Audi TT Mk1 - Fixing the roof close sensor on a cabriolet
Вставка
- Опубліковано 1 жов 2024
- I recently replaced the roof on my Audi TT Cabriolet. When the roof is closed the roof warning light stays on indicating the roof is not closed. So I investigated how the roof knows it is closed and it is down to a sensor switch in the passenger side of the top edge of the windscreen frame where it meets the hood. I need to know how to fix the roof close sensor.
A quick investigation lead me to the answer. Stick a small section of plastic from a credit card to the switch to make it thicker so it can make contact with the car and close the relay loop.
Works perfectly.
So if you are having issues with roof close sensor or you want to fix the soft top on Audi TT, this may be the guide you need. This may help you fixing Audi TT Roof.
Please do leave me feedback on this video and any other jobs you would like me to do that could help you out.
If I am ever caught on the space shuttle while experiencing a catastrophic "ALL SYSTEMS" failure, please patch my communications to Andy so I can sort out the problem, access the problem, and apply the solution with my Swiss Army Knife! You ARE an evil genius!
Thanks so much! Your support is appreciated!
thanksso much
Thank you soooo much!!! I just had this problem and solved it in a couple of minutes with an old credit card!!
I’m glad to help buddy! 👍
Just Adjust the hook on the convertible top
Yes you could do that but that is definitely more involved. A quick sliver of plastic will definitely get you out of trouble!
Hi Andy,
What kind of glue did u use to make sure the piece of credit card will stay in place?
Hi Jo. I used some General purpose Evostik. That way if I needed to remove at some point, I could. Thanks for your comment.
Hi done you have any clues on why my roof won't come back up? The roof comes down no issues, windows drop a small amount as normal... but when I hit the switch to come up the windows drop a small amount and go up again... which then doesn't alow the roof to start it's journey back up to the close position.
Totally baffled with this
Thanks in advance
Chris
Hi Chris. Check both sides of the roof, just about where the roof hinges up to make sure the 2 struts are attached. They are like the ones that hold the boot open and clip over a ball socket on the hood and are secured by a metal clip. They have a habit of popping off.
Thanks for the reply.
Everything looks fine. I have also done a window reset but not helped.
The window just won't stay in the position (about 1 inch down) while I hold the button to bring the roof up. So the roof just won't start to lift.
Fingers crossed you have an idea.
Thanks
So what about the window no longer dropping? I pit a piece of plastic on mine, solved that issue of the light but now windows don't drop. How is that solved?
Wow wow wow Andy!!!
Good on you! I make a request on the hood switch (or roof as I call it in the states) Then you go and make a video on it. That is a fabulous response!!!!
Can’t wait to go try it on my car and I’ll let you know how it goes
Thank you very much! Tom S from Tacoma Washington
You ask…I delivered! I forgot the “hood” in the USA is our “bonnet”. The “hood” in UK is also the roof or “rag top”! I hope it helps buddy! Let me know how you get on! 👍
Very helpful my friend
Thank you for your kind words Bjorn! 👍
Hello Andy super ta chaîne 😊
J'ai démonté une capote avec l'armature complet pour pouvoir changer les tuyaux d'évacuation que j'ai remplacé avec un tuyau de machine a laver.
Mais j'ai un soucis quand j'ai remis la capote j'ai un espace entre la toile et la carrosserie arrière 😢
merci pour vos gentils mots sur ma chaîne. je recommanderais de retirer le capot et de réessayer. on dirait que quelque chose n'est pas aligné lorsque vous l'avez remonté. j'espère que vous le résoudrez.
@@andycharger merci beaucoup pour votre réactivité 👍😁
Thanks Andy for taking time and articulating the issue and the solution, I happen to have a self tapping screw Spring clip which fitted perfectly over the switch actuator paddle thus increasing it's thickness. Job done.
Great work Derek! Always good to hear of alternative ways to crack the problem. Thanks for your kind words!
Are they 2 types of micro switches? Mine has a plunger in the round hole
After watching the blinking roof open light on the dash for 1,800 miles on the maiden voyage, two weeks ago, this is a welcome salve. Thanks Andy
Very helpful thank you! Just had this problem this summer.
