Yes I know of one instance personally. I would need to get permission from the person involved before discussing the full details including name etc. The car though suffered brake failure on its way to get an MOT and suffered an accident, the claim was refused as the car was repaired by unqualified personnel, this was after the car was examined, he even had to pay for the examination. It was the owner that was working on the brakes.

I've heard of another (I have many motor trade contacts) although it was a good few years ago around 7 or 8.

The case you personally know of sounds unusual. I see no need to give names but equally and see no reason not to give technical information if you have it. Had the MOT expired?
What exactly was wrong with the brakes?
What EXACTLY was the reason given for not paying? (This would have to be an extract of the letter from the insrance company, not what the owner says).
Where there any conditions in the policy regarding maintenence? ( Ichecked mine and there is nothing).
You do not need ANY qualification or licence to repair cars in the UK, even as a business. If the repair had been done by a business then the insurance company would have paid out but would have tried to recover the cost from the business that did the repair. Maybe a variation of this happened, particuarly if for example the car was insured by one person and a friend or family member carried out the repair at no cost. The insured may have forgone the claim to protect the person who did the repair. This type of activity by insurance companies means that 4 wheel drive clubs recommend that members don't do free recovery or tow cars unless the owner signs a disclaimer. Insurers have claimed recovery caused damage to cars and gone after the person who was just being helpful.

DIY does not invalidate your insurance.

The lesson to learn from that is if you do your own repairs make sure you know what you are doing and do it properly. Then it will never become an issue if the the car is examined and no fault is found.

Hi Robert.
Yes it was unusual. I really don't know all the circumstances without taking to him, whether the MOT had expired I have no idea, the only other thing I do know is the insurance repaired the third parties vehicle.

That's a big difference sounds like he worked on the brakes and they the job wasn't don't right and caused a the failure
Big difference between that and doing the work correctly in Which case you should not have any issues
 
Hi Chris.
I found out the problem. It was on his Rover 75 and the brake pedal was worn at the bush so was sloppy and caused the stop lights to come on when driving. He fitted a replacement from the scrappy. The car had one months MOT left and he's a good home mechanic. On The way to the MOT a vehicle stopped suddenly for a missed right turn, he hit the brake pedal and it snapped (ABS plastic) he didn't stand a chance. What i didn't know he is still in dispute with the insurance company and that's nearly three years ago!

Got LED dual lamps and special flasher unit ready for the upgrade.
I will update upon installation.
Hoping for little trouble....CANBUS LED lamps and adjustable flasher as the lamps have lower resistance
Brighter lamps here we come...

Hi.
In fact LED's have higher resistance than filament bulbs, hence the reason "Canbus" ones have resistors across them to lower the resistance so the Canbus doesn't show up errors. Even with these resistors they are higher than a filament bulb and this can change flash rate.

I tend to use non canbus bulbs and fit an external resistor as with the resistors in the LED lamp they run quite hot.

I think you need to double check that
Resistors can't be used to lower the resistance of a circuit
Resistors as per there name as designed to add resistance not lower it

Really!!!!!
Your talking to an HNC in electronics young man.
The resistors are in parallel to the supply which acts as a load to the supply so the canbus "Thinks" it sees a bulb filament which is a few ohms when cold. The fiat canbus seems to work with a 47 ohm load, much higher than a bulb filament.
 
I agree,

The Canbus kits or Bulbs have a resistor in parallel to lower the resistance as seen by the body electronics unit.

I have not had any errors from the LEDs i have fitted, the only thing i have noticed is that they flicker very slightly when off, this is due to the leakage current from the drive electronics, it is not an 'issue' but if it really bothered you, fitting 'Canbus resistors' would remove that.

once the car powers down it stops, you only notice in the dark when you are outside the car with the car unlocked but the ignition off.

as seen by the bcu
isn not the same thing as the leds themselvs having a higher resistence then the fillment bulbs
 
Hi.
If you look at the live feed to the bulb on Canbus systems on a scope you will see a square wave, this is why LED lamps flicker when off as they respond to this whereas a filament bulb has inertia..... warm up time.
 
To be accurate issues when fitting diffent lamps have nothing whatsoever to do with the CAN bus. The issues are caused by the filament failure detection circuit. This monitors the the bulb filament resistance when the light is off and / or the current consumption when the light is on. The filament monitoring is one by the Body Computer. The only connection with the CAN bus is tht it is used to communicate the sttus to the instrument cluster nd EOBD port.
