Gibbo on the Wirral?

Were you like me thinking this Gibbo might be the same chap who has Gibbo's Garage in Birkenhead?

Hello, I am back. Purchased a cloned Chinese Lexia 3 and spent a ridiculous amount of time trying to load it on my
old laptop and to get it working on XP with the car. Now I am getting vast lists of ABS problems of sensors on all wheels
giving fault reports so this is pointing to a ECU ABS problem for it to be so universal?
I did respond by replacing the popular front nearside sensor but to no avail. I have done an OHMS test on them all and they are within
range.
The Lexia says I have problems with many sectors including ABS, Suspension, Injection, BSI which I have tried to reset a number of times.

Do you have anybody near Chester who can look at this please as I use this car to take patients to hospitals around the North West region
and I am at the end of my tether?

When I had BX's and Xantia's I remember some of your current contributors from a French car forum (What was it called) which was closed down a few years ago? I knew my stuff with those cars and made many contributions in that time.

[johnhuson]

Apologies I have reposted on this subject but in response to another comment. Can a Moderator please stitch them together?
Thanks.

I'm in Wirral... My Lexia is quite old but it certainly works on Mk1 and Mk2 cars.

Although the weather is against us at the moment.

Hi Paul-R, have got the Lexia working but can not see a list of fault code 'numbers' only statements that XXXX is not working or faulty.
I have 7.57 edition. If anyone needs it they are welcome to use it with the laptop. I can put updates on if you need higher versions?
I do not seem to be operating it correctly.
Your help would be appreciated, thanks Paul-R and everyone else who has contributed.
Bit cold at the moment!
Regards, John.

Select the fault and press F5 , should take you to a numbered fault description with code

Still looking like scrapping it, but have purchased a Lexia (if you local or want to travel to Chester you can use it) and have sorted out most
problems apart from;
The ABS problem from the front left wheel has got no better with a new cable and sensor. It reads 1.5 resistance on static test with multimeter. When attached to
the Lexia to read speed of all four wheels it starts correct when driving off as the other wheels but then quickly jumps to 655kph! and ABS light comes
on again. Is that a reluctor ring problem?
Are the reluctor / ABS toner rings castellated or magnetic? Can they be changed or is it a new driveshaft? They do not seem to be readily available?

Thank you.

Thank you.

The ABS sensor reads from the magnetic wheel bearing inner dust shield, rather than from a conventional castellated ring on the driveshaft (I think most modern cars have this set up).

The symptoms you report do not necessarily sound like a problem with the wheel bearing ring. Nevertheless, if it were me I would certainly whip the hub off and have a good hard look at the wheel bearing, clean the race of any brake dust, and maybe even replace the wheel bearing for certainty (to save the hassle and expense of having a new bearing pressed out of and into your existing hub you could try simply obtaining a replacement used low mileage hub from a breakers/ebay).

[johnhuson]

Thanks Sam and everyone else.......I will clean the bearing tomorrow and that clears up the reason why I am unable to find
replacement rings!

[Hell Razor5543]

I remember Malcolm Savoy telling me about a Xsara Picasso with a hairline crack in one of the magnetic rings. This was causing them problems, and it took ages to find the sodding thing!

[wurlycorner]

Given the symptoms above, I would focus on the reluctor ring, also.

[xantia_v6]

Did the original sensor have the same symptom? Just checking the likelihood that you have fitted a faulty sensor.

Hi, this was driving me nuts, and still is, so took a holiday from this nightmare; Back to it!
C5 2.2 Auto 2002. Thanks to all for your contributions. Here is the latest news;

I did replace the left hand front hub with the built in ABS/reluctor ring in the wheel bearing, and new ABS wheel sensor, and this wheel now
travels on the Lexia on test at the same speed of the others instead of 655kph! Changed ECU with correct part number and matched to car.
Unresolved problems seem to revolve around the following, or lead to these codes;

P0500 Vehicle speed sensor, not abs wheel sensor. Where is this located please on the auto box?
P0235 Turbo pressure signal to positive or open circuit or value too high.
P0402 Exhaust gas recirculation flow excessive detected.
P0403 Exhaust gas recirculation circuit malfunction. Non acknowledgement engine torque regulation
P1421 Catalyst damage but I do not believe that to be true.

Drives well but down on power. Engine, Service,ESP, and ABS lights on ( This fault will switch off but comes back on).

My logic is that if the ECU does not know what speed the sensor is giving it could give mixed messages the engine is confusing itself with.
The Lexia is showing problems of P0235 and similar as being the centre of the problems to do with recognition of 'engine' torque.
Thanks again for all your help.

[johnhuson]

Lexia has now given a fault warning about the 'Butterfly valve' what is that and where is it please?
Sounds like throttle valve area?
