Throttle body is a new one to me. Will have to Google that one. MAF has been replaced and checked in VCDS. All the vacuum pipes replaced and no signs of vacuum leaks anywhere (tested with spraying Easy Start). Brake switch was also replaced as that was suggested somewhere. ABS sensors removed and cleaned, and tested in VCDS. I even replaced the Fuel Pressure regulator and the crankcase valve breather when I got the car serviced a couple of weeks ago.
Could it be a faulty wire somewhere, as some of the error codes come and go for no apparent reason?
