The MAF will cause problems in all conditions, so coil packs. Get 6 from Autodoc, BERU ZS178 is the one you need.
Any ideas? Don’t want to get the wrong ones?
-
BTW any top tips on changing them ie get engine warm first or not etc etc to help bolts come out?
Thanks once again to everyone👍

Yes, that would tend to point at old coil packs getting damp in them. When you said they were original, I assume you mean just in your ownership rather than from new😬. Mine are about 8 years old, so they’ve had a fair run.
I’ve had the car for 12ish years and never been done in my ownership so can’t grumble if they are the cause.
Interesting day ahead tomorrow! -
Ok, I cleared the fault codes this evening and then let the car idle till up to temperature then drove it up and down the drive a few times. It seemed to run fine. Checked for codes again and none stored, all clear.
I guess if it’s running fine I’m not at this point going to find anything out by unplugging the MAF sensor, so from what has happened does this tend to lead to the coil packs?I will take it out for a drive in daylight tomorrow to see if the problem reoccurs

Either 1 and 4 coil packs, at the front so most exposed to the road, or MAF. A lamdba would be only on one bank normally. I'd go with disconnect the MAF and see if it runs clean as the first step, if nothing else saves jacking up the car taking wheels off and crawling underneath! Although you do have to get the roof to service position and take the top cover off. MAF is passenger side toward the back of the side of the engine bay, check on YT video.
I will have a look tomorrow if I can.
So if I look at the coils am I understanding 1 and 4 are the front ones either side?
Thankyou

Thankyou everyone I will do as suggested when I have time and report my findings

When you clear the codes, do they come back? I think I would be letting it idle with the occasional rev to come upto temperature to help drive off the moisture and then let it cool before checking if the issue is still there before getting into removing the engine cover etc. If this solves it, then it does strongly point to coil packs. When were they last changed?
The coil packs are the original ones as far as I’m aware as is the MAF sensor

Update!
Codes read: As follows 3 stored,
1. P0300 Random / multiple cylinder misfire
2. P0301 Cylinder 1 misfire detected
3. P0304 Cylinder 4 misfire detected
Does this now point to anything obvious please ?
Thankyou

Thankyou everyone.
The engine light flashed up intermittently then stayed on. I will have a look for cracks on the coils tomorrow. Am I right in thinking the coils could still play up if not cracked?

Good evening everyone
Took boxster out for run this afternoon and out of the blue engine light started flashing and engine started running a bit rough. Nursed it home as wasn’t far. Have no code reader and certainly wouldn’t drive it anywhere as it is ? Any ideas ? Car was serviced just a few weeks ago at SCS Porsche with obviously nothing picked up. Was running perfect. Coil packs? Maf sensor?
Any thoughts?
Thankyou -
Thankyou 👍

Does anyone know what these rubber mounted fixings are called or the part number please? I’m compiling an order and might as well add.
Also the part no. of the rubber retaining clamp that runs along the underside of the sill for the air con lines ? One has split
Thankyou

Water in the lower section off the drivers floor pan behind seat during heavy rain storms
Drain holes Checked
No rips in hood
No holes in polystyrene
No rips in door polythene membrane
Not very tech but when I put my finger down the drain hole in the polystyrene water collection tray I can feel an open area & metal bodywork before the next drain hole. It’s like there’s a short section of pipe missing to join the two.l, wierd thing is it’s the same both sides passenger side seems ok
That is exactly the same as me on my drivers side. I removed the old one today to check before ordering and it is absolutely fine so just refitted. I have checked absolutely everything as well as my local Porsche specialist. If I park just slightly facing down hill or perfectly flat it’s fine, it only slightly leaks if it’s parked on a drive that tilts the car to one side, it has to be extremely heavy rain too. I’m thinking it’s just the gap between the foam tray and the tube not quite catching all the water when tilted.
Luckily it’s extremely minor but still annoying. Will be getting my local Porsche specialist to have another look when it’s in for its service soon.
Will update thread if they find anything.

Ok Thankyou
-
Fantastic Thankyou !
so it’s all one part then .
do you know if the foam tray has to be removed and fitted from the top or can it be done from underneath removing the wheel arch cover? -
Sorry no it’s the other one that’s under the foam tray .
thankyou -

Hi
does anyone have the part number for the drivers side rear roof drain pipe please. Is the plastic funnel under the foam trays connected to the pipe as one or are they separate components?
Thankyou
-
996 no brainer 👍
-
I just have a batten on the floor in my garage so I know when my back wheel hits it to stop👍
-
Sorry to hear !
Not sure of your situation but if mine ever goes bang (again) *new engine fitted back in 2008 by Exeter Porsche only 20,000 miles, I’m going all out and doing something worth doing maybe a 3.6
Look at it as an opportunity or sell it!
