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.

Surely we need to change the formula from 14,400 to 9000 for miles?

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.

10 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

POST 1 / ORIGINAL POSTEROriginal post

Hi, In order to track my own maintenance and to establish when work was done prior to my ownership and to track it going forward , I took the maintenance schedule out of the Owner's manual and service manual and put it into excel. I then re arranged some of the tasks and intervals to reflect the age, yearly mileage/KM and driving that I do. If I ever come to sell the car, I will have a very quick reference for any buyer. I have attached it for general use. Maybe when I buy my next one - one of you will hand me one to demonstrate the maintenance history! Instructions – Enter the current mileage of the car and the date. Only the green cells need an input. all others are automatic. Enter the most recent date and mileage that a task was performed into the green cells of each row. If the task is over due, the mileage or date in the Next Due column will turn red. I have hidden some tasks which were duplicated or that don't apply to my car (e.g. cabriolet tasks don't apply to me) such as row 8, row 27 etc. feel free to amend the sheet to suit your car and driving. I have similar for the 987/997 but it isn't fully checked. But happy to provide it too if anyone wants it. I'm sure either can be tweaked to suit any model Porsche or car. I also add the major items I perform on the car - e.g. new dampers etc. Some of you might find it helpful. Just add a thumbs up if you download and find it useful. Note - I had to convert from xlsx to xls for it to upload to this thread. If there is any loss in functionality, let me know. Regards Padraig

POST 3 / ORIGINAL POSTEROriginal post

forgot to say - the next due column turns orange if a task is getting close, but not overdue. I think it is within a month or 1000 miles/km. There is a version in MILE and a version in KM above. The MILES version is obvious from the title.

POST 5Original post

Surely we need to change the formula from 14,400 to 9000 for miles? Or am I just stupid?

POST 6 / ORIGINAL POSTEROriginal post

That is true yes! I will edit the post. Thanks

POST 7 / ORIGINAL POSTEROriginal post

Version in miles added above :thumb:
