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 suspect 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.

Suspected cause
Actually, if it was me, I'd look into replacing the diode pack because that's likely the problem, but as you have a warranty go for the genuine item.

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

So I may need a new alternator to cure my battery drain but which is the best one to go for? Should I go OPC, if so does anyone know the price? Is a regular Bosch the same as a Porsche one? Should I go new or recon? I can't find a price for a new one, only remaufactured from Design 911 or Porscheshop for around £300 for a Lucas or a Bosch. I have a warranty on the car so they should pay for the cheaper one but is it worth me making up the difference to a more pricey one?

POST 2Original post

I had mine done in Feb at an OPC - about £400 all in. Same price as I was quoted by various independents. Cheers

POST 3Original post

Porsche do an exchange unit, and I'd go for one of those if I were you. Actually, if it was me, I'd look into replacing the diode pack because that's likely the problem, but as you have a warranty go for the genuine item.

POST 4 / ORIGINAL POSTEROriginal post

Thanks guys, I would like to go genuine obviously and it sounds like the OPC is fairly competitive. I just hope it does fix the problem!
