Ok, so today the lights came on yet again.
If you read the single canonical post that you were pointed to, you will find out that it is extremely common for the lights to be intermittent.
What's most likely happening is that the 7th aluminum power wire is lifting off the gold bondpad, and it's doing so based on heat, most likely. You can test with a hairdryer, for example.
Made a appointment at the BMW dealer because I'm tried of reading 18 million threads with a billion different solutions.
Somehow you missed the entire point.
There is only one single POST that you need to read.
And, at most, a single THREAD.
With 350,000 views, all the garbage you find in the other threads has been weeded out. But, if that single post is too much for you, then, by all means, the dealer is the only one for you.
But, um, er ... uh, be prepared for the price, for, if you fix it yourself, it will cost zero dollars (if you do it all yourself), to about $100 dollars if you have to replace a sensor or repair the module.
Do compare that price, of about $100, to what the dealer is going to charge you. Then rethink the effort of reading a single post on this forum.
One reoccuring problem that keeps coming up on the c110 reader, which now is updated and reading the abs module, is ICV machinecal failure.
Had you read the post, you would know the answer to this question. No sense me repeating it here.
Could this cause these lights. Guess I know for sure next week from the dealer.
While the ICV has absolutely nothing to do with your trifecta, which is intermittent, just like thousands upon thousands of trifectas, you can guess all you want.
The only thing you will know for certain is that the dealer will lighten your wallet, big time. Good luck.
Sunday I installed a used, but working ICV valve. 3 days and over 150 miles and no lights. Wierd how a faulty ICV vavle could cause the ABS?Brake/Traction lights.
I have an expression that is in other threads, which goes sort of this way:
My next door neighbor throws parts at the problem. If there are five things that can be the cause, he simply throws five parts at it. When it takes all five, he considers it the cost of fixing the problem, but, on the 20% chance that he gets the right part in the first pass, he suddenly and loudly declares himself an utter genius in automotive diagnostic procedures!
