Brake lights must work, very important. Check for burnt pins in rear light cluster plugs. make sure large plug at rear of gearbox to main loom is in good condition and clean contacts.

Hi mate,
I have same car with dtcs on abs:
C0161-00 ABS/TCS Brake Switch Circuit Malfunction
C0131-5A pressure sensor faulty

The problem came when I changed it by donor one.
Any idea how to fix it please?
Thanks a lot ;)

Can you explain more about what you changed and why

Hi mate,
I change only hydraulic part from donor one and after that the abs gets these dtcs. Perharps it is faulty. Tomorrow I´m going to try another one.
I was learning about these dtcs and the problem looks sensor inside hydraulic part.
Thanks a lot
