(!) Warning on clocks

[Jolfa]

I keep getting this warning, and it's doing my head in, it beeps at me when I turn the corner out of my street (at <10mph I must add, not fast), it beeps at me if I drive enthusiastically, it beeps at me if I brake hard and quite often beeps at me at random...

The owners manual said brake fluid level, which is fine or something catastrophically wrong with something else hydraulic related, everything seems to work fine and fluids are all topped up, what is the problem likely to be?!

[Rocco]

brake pressure acumulator?? that it´s an expensive new part to buy...

[Error404]

yeah the "Bomb" is a likely culprit...., tons of threads about this, but if all the fluids are ok and everthing else worls its noramlly the bomb.
Do search for "Bomb Test" to see how knackered yours is.

IIRC the Febi ones are about £120 delivered off Custom Auto Craft

Mine did that shortly after buying the car. Levels all looked fine but I topped them up ever so slightly and that cured the problem. 11 months on and still haven't seen it again

Good answer, will be trying this first!

Is there a thread for this bomb test? I've just searched and theres loads about it, mainly people saying they tried the test but nothing about what the test actually entails? From what I've just read it affects how hard/soft the pedal is but mine feels ok to me?

Also, I don't have to be braking for the warning to go off, and the amount of beeps I get varies, 1-3?

yeah i have had that problem on a couple of s2's.Was the power steering fluid that was low although looked ok,maybe the level sensor needs sorting?

Cheers I've started to get this and I only changed the bomb a year ago, will put more fluid in it

Even a slightly low level of PAS or brake fluid can trigger the warning, so yeah, top up first!

To test the bomb pump the pedal with the engine off. It should go hard after about 25/30 presses. Anything less than 20 or so means the bomb is on its way out.

Be careful with the above test as it's a guide only and not always 100% true. I know my old bomb passed the above test and other members with duff bombs passed.

Hmm. My peddle is rock hard all the time when the engine is off.

It moves a few mm but no more then that.

This has always been the case even after fitting a new bomb.

Test write up http://www.s2central.net/brakes_06.html

Also note the PAS will trigger the same damn symbol.

It can also be the level senders themselves, check both the hydraulic and brake fluid levels and clean the connections to the level senders. Even better have some one sit in the car whilst you fiddle with both senders and see if either sets the warning off.

Surely it's bound to go hard quick with the engine off due to a lack of servo assistance?

Will check all fluid levels and top up a bit anyway, and all plugs/wires nearby for a start then

[bluequattro]

i had a 16 valve do this, topped fluids up n it went away for the mot, came back day after!
Leak on bomb i think
not check the 20 valve yet, but suspect bomb on that gone too
Anyone got one, buy my car and then fit your bomb!

[Jolfa]

Would a bleeping warning going off at random be an MOT failure? Is a leaky bomb at all dangerous?
