Possible Faults From VAG COM?

I have also had a problem with the ABS and TC Lights. They have been on for some time now and i stupidly paid £66 at SEAT to have a look at it for me. They said it was an ABS Hydrolic Pump Fault that was intermittent. They cleared the fault and it came back on an hour later!! (What a waste of money)!!

Thanks for your help,

Spark

Control Module finder only finds the installed modules for you car. To diagnose the problems in the car, you need to scan the modules for fault codes. Post the results of an Auto-Scan here if you can. It you are running shareware, then you have to go module by module looking for the fault codes. With that information someone here may be able to help you.

The reason the light came back on after you visited the dealer is that nothing was repaired. Resetting the fault code does not fix anything. If the problem has not been addressed, the module will find the problem again and set the fault code again.

 

[cordobabrendy]

yea those messages above are only telling you what modules you have in youre car, open vagcom and go into engien,brake system etc and you can look for and clear faults.

 

[sparky4309]

Right then,

This will explain why i can not see the fault code (I am new to this so you will have to bear with me),

I have done as you stated and there were no faults on anything other than this one in the ABS area:

1 Fault Found:
01276 - ABS Hydraulic Pump (V64)
16-10 - Signal Outside Specifications - Intermittent

As i stated before the ABS and TC lights are on all the time.

I have cleared the fault - gone for a drive - both lights re appear - fault returns!!

Any ideas (I believe that the main ABS unit is v v v expensive) fingers crossed!

Thanks for your help,

Spark

Chemical Al,

are these the 3 green 30 amp fuses that are situated with the battery?

[sparky4309]

Right,

It's time to find the ABS unit and check/follow some wires to see if they are all in order! I have removed the fuses from the battery - lets see what happens.

Any idea where the ABS unit is located?

Thanks

 

[sparky4309]

Now then,

I have taken my car to My SEAT Stealer at Rawtenstall, and guess what .... it's closed! So i then drove to Bury and spoke to the SEAT Mechanics and explained the situation.

He then, after i begged almost, took the car of me and took it into the garage. He then returned - 50 Minuets later, to tell me that he has checked the car and there is no fault with the ABS System. This having been checked on the rolling road and their VAGCOM system.

He stated that he has reset the fault and it will now be all ok.

Less than 5 minutes later, and on the motorway, the ABS and TCS both re-lit my dash.

Is there any way that I can permanently clear these codes from the system, to prevent them coming on under this fault code number?

Any help at all will be of use, thanks,

Sparky

 

[BeartheBruce]

You can not and should not permanently disable these lamps using a diagnostic tool. You can remove the lamps/cut wires.

There is an intermittent problem that needs to be addressed in this car. Until you do that, the code will keep coming back. I know it is not what you want to hear, but there has to be an explanation for this to continually happen. It may be a bugger to find but it should be found and fixed.

 

[sparky4309]

Bruce,

Thanks for letting me that you can not permanently disable this fault code. Initially i paid the £66 at SEAT for a diagnostics check, which they informed me that this fault was intermittent. Its just seems strange that today it has been to SEAT and they also say there are no faults!?

I have run out of ideas now as to what to do next!?

Many thanks for your help,

Sparky

 

[BeartheBruce]

Sparky,

Several of the earlier threads have suggested that the ABS module was bad or the pump has a connection problem or is bad, and so on. Have you exhausted all of those possibilities? I realize that when you have taken it to the pros the problem went away and they were unable (or unwilling?) to resolve it. Short of buggering the system to take the nusance alarms out, you either have to find the cause or live with the lights.

 

[sparky4309]

Thanks again,

I have been back to SEAT today and they have stated that the only way in which they can sort the problem is to replace the ABS Module Unit. I would have this carried out however at a cost of £1032 + VAT AND Labour time!!!!!

This option I am not fond of, added to the fact that the MOT is going to be due in 8 weeks!

You mention 'SHORT OF BUGGERING THE SYSTEM TO TAKE THE NUISANCE ALARMS OUT YOU EITHER HAVER TO FIND THE CAUSE OR LIVE WITH THE LIGHTS!'

What options are available to me (preferably not the expensive one?)

All help appreciated,

Thanks Very Much,

Sparky

 

[BeartheBruce]

Ouch! that price is painful. I have no other solutions for you. If you do not feel there is danger and that the brakes are working correctly, why not just ignore the lights? I would hope that eventually a part would fail in a way that you can detect and can justify the cost to replace it. My fear with ABS systems is that the point of failure could result in a crash. I wish I could be of more help to you.

 

[sparky4309]

Okay,

I have been back to SEAT and they have checked all the wiring, pump pressure etc and told me the fault is only sporadic/intermittent but they cant tell me which area/part needs replacing. They have deleted the DTC code but I returns again and again! Although on Sunday I drove 300 mile round trip with neither ABS nor TC Lights on!!!

I have been told buy a friend that the below equipment will solve the problem:

KWP2000 Flasher

Product Description:
KWP2000 Interface for ECU flash reading/writing over OBD2 diagnostic socket for a wide range of ECU units
Specification:
- Connects to USB
- Supports high speed ECU flashing
- Integrated OBD2 connector
- Led Indications for power/rx/tx

Package includes:
- KWP2000 Flashing Interface with integrated OBD2 connector
- Shielded USB A to USB B connection cable
- OBD2 female to banana cable
-12V Lighter to banana cable

This costs £290 and will solve the problem!

I don’t know what this is if I am being honest and don’t know if it will work.

In relation to the ABS - I have performed a break test with the ABS light on and off and it works both time! I am happy that the ABS is working fine!

I would rather spend the money on some equipment that works, rather than spend over £1k at SEAT - only for the problem to remain?!!

Any Ideas?

Before you spend the money, please have your "friend" explain exactly how this is going to fix a dodgy ABS system.

IMO: You have some sort of HARDWARE problem with your ABS system. Even if those ABS modules can have new firmware flashed into then (something which is by no means certain), flashing new firmware into it is strikes me as highly unlikely to solve the problem.

[sparky4309]

Uwe,

Thanks for your reply, my only concern is the fact that i recently drove 300 miles with no errors? Then the next journey i turn the key and the lights stay on!!

I cant find any way of solving this problem!! I can only be open to ideas!!

Just dont want to spend over£1k for the problem not to be solved by SEAT!!!

Does anyone know why the ABS light is on yet the ABS works fine?

Any ideas?

Thanks in advance

Teves 20 ABS modules have a long history of dodgy behavior and throwning that code. It's usually the module itself that's at fault, not the pump.

The ABS light is on becuase the module detected an error.

The ABS works because the error was not detected at the time you scanned it (and probably not during that cycle of the ignition key). This is indicated by the fact that the code is shown as "Intermittent".

Once they start with this stuff, it tends to become more and more frequent. Unfortunately, the only proper fix I'm aware of is to replace the module.
