Had these 3 lights show up recently and also the run flat inidicator on my 59 plate 135i, have had a slow puncture / faulty valve for a while and used to just pump up the slow tyre and reset the run flat indicator, now that these 3 have come on I am unable to reset the run flat anymore. I don't know if driving with this rear left tyre has caused these other 3 lights to come on but I wish I'd just bought a new tyre when I first seen it.

Anyway traction control is off and hill start doesn't work and since these lights have come on if I brake while turning there's what feels like metal on metal contact or some sort of rubbing coming through the pedal, braking in a straight line has no issues.

I've got the car booked in for a diagnotic next week but from reading on the forums here it appears it could be a few things, ABS module fault, reluctor rings, ABS Sensors, guess will see what comes up with the fault codes on diagnotics.

On a side note the bmw independant is charging £81 for plugging into diagnostics, is that steep?

Yes. You can buy your own stuff for about £25 from cableshack.

£81 is steep)
Is that just for code reading?

Yes that £81 is just for plugging it into diagnotics so they can tell me what is wrong, was told that £81 was for no matter how many times it was plugged in.

What should I be paying?

What should I be paying?

About half that would be reasonable.

Twenny read my complete fault codes in less than a minute with his carly adapter.

Thanks, I think I'll cancel that indy appointment then, just tried another here in merseyside and they were £40.

Have been doing a lot of reading over these 3 lights and one potential cause / fix, the reluctor rings corroding and going oval shaped and then rubbing on the abs sensor, are they available for my 135i as well as all the posts I have read seem to be on 4 cylinder cars.

Have spoken to a mechanic today who advised it could be the above and suggested I would need to buy new driveshafts etc, my car is 59 plate with only 28000 miles, should the driveshafts be ok on that mileage and all that would be needed is new rings and sensors?

 

[marco_polo]

Some 6 pots had the rings embedded in the wheel bearings, iirc?

 

[superchip789]

Thanks marco, maybe why the mechanic seemed suprised when I said I can get rings here:

Also, my MOT expired the other day, would the 3 lights I have on mean a failure, I thought not as they are all driving aids and some cars wouldn't have them in the first place but not sure, could be a couple of weeks before I get the car fixed properly but would like to be able to get it MOT'd before then if possible.

I had similar lights on my older e90 3series have you been round and checked all brake pads as that's what had caused them on mine and had gone through the sensor.

I've not to be honest, will check them in next couple of days, wanna check the abs sensor on my rear left which is the run flat I just kept pumping up when it went flat.

 

[Orrange28]

I had theese lights after "winter fun".
Drove couple kilometers, restarted car and they were gone.

 

[0l0dom0l0]

Just wait until you get the codes read it could be anything.

Sterling angle sensor, wheel speed sensor. Dsc unit.

No point in guessing the codes will tell you what's failed.

 

[Aycee]

Any dash lights on are an MOT fail. If the systems are fitted they must work.

Ok cheers, will get MOT after warning lights fixed then.

So after buying Dcan cable and running INPA (Can't get DIS to communicate with my car) I got these error codes:

5D91 - wheel speed sensor front left extrapolation
5D93 - wheel speed sensor front left start recognition v comparison
5D90 - wheel speed sensor front left electrical faulty
5DA3 - wheel speed sensor front right start recognition v comparison
5D96 - wheel direction front left

All of them say 'error not present now, but already stored', given that it says not present now should I just clear them and see what comes back?

If they do come back is it this part that I need:

Also, the wheel speed sensor front right start recognition v comparison fault, is that a definite replacement as seems weird that the left has 4 faults and the right just has that one, what does it mean?

 

[rob180bhp]

Erase the lot for now Road test it and deal with what ever returns

Ok so took it for a spin after clearing codes and as soon as I got off the drive 5DA3 - wheel speed sensor front right start recognition v comparison has registered, says in inpa vehicle speed 3km/h, did about 10 miles seeing if the others came back but just that one.

Seen as it's given me codes for front left and right could it be the the DSC unit itself throwing random codes out or would the DSC unit have a code of it's own?

Try unplugging the abs unit and check for any water ingress ( make sure ignition is off)

Could be 2 sensors / wiring or abs unit

Could check the abs sensor resistances while the plug is disconnected
