How long should it take without taking the abs pump off ? and is it possible with the brake pipes in the way? i want to do this tomorrow after work :smiley:
cheers
Mike
-
Yes it's possible and takes 15 mins if you have the right tool and no rusted/damaged bolts.
-
Ok so i have changed the ecu which did actually take 20 mins or so :smiley: but i'm getting the same codes especially the pump one so i am guessing the actual pump is at fault! if i replace this do i need to use vag com to get it all working again or can i just bleed the system and off i go again ? cheers
-
Hey dragongreen did you replace the ecu with identical part number and letter at the end,reason i ask is i believe i need to change my abs/ecu and last time i tryed i swapped mine out for a replacement with same number but different letter and this didnt work ,incorrectly coded or something :undecided:
-
There is a question in this thread I would also like answered.
When bleeding the brakes do you need Vag Com to bleed the ABS pump? Or will it bleed using the 'normal' procedure of simply bleeding each brake caliper.
The reason I ask is to try to shed some light on Dragongreen's question, plus I know that my old Vx Omega needed Tech2 (the equivalent of Vag Com) to bleed the pump.

Alright mate yeah exactly the same it's taken me ages to track one down as it only seems a select few vr6's or late 16v's have the pump and ecu i have :sad: so after seeing one advertised on the net i had it however the ecu seems to not be the problem so i am now going to try the abs pump which it came with and hopefully sort my problem out :smiley: cheers

Ihope someone can help us on this as i would like to jsut get on and do it myself rather than pay a garage just because they have full vag com :sad: if its a case of bleed as normal i will do it at weekend :smiley:

Mike how come you thought you needed to replace the abs module?

Mike how come you thought you needed to replace the abs module?
It was something i read somewhere maybe on here they said to try a different ecu first with the code i'm getting and you can sometimes try and fix your original one somehow following a guide but as it turns out it hasn't cured it so it may well actually be the pump this time there quite common to fail on mk3's i believe :cry: i'l update if i manage to get it done getting fed up of no brakes now and again etc lucky i'm used to older cars where brakes hardly existed :laugh:
-
How do you know the replacement ecu hasn't failed?
I replaced one and it had the same faults.
-

This is true but it was bought in confidence and was said to be in working order and is throwing up the same codes apart from 2 i think it is and the pumps do sound to be the culprit i'd rather replace both and take my chances but finding the exact ecu was hard enough this time so doubt i'l find another anytime soon i'm confident its the pump now :cry:

Ah right,well my abs is out of action most of the time now,when the light is not on i have tested it and it works great so i know the pump works,code that comes up every time is rear right,ive changed the sensor,,speed ring looks clean and secure,ive even swapped the rear left and right plugs over and it still throws the same code up :undecided: also the handbrake light will come on after a while totally random,either sitting in traffic (not on the brake) or just cruising along,i believe this to be another sympton of a failed ecu, tryed a couple of different modules but they were not suitable as in one was from an 8v and the other was vr6 but had a different letter at the end,the quest to fix this continues :cry:

This is what i am getting the handbrake light is on mostly all the time but funily thats when the brakes are at there best if it goes off then they go all funy. After reading a few things i thought it was the ecu but now i'm unsure still talking about it more i'm going to try swap out the pump anyway just for good measure. I want this sorted really as the esp works through the abs system which is a good feature i also believe the 16v has traction control built in to it also? i'm getting codes for all abs sensors and the main code is the pump failure code so... all my abs sensors and rings are brand new as not long done them all using genuine parts! doing my head in :cry:
-
Tell me about it,had car two years and there hasnt been a single day that i havnt seen that evil orange light,burnt out two bulbs so far lol,never had pump code come up though,yeah i would like to have a play with the edl system too even if it might be a bit primative,two months till mot :evil: calling all freindly m.o.ters (again)lol

yeah i bought mine and the brakes worked perfect scanned it before i bought it etc had it now year and half and i think this started about 8 months ago and has taken me this long to find a pump and ecu the same :angry: i've got mot in september but luckily i have suspicion it will pass :wink: but thats not the point i really want this sorted :smiley: hopefully we can help eachother sort this i'l keep this updated when i get the pump fitted :smiley:

Sweet,yeah brakes are a nice thing to have all the time ,might be getting a gloustorian MOT this time :laugh:

Just a quick question did u clear the codes after u fitted the ecu???? as this can result in error codes coming back,
-
Be VERY careful when handbrake light comes on. This is the sign of complete system failure and it means the rear bias isnt working. I found the out once when i broke hard and the rear end tried to over take the front and nearly put side on into a parked car.
That means ECU has failed!!
If you have an ECU send it to me and i can see if i can repair it. :wink:

