Short version...

Had the car a few months and with the exception of a minor niggle with actuator rods it's been great.

Thursday evening, went with the daughter to get a little shopping, car started fine as normal but there was a slight hiccup when first pulling away leaving supermarket car park. (Same issue as I always have btw - park it in the middle of nowhere after getting fed up with being blocked in by ***** leaving me 2" to open my door. 10 mins later my car is surrounded by Zafiras with dented doors and child seats, ggrrrrr). Daughter noticed the 'misfire' too. 30 yards later, out onto main road and it cut out blocking a set of traffic lights and a zebra crossing - oh, the stares and comments were fantastic...

Fault lights - just about everyone I've heard of - beep, PTM - beep, PASM - beep, ABS. Then a few others I hadn't heard of. I waited a min, ignition back on and everything fine. Started, move forward (to a less dodgy place to stop) and it cut out again with the same routine of various faults.

After reading on here I suspected the battery even though there's been no signs of impending death (my previous Carrera showed signs with slow cranking etc). It's a Bosch S4 but unsure of age -there's no mention in the paperwork I got with the car.

So, onto the AA and this is where it becomes a comedy classic.
A nice lad turns up, asks if I've put diesel in (errr, no), pops bonnet and checks battery volts - 11.9 but that means little. He checks other various things, then decides to remove negative battery terminal, waits for a minute then reconnects. Nothing. Then alarm sounds. Loudly.

Once this stops sounding he shits the bonnet.

Oh yeah. Key not responding, no ignition lights, alarm going mental every time a door is opened and he shuts the bonnet.

3 hours have now passed. Drivers window fully down, passenger half down and the rain starts. Torrential and horizontal.

My car, my fault and my issue but I'm now getting pissed off with the world.

Give him his dues, he soaked (as are we) and on his hands and knees trying to get a live feed to the fuse box to pop the bonnet.
It won't open.

A second AA Van turns up and gives us a lift home (only 10 mins away) so I can take shopping home (luckily on the rear seats) and get my second car to return and wait for the outcome.
Second AA van leaves, I grab the keys for the Golf and........it won't start, flat battery.

So, into my daughters Ka which hasn't moved for 6 months (she's learning to drive and lessons are with the instructors car). Fires straight up. Excellent. Heat, dry and a seat to wait the outcome.

First hiccup occurred around 7PM, car dies around 7.01.
It's now 11.30PM.

Gets down to stranded P&J.
He's jacked the car up, removed inner coverings and says there is no emergency pull cord as described on google.
I spend a few mins helping him find the missing torx socket that rolled into the dark and wet.

Nothing more he can do, has to leave, recovery on the way, sorry. As it was his fault for shutting the bonnet he'd arranged for recovery to secure location then onwards to the specialist I use the next day.

Ok, ***** happens, thanks for trying.

An hour later recovery turns up. They had not been told the car was immobile, stuck in park, towing eye in the (locked and unable to open) bonnet.

So, plastic skids - drag it onto the low loader!

Oh, it 4 wheel drive? I need four skids. I only have a pair....

Wait a while and his mate turns up in second recovery van with his pair.

I'll cut all the rest of the stuff that happened for the next 90 mins to say it was a joy to see it finally being dragged onto the low loader, backwards with straps attached to something sturdy underneath (I honestly didn't want to look).

They depart and I return home around 02.30.
Up for work at 06.00.

I get a text from the AA saying delivery to speacialist arranged for 09.30. Rang the specialist to explain things and everything is fine.

4PM, car still not arrived but they'd be in contact with specialist asking secure way to get car to them. I suppose that's better than just dragging it any old way.
5PM, specialist closed, car not arrived.
Should be here Monday.

They've used plastic to secure car where glass should be.


Sorry for the long post but I have two questions for those with more insight than myself.

Actually, three questions.

1. Could this simply be a case of knackered battery and a new one will solve it all?
2. Why the hell would you close a bonnet on a disabled car when you know you need access in around 30 secs to do a full check on the battery?


And 3.
Emptied the shopping bags and wondered where are the chilled and frozen products were. Can you guess?
 
OMG what a story. :eek:

The simple answers to your questions.

1. Yes. It might not be just the battery but I wouldn't be surprised. My 996T gave up with no warning a few years ago.

2. Brain fade.

3. I think I can guess but I won't spoil the quiz for everyone else.

Good Luck. :thumb:
 
What a nightmare story!!


