Electrical/Software Fault

Hi Guys,

Haven't posted on here for a while but the other day was driving along and the rear brake pad light notice came on, upon further investigation it told me that in approx. 900 miles they were due for replacement (given the car has done 13,900 miles), I thought this was a bit soon, given I don't exactly brake hard etc.

But took it to the dealer, asked him to check if it was a faulty sensor and to save the parts so I could see how worn they were. Got a call in the afternoon to say the brakes and the sensor are fine but the software needed to be reset (a glitch apparently). I said ok, went back to pick the car up and this had failed and BMW are trying to do it remotely, from Germany!! So I will hear in the morning.....hopefully!

Just wanted to know if anyone had, had a similar experience? tried searching the forum but nothing came up.

Thanks

Garage List
Have not taken it to the dealer yet (I will next month for an oil change) but I have a similar problem. The service indicator for the front pads keeps rising the kilometers!! When I bought the car it indicated a front pad change in 50.000kms. Now it has risen to 90.000 kms (and I have done 16.000 kms)....it keeps rising 10K every few months!!!!

I spoke to my dealer over the phone and told me that probably it is due to a known SW problem and needs updating. Maybe it is the same as yours.

I can't help but think that this is another example of technology for technology sake.
It has some merit, however most of these systems have a problem when dust builds up and they give false readings.
You would think that checking Brake pad wear was a complex task and could only be done effectively by sensors (not)
Just by looking at the pads every few thousand ks you can decide if they have enough meat on them and if they need replacing sooner or later.
Technology, when it works well we love it, when it doesn't we hate it. Sometimes I wonder if we really need it for everything.

Maybe the car manufacturers have found that there isn't much money to be earned selling cars, so they aim for the aftermarket. By selecting technology that makes it difficult for car owners to do their own work on their cars, they have to bring it to the dealer regularly. Some brands even use the amount of unnecessary technology in their ads. Just look at Audi and their slogan "Vorsprung durch Technik"...

totally agree
I have suspected this for a long time. Ten thousand parts to go wrong after the warrantee ends.
