Hi all,

 

Any idea on these beauties?....It all went dark on the way home...

 

Central electronics:
00447 - Function Limitation due to Voltage to High
00907 - Intervention load Management
01516 - Terminal 30, Left
00927 - Terminal 30 (Right)
00978 - Lamp for Low Beam; Left (M29)
00979 - Lamp for Low Beam; Right (M31)

 

... I reset them but these haven't changed.

 

Having charged the battery and rest the the fault codes again I'm left with

 

00978 - Lamp for Low Beam; Left (M29)
00979 - Lamp for Low Beam; Right (M31)

 

still no lights :(

I have no experience of this issue - my car repair experience is more switches/wires/fuses/lamps* than software wrangling -

but what else is wrong besides the error codes?

 

are all the car lamps out, or just low/dip beam on both sides?

 

are the headlamps original filament lamps, or LED substitute?

 

 

In the meantime, have you had two lamp failures? - replace whichever lamp is easiest to change, and check the fuse(s) while you're at it.

 

 

Regards

 

JohnH.

 

*lamps give out light on a good day, bulbs are planted in the ground.

00978 - Lamp for Low Beam; Left (M29): Open or Short to Plus

Possible Causes

• Lamp for Low Beam; Left (M29) faulty
• Wiring/Connector(s) from/to Lamp for Low Beam; Left (M29) faulty
• Control Module incorrectly coded

Possible Solutions

• Check Lamp for Low Beam; Left (M29)
• Check Wiring/Connector(s) from/to Lamp for Low Beam; Left (M29)
• Check Control Module Coding

00979 - Lamp for Low Beam; Right (M31): Open or Short to Plus

Possible Causes

• Lamp for Low Beam; Right (M31) faulty
• Wiring/Connector(s) from/to Lamp for Low Beam; Right (M31) faulty
• Control Module incorrectly coded

Possible Solutions

• Check Lamp for Low Beam; Right (M31)
• Check Wiring/Connector(s) from/to Lamp for Low Beam; Right (M31)
• Check Control Module Coding

In plain English - check visually related wiring for shorts (cuts, rubbing against sharp edges or hot areas)

- then check the bulbs of low beam lamps; replace if necessary.

Yes, I had a look at this... I checked the fuses, reset the fault codes. Checked/looked at the wiring and then replaced the bulbs...resetting the codes again... Tada - back to life! SO, asked the company that I bought the bulbs from in October if this was normal for such a short lifespan and they said the Phillips racing vision bulbs have a 200-hour life expectancy and that that I would have done that since October... So avoid these bulbs would be my initial thought - unless the bulbs I've just put in go as quickly.... Bosch Gigalight Plus 120...

 

I'm not sure if you thanked me or Like-d my reply. Probably it's because English is not my native language...

From your description of the issue I had only a single thing unexplained: WHY did both bulbs burn? If I would have known that you replaced the original low beam bulbs with 'better' bulbs made by Philips, Osram or Bosch that promise extra light using bull#### marketing names (Ultra, Giga, Extra + Vision) I would have told you to replace directly the bulbs. Stop wasting money on overpriced, short life bulbs. They are designed to fail in a short time. It's a scam that gets big money to unscrupulous companies. Simply put, the bulbs give more light by passing more current through them. They run very hot, they are very sensitive to mechanical/thermal shocks, and they can fry related circuits too. Not to mention they have the bad habit or failing both at night.

To gain certification, they must still be the correct wattage and lumen output for bulb design (H1, H7 etc). At least this applies to the UK and EU although Canada maybe different.

 

Instead, the filament is normally designed to produce a smaller, brighter light source which gives the % improvement for a section of beam pattern for a specific headlight design. It's this filament redesign that makes them more fragile and decreases their life span rather than consuming more current.

 

I agree with your sentiment though. I gave up with 'performance' bulbs and used Philips Ecovision H7's which lasted very well.

I've had high intensity bulbs on a few cars (Osram Nightbreaker and Philips Xtreme Vision).  Yes, they burn out a little quicker but I've never had any significant problems.

 

On certain cars with poor headlight output, the increased visibility they give is worth the increased replacement cost in my opinion.

I was of the same opinion with the nightbreakers, I got over 18 months out of them but the philips racing vision... just over 4 months!!!! Not worth it... see how these Bosch Gigalight Plus 120 last. I was trying to choose between the GE's and the Bosh - needed to make the choice there and then in Halfrauds...
