911 Porsche Carrera DME Relay and ECU DIY

Compare CCA...(Cold Cranking Amps) for the most reserve power. Try not to settle for less than 1000 CCA...There are limited true battery manufacturers...The most popular sellers based on Value are Costco, Autozone Duralast Gold, Walmart Maxx, Interstate, and AC Delco...you can limit your search to a factory brand from your Porsche dealer or compare others at a much higher price for less performance and guarantee. All of these will more than satisfy the reserve power needs of your Carrera...Hope this helps. (For selling value, the factory battery is usually best on high value cars like yours:)

Probably anywhere from $49 to $89 on up depending on which oil change you choose, using full synthetic oil. e.g. Walmart prices.

Maybe at the dealer it's more.

you should take it to a porsche dealer for the service, and since they are far and few, whatever the closest one charges will be your best price. don't trust the car to an independant, have it done by the techs that know the car

Most auto upholstery shops can fix this - mine cost about $600 for a tinted plastic. Clear plastic was the same cost. I had mine done in Costa Mesa, CA

either the expansion tank is just cracked or there is a head gasket problem.
