Cant open my bonnet on my audi a3 think cable is stretched need to check water oil etc

Can you see the end of the cable through the front grille? On some vehicles you can use a extra long flat screwdriver to push the release through the front grille.
Some S3 and A3 models have a small access hole between the bonnet and grille. A thin wire hook and a lot of poking around can release the bonnet.
if this doesn't work you might have to destroy the front grille to get access.

Sounds like you have a cable problem take it to a garage.These are very tricky to replace and expensive.

Check both ends of battery's earth lead.
Remove, clean all surfaces with emery/sand paper, replace and seal with grease or vasaline.
If this is not the fault - it worth doing and eliminates something.
Hope this helps.

Give some more details of the problem.

hi, some cars have the bonnet release under the drivers steering wheel, right hand footwell, left hand foolwell some have an ignition key in the front of the grill under a flap. gerry

Bonnet not closed properly

They normally last long, they need to check that the rotor cup that the speed sender gets its signal from is not damaged and has the correct spacing. Also check for oil contamination from leaking cam seals.

check with your dealer to see if it its still under warrenty they should fix any problem for free.

the indicator lights flashing constantly might be a warning from the car that all the doors have not been closed properly

after writing this ^^ i think that the system that tells the car if the door is open or closed it damaged or broken
and needs replacing

try leaving all the doors open and lock the car do the indicator lights flash contantly?

you need to get a dianostics done but due to the reson that it is intermmitant the problem will not exist when you get to the garage

check all the sensors that tell the car if the door is open firstly

Hi,

I just wondered if you have had this repaired yet and what was causing it as my Audi A3 2005 model has exactly the same problem!!

In response to bs77bird - the two things are definatley related. When i am stationary and the bonnet light is on neither my front wipers or my windscreen wash work. when im moving, my wipers do work, but my windscreen wash still doesnt. When the light turns itself off occasionally, both the wipers and windscreen wash work when im stationary and moving.

Any help would be great as i dont want to get ripped off for something i could potentially fix myself!
