Hi Gareth, what would you say the solution is?

Having read a few forums and looking at similar symptoms, I've decided to swap the master cylinder and servo out. Will let you know how it goes.

First set were Pagid, Second set are Mintex, to save dosh. They were fitted at my local MOT garage, who so far has been reliable.

Im trawling the forums and the symptoms do suggest a servo and master cylinder.

My next step, is to get the car on an MOT testers brake resistance roller. Mechanic is going down the route of the other brake not working properly, if not at all. That would explain the lack of wear on the new disc on that side.

Hi Gareth,

Thats the flexi hoses swapped out for brand new ones to no avail.

Any more suggestions? Mechanic reckons new abs pump next

Hello Owen,

I’m sure you will appreciate that it’s always difficult to diagnose anything without examining the animal. Having read what you have said, I would be beginning to suspect the brake flexible hose on the offending side. These can deteriorate internally and as they break up, can effectively form a ‘one way flap valve’ which allows the pressurised fluid to move into the calliper, but not to adequately allow the pressure to be released. 

Just a stab Owen, but....

Kind regards,

Gareth.

Gareth, many thanks for the reply. I'll mention this to my mechanic. All I want is a solution to this! driving me mad!

So after recently having new discs and pads, I have found that the N/S front calliper is a little sticky and gets very hot after a decent drive. It got to the point where after about 5 mins up the motorway the steering wheel began to judder, and even more so after braking. 

the other day with a few people in the car and on a hot day I lost all braking power with a spongy pedal. Brake fluid was over flowing from the reservoir. 

I took the car to my local mechanic who stripped the callipers, degreased and bled them. Everything seemed to be fine until it happened again with the wobbly steering and worser braking. 

With a suspected warped disc (brand new pagid), I opted to go for a new set of discs and a refurbed calliper. I drove the car again for about 10 miles up dual carriage way and a little bit of B roads. I understand that new discs and pads get hot but this was ridiculous compared to the O/S which was luke warm.

The next stage having agreed with my mechanic is to see how they bed in over the weekend, then he will get the car on a brake testing bed that they use for MOTs on the monday.

I have looked through the cars history, and have noticed that it has had issues with the same front N/S brakes before. This will be the 3rd calliper it's had.

The car is partial service history, 2003 with 53k miles. (yes 53k miles).

Has anyone had any similar experiences or could offer a solution? I am so close to going back to a trusty swedish battle barge

cheers,

Owen

Hi Steve Q,

I found the location and pulled some trim back just to confirm, just need to source the sensor. 

Part code is 8E0959643 RB4 HV.

Now I've found hundreds with the 8E0 bit but none in the UK or cheap with the RB4 HV.

Do you know if it has to be that specific part???

Cheers 

Ok, 

So I have found a code, 

Crash sensor side airbag, drivers side (G179) sporadic. 

I am led to believe that this is located in the base of the B pillar. 

Does anyone know the best way to gain access and remove the trim without breaking it.

Cheers

Hi everyone,

I have a B6 Avant 1.9tdi quattro. Just had it serviced, and replaced a battery today. 

The other night the airbag light decided to intermittently come on. I put this down initially to having a dodgy battery as other lights were coming on and off on the dash. 

I had the car serviced and they cleared all faults, and informed me the battery was kaput! So changed the battery and the Airbag light is still on. Now and then it'll flicker and come back on. I have checked all under seat connections and they are fine. Just not had chance yet to disconnect clean and re-connect. 

Could anyone else offer any help and advice as to what it potentially could be.

Cheers

Hi everyone, new to the forum, from Leicester. 

Just bought a 2003 A4 Avant PD130 Quattro. Already sorting bits and bobs out so hope to be able to pick everyones knowledge, brains and know-how. 

Cheers,

Owen
