Hi to all.
Ive had my lovely 964 C4 for 6 years now but for the past three years I’ve been a bad owner and not driven the lovely much at all.
Things have changed now and I need help, if you don’t mind, getting her back into the shape she should be in.
Firstly I’ve handed her to a a garage I’ve known well for a very long time. They have good conections to the local Porsche garage for advice but I have agreed that I will source the parts needed as I can’t afford new from Porsche ( if they have them) and they don’t the time to trawl the internet.
Parts identified so far are,
1. Heat exchanger heating pipes. Two front and the single rear.
2. Fan housing pipe.
3. Brake servo pump
4. Rear wiper motor
5. Rubber block under fuel filler cap
6. HVAC unit.


Does anyone know if the brake servo or the HVAC unit can be refurbed.

Well it’s all exciting. Just bought new front seats and lined up a garage for a respray as some idiot keyed on side within a month of me buying her.

I do hope you an help with any advice on my resroration and hope to meet up this summer when I hope all will be complete..

Welcome Andy, Good to hear your tidying up the C4. Have you taken the C4 directly to an indie specialist (rather than some other garage with connections to a Porsche specialist)? - I would make sure you do that before going along with a handed back list. Looking at your list (in order);

1. Expensive and come as either left side or right side - not sure what you mean by two front and one rear pipe
2. Cheap - ebay, 911 breakers or Type911 (or other online parts site - Design 911, Porscheshop etc)
3. Complicated and expensive for a C4 - the C4 came with a brake boost unit (not a pneumatic brake servo like the C2) and the complex plumbing considers ABS, main ECU, 4-wheel sensor monitoring, two diff locks etc that all run from the same fluid reserviour. Need to be very specific as to 'what' and 'why' the braking system needs looking at and the root cause of any mentioned issue.
4. Personally I sold mine - rear wiper not for me and I removed the motor, a bit pointless and never used and spoils the look/lines. I used a purpose made screen bung to cap off the hole. If you still want one then one will turn up on ebay.
5. Cheap and readily available (probably cheaper from Porsche themselves)
6. Expensive minefield to trace real issue. What was said? New HVAC doesn't mean much. Is just not working at all or flap servo motors, whining fan, random CCU head unit behavior? A very complex system in the 964 relying on so many input signals (even engine oil temp). the CCU unit can be refurbed for @ £250 (assuming the CCU is the issue).

Tackle one thing at a time and in a very clear order of priority and need. Sounds like the brakes may need looking at and tbh nothing else on your list would stop you from driving and enjoying.
 
Hi mcgc0

Many thanks for your post, it helped clear up quite a bit.
Most of the small bits and pieces are on order but they were the easy part.
It appears that the brake servo is working but the Pressure sphere that keeps the pressure up is not. I have ordered a new one and have my fingers crossed.
We have been given advice on repairing the HVAC unit which I again hope works. It seems a little simple to me but will keep you informed should or should not it work.

Regards

Andy
