You need to find a shop with a Porsche specific scan tool (PST II, PIWIS, Durametric) which is capable of testing each actuator individually.

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

Greetings! Recently my 1998 Boxster has shown "check engine" codes -- sometimes P1531 and other times P1530, which my mechanic says are caused by faulty camshaft adjuster solenoids. He said the codes indicated that both solenoids were bad, but was hesitant to do the job because the solenoids are roughly $900/each, and he could not guarantee that the problem isn't caused by something else -- like a bad seal or something. The mechanic (whom I trust) said that the car could be driven regardless, however I have read that this could cause engine failure. Does anyone have any advice on (1) what could be causing these engine codes, (2) places where I could find less expensive parts, or (3) whether continuing to drive could harm the engine? I don't really have $2,000 to get the job done, unfortunately. THANKS!! -- Jon

The codes indicate that either you have a wring problem going to the Vario Cam units, or the adjusters themselves are bad; but as it is unusual for both to go out at the same time, it may be a harness issue. You need to find a shop with a Porsche specific scan tool (PST II, PIWIS, Durametric) which is capable of testing each actuator individually.

Do both various cam units do essentially the same thing, so can I drive with one working?
