Hello again, my ff is keeping me busy, my fault. Since the problem with the fuel guage not reading correct I thought I would try the reset procedure my problem is it will not do as it,s told when I go through the steps and after I select test19 on the right butten then press the left I get LOCK ON and then it counts up but does nothing what have I done wrong and how do I fix it

Sounds like the tests are locked I think, hence the lock on message? You have to unlock the tests..... It's years since I did this on one of my BMWs so forgive the old memory!

Bit of BMW related info here.... Should be similar...
