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.

Discussions that report identifying a cause: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

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.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Hi The ABS and ABD warning lights have come on on the dashboard of my 1996 993 C4. Everything seems to be working OK, have checked the fuses and all seems fine. Any help would be appreciated as I need the car tomorrow. Thanks Percy Migration info. Legacy thread was 14644

POST 2Original post

My 993TT`s ABD and ABS light came on suddenly once and it turned out that the alternator belt had snapped. Realised this when the battery would not turn. Pretty easy to have a look at the belts and make sure everything is OK. Ronnie Migration info. Legacy thread was 14647

POST 3 / ORIGINAL POSTEROriginal post

Ronnie Have checked the belts, battery, sensors and any other wires I can see without dismantling everything and all seems OK. Everyone I speak to seems to think it will be to do with the charge (Battery / alternator) so am taking it to Autostrasse so they can check it out. Do they plug them in to a computer or is it a manual check? Andrew Migration info. Legacy thread was 14663

POST 4 / ORIGINAL POSTEROriginal post

Quick update - took the car to the garage today, they plugged in the diagnostics and identified a duff near side front sent sensor - that was the easy bit. The sensor had corroded and had to be drilled out, what should have been a ten minute job took three hours! Migration info. Legacy thread was 14902
