you very much bye bye