1/ Could be, could maybe be the alternator as well which caused the battery to drain totally.

2/ I think 99.9% of recovery guys will have no prior experience of the nuances of these cars (eg no cable frunk release etc). As a result he probably was panicking and also didn't realise what he was doing lol

3/ front trunk by any chance?

The emergency release lever is a bit touch and go, mine was pretty hard to locate in the NS arch and was also ineffective..!
 
Thanks for the replies.

I have no malice towards the AA guy (nor the recovery guys who went beyond the call of duty spending almost 2 hours trying to get the car rolling - one of them suggested the hook up point in the fuse box was freshly snapped making it impossible to get a live feed into the system. Maybe what looked like huge truck jump leads used by AA guy weren't the best choice :x ).

99% of his work was wrong fuel (with denials from vast majority of owners) or French cars over 4 years old with engine woes - his words. As said, to expect him to know every nuance of the 997 is unfair although his googling skills could do with a little refining. I tried helping until the battery in my phone died.

I'm seeing a pattern forming here...

Any suggestions for a good battery?
I've always just plumped for the Bosch option with a healthy discount from the likes of ECP but I've read of a few posts recently with S4 and S5s just giving up without warning.

The Bosch on my Golf can be excused - it's the original battery, 11 years old on a car with almost 170,000 miles on it.

The car that came through for us, the Ford Ka has a budget Lion brand fitted, not much bigger than a PP3 !!

I left the Golf on charge over night with my tender from my biker days - optimate 4 - not showing any faults when running the test routine and car fired up no problems today. I think I'll wire up the Porsche battery to the fast connections on the optimate and use it regularly going forward.

IF (and I won't have a diagnosis until next week) it's just a duff battery and a new alternator required I'll be quite happy. I'm ok spending a few hundred to save going through all this again.

And the bonnet will NEVER be closed again if I get any battery issues in the future.




Oh, and perishables in the car, tins and bottles in the frunk is my top tip of the day.

Dark horse wins the competition - message me your address and you can have the choice between soggy chicken Kiev or Mexican chicken (once the bonnet is opened natch' )
 
A very sorry tale , all i can add is what i think it might be ...

Not the battery but the power distributor pin .. it corrodes and has the effect of cutting power from the battery .. info here about it ..

With an open bonnet you can move the base of the positive lead side to side .. this often gets the car started .

Thanks for that. :thumb:

Thinking back, it does seem strange that a battery showing no signs of impending death which cranks the engine quickly suddenly just dies.

Reading numerous posts on this forum pointed to a dodgy battery - all the failure modes on the dash and then the fans kicked in at high speed a couple of times too (cold engine, engine not running). :?

Hopefully it will be delivered on Monday and diagnosed.

I'll update the thread.
 
An update and report would be much appreciated, I'm sure there are many on here who sympathise with you and the terrible luck you have had but really want to avoid it ourselves. (Nothing worse than having soggy kiev's) :eek: :wink:
 
Interim update.

Bad news.





The Kiev's are well gone.
Now renamed Chicken Chernobyl :sad:


On a lighter note there has been some progress.

The car was 'dumped' at the specialist about 5 mins before closing for the weekend, windows still open, car soaked, steering lock on, in park and unresponsive to key or any attempts to get it to respond to anything.

A couple of the lads spent ages getting into the workshop to store over the weekend, going as far as having to jack it up several times to angle it before inching it in. Hats off to them :worship:

Early diagnosis.......it's a strange one.

They tried for hours with the normal checks but car wouldn't recognise key and the steering lock wouldn't disengage - they tried a few trade secrets eventually accessing a module and recoding the key.

Success!!

Well, almost. Most systems now power up but it's lookimg very like a suspect steering rack module (the correct term escapes me). A new module should be arriving tomorrow so fingers crossed that solves the issue.

Now, as this was being explained to me a little lamp lit in the recess of my nattered mind - I actually posted a thread about it on here a coup,e of months ago.....
I had an issue, and just a one off, where the key unlocked the car but that initial turn didn't get the little click and the res light on the dash that you normally get.
On that occasion simply locking the car and leaving for 10 mins sorted it (and there's been no issies since........until that fateful Thursday last week). Perhaps that was an early sign that things weren't perfect?

