Red braske warning light appears when warm starting,

[debjohn]

HI I HAVE AN A4 2,0 TDI SE B7 when starting from cold there is no problem at all, it starts without turning over hardley, as it should, if left a few hours from hot it starts fine again, but if left for a short while ie hour or less. then ign on states OK, then when i crank it over the red brake warning and 3 beeps appear only while turning over to start, once started it disapears and stays off, only happens when left for short while, does not stop on while driving, any ideas please,

Have your battery checked

From a phone that's smarter than me...

never had a problem with battery does not die or anything, but will get it checked all the same

Kite is suggesting that the ABS is throwing a fit because the ABS module is seeing a low bat condition while you are cranking.... Others have reported this scenario on heavy cranking in other forums. I'm not saying that is your cause... Getting a scan for fault codes might lead to a better diagnosis.
