That’d a great welcome so we’re definitely off to a good start. Weather was horrendous here last night so I’ll get a good look round the car today and see how I’m fixed. Have to keep the wife happy. She goes mad when I go out to “play with th cars”. Even if I’m fixing hers😂

I have 4 young kids so times always against me but thereoalways be at least 1 wanting out for a spin.

It’s over due a service but it’s done next to nothing since the last service.
What’s people’s opinions on the airbox mod that seems to be popular? The 1 by blanking off the small resonating pipe on top off the air box?


I did mine, I don't think I noticed any difference. In fact I forgot I did it until you wrote that. Might go out and undo it just to check if I am going mad or not.

I did mine but I've switched back to the norm as my car got really loud.......but I've since noticed my cat to back box sleeves are blowing.

Once I get that sorted I may try the resonator delete again. It did seem quite boomy and no difference on performance.

I have the helmholtz resonator bypass with a BMC filter, and it does add some nice intake noise. Bit louder than stock, but not noticeable when pottering.

Right. Quick update. Checked a few things today and got out for a blast. Passenger footwell is full of water and there’s a little in round the battery. I read on another thread here about the rubber bungs clogging up below the battery. Had this problem on my seat exeo. I read I need to put the key in the first position before disconnecting the battery, is that right? And have it there to reconnect it? My friend is a cleaner so I’m getting his vacuum that sucks out the water and he has some sort of fan to dry what’s left.
I’ll get onto that when I get the kids to bed. Keeps the peace with the wife.

Is there any other common ways for water to get in?

You don't need to remove the battery to unbung the drain holes. They're at either side of it.

Ok, so, sucked the water out with the vac and have a heater in the passenger seat now.
Where I would expect the water to drain was only a bung which I managed to push down through as I was trying to take it out. Is this where the water is getting through the bulkhead?
Or is that a run off for the water? If so why would I have a bung?

Yep there's one of them at each side in the bulkhead.
They're like a rubber top hat tube. You do risk pushing them through when poking. My mechanic says Hoover them instead. I poked though and unblocked mine. They aren't very long.

Pour a bit of water down and check it comes out under the car.

Edited. Just been out and looked at mine. One in your pic is drivers side. Deffo the right thing. Let's water out.
Longer than I remember and you can end up just pushing the blockage further down the pipe.
There's another on the passenger side.

My pictures not great markup. It’s the passenger side. On the drivers side I can clearly see the top hat tube but on the passenger side it was a top hat bung about 15-20mm deep. I pushed it through when trying to get it out for a look. It’s definitely a bung and not a tube.
It’s hard to see there

I've got the resonator bypass in place at the moment and I'm going to revert back - too boomy for me.

There are 4 drains in total and will all probably need clearing.

4 in total. I’m guessing 2 below the battery then. I’ll get the battery out at some stage this week and get a proper look. Have it all dried out last night thanks to having the vacuum and drier.

2 either side of the battery and one at each end of the bulkhead.

When you say resonator bypass, do you mean a bung in the top of the air box and a silicone pipe from the box to the throttle body?
Does it really make that much difference? What air filter do you have?
I’d be interested in buying it if your taking it off

Welcome Ned!

Great choice of car you have there. Good luck with sorting the niggles out, but when you do, take it out for a blast.

Just to let you know how good they are, I will just leave this here;

Welcome to the forum. bye

Plenty of expert help around here. Look forward to hearing more thumbsup

Thanks again for the welcome. I’m finding the forum very helpful. Haven’t had much time to go through everything as there’s obviously so much. The helps always much appreciated for tips and money saving advice. I might do the air box mod but think I could make it easy enough so wouldn’t be paying the Porsche tax. Everyone seems to be using k+n or bmc which I’ve never heard of. What about the likes of piper x or ram air?

Thread here with a diagram half way down -

I can't find 4 on my car, just one each side of the battery compartment.

That’s very helpful mark. It seems I need to pour water down and check it but by the look of it, a lot of cars have the top hat missing completely. It’s possible that I couldn’t see the bend on the one on the passenger side as it’s heading towards the side of the car and that’s the angle I was looking at it meaning the pipe was actually running back towards me. I’ll see if I can fish it out or make a long pair of pliers to reach in. Not overly worried as the cars inside and really won’t do much until I’m in better shape next year.

On the plus side, I was checking my history. It has only been serviced in August so I don’t need to panic on that 1 but it was only a minor/annual service so I’m assuming oil and filter only. It has a reasonably fresh paper filter so I’ll get plugs and a fuel filter for peace of mind. I’ll maybe stick in a piper x filter here to and do the airbox mod. Probably never hear it as I have full stainless headers, cats and rear boxes already. I was given 2 standard rear boxes with the car but I’ll probably sell those on as I don’t think I’ll ever use them.
Another thing to note is I have a ticking from cold. Lasts maybe a minute on idle. Gone after that and I’m assuming it’s just a sticky tapet.

The MAF is quite sensitive to an oiled filter like K&N and can cause running issues.
