ABS light on for 10 secs first start of day, then normal...

Post by 2065 » Fri May 06, 2005 9:59 am

Hi

My ABS light always takes about 10-15 seconds to go out after the first engine start of the day... on subsequent starts it goes out near immediately as it should.

The ABS itself works fine.

Any ideas?

David.

This is not a problem: Its because the first time, the accumulator has had all night to lose its pressure, and has to "recharge". Subsequent times there is still residual pressure in it so it takes less, if any time to charge.

Bit like the old citroen BX's, the hydropneumatic suspension used an accumulator at the top of each strut. If left all night, the car would gradually sink right down onto the floor, more than just if left for a hour or two

The voices in my head might not be real, but they have some pretty good ideas..
