    Vw 2007 polo foot brake/abs issue! Help please! Don't want inexperience to cost us!

    Hi,

    Newbie here - hoping someone can help with this ongoing saga...

    The brake pedal on my 2007 Polo started feeling mushy and braking was less responsive. Took it into a local garage to have the brakes checked, and they advised that there was nothing wrong - probably just needed a brake fluid change and bleeding. I had this done, and they called back to say that the brakes weren't holding pressure in the system properly - advised probably an issue with the master cylinder which needed to be done at a VW garage.

    Booked into VW garage and outlined the issue, left the car there for a diagnostic. Contacted me to say that the back pipe from the master cylinder was cracked and needed replacing and the console bushels? needed replacing. I authorised those repairs which were done today. They've now come back to say that those repairs didn't fix the issue and everything is pointing to the ABS system which they want to replace for a cool 1300 on top of what I'm already paying them (~450) and they can't guarantee that this will fix it.

    I've got several issues with this turn of events, and I'm becoming more and more concerned that I'm being taken for a ride here:

    1. If the ABS is faulty, why haven't any warning lights come on?
    2. Why can't VW properly diagnose a problem with a VW car?
    3. As far as I understand, they should be able to read error codes off of an ABS module CPU - they claim the only way to diagnose is to replace the parts?
    4. Searching round online, there is a propensity for ABS units from VWs this age to have a serious fault that should have been recalled and wasn't? If my ABS unit is one of these models, is there any way for me to get some form of goodwill from VW on this? The fact that "everything points to the ABS unit" leads me to believe that they know in advance this is a dodgy unit.

    Can anyone give me some advice here?

    It's not clear to me from what you've said; did they, or didn't they replace the master cylinder? What parts are itemised on the bill?

    You need to ask them what they mean by 'everything points to the ABS system'; preferably getting the answer in writing. I think you are right to be suspicious until given evidence.

    Hi Pete,

    Sorry if it wasn't clear. They have told me that they only replaced the back pipe from the master cylinder (not the master cylinder itself). It was this pipe that was cracked, so I can understand how that would contribute to the "mushyness" of the brake pedal as the hydraulic system would be losing pressure at this point (as far as I understand it). They also replaced the console bushes which I was told at the time we contributing to the brake pedal problem (I naively agreed to this work). I have since learnt that these are part of the suspension and would have no bearing on the function of the brake pedal to remedy a feeling of "mushyness" underfoot, so I am going to dispute why that work was done in the first place as I could have had them replaced at less expense somewhere else. I have asked the head of the garage workshop to give me a call later today so that we can discuss this problem further, specifically why everything points to the ABS and why (if there is a fault in the ABS as they claim) it is not flagging with a dashboard warning light. I am also going to take the car away to an independent VW specialist garage nearby to have it diagnosed properly as I don't trust these guys anymore. The independent garage has also advised me to dispute all of the charges for work done so far, as they haven't sorted out the problem I bought it in for at all.

    In my experience, disputing garage charges after having paid is very much like banging your head against a brick wall. If they misled you into believing the console bushes were part of the braking problem though, I think you should be angry enough to yell at them in a showroom for a fair old while. (Even though I think there is near-zero chance of any cash coming back your way).

    Wise decision to take it elsewhere.

    master cylinder is the most likely to be faulty, did they scan the car? if is the abs some code will show that the abs is the problem, just change the master cylinder

    It is a common problem, they have not followed the correct brake bleeding procedure, I get local garages with this problem regularly.

    Vile Invention

    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.
