Upsetting times with my otherwise very pleasant 2003 A4 1.9 TDi quattro because it's now the second time I have been told the hazards are flasing on the vehicle and when I go to turn it off or unlock it the car has forgotten my remotes!
My mechanic friend suggested my first port of call would be to check the scuttle panel to ensure no water is entering the passenger footwell. I checked the CCM box and it does look dry as do the wires leading to it.
Next I checked the pollen filter and that is dry as is the plastic housing it sits in. Then I took off the various bits in order to remove the battery, quite heavy when you are trying to lift it with outstretched arms! Then removed the battery tray that it sits on and found the drain grommets, it was all dry down there and the grommets have either been modified so that they are very open or they are of a different type that do not have a normally closed slit in.
Anyhows, it doesn't seem like water ingress, I've checked for fault codes and the auto-scan hasn't pulled any up, can anyone suggest what to try next? Does a faulty alarm (it doesn't sound when the hazards were flashing) or dead alarm battery cause this issue to?
Here's hoping someone can help.