I'm really hoping it is simply the steering rack/sensor/thing.

Obviously I'll update further.

The guy diagnosing and fixing this has worked for decades on all Porsche models and this is new to him too.
 
I must admit sometimes I look back fondly to the times that if the damn ignition switch had died you just took a wire from battery +ve to coil +ve, pushed it in gear and it ran. Enough to get you home anyway. If windows were open, just turn the handle and the window closes. :thumbs: Sometimes technology is just a pain you could do without, and that is from someone who works in the technology business :roll:
 
Oh, I hear you.

I work in the railway industry and the implementation of in-cab signalling is a thing to behold.

It works perfectly on the continent - of course it does, on systems designed from scratch to use it - vast swathes of this country still rely on Victorian semaphore systems!!
 
Sounds like the key ignition switch module?
I replaced mine as I was getting some weird things with certain systems not switching on and the car not always starting when it was turned to P2. Luckily it didnt need coding and was about £200 from memory. Thanks for the update, its always good to hear of things getting resolved! (well fingers crossed that sorts it)
 
I'm confused about a couple of issues with what the garage is saying .. i have some ideas but will wait till the final conclusion to see if a comment is needed :)


Steering column control unit is the closest i can think of from your comment as there is no rack one .. but i'm afraid that has nothing to do with the key recognition .

Im intrigued to be honest .. this seems a rare and unusual fault .. your garage is lucky .. i live for faults like this ..

I think i need to move further North as we just don't get interesting problems down here .

Obviously ... no offence .. i look at things from a Mechanics perspective whilst you just want your car fixed !
 
Car back today and everything sorted *

Quick rundown from the Indys perspective:

Car dumped with nothing operating.
Battery checked and ok once they'd got access to the bonnet.
Either key inserted in ignition and nothing, no initial 'click', no response to turning.
Diagnostics checked and lots of faults but the one that looked the likely culprit was no communication with the steering 'box'. New control unit ordered and fitted (an absolute bastard to get to apparently).
Now the steering lock would work but it was acting as though it didn't recognise keys.
So, both keys recoded and bingo!!

Well, ignition and instruments lights at least, alarm reacting to key fob and bonnet working correctly.
Windows still stuck down and unresponsive to buttons,still no actual ignition.

Next step (as suggested by Demort above) - pin on distribution board.
They've had experience with this and removed the highly corroded pin, tapped threads into it and pressed an 'eye' onto the original cable - a really good permanent fix.

All done, key in and it started first turn.

Then it cut out 5 minutes later with the same faults I'd had days earlier - at least now they knew exactly the sequence of events when it's happens.

Back on the diagnostics and no communication woth the DME.
Aha! Suspect no power to DME.
A quick swap with a known working DME relay and its back to perfect. Been started and stopped a few times and been on a few little run outs in their care and no problems whatsoever.

They're happy and relieved.
I'm happy and relieved.
But the way the fault occurred and the nature of it is strange - perhaps coincidence??

The power distributor pin was definitely at fault.
As was the steering control box and the DME relay but which bit caused which fault and the sequence has me (and the lads at the Indy) scratching our heads.

Hats off to Gary, Dean and the lads (not sure if I'm allowed to mention the garage name). They've spent literally days on this and at an extremely good all in price too.

*
They also managed to fit the new turbo actuator rods while waiting for other parts to arrive - a while ago they greased up the old rods after I had problems with boost and this 'sort of' cured it but still wasn't perfect. With new rods I was expecting the end of that little issue.
Well, same fault - boosts no problem until you stop in traffic or just feather the throttle for 5 mins. Then, next time you boot it there's little boost till over 3000rpm and even that seems limited to 0.4 bar. Gods knows what's going on there. I'll update the thread I started on it - hopefully someone has an idea while I find the time to get it diagnosed again....
 
First off .. excellent news .. its fixed .

Second .. please post the garage name or pm me it and i'll post it :D

Credit where it's due and faults like this are never easy so hats off there .

My rough guess .. power pin corroded has given incorrect voltage at times to different items .. relays and control units don't like this and as such that might have caused an issue or indeed broken these items .

Root cause is power pin but subsequent damage has been caused to other items because of this .

That's my guess anyways.



Not that it helps but the faults are a new one on me .. power pin and no but the other issues are so you have been a bit unlucky i feel .
