Audi VW Skoda and Seat Warm starting problem

- made some diagnostics about this issue happens on BKD engines fitted on Skoda, Vw,Seat and Audi. did change many parts but looks like new start did help a lot on warm starts. of course this can be different in some cases but mine was the starter. about the torsion value dont worry about it. didn't help at all and for who dont know about this change the torsion value dont do it, u can cause severe engine damage. enjoy.
I had exactly same problem VW Golf MK5 BKD 140bhp- engine would not turn over when warm - changed fuel temp sensor - did not work, changed starter motor - did not work - Changed the Camshaft position sensor (Difficult job as bolt is hidden). Car works perfect now
I currently have the same issue after supercharging my bmw m6. I've changed the coolant temp sensor + crankshaft sensor + battery, problem still exists. I will now look at changing the starter motor. Thanks for the vide, loved it!
Any update on what was the issue
@@umarj3461 Yeah I replaced my fuel tank vent valves under my intake plenum and fixed the issue.
Ok glad it's sorted. I got a q7 which cranks only when cold not won't crank when warm
@@umarj3461 Try replacing the fuel tank vent valves. You never know.
Hello, I was in authorized service center today. My issue was grounding cable on 2007 Q7. Battery, starter and other things were already replaced in my car by the previous owner, but the issue remained. The fix was cheap and effective.
Which grounding cable was the issue?
Now your video deserves a top rank because you were just trying your level best to solve the problem and i salute you. I am gonna look into it. I have 54 plate 1.9tdi A3 and Rac said its the glow plugs cylinder 1 so today i changed all glow plugs and did full servicing but problem still there. After watching your video i am quite confident 👌👍 will get the starter motor and see from there. I will inform you 🙏
You were right my car was fixed after changing the starter motor 👍Thanks a Million
I had an A3 2.0 TDI with the same problem and the changed the starter motor and the battery and it didn't make a difference. I did a trick to make it sort of start faster from hot by spinning the starter motor once then doing it again and it would fire right up. I later found out that the ECU didn't inject fuel into the cylinders from hot like it did from cold so had the ECU remapped to inject fuel into the cylinders when hot and it solved it. I heard many horrors about the BKD engine but i didn't have a single problem with mine.
Exactly the solution an expert told me. I also have an A3 2.0 TDi 140 BKD.
@@L0p3s I surprised an Audi specialist when i did that.
it's fuel related problem, the solution is to increase the strating injected fuel quantity using vcds. hope this helps ;)
I have the VCDS but don’t know how to access the feature you’re talking about. Could you help please?
@@Righteouness you will found in this video the solution for both edc16 and edc15 ecus hope this helps ua-cam.com/video/C2VVLEXaV4Y/v-deo.html
@@ayoub7755 thank you!
@@ayoub7755 channel 1 does not exist / Error?
@@Righteounesswhat is the Make and model year of your car ?
2:30 temp gauge shows 90°C when real temperature is 75-110°C, that's why diagnostics shows other temp (diagnostics temp is the real temp read by coolant sensor)
Very informative video! Thumbs up man
I ve been suffering from this problem for more than 2 months now.&it's driving me crazy. . As u did -and before watching your video- I changed the battery and the sensor. .but still doesn't start when hot. I guess I will check with the starter. .
Thanks
Updates?
Did u fix your car
Excellent video, detailed and informative. Now I am sure my car has starter issue.
I have the same problem with my audi a3 2.0 tdi Thanks to your video I disconnected the temp sensor and the car startet first turn. Now I am going to replace the sensor to see if that was the problem. Thanks again
Very welcome 😉
Did yours have 2 coolant temp sensors? If so which did you unplug?
And did the new sensors fix it?
Sounds to me that you should check / replace the ground cable connecting the motor and the chassis. Bad connection in that cable will make the starter weak and affect the battery charge. Often you can measure the voltage plus on the generator and ground some where with a good connection on the engine (be careful , rotating parts) and compare that to what you measure on the battery plus and minus. It should be pretty much the same voltage. If not then you probably have a bad ground connection from the engine block to the chassis.
Did check them. All fine. This is a comum issue with these cars.
Granda tuga. Tenho o mesmo problema no meu seat leon 2007 Tdi 140cv. Vou mudar a bateria 1st
Same issue with a VW Golf 5 1.9TDI, took off the starter and gave it for repair. Hopefully they will fix it today, so that I may put it on my car after work and see if the issue has been fixed.
Is it ok now?
@@abdulsalamarakkal6724 Yep, no issues since then. Costed about $30. Keep in mind that it might also be the timing belt, that needs changing or at least adjustment :) .
great vid nuno thankyou for this its helped me diagnose much easier. 1 question did you have to clear the engine management light or did it go out on its own?
U need to reset it, sometimes it does stuck the light on. Quick reset should solve the problem.
I have the same problem with my Peugeot 308 diesel. It's not the battery and I've been to various garages and nobody has mentioned starter motor so that will be the next thing I'll try.
New starter motor will help alot. 😉
Very informative, thank you so much
I have the opposite problem, when its starting from cold it takes a huge effort for the starter to start the car but as long as I have turned it on it will start just fine. Injectors maybe? I don't have any fault codes.. Though I did look around in live data and saw the injection start from cold was 0.6° v.OT when it should be between 4° v.OT to 2° n.OT
Thanks for the video.
Mine use to do this now it's just got worse it is taking me two attempts to try and start it but this video helped me a lot
My update now is that it won’t start at all... so you are saying it’s the starter motor
Good video pal 👌
Thanks mate
Hi, could you please tell me what was hot crank speed on new starter?
Top video thanks 💪💪💪
That’s something called hot start issue I just remap that out and it fixes it 100% of the time on the bkd engine
Also if it was the crank position sensor it would crank a lot longer than that
Hi. Thanks for your comment. Could you please drop the link showing how we could remap to solve this issue
Malik Bebane this is something you will need a kess v2 for

