I really do not know if that was the mistake of the installer who had got the alignment wrong, or it was a defective light. But do enough research and even check out the lights in person if you have access to a car with these installed before buying them.

Also, these are not HIDs. They have halogens in both high and low beams which provide very average output (maybe just marginally better than the stock headlights) and you will have to upgrade to HIDs at least for the low beams.

I am not trying to discourage you. Just speaking from experience from my previous BiXenon retrofit upgrade where I had analyzed all possible solutions available in the market including these.

Having said that, compared to the BiXenon retrofit I did before this, these double-U type headlights are much more reliable because of the dual barrel design, and look fantastic too. So, do some research on the performance part and then go ahead with the install. Wishing you all the very best
Just one more question, trying to activate Coming Home and Leaving feature for the headlights through VCDS, it says that some module is missing for Polo 6R. There is this video on Youtube by a fellow BHPian who has activated this using some "Chinese Automatic Headlight Module". Can some one explain where to get this from as I tried to search on Aliexpress but didn't find anything. Perhaps someone here has already implemented this in his car?

Hi graaja,


Would you be able to tell the tool you used to access screw that holds AC vent in footwell. I have stanley detachable bit set using which I was not able to access this screw. Maybe I need to try again since space below steering wheel is cramped and I did not remove driver seat.

Were you able to check cost of windshield and other parts. If you are replacing windshield then you should get the mirror and other parts from VW itself unless there is significant price difference between them and Aliexpress.

I was able to mount OEM auto dimming mirror and RLS in my car. I got the mirror mount attached by windshield replacement shop. I did this after struggling to find bondtite. I feel glue used by shop (the same one used for fixing windshield) is much stronger and was done for 200INR.

Regards.



Regards.

If they mention problems with these lights, then wont go with them.
It would be good if you can compare the light output of these headlamps with HIDs in them, and one of the cars (any car, even non-VW) with a Xenon Planet HID retrofit, you should be able to see the difference I mentioned in my earlier posts.

P.S. I am not affiliated with Xenon Planet.

Thank you for the kind words vik0728!

You have two options:

1. Retrofit: In retrofitting there are two main risks - the quality of the projectors and the quality of the install. Go for a good brand of projectors like Morimoto to reduce the first risk. You will have to find a good installer to cover the second risk. I have explained some of the mistakes installers make (like improper sealing of headlights, botched up wiring etc) in my other projector retrofit thread. Find out a good installer in your place and get it installed.

2. Replica: Get a replica like the GTi replica which looks same as the OE BiXenons I installed or the dual inverted U type that navdeep.rana has shown. These will have better reliability and lesser installation issues, but the output will not be as good as a proper BiXenon projector. Also, these headlights come with halogen projectors and the output will be very average. I dont know much about who deal with replicas, but you could try Lumens' systems where I got my projectors installed. However, do not go for retrofit with them. There were too many issues as I have explained in my other thread.

If performance is the key parameter, then you have to go with option #1, and for this make sure you get a good installer.

I have documented this in my GT ownership thread. I too had this installed earlier in my car. Check out the below post. This has information on the installation, AliExpress link etc.

I used a regular screw driver set with the Torx bit - the same used for most of the parts like HU, cabin light etc. A wrench may be difficult to operate in that cramped space. Try a straight screw driver with the Torx bit instead.

Also, for small jobs like replacing single wire in the BCM connector etc., there is no need to remove the seat. But for a job like BCM upgrade, it is better to remove the seat.

I might be able to help with this. I had gone to the VW Service Center here in Trivandrum yesterday to check on this (and on some other stuff including the OEM GTi Bi-Xenons ). The information that they gave me is that the windshield for the Vento which is designed for the RLS costs 7K and the RLS module which one needs to buy separately in such cases costs another 11K. This does not include the wiring or the auto-dimming mirror, as per the folks there. Also, they have no idea about how to add all of this to the older cars. (Someone there actually told me that RLS and the other stuff cannot be added to the older Vento / Polo ) So, I guess a windshield alone from VW and all other parts from AliExpress makes the best financial sense.

Thanks VivekCherian for answering this. I totally missed this question in my previous post.

I had contacted VW for the windshield, RLS and mirror. The quote I received was a whopping 53K. 14K for the windshield, 15K for the sensor and 24K for the mirror. If I change the windshield outside, it costs 7K and the RLS and mirror and wiring harness from AliExpress costs $150. So, I get everything at almost 1/3rd the price.

I am going to order the RLS/IRVM online and once I receive this, will get the windshield changed at windshield experts.

Also, for mounting the base to the windshield, you first have to paint the windshield with black primer allowing for an opening for the sensor. I had totally forgotten this as well. That will give good bonding of the base to the windshield. I decided to change the complete windshield so that I don't have to worry about the strength of the adhesive etc.

Below are some pictures of the GT with the BiXenons.

Thatís all folks, I have on the OEM BiXenon upgrade.
Absolutely brilliant upgrade. You are really brave and an expert to embark on such an upgrade. I am sure those inside and outside the forum can really bank on the details mentioned in your thread if they decide to give it a go. As far as I am concerned, I will be happy if I can upgrade my Polo GT's single barrel headlamp to a double barrel one.
Will you be considering a suspension upgrade as well ?

Hi graaja,

You can use following VW OEM primer as well
Part number: D 009 200 02

Another important thing to check with windshield expert would be the mirror mount.

Part number for auto dimming mirror (new Polo/Vento) is 4M0845543

Thank you for the kind words

I have already upgraded the suspensions to KW StreetComfort Coilovers - documented here (Carbon Steel Grey VW Polo GT TSI comes home! EDIT: 10000 km up + OEM bi-xenon headlamps upgrade!).

Thanks a lot for the info. The new windshield actually comes with the base already attached. So, I don't have to worry about sticking the base if I get the complete windshield changed.

Amazing job Ganesh! It truly was a privilege to experience the results of you mods first hand, thank you for that opportunity and answering our million questions. I hope you don't mind me sharing a couple of snaps of your head unit. TPMS and dynamic reversing guidelines in a GT TSI is uber cool and whats even more impressive is you have done all of this by yourself! Kudos!

Thank you so much for the kind words, Deepak

The pleasure was mine. Had an awesome weekend with you and the Bangalore TBHP team. Looking forward to many more such trips
