Das ist ja heftig 🎯🎯 https://youtu.be/B-anvmaTvms?t=1282 🎯🎯 Nicht zu fassen https://youtu.be/B-anvmaTvms?t=1755
Great job. Next week I have to replace it in my Benz.
Excellent video, was very usefull when fixing the problem with the Sharan, keep up the good work.
Thanks, mate.
Did the job today and it worked out well thanks to your video…
Hello! Thank you for your video. I need to ask something. After you replace this heater system with a new one, as you did. Does it need to be set up or programmed with a VCDS software? Or is it just a physical replacement with no need of software programming? Waiting for your reply when possible. Thanks
Quick question mate what was the problem leads you to replace the heating element?
Great job but it should be more easier if you empty the tank.
Thank you very much!!!. You saved my time and saved me from possible mistakes!!!
Thanks for your video i did this repair today and it worked great. Keep up the good work!
thanx, you are a sharan repair legend!
thank you very much.
Hi do you no where I can get one from? I’m in west London, I’ve been looking and can’t one used anywhere
Thank you from Germany. This is Super.
Greetings from ROMANIA. Thx for the great video. It helps a lot
Thank you a lot👍🏼
Thanks a LOT, this video is very well done with clear explanations. Saved me a lot of time. Good job!
I have many questions can you message me I have a 2012 Passat
Really detailed video, I am taking this to my mechanic, hopefully it will save me some money. I have the "PB205B Reductant tank temperature sensor signal faulty" error on my 2.0 Sharan. But the thing is, it is not constant. I first received the error last winter (the mechanic used the computer to delete it), then I received the error again last Friday. I managed to find online someone that actually replaced the temperature sensor DIY https://www.myturbodiesel.com/threads/def-p205b-temp-sensor-diy-fix.28155/. Du you think this is possible? or it will last? I am asking because its a huge difference between 300euro and 10 euro 🙂
It was painful watching you with the scissors. Please, buy a dikes! (And a strap wrench.)
I've got a P202A error also, however my adblue fluid level was low too. The bottle and spanner have been flashing so I topped it up fully however the spanner and bottle is still flashing and CEL is on. Are these systems linked?? Are you anywhere near Manchester?? Thanks
interesting lesson. i have error code P205B and heard this is the problem too. So learning is not necessary after the work has been carried out?

Hello, I have Seat Alhambra 2014 2.0 TDI 103kw, and PC says codes P203B and P205B. Do you think that by changing heating system it will erase both errors?
I think that Sharan and Alhambra are almost the same cars 🙂 thanks for answer and for great instructional video.
Hi thanks for your video.Where you are based.And garage contact no please.
I have a 2015 Sharan and the pump has just gone. Does anyone know if the later tank with the pump at the bottom can be substituted? Is the wiring the same? Thanks
Just changed mine too. Thanks to your video with no problems. Thx
