Calling the AS Volvo Collective - V70 ABS fault

[gadgetgricey]

Interested in a 2002 V70, but has the frequent ABS issue, warning lights.

 

Current owner has replaced the ABS module with a part number matching (he assures me) one, but the warning light is still active.

 

Can find loads of guidance/vids on how to change the module, but very little (ie nothing) on how to change the ABS pump itself.

 

Is it just a remove, refit , bleed brakes and away, or is that too much of any over simplification.

 

Any advice would be great.

 

Cheers

I could be wrong but I think bleeding them can be a bit of a game. I think the lack of back pressure causes the valves to operate which then stops you bleeding it, but they are changed routinely so there must be a system/ method for doing it.

Can't remember but is this too young to have the ABS circuit board issue? I'm sure there is an issue with some Volvos where the ABS messes about and it is due to the circuit board in the control module.

Is this the ford era of volvo’s where components were coded to the car? Your probably going to need vida/dice to clear the code.

Whats is the code that is triggering the ABS light?

To be honest. No idea.

Just seems to be a common fault with the Volvo's and replacing the module normally fixes it.

Will ask if he can read the code

Is the ABS substantially different from the previous shape V70? Me and a mate both had 97 models and both had issues with the ABS module circuit board solder joints giving up, plus the fly by wire sensor on the throttle getting dirty and throwing a fault that impacted on the ABS too.

Think so.

Selector rings and sensors are known to go bad too, it's well worth finding what the fault is before playing parts darts with these. The rings can crack, and can be checked carefully with the abs sensors pulled and slowly turn the hubs peeping through the holes for any cracks.

I think it’s a similar system to the BMW mini as I saw a link somewhere on the mini II website and it actually showed the Volvo unit.

I hear over time that solder joints need resoldering it’s not supposed to be that bad a job.

Apparently it’s plug and play on the mini but you have to get an abs unit of the same year and same model car is rule of thumb.

The problem people were saying is it’s such a common fault that if you buy a secondhand unit the chances being it will have the same problem,

Mines the same at the moment and I’ve got too look into doing mine what’s putting me off is getting underneath on a cold wet day and bleeding the brakes afterwards.
