Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

This is for pre 2001 model' s- as long as you have the temperture probe ( front right air intake in front bumper) you can get your OPC to activate the temperture function using PST2.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Having bought a 2nd hand C4, I was disappointed to find I didn' t have the OBC option, having had it on my previous 2 Boxsters. I had the Temp Gauge, which all C4s have but not the rest of the functions. Printed off from the Boxster Board " www.986board.com" a hack, allowing all the functions of the OBC apart from the speed gong. All I needed was to purchase a spare switch, some bits and pieces and follow the instructions - Sounds easy, however I am not so clever so a mechanic friend did the rest of the work. Works great, apart from now showing how poor my fuel consumption is.

POST 3Original post

Try starting here http://www.brackenrig.net/OBC_Hack.htm Note: Charlie seems to have got this working on a C4, it is however only worked out for a Boxster - it may not work on all 996 models! Mark

POST 4Original post

If you' ve got enough time to play with the OBC you' re not driving it like you should. Buy a DELL for home and drive the Porsche. R U a man or woosss GJB

POST 5 / ORIGINAL POSTEROriginal post

The Boxster hack is the same for 996' s. This is for pre 2001 model' s- as long as you have the temperture probe ( front right air intake in front bumper) you can get your OPC to activate the temperture function using PST2. After that a copy of the hack downloaded from www.986board.com is all you need to get it to work for you.

POST 6Original post

Does anybody have any experience of a UK OPC enabling the OBC with their PST2 ? If so how much did they charge as I have just traded my BMW 740i with every gizmo you can think of for my 911 Cab and I miss knowing the outside temp etc.

POST 7 / ORIGINAL POSTEROriginal post

Sorry I have been on holiday, any OPC worth its salt would do it for nothing !! It only requires a quick flick of the PST2, however you do need the temp probe, found in the right side grill, without it it will notwork. Charlie