@@blackburnuk thank you. Do you think I could remap these values with VCDS ?
thank you ,
Faulty Ambient temp sensor also gives this problem by tripping the ecu with fault temps
I have the starting problem at cold and warm both.. and the engine kicks very hard before starting, any suggestions please? I have BKD engine and hope that's not the camshaft get's broken
hi, same issue, did you figure out what it was? :)
@@mlvyy change the starter motor and give result!
This problem needs to be fixed by ECU. You need to search for hot start fix.
Thanks 🙏
is that normal having such difference in the coolant temp readings, instrument cluster vs scanner tool? the sensor on my car was replaced to a new one and i've got same engine and never seen scanner readings exceed 84C whilst instrument cluster shows 90C.
Hi folks,has anyone fixed this problem with a new starter?i am having same issue,replaced fuel pump,coolant temp sensor,crank shaft sensor,checked battery,now thinking of changing starter!!! exactly same problem with hot start otherwise cold the car will start first turn,i contacted software mapping company who said it is not a software problem as it is 2009 and there is issues which can be solved with hot start before 2007.
Hi. I have the same issue. What if i put a new pair of brushes inside the original starter instead of buying a new one? Do you think this will work?
If u replace the brushes and clean all the starter very well it should help. Brushes is cheap so give a try. I did buy new for purposes of the video. 😉
@@axores20 Thank you for the answer, i will change them probably next week, and came up with an update.
@@vlad8985 what is it
Is yours a common rail or PD engine? I have a 2.0 TDI CR170 with the same issue, it's intermittent tho and doesn't always do it when warm! Normally it starts fine from cold. Not sure what to try first!
Hi. This one its a pd engine. Is yours a pd?
Did you manage to fix it
It said - 6 because you disconnected battery
You will change this battery soon crap lion dont use your car for 4 days and its death 👍good kuck with euro crap parts 😁 lovely video
Thx man
VAG hot start problem... for 75$ you can solved problem via computer
Yeah thats true. But starter was cranking slow so new starter helps to me. Just a guide video to solve slow crank. Like u saw somebody change the crank sensor because did have the same problem. But via computer u can change the values of fuel on start up.
Cao. Kako ?
Can u please help iam having the same problem
hey pal, i have question, i drive audi a3 2.0 bdk, my problem is when its sitting at parking for 1 day, i mean when its cold, its actually hard start, its like yours on warm starting. Battery is good, alternator i think its good too, soo what can be next problem. i also mean it have chiptunning. I hope u help

Hi
The problem is not solved 100%
In the future you will have the same issue, if you take a look to the board, the lights go OFF when you want to start
I have the same problem and I dont know how to fixit
I tried new battery, change the rpm in the soft, change starter.
If somebody know the solution pls leave it in a comment
Hi. Thanks for the comment. Well this did help lots of people. So far the car goes great and starts fine. Almost one year and still starts like on the video. Very sorry didn't help u out. But if i will find new solution i will post it 😉
The solution comes from the engine ecu.
The Injection quantities in this engines WHEN they are hot it's too little.
The solutions is a simply remap. Trust me, it will solve 99.9% of hot start problems.
Fixing the battery or starter will logically improve a little because the cranking it's a bitter faster. But will not solve!
Simply Changing the ecu map for a automatic gearbox engine map will solve this because de auto gearboxs models have a little more IQ in the main ecu map at hot temperatures.
As will said. The hot start map isn’t good enough you need to copy the cold map onto the hot one
@@willytavares2893 hello mate I have the same issue do you no where I can get it done from, I am in Coventry
hi
so how did you solve the problem?
thank you
Yes car is still starting fine after new starter. I know you owns the car now and he had no complaints my friend. New starter will help. Remapping will help too 😊
@@axores20 ok, but specifically what did you do? did you change the starter motor? a sensor? what specifically??? give me the solution you used to the problem 🙂
because I'm Italian, and youtube (google) translates really badly and you don't understand anything!!!
that's why I only ask you for the definitive solution which then solved the problem thanksssss
Thank you for the video. I have the exactly the same issue in my golf. Nothing has changed even after replacing the starter. Do you think there is another reason that can cause the problem ?
see my comment a little upper . It will solve your problem
@@willytavares2893 thank you. Actually as I have only Vcds software for the moment. Im wondering whether its possible to update injection data using vcds

My golf 5 1.9 tdi has the same problem... But it's even worse because it shuts down by itself while driving and then it's very hard to start it again... Already changed the cam sensor.... Going to change the crank sensor also....anyone has a real solution?
Was it fuel pump related
@@umarj3461 yes indeed it was. Changed the fuel pump and now it's working fine. Still have to change the starter because it's very rough when the engine is hot.
@@brunoduarte7532 I’ve had the same problem with mine too. in the end it was the tandem fuel injection pump that sits on the right hand side of the engine...now as you describe, starting the engine is very rough, especially when the engine is hot. Can I ask you: What made you sure about getting the starter motor replaced as I suspect this too? Also my fuel economy is terrible like 28mpg - was usually 45mpg
Hello,what was the problem?
The starter motor did help and fix the issue. But also a remap could help to start better.
No point wasting money on hot start map just buy new starter
My friend, you have fitted a poor quality battery.
Is completely the other way for me lol
Scan the damn thing, stop throwing money away and time. You keep saying "The first thing you do is" No Scan it and find a temp sensor fault in the wiring !!!!
No any codes related to this problem. Temperature sensors was changed to check if the starting problem be solved. Sensors is cheap. I did this to make the video only. Then people saves money and get to the point. Another fix is remapping and change the values of fuel on start up. But some people dont want messing around with ecu.
