Fabia vRS - ABS/Electrical Problems

[Yohan]

Evening,

Took my Fabia out for a spin today as it hadn't been used for the past week and it seems to have developed a few problems whilst sitting around doing nothing.

Symptoms

First turned it on and a warning light with steering wheels and ! showed up

When driving it the hand brake light, ABS light, and TCS light, randomly flash up and the speedo drops to 0mph before bouncing back up to whatever speed I'm travelling.

Steering wheel feels really light when on the move i.e. 60mph and really heavy when moving at slow speeds, seems more noticable when turning right.

Video

Took a video of what it does, apologies for the crap quality but it's all I had with me at the time. The fault happens near the end of the video.

Vag-Com Log

Ross-Tech wiki wasn't too helpful this time.

Thanks in advance []

Fault with a wheel speed sensor(abs sensor) or the pickup for the abs that is inside the bearing.

Your best bet would be to get a diagnostic test done to find out what side is at fault.

[MoggyTech]

Check battery and battery earth cable first. If they are OK, looks like ABS control unit faulty or wiring to the control unit.

[Phil-J]

I had a faulty bearing on my own car that caused the same problem.

[Yohan]

Thanks for the quick replies.

Is there anyway with Vag-Com to tell which side is at fault?

Plan of action tomorrow is to check the abs sensors at each wheel and give them a good clean, check the earth cable and give it a clean, and finally check the plug to the abs module.

Will report back tomorrow... it's getting dark so bloomin early now!

[Tech1e]

As moggytech has said they are not sensor faults. The ABS unit has lost signal to other control units so I would guess is loosing power. Check the fuse and connections on top of battery are ok and check earths by abs unit are sound. Failing that looks like a faulty connection in ECU plug or the ECU itself.

[Phil-J]

Thats my fault, I couldn't see half the post on my phone.

[Lew0-VRS]

Start with Battery and earth's.

[Yohan]

Right only managed to clean the 3 earths on the strut and check the ECU plugs/contacts before rain put an end to any further investigation.

The fuses on the battery are all ok.

Cleared all codes with vag-com and I've got a new one now in the engine module.

Should I start pricing up ABS controllers?

[MoggyTech]

Looks like the ABS controller is faulty, prepare for wallet shock.

[Yohan]

Well what ever the fault is, it's permanent now. Speedo didn't work from the word go this morning and also when I turn corners or brake harshly the fuel gauge drops to zero then back up to what it actually reads (3/4 full), this also causing the low fuel light to briefly appear on the dash.

I'll take all the fuses off today and have a proper look.

hi

im having the same problems with my 05 fabia vrs now exact same as you described lights comeing on and stuff did your accelerate on its own whilst droping the clutch to change gear? did you manage to solve the problem?

maybe try this topic its more about PAS issues but may help? Sounds like (water)damage to the loom? or a broken sensor?

Try posting another more detailed topic it may be picked up better by the techs on here if there not too busy?

Hi.

I have just picked up this forum.

I have a Fabia 2008.

Last week, the ABS warning light came on all of a sudden in a car park at low speed.

I stopped restarted and light went out.

Nothing for a week, then it happened again today.

Does this mean trouble?

I hope not. The starter motor was kaput the other month and it turned out that water damage to some part of the wiring loom had caused a short. More expensive than I hoped all round.

Can reluctor rings ( if that is what it is) be purchased for this model separately?

Any info gratefully received?

Hi

 

Did anyone ever sort this problem? Got the same issues myself and the same fault code. 18057 - Powertrain Data Bus: Missing Message from ABS Controller18057 - sounds expensive :(

 

Thanks