Thats the advice you gave me a few months back and replaced ecu all good now

yes i removed the codes after refitting the new ecu and they returned after a small trip :angry:

Yeah ive had the back end almost do that :sad: that's one of the reasons i'd like it fixed can be very entertaining sometimes. I will be very annoyed if i have bought a ecu and pump that is knackered i will let you know if i need your repair skills mate cheers
-
Bleeding the ABS pump is a b!tch to get all the air out, my 2p :smiley:
-
If u got vagcom you can do a test on the pump if u need a pump i got a spare and ecu as i bought a couple when my went and all been tested..
-
Well after nearly two years mostly in the company of the abs light,it has now finally been extinguised, hoo f--kin ray,
Tshirt2k worked his electronical witchcraft on my abs module and sorted it,top bloke and does a quality job too .One is most pleased :smiley:
-
Mike bring it down mate, av got full vag com so can check it all. Well bleed the system up at the same time if you want aswell buddy. You know where I am

nice job :smiley: think i'l send tshirt my spare ecu then :smiley:

Cheers liam i'm on shift this week so might be able to get down to you one morning this week :smiley:
-
Just giz a txt when mate and well scan it see what's going down. U may have to code the pump to ecu aswell. Gd job I've got vag com
-
really need to get this sorted now :sad: couldn't be fixed with vag com :sad:
-
Mines still working mint :smug: PM tshirt im sure he will sort it mate.

sounds good :D i just have messaged him he's off on holiday he said send it in few weeks i'm still sure its my actual pump though :sad: cheers
-
I had my complete abs system off the car, and in bits to clean and paint, Refitted and bled the brakes using the usual method and worked great, no codes or abs light and no vagcom needed. Only think you need it if you have changed the pump from another car.

Sounds good although my problem may just be that i'm looking to replace my pump with another second hand unit to see if the pump is infact the problem. I am thinking now though if thats the case with the pump then surely it would be with the ecu ? I can't find a definative answer anywhere :sad: i don't mind bleeding brakes etc but i'm worried i'm going to stuff this up if i swap the pumps over and it won't bleed or something :sad:
-
You have a known working pump and ecu as a pair not on the car non? put it on bleed the brakes youll be fine :undecided: :smiley:

well it was sold as being said it was working yes so i thought i'd try the ecu first so i have taken the ecu off the new pump and stuck it on my original pump to which there is no change in the codes coming up so only option really is to see if tshirt can find a problem with my original ecu if there are no problems then it is definately the pump so i will have to try the new pump anyway :sad: i cant see why it wouldn't bleed up the normal way myself with matching ecu and pump like you say should I try it?
-
Mate i would just go for it ,does your abs work at all ,now and again?

yeah if the handbrake lights on it works almost fine but if its off then it hardly works at all :sad: might just do that once i get ecu back lol
-
Handbrake light? That means bias isn't working.
-
My handbrake light comes on after a couple of minutes and then stays on. So then I guess I need to repair the abs ECU then?

Don't brake to hard. You may find rear will lock up.

yeah could be back end locks up sometimes getting used to it now :sad: what does that involve so it might not actually be the main pump after all? bloody vw :sad:

this is what mine does but sometimes it wont come on for half a mile or so which is when its most dangerous as i have hardly no brakes :angry:

This is what mine was doing coupled with the abs light,ECU was at fault.
-
It has been locking up on loose surfaces like on a dusty road and the front end has tried to jump into the hedge!

Yours really does seem to point towards ecu seeing as its making your brakes not work,i would try driving with it unplugged until you do the job at least then the ecu cant tell the pump to kick in stopping you from braking as normal.

sounds like a plan does that work lol will basically be like no abs I take it? but will hopefully not try to kill me all the time :smiley:

A failed ecu won't cause brakes not to work. It will just not control pressure applied to front and rear wheels.
ABS light tells you ABS has a fault and it's disabled. If handbrake light is on too I'd be very careful when driving. Rear will try to overtake front if you brake hard as weight shifts forward and off rear wheels.
Unplugging abs will be the same. It won't help you much.
-
How much are we looking at for an ECU repair?
Would I need the light on the dash reset or would it sort it itself?

The later is my problem i need to sort this asap MOT in october :sad:

Bba charge around £200. Pm me. I should be able to sort you out after my holiday.

When i say it causeing the brakes not to work,i think the ecu is controlling the pressure applied but for mikes case its stopping him from braking sometimes as if the abs is kicking in in a non abs situation ,mine did this some times no matter how hard i pressed the pedal it would not let me stop quickly and nearly shot out of a couple of junctions,this stopped when ecu was unplugged but as said brake bias will not work.

Ok yea I get ya. Sometimes, Abs pump will operate too when brake pedal not even pressed.
