Headlight Bulbs blowing on MK7 Fiesta

44 posts in this topic

Just so you all know...

My bulbs still haven't blown. (now at 19k & 7 months)

Shortly I will begin the process of procuring a spare bulb supply.

Will be getting the (allegedly) 80% brighter Philips Xtreme Power bulbs. (NON-Xenon)

I'm talking about these bulbs btw

Just changed my main and dipped beams most awkward bulb change ever!

Seriously i'll get some pics up, who ever decided it was practical to remove the whole unit to change a bulb needs shooting!

I've heard it just 2 screws and a clip? ive heard its a nice simple job? reading another topic on headlight changes?

Its two screws and a retaining clip but the fact you have to remove the whole unit to change a bulb is so stupid! and also you have to assert pressure when you secure the unit back into the main clip at its base just dosent feel nice :blink:

Summary

Should a customer express concern about repeated, blown headlamp bulbs on one

or both headlamps, the probable cause is a voltage spike in the electrical

vehicle system.

• NOTE: Fiesta 2008.75: It is not required to remove the headlamp

assembly on the right-hand side.

• NOTE: Kuga 2008.5: It is not required to remove the headlamp

assemblies completely.

To rectify this concern, an resistor wire should be installed on both

headlamps between the current electrical socket and the headlamp bulb H7.

Now I know why I go through a set of bulbs every two months. Thought it was the auto lights and the length of time the lights are on that was shortening the life . :angry:

Anyone know the price of the Resistor wire ?

Thanks to all for the information, recently bought a pair of resistor wires with Finis code above, for £24.38 all in, I fitted these along with a new set of Philips X-tremeVision+100% H7 to replace the blown PIAA Extreme White Plus.

I did not mind paying for the parts, as I had already carried out a couple of bulb changes/bulb upgrades following the very early information on here by bigjock (Thanks mate, your experiences of bulb changes on the MK7 helped me back then) nearly 2 years ago, anyway, just did not want any potential hassle with the dealer over this, my peace of mind is worth more than £24.38 Lol..

As long as this 'fix' works and the H7 bulbs last longer, I'm happy.

Thanks again to all that posted on this, would have never known about the 'fix' otherwise. :)

Sorry to Bring Up this Old Post...!! But..!!

My Passenger side H7 (Dipped Beam) Bulb has just Blown.!! I Have Osram Night Breaker bulbs Fitted since July 09.

I Think the Bulbs have Lasted Fairly Well.... But..??

Reading old posts.. It appears My Fiesta was Built during the time Ford admitted to bulbs blowing possibly due to a voltage spike.

Members have suggested.. "To rectify this concern, an resistor wire (Finis Code 715 479 at £10.31each) should be installed on both

headlamps between the current electrical socket and the headlamp bulb H7".

As My Warranty has Expired.. I would like to Know is this the Correct Finis Code..?

& could Someone Please Show or Tell Me How these Resistor Wires are Fitted..?

Many Thanks.!

Dear Reader,

Please have patience and fortitude, my story below will take a minute or two to read. I really need good advice from anyone who has experience of taking on Ford with a technical fault that is clearly a design flaw...

I have arranged replacement tomorrow by my Ford local dealer (from whom I bought the new 58-plate Mk7 Fiesta Titanium 1.6 TDCi) of the latest of several (dipped) headlamp bulbs that have blown since buying the car. Bulbs in both headlamps have gone at different times, each time after only a few months of average UK use.

The last time I did this, after several previous replacements, for some of which I was charged, some kindly not, on dispiritedly taking it in again I was informed (politely as always) that Ford had come up with a 'fix' for the problem, caused as mentioned earlier in this thread, by voltage spikes. I arranged for the kits, consisting of a resistor 'choke' behind each bulb socket, to be fitted (for which again the dealer considerately waived charges, evidently valuing my patronage; the car was by that time out of warranty) simultaneously with the blown bulb, and drove away, hoping not to have to call again, for a reasonable period of time, anyway.

(BTW Although I have personally maintained a wide variety of vehicles for many years, I shied away from trying to replace the bulbs myself after looking at the very cramped space in which to work).

Now it's clear that the 'problem' hasn't been resolved by the 'fix' kit, as another bulb has blown after only a couple of months.

I have asked my dealer for a full list of the service events involving the bulb replacements, and for the fix kit installation, to document the history of this issue. It is clear to me, particularly now that I have learned that some Kuga models also suffer from the problem, that this fault arises from a design flaw in the car's electrical system, or perhaps the control unit. I imagine (but do not know for sure) that the control system software plays a part in the charging and lighting power functions of the car, so it seems logical to suggest that a software patch may be required.

I have no idea how Ford manage these issues, and I am well aware, this being the 6th nearly-new or new Ford that I have owned, that they are very reluctant to admit to faults in their products, so tackling the supplier head-on may be a wearisome and ultimately unproductive process. I hope to enlist my dealer's assistance in doing so, but I have no idea what are the chances of success.

This Fiesta was one of the early ones off the new production line, and it clearly carries at least one teething problem that has not yet been fully resolved - Ford's provision of the fix kit is an indication of their acknowledgement of the existence of the problem.

I want to find a way to stop this senseless waste of time and money, replacing expensive halogen bulbs that should not blow in their short lifetime. I want to find a way to get Ford to admit liability for the design flaw, and provide a proper solution; one that works, permanently.

Any advice that anyone can provide would be greatly welcomed.

Thank you.

Sam
