- Does this seem reasonable? Car needs fixing
Right I know you lot aren’t car specialists but I do know someone always seems to know something about everything….
Mrs Crispo has a BMW 118d and has said that the abs and traction control lights keep flashing up when driving along normally. Seems to judder and cut power a bit. Taken it in to local bmw specialist and they’ve run ‘diagnostic’ and the fix is apparently two new drive shafts and two new abs sensors at a price of £640!
Anyone experienced anything similar. Also if this does need doing is £650 right kind of ball park?

Have the tyre pressures been checked and the system re-set? Beemers are so bloody connected that if the DCS senses wheel slip it can activate, and the tyre pressures could be a “sign” that it’s loosing traction (if you get my drift). Check those first.

ABS rings (relatively simple)
then see if it’s a CV / axel issue.bambooMember
That is suggesting that they think there is either a fault with the abs sensor, or the abs sensor tone ring which is on the driveshaft and is what the sensor reads. It seems to me like they are throwing the kitchen sink at it, it is likely to be one sensor or one tone ring; it is unlikely that both sensors and both tone rings are faulty. I’m not sure if there is a valid reason for means that they can only change both driveshafts at a time, but if they do need to replace the driveshafts (because the tone rings are damaged), then why are they also replacing the sensors?Posted 3 years agogeoffjSubscriber
Try and get the codes read and head to the forums.
Dead simple to use and the price of one diagnostic at the local garage.

They could be changing the driveshafts because the reluctor rings are on the cv joints. These are toothed rings that rotate with the driveshaft are are ‘read’ by the abs sensor.Posted 3 years ago
These rings can corrode and/or crack which causes a bit of chaos for the car system. If it’s an automatic it also means the car doesn’t know what gear to be in as it doesn’t know how fast the wheels are turning.
I’ve just had them replaced on my XC90 but that’s 12 years old! Fairly simple to replace (rempoe the cv joint from the hub, heat the ring and put it on the cv joint – when it cools it contracts and holds firm).
Cost about £40 each (reluctorrings.com are good) + fitting (£40-60 ish).benjiSubscriber
Sounds like a code read and then just price for everything, rather than look and find out what is actually going on. Reluctor rings splitting isn’t uncommon, especially on things like Rover 25’s. Sensors can be checked with a multimeter. As above get another professional opinion, either a good specialist or a recommended independent.Posted 3 years ago