Hi Andy my roof won’t go down with the switch, I can hear a click but no movement any ideas mate.
Hi Paul. Any sound like the pump/motor running? It’s common for the CCM to faul on them if water has ingressed. If the CCM is ok, a fuse or the actual pump could have failed. The struts that raise and lower the roof have a habit of popping off too so check those. 👍
@@andycharger it goes up ok Andy with the switch engaged is there a separate fuse for it going up,what’s the easiest way to get at the cam because I looked at we’re it is and it’s a bugger to get at. Thanks for reply mate.
Ccm I meant I hear a clicking noise when I engage the switch for bringing it down it goes up ok mate
your channel is a blessing for the tt owners. Can you make a video about how to fix the wind deflector? i know it's a very common issue. For example , when i bought the car only the one side was going up and down and eventually it stopped moving at all. I only here a clicking noise when i activate the switch
Hi Eliza and thanks for your comment! I would imagine one of the motors that drive the mechanism for the deflector has failed. It could also be the fuse/relay has failed but I would expect that they are both on the same fuse/relay. Therefore it is more likely to be the motor. I will investigate for you and see if i can do a video. Thanks again and keep on watching the channel!
Great video, just what I needed and worked a treat. Thanks mate ❤
Ha ha! The old credit card trick!
Does the light stay on the dash when the roof is open as mine does not
When the roof is all the way retracted, there must be a sensor that detects it down. The light goes out at that point. Anywhere between fully open or fully closed activates the light 👍
@@andycharger thanks mate
another option (the one I use): do the adjustment on the oposite side by placing a very thin piece of plastic or metal tube over the bar that the hook goes around. This will pull the whole roof over very slightly (to where it should be perhaps) and close the finicky switch on the drivers side.
That is also a very good solution Tracy. It’s all about getting that hook over far enough to push that switch, one way or another! 👌 thanks for the extra tip 👍
Just to clarify my roof goes up ok cheers
Works thanks Andy for the tip
Got your response, thanks Andy!
Went to an "Audi Specialist" with the problem who quoted me £100 + VAT to repair it. Thought I'd UA-cam it first. Thank you Andy!
Great news! I’m glad it saved you some money! 👍
Thank you! Used a piece of thick 3M double sided tape - left on the contact side plastic liner - and it worked like a gem!!
Wasted $132 to be told that it cannot be fixed. Audi dealers clueless when asked about this occurring.
I’m glad it helped you buddy! 👍
Absolutely brilliant and extremely clear. I have this issue on my identical TT. I have been seeing an enormous bill looming. Reading about it on various forums has just confused me. Thanks for the extreme clarity here so that I can see exactly what needs addressing. Liked and subscribed.
Hi Graham. Than you for your kind words and subscribing. I like to think my straightforward and simple videos help out people like myself. Willing to give it a go but not mechanics! Let’s keep these wonderful cars in the road! 👍
EXACTLY what I needed. Brilliant video. Top stuff
My pleasure buddy! I’m glad it helped! Don’t forget to check out some of the other “how to” guides on the channel!
IT WORKS!! Awesome! I cut a small piece of a body filler plastic blade that is very slick and slightly tappered 1/2" X 5/8" roughly (12mm X 16mm), cleaned metal microswitch part with alcohol, used 2 part epoxy and waited over night to try it. To my delight...light went off with roof closed. Great tips Andy and loved the illustration too.
Thanks Sean. I was skeptical also but it does work! It just thickens the mechanism enough to make contact. I’m glad it sorted your problem!
Thanks a lot Andy, piece of plastic solved issue I was struggling since months!
Great to hear it’s fixed buddy!
Thank you so much! The Credit card hack worked wonderfully! I glued 4 small pieces together, then wrapped it in electrical tape so that it blends in with the car and then glued it to the sensor. Cant tell at all and more importantly the sensor is doing its job now!
Great work Dar! Im glad you found it useful. Dont forget to check out some of my other useful maintenance hacks too!
Andy - OMG - I did the credit card trick and it worked beyond great!!! major major thank you!
