Ms dieselfan's 1.4TDI 2004 BHC do not behave as one could wish...
Last months hazard light has now and then started to flash during the night, with an empty battery as result when she enter the car 07.00 to go to work..
One touch of hazard switch stop hazard blinking. Until it suddenly starts to blink again, typically during the night...
This car is delivered with alarm, but the horn/sound was disconnected by last owner.
I have tested the door mounted microswitches
Instrument cluster and ECU is from an AMF 2002, and there are some functionalities that is not working (engine warning light and limp mode first time one pass 2500 revs, and remote lock with key/keys)
VCDS scan identify intermittent cooler fan controller issue and key issue. These are old and I assume they are not related to the hazard blink since that problem has appeared now , while the other fault codes are one year old.
I have changed four indicator/hazard relays over the last 12 years on our other A2's, so I have some experience with that relay, but this time I have no issue with the indicator functionality, which I find a bit weird...
I have changed the relay and hazard switch to used ones and then the car was ok for three days so I thought I had found the defect... then it started to hazard blink again... Used parts came from a donor car that I do not know in detail so that's not ideal...
My hands are crippled due to arthritis so I really struggle to get the indicator relay out of its bracket, so from now I wrap the relay in cell foam and put it in the ashtray... so now it is easy to change it.
I hope someone can come up with a smart way to proceed.
Hazard blinking do still start to flash on random, even once while driving...but most often during the night with locked doors. 6-8 times per week.

- Should I disable the alarm? if yes, how do I do it?
- Should I buy new both blinker relay and hazard switch new and change them?
- What should I trouble search ?
