Hi all.

Has anyone heard of this problem before. When I accelerate my front right headlight starts to flicker and I get a warning please check lights but then the light jumps back into life. This only happens when I accelerate or brake hard. can anyone help

I am having problem at the dealership my rear bumber has corrosion under the paint and it is causing the paint to chip away the dealership if refusing to accept any resposibillity and are saying it is from stone chips from the road. You can clearly see that the paint is bubling from under paint and still ALAN DAY VOLKWAGEN are saying it is stonechips. What should I do....

Never heard of the lights problem sorry.

With the paint problem, perhaps go to a decent spray shop and get their opinion before going back to the dealer then VW UK if they don't help? If you are within your first two years warranty it is a manufacturer issue anyway.

Hi nbusin,

Regarding the lights - not heard of the same problem myself but it sounds as if the multi-block connector at the back of the light unit is only making a partial connection. Is it possible that someone (you/the dealer) has removed the headlamp unit to fit a bulb and not wound the unit fully back into its housing OR that the winding mechanism (in the engine bay) or light unit housing has broken, allowing it to move. Try here Clicky for detailed pics of the headlight housing and what it should look like
Just a thought though - if your car is in warranty why isn't your dealer sorting this problem out for you?

Regarding the paint issue - I'm not sure what you mean by corrosion (as the exterior of the bumper is plastic
) and it's difficult to comment without pics BUT if the paint is clearly bubbling from beneath and the dealer is verbally saying they are unwilling to address the issue then in the first instance I'd take some pictures (just for evidence), approach a professional body-shop for their comment/quote, put my complaint in writing in the form of a '7 day' letter - pointing out the paint warranty/comments of pro-bodyshop and send a copy to the dealer with a cc to VW Lux support.

Hopefully this will demonstrate you are unwilling to roll-over and accept their initial position and encourage them to take a second look at the issue.

Hope that's some help

Yeah ... I had similar problem with my headlights flickering..... it went in and apparently it was due to faulty bulb causing unit to over heat.... was resolved at no cost to myself...

I had a Xenon replace under warranty in what sounds like similar circumstances. the bulb's connectors were faulty, causing it to cut out when I went round corners etc.

My guess is it's either the bulb or the connector at the back of the headlamp unit.

WARNING - don't try to tighten the headlamp unit using the spanner thingy provided. Very easy to over-tighten and break something. Then it won't be covered by warranty.... Had this happen to me and the nice Treg techie and I spent best part of three hours dismantling the front of the car to fit a new headlamp cradle. No fun at all.

Short story - take it to the dealer, let them break it.

Having exactly this problem too at the moment - control unit has been changed but that has not fixed it - headlight unit being changed on Monday - hopefully that will sort it.

This is most likely related to the position sensor for the headlights. Ask the dealer to check that.

Hi, This is relevent to HID lights only.
Try swapping the bulb from one side to the other, one of three things will happen.
1. Problem solved, unlikely but possible.
2.the light which is going out moves to the other side. This is a good thing as it means the fault is in the bulb, about ?50 should see a replacement. check out http://www.hids4u.co.uk for good prices and next day service.
3. The fault remains at the same side as the original (despite swapping the bulbs). This is a bad thing as this means the fault is proberbly in the Ballast unit. a sod to fit and about ?100-150 each side.
bulbs do go funny and start to flick off for a couple of seconds and then back on under cornering acceleration or braking. but swapping them over is your first job in narrowing it down.
Cheers

ONLY AN EXPERT SHOULD MESS WITH HIDS!

Sorry for the capitals but the high voltage used by HIDS can be VERY dangerous if you are not a reasonably competent spannerman. I am but I still wouldn't change HIDs bulbs or do anything else around them for that matter.

This car is under VW warranty and the dealer should deal with this immediately especially in the winter. I once had a similar problem with Xenons on a BMW and Sytner Solihull told me to come back in a fortnight!
Thankfully Damon Hill at Warwick sorted it out on my way home the same afternoon.

The fact the light flicker happens as the car goes nose up under acceleration or nose down under braking indicates a loose connection so get on to your dealer immediately, tell them you have a safety issue in that the lights go out unexpectedly and you want it fixed pronto, Tonto. If need be, get lairy by talking to the dealer principal and tackle him about the paint too while you are at it!


Let us know how you get on.

Had to change one of the headlight bulbs, and now the warning light has flashed a couple of times. On checking I've discovered the headlight unit isn't quite tight enough in the recess, causing the side bulb not to light. I've tried tightening the assembly with the spanner cautiously.

Talking about being over engineered. I've figured out why the light housing wasn't locked in it's recess, causing the light unit to part company with the connector. On sliding the light unit back in it's recess, you'll hear at first a click as the side spring engages, and then once the light unit is flushed with the bodywork you need to push the unit inwards as you are turning the light removal tool (in the direction as indicated to close). There will be a bit of resistence, and then as you push the light unit in harder and at the same time turn the spanner there is another click as the unit is locked. Don't turn the spanner anymore ! The secret is coordinating your pushing and turning. Us men might find it difficut, but for somebody like scottie who can multi task it'll be dead easy
