Heated seats not working - how to fix them - Audi A4 B8
Hi!
Since I bought the car I observed that the seat heating for the driver was not working fine. The backrest was heating fine, maybe too much, but the lower side of the seat was not heating at all.
In this video you can see me diagnosing the problem and fixing it.
Now the seat is heating very well and I can enjoy the early cold mornings.
If you want to see in detail how to disassemble the seats you can also check this video from a retrofit I did one year ago:

Thanks for taking the time to do this video, my Audi Q7 has the same issues as yours and your video has given me the confidence to take the job on 👍🏻

@istillplaywithcars 2 года назад

Thank you! 🙏 good luck with your fix!

@ajbadenhorst 2 года назад

That is a crazy repair! Well done man. Awesome video. I have an issue with my seat rocking a bit when accelerating or decelerating very fast. Going to have to get my seat out soon to see if I can do anything about it :/

@istillplaywithcars 2 года назад

Thank you!!! 🙏 I’ve seen many people complaining about rocking the backrest, but mine are ok. I can only guess it’s something loose or worn out on the adjusting system. Good luck with the repair!! I hope you can fix it. 😁👍

@ReindeerBork 2 года назад

Thanks for the idea! Helped me bypass the effected area of my seat until I can replace it (:

@istillplaywithcars 2 года назад

I’m glad I could help! 👍😁

foarte fain, big upsi vad ca esti si din Timisoara. Aceeasi problema o am si eu la un A5. O sa ma apuc si eu de treaba curand sper.

Merci! Sa ai spor! Nu e greu, doar ca dureaza. 👍

Thanks for this my A3 drivers seat doesn't work but passenger one does. I think they run off same fuse is that not the case, so cannot be fuse?

@istillplaywithcars 2 года назад

Hi! They run on separate fuses as far as I know. Check that first, it might be a simple fix. 😁

@revengex5163 2 года назад

Good video . Wow 💪👍

@MarkShaw-g6x 6 месяцев назад

Mine just turns off as soon as I turn it on(driver side). Passenger side no issues

@istillplaywithcars 5 месяцев назад

I assume you also get a DTC on HVAC with this behavior. Have you scan it? I’m courios 😁

Just discovered my 2010 a4 q avant drivers seat heat wont work. Wont heat at all, i adjust the setting, light goes on for 10 secs, then off and I check the setting and its at zero. Any ideas? Great video by the way.

@istillplaywithcars 2 года назад

Thank you! 🙏 I would start with checking the fuse. After that I would slide the seat to the back, remove the green connector and measure if you have voltage comming to the seat. If you have voltage, measure the seat resistance. If resistance is also ok (3-5 Ohms) then the thermistor must be nok. Measure resistance of thermistor (the 2x thiner wires in the green connector). The thermistor has the role to shut down the voltage if seat goes too hot, so it seams to be what you have, but it’s best to check step by step. Good luck! I’m here if you have ather questions. 😁👍

@istillplaywithcars 2 года назад

Hi! The fuse should be in the fuse panel, left side of the dashboard. Not sure exactly which fuse number, but you should find explanations on the plastic cover.

@damer950 Год назад

Hi.. I have the same issue.. Teared apart the seat.. Removed the heating element and no breakage found... Did you find out whats the cause of this? Back of the seat works well.. Resistance of the left seat is 2.4 and 4.1...right seat is 5.6 for back and 12.4 for seat..

@istillplaywithcars Год назад

Hi! Also I found no brake point. But assuming that the entry side im the car gets the most wear and tear I’ve shortnend the circuit and excluded that part. After that the resitance dropped to normal values. I suggest you do the same. For sure, that small part of the seat is not getting worm now, but it’s a good compromise. 👍

@damer950 Год назад

@@istillplaywithcars that side part looks very good to me.. Don't know what's the cause of it.. Maybe som cold joint in soldering..

@damer950 Год назад

@@istillplaywithcars what about to solder another wire in the line to decrease resistance?

@istillplaywithcars Год назад

Only if you still keep part of the heating wire in. You need to get rid of the damaged part. But if the damage is in multiple places you can only fix it by replacing the complete bottom wire…

@damer950 Год назад

@@istillplaywithcars I finally found the issue. The wire was partially ripped apart. 1/3 of it was holding together. It was in the same part you bypassed and was pretty hard to find. I had to dig the cable out of the mat and rest of the glue. So the conclusion is that if there is bigger resistance the cable is "half" broken and you need to find where exactly to solder it together.

Salut, am observat de la inceput ca esti roman, dupa am vazut bonul de la Dedeman si o masina de TM. Am si eu problema asta la A4 B7.. crezi ca imi poti da o mana de ajutor? Contra-cost evident :D

@istillplaywithcars 2 года назад

Salut! Da da, sunt roman. 😁 din pacate stau ft prost cu timpul liber, de asta si postez ft rar. Dar cu sfaturi te pot ajuta. 👍

@@istillplaywithcars Cred ca demontarea scaunului nu ar fi o problema.. ceea ce implica functionalitatii si stabilirea cauzei radacina ar fi o problema. La verificarea cu multimetrul, care este valoarea nominala ?

Cred ca am spus in video cat am masurat pe un circuit bun. Nu mai stiu exact valoarea. Trebuie sa ma uit la video 😂
