READ ANSWERDoor Latch Hangs When Unlocked
Sunday 07/26/2026 | 2003 | Boxster S | Other
I recently had a left hand URO door latch installed in my 2003 Boxster S. After the door is unlocked it doesn't open when the handle is lifted. Sometimes it opens a little then catches (half lock?). Releasing the handle and lifting again, or pressing the door shut gets the latch to release. Using the key to manually lock/unlock doesn't help. Is the latch defective or is there an adjustment to be made? I am considering replacing the URO with a Porsche latch. ...

READ ANSWERDoes brake pad replacement require rotor replacement?
Saturday 07/25/2026 | 2019 | 718 Boxster | Brakes
5,000 miles ago (66,000 miles), my front brake pads measured 4mm. So, I am expecting them to be about 3mm at my annual service next week. The Seattle North Dealer is planning to replace the rotors with the brake pads. Is this really necessary? And if it really is required to replace the rotor, why not wait until there was 1 or 2 mm? I love driving this car, but I admit not knowing much about it.This car is a daily driver that I will not track, but I want good brakes.

Friday 07/24/2026 | 2008 | Boxster | Engine
Just took my wife's Boxster to a shop for basic maintenance and was shown what appeared to be dried remnants of coolant on the bottom bracket and lower engine. Based on that they concluded that I have a coolant leak somewhere and need to drop the engine to fix it. Granted I haven't taken it on a long ride, but I have not noticed it running hot at all, even in 105 degree dessert heat. Never been to this shop before and am a bit concerned that they are not being truthful, especially ...

I am looking to restore my 1976 mod 911S Targa (aftermarket slopenose and whale tail). I am having a hard time finding a shop with real Porsche experience that can do the mechanical, interior, and paint. Paint is important, but it is my lowest priority. Everything works, but it needs a thorough restoration and the interior needs to be redone (the dash not just a reupholstery). Can anyone recommend such a shop anywhere, preferably in Texas? Anyone have experience with Einars in Houston? ...

The incandescent bulbs behind the three LCD data instruments are good and working, as are all the indicator and warning lights in the instrument cluster. However, the needle speedo, tachometer, temperature gauge, fuel gauge, every button on the center dash, and the dimmable lighting in ...