So glad it worked for you buddy! That’s what the channel is here for! You can buy me a beer sometime 😉👍
You have saved the day. The credit card worked perfectly!!👏🏻👏🏻
Glad I could help! Let me know if you need any other fixes!
Thank you, I fixed mine due to your generous time & video. God bless.
My pleasure! I’m glad it helped you out 👍
Brilliant - this is exactly what was happening to mine. Also why the windows don't go up the last inch or so after the roof has gone down.
Hi Simon. If the windows are not going up when the roof is down, do you get the flashing "roof down" light on the dash? It would suggest there is something stopping the roof going all the way down or the sensor that detects its all the way down is reading incorrectly for some reason. Worth checking. I am glad my video helped you out buddy!
Andy I too want a video showing how to fix my wind deflector. Cant figure out how to get it out and fear I am going to bust the plastic. Only goes partially up...Help please!
Ok my man I will take a look!
@@andycharger lift it up and remove the plug from the engine, l did the same with mine and all the time is up
Brilliant fix, saved me hours of trying to fix.
Great to know John! I am glad it helped. I have a new video dropping at 6:30pm this evening featuring top 10 tips and tricks to owning a TT Roadster. It has lots of info on compartments, roof fixes, etc to help out other owners who might not know some of these features. Let me know what you think! Thanks for watching!
Great ..Thank you. Saved me time and £30 on a replacement sensor.
I’m glad it helped and saved you some money! Winner winner! 👍
@@andycharger I have 2 of these pain in the butt but also I won't give up toys. Just listed the 150 on Ebay. 225 needs a new roof ,it's the new project before the summer. The old flame will hit the road again. That I will never sell alongside my 330ci M Sport and a 1990 Celica GTI..
Again a good productive Video. Well done Andy , despite I don't own a convertible!!
Cheers Ben! I may be acquiring a hard top as well in next couple of weeks! Keep your eyes peeled for that video! That is going to be a reclamation project and a half!
@@andycharger Brilliant
Always looking forward for ur Videos. Ta
Thanks mate! This is the 1st mention of this new project that I’m hoping will turn up over the next couple of weeks. The best bit is, I only know it’s a hard top. It’s going to be a total surprise. It might be a 180 or it might be a QS! Who knows! I don’t even know what colour it is yet. All I know is it has been sitting unused for a few years in someone’s garden. Hoping for a barn find! 🤞🤞🤞
@@andycharger Will be interesting Andy!! All best pal
Mine does the opposite, the light flashes continuously when the roof is open and the wind deflector no longer goes up. It looks like the previous owner has already modified the micro switch
That sounds like a short somewhere in the system. Have you checked the fuses and relays?
Check Sensor F171
I have this exact same problem. Would love to hear if you've been able to solve it and, if so, how. Thanks!!
Great video, Andy! Thanks so much for posting these. I'm having the opposite issue. The Folding Top warning light stays on even after the top is all the way down. I take it this is a fault in switch F171 but I'm not sure how to access/clean that switch. Any thoughts?
Hi Noah. Thanks for your supportive feedback! That sounds like something is not triggering in the "down" position. I will take a look at the removed hood and see if i can spot a sensor of any sort that might register its down.
@@andycharger Thanks! I'm pretty sure it's Sensor F171 that's not registering the nec 9V when the top is down but I'm not sure how to physically access it. Would love your advice. Cheers, N
@@andycharger Howdy! Any news? I'm really struggling with this and my mechanic wants a lot of money just to diagnose the issue. Hoping you can help me figure out how to access Switch F171 to see if it maybe just needs a cleaning. Cheers! N
@@osainista sorry for my late reply. If you drop me an email I will take some pictures to show where I think the problem microswitches may be. andy_charger@hotmail.com
Brilliant, thanks!
I’m glad it helped you. It’s crazy how a little piece of plastic can fix it!
Another top solution...well done mate.
Thank you very much Gary! Much appreciated!
Hi I have just got into my MK1 2001 plate soft top and the switches are not opening the roof for me not side where the fuse is for this I have checked the Haynes manual trying to fix it myself hope you can help
@@mariamshai2530 have you checked the various relays and fuses that power it? I think they are i the drivers footwell
