On-board (Trip) Computer problems. Can a fault in this computer prevent the the engine from starting or running with out giving the signals described in the Owner's Handbook?
Also - my car is right hand drive (I'm in New Zealand) and the instructions in my workshop manual for removing the On-board Computer does not apply as it is in an opposited handed position. Can some one tell me what has to be done to get it out please? Isaac.

AFAIK, a bad OBC shouldn't prevent the car from running.

antose9 is an unknown quantity at this point
No way on Board Computer malfunctioning can cause engine troubles. It just reads data, it does not control anything, so i dont believe its a cause.,... Also RHD and LHD are almost identical, just read a manual against a mirror, and you will get clear instructions

Thank you antose9. Unfortunealetly life is not always so straight forward.

The on-board computer has an anti-thief function activated by a code so if there is an attempt to start the engine the book says a gong sounds - and there may well be an immobilser function. So maybe the computer can affect other functions. You see each bank of the V has its own system so the engine should always start and run on one bank - unless there are two faults at the same time - unlikely - or a fault in a common function - i.e. this computer?

My Workshop Manual is for a left hand drive car and shows the computer on the right hand side of the radio. So with the radio removed there is easy access to the release lever in the right side of the radio opening. In my right hand drive car the computer is on the left of the radio and there is no release lever there. On the left of the computer where the release lever is located I have the "wood" trim that runs from the computer to the outside of the car. AND - without a lot of work it seems really hard to get access.

So I still need help please. Isaac.
