These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

I've a 996 C4 tiptronic due for an MOT soon. I've heard various things about using a single axis brake tester with the AWD system. Because its only low speed I'm assuming its fine, but can anyone else confirm that its not a problem? Or should it be done a a dual axis or through a road test instead? Thanks, Jamie

POST 2Original post

My MOT guy always does a road test as he is reluctant to use the rollers on any 4WD vehicle. That is not to say that it will do damage - but I am happy to go along with his opinion. Tony
