Weird ABS/PSM errros: is my ABS controller going?

[ninsei]

Hi. A couple of weeks ago the ABS/PSM lights wen on. Checked code: right front wheel sensor, implausible signal. I remove it, clean off some metal filings, put the same one back in, clear the code.=, no probs for a month. Today the ABS/PSM lights went on again: 5525 incorrect data transfer with DME. Cleared it, drove a couple of miles, slammed on the brakes to kick in ABS, works fine, no codes yet.

You must have a Tiptronic?

It is not uncommon to get the 5525 Torque transmission from the DME disturbed at times.

I think it is sometimes caused by wheel slip.

Best to wait and see if any codes return.

yes it Tiptronic, and I think the 5525 did happen after I downshifted, floored, and there was a bit of wheelspin! Thanks!
