Hi guys!, I have a problem with my xf '04, I have the BAS ESP light on, The dealer said that is the ABS module and I need replace it, the part number is 05140827AA. somebody told me that I can buy the part and plug it by myself, do you know if there is a guide or something to do it?

Antecedents: The BAS ESP light was on some days ago but I stopped the car turned the engine off and started again, the light did not come on. The next day the light was on again to run some miles I repeated the procedure, also the light go off, same day, but in the next trip I was driving my car slowly because the traffic then all the lights was on and the engine stopped. I started it immediately and the BAS ESP light was on.

I took my xf to the dealer and the did not found anything, the scan said all was ok, so i got back my xf normally, the next day in the first trip the light was on and I took my car to the dealer with the light on, then they made the diagnostics and that seems to be a sensor in the wheel, but they took another day to certify the diagnostics, but finally they to told me about the module; 05140827AA.

I have to say that the dealer forgot to reset the maintenance program after the last service. So my doubt is; Can the module failure cause the car stop?

Any help will be appreciated. Thanks in advance.
