Hi al,

Need a little help or advice...

Recently had my Fabia in for a new n/s/f bearing, pair of track rod ends, new lower suspension arms and bushes to the tune of £290!

After driving away from the garage (independent) i noticed that every speed bump or general bump in the road there would be a clunk from either n/s/f wheel area, or centre of car, near gearbox. This was never there before. Took it back and they said would replace link arm for free, which they did. They found no other cause for the noise, but it still happens.

Also, when I am braking, the ABS kicks in about 10mph until I either release the brakes or stop, checked the fuses as mentioned in other topics but all ok, no play in any wheel/hub and checked the sensor ring and cleaned it, but no joy.

Will get my brother to use his VCDS at the week end, see if any codes are present, but could it just be faulty bearing? Or shoddy workmanship?

Also searched for this, but nothing exact apart from reluctor rings, but couldnt see mine to check.

TIA

Craig

They probably bent the abs ring when changing the bearing, or they have damaged the sensor, its very easy done as these sensors never want to come out. It should have stored the fault if you have it scanned.

The continuing clunk sounds like a ball joint hasn't been tightened properly.

These are all I can think of, hopefully you find a solution soon. Welcome to the forum

Exactly the same happened to me, told the garage they needed a special tool to fit the bearing without breaking the sensor but they still knackard it.

Ok thanks guys.

I'm gonna go back to the garage again to give them 1 final chance - only problem is the car is nearly impossible to drive with the ABS kicking it - feels like it wont stop sometimes! Can I just pull the fuse for the ABS/TCS out when I'm driving it so I know it will stop ok?

I know which fuse it is (2 across, 3 down), the normal brakes will work ok though wont they?

Thanks,

as stated sounds like they have damaged the abs ring or sensor.

Fuse out and you 'should' have normal non abs brakes, but dash lights

Ok, so I can drive with no abs if I pull the fuse. Garage fixed the clunk which was a lose nut apparently.

Abs still goes off, garage checked the abs sensor and ring but all ok,used their obd scanner and found no faults either while stopped or when driving. He recommended going to skoda, get them to diagnose it and he'll foot the bill and fix it if its something they did which seems fair. Just strange that there shows no fault, abs light didn't come on when it activates, but does when you turn ignition!

Do you know where the nut they tightened was?

As I said in my first post, it would likely have been the ball joint nut. Mine worked loose and clunked shortly after fitting. On some occasions it won't store a fault with abs as system thinks its doing the right thing

Also is it the abs ring type? Or is it the type that's integrated into the bearing? As sometimes these ones are faulty on arrival, or easily damaged.

I'm not sure tbh. All I know is using a normal bearing push will damage the sensor, you/they need a special tool that pushes it in without putting pressure on the wrong part. Your symptoms were exactly as my were. I tried to take the fuse out (to get me there) but couldn't put up with the buzzing noise it made.

Luckily mine just beeps 3 times then keeps flashingwhile fuse is out.

They said the bolt was on the suspension strut or something like that.

They checked the abs sensor. It is a ring but apparently they managed to swap the bearing by just disconnecting the sensor and not removing it. They said they have a taper took that only pushes in on a certain area so it can't go too far and break anything.

Should the abs light come on when it activates though? My asr light does when that kicks in.

ah strut top nut, that would explain it. my abs light doesnt come on when it kicks in so thats normal. i wonder if its a loose connection on the sensor.

It could be, we've got a few VAG specialists in Hull so I'll ring a few and see if they can tell me what it is, or get them to check it anyway!

Hi guys,

Finally got my car connected to VCDS and here's what it kicked out:

17911 - Load Signal from Alternator Term. DF: Implausible Signal

P1503 - 35-10 - - - Intermittent

01316 - ABS Control Module

49-10 - No Communications - Intermittent

I'm guessing 01316 is my problem with ABS always coming on. Will check battery connections and fuses to make sure it's not them. But how much would a replacement ABS module cost, or can you get them serviced?

17911 looks like a possible cable fault which I'll have a look at the weekend, searching for it brings up disconnected cables near the gearbox so I'll check it out.

Help with the abs code is much appreciated!

Thanks

Ok, so after finally sorting the alternator load signal cable fault I reconnected to VCDS, cleared all codes and took her for a drive. Reconnected to VCDS and spat out this code:

00283 - ABS Wheel Speed Sensor; Front Left (G47)

35-00 - -

So this seems to have been hidden under the alternator fault, and would be the cause of the ABS kicking in. I'll take it back to the garage that fitted the new front left bearing for them to fix it tomorrow, no doubt they have done something which has caused this!

Also got a nice new code:

01054 - Power Supply Relay; Terminal 30 (J317)

28-00 - Short to Plus

Something to do with diesel direct injectors, but not sure if it's causing a problem, but car does seem down on performance!

Just an update, it's been a long time coming now!

Finally got everything sorted. Went the the chaps @ Autotechnica in Hull on Saturday with the above, he couldn't find anything wrong with the electrical connections or the wiring so wanted it back for a full day to strip the bearing that was installed down. They looked today and the new bearing wasn't pushed on far enough so the sensor didn't pick up the wheel speed.

All sorted now though, went on for long enough!!!

It's amazing how many monkeys there are out there!!!!!

Glad you got it sorted!

Mine did the same a few years back.....took it to a local motorsport garage with dealer spec VAG/bosch diagnostics.......spent several days and about £400 and still not fixed.........took it to the Skoda dealer......£50 and 1/2hr later told me that the reluctor rings on both of the front bearings where "skipping" so had developed dead spots............new bearings.........problem sorted.......never managed to get my money back from the local motorsport garage.....so i just badmouth his company......all the tools and no 4ecking idea how to use them!!!

Dead spots and skipping cause lots of problems below 20mph without bringing up fault codes....
