2 problems with 2000 Boxster S

Hi everybody!
As it is my first post here, let me at first say Hello to all Boxster owners from Estonia!

I have 2 problems with my 2000 Boxster S (manual). Maybe somebody here has experienced the same things. If yes, please share your experience!

1. "jumping" with 1-st gear. When releasing clutch or even just going to full throttle with clutch up, something starts to "jump" in engine and acceleration is not smooth. I was suspecting shock absorbers but back wheels are not "jumpung" off the road while doing it. Another suspections are engine mountings or clutch, but my mechanic does not agree with me... He guesses that the problem is in flywheel... Any advice?

2. Problems with generator. One day battery appeared to be empty so I jump-started the car and went for a round to charge the battery. While letting the revs near "red" in one corner, suddenly "charging" light came up. It turned out, that block of diodes and voltage regulator burned down. So I had them replaced, but when accelerating with 2-nd gear, in about 5-6000 revs charging light still lights up. If letting revs down, also light goes off. Mechanic suspects that generators coil is leaking. Any advice?

Sorry if my techical terms were not accurate, my techinal english is not so good... :-(

Thanks in advance for answers,
Julge

#1 sounds like what I call "clutch judder" and I get it with one of my cars. It's probably from a worn clutch. I'm not sure if you can resurface the flywheel on the Boxster, but basically the clutch and flywheel sound like they're due for replacement or refurbishment.


From: http://wiki.answers.com/Q/What_makes_a_clutch_judder

Clutch Judder is caused by the clutch components and flywheel not meeting concentrically. The friction surfaces rub 'off centre' causing a low frequency vibration that is transmitted to the car via the engine/gearbox mountings and drive shafts. Causes can be

1) Mis-aligned clutch

2) Clutch wear/broken 'finger' springs

3) Condensation on the flywheel (usually happens on colder nights in which case judder should only last until the condensation has evaporated)

Case 1 will require the clutch to be re-aligned

Case 2 will require a new clutch

Case 3 may happen frequently on colder mornings, but judder will disappear 5 mins into driving.

Driving continuously with judder may cause damage/increase wear to engine and/or gearbox components. If judder persists take your vehicle to a garage as soon as possible.
