Couple Of Problems????

[The MoffMeister]

Hi guys need some help again please!!

Firstly, have recently changed the battery on my key fob for the remote central locking and it seems to be getting worse, im having to stand closer and closer to the car to get it to open and close, any ideas here??

Secondly, if i brake whilst going round a corner slowly or fast (and yes i know you shouldnt so none of that) and hit a bump in the road or something i seem to get a (its hard to describe so bear with me) grinding feel through the pedals and the brakes seem to lose their braking abilities, thing is though i have recently had the discs and pads changed and know it is not this as i had the problemn before the pads and discs change, so yet again any help would be greatly wanted here!!

Many thank's all!!

Sounds like the keyfob is wearing out All I can suggest is have a look at the car's battery, maybe it is getting tired and due for replacement?

What you describe sounds like the ABS system cutting in. If you think it is cutting in too soon, it may be that you have damaged a sensor when the disks were replaced.

Cheers for that but as said it was happening before the discs were changed??

Second point sounds like ABS cutting in, as Muttley mentioned - wonder if it's more likely to cut in if you're going round a corner, as it will sense the difference in wheel rotation and think one of them is about to lock.

ahh i see sounds like it as i did have a abs problem when i vag com'd it deleted the fault and hasnt come back but will get the stealer to have a look! cheers

With regards to the braking issue, if you feel the brake pedal judder then its an idication the ABS is kicking in. Also if you hit a bump whilst breaking the car tends to go upwards meaning the weight [of the car] is less on the tires so braking whilst doing so will be less so.

ABS acts when it senses that a wheel is about to lock up and skid. It does this by sensing the difference in rotational velocities over all four wheels, which is why the antilock sensors are on the wheels next to the disks.

In dry conditions, wheels are most likely to lock up when they are unloaded. When cornering, the inside wheels are unloaded as the cornering centrifugal force transfers the weight to the outside wheels. On a bumpy surface, the wheels spend some time off the ground, completely unloaded, so will lock up if braked. This is why you need to be careful when braking in such circumstances

The feedback to the brake pedal is deliberate, to let you know that ABS is active. It means that you are on the limit of adhesion, and you need to do something drastic if you need to stop quicker, like straighten up or steer to a smoother bit of road. ABS is there to keep the wheels turning and give you some steering authority at times like this, when without ABS you would be in a skid and unable to steer.
