hi, im dan the guy selling these headlights on
www.dnauto.co.uk, i came back onto forum to help with your questions. please dont report me for spamming and bid on my e-bay items and not pay for them just to leave a negative feedback for spamming forums - thanks
firstly i am selling with 10% discount only until midday today as stated on website, this price is rock bottom - literally break even, reason is to attract buyer through forums so that way reviews can be made which will help me. also delivery is very expensive as they weigh about 16-18kg and are very well packed in individual boxes then put inside wooden crate for safety which adds alot of weight.
i have sold a few of these to france they seem very popular there, you can see my ebay feedback (the french ones) they have reported no problems.
reading back in the thread it seams you have the right idea about coding, without the light will not operate correctly. i dont know what coding is required im not a expert but make sure you have someone with vagcom on hand.
the main benefit of this is that you need to make no modifications to vehicle hardware (wiring etc) hence 'plug and play' claim. and that is where these start becoming alot cheaper than a oem retro-fit. also leds are not DRL's they are side lights but im told can be used as DRL but they not as bright as the DRL lights.
i have close connection to manufacturer and full technical support from them, all their products are very good quality and never had any complaints and very good ebay feedback, they also offer 1 year warranty on faulty components (bulbs, ballast lenses etc) but wont warrant the actual casing if it gets damages etc, but is fully insured on delivery against damage in transit - So Check Them Before You Sign!!
