The rusting of the casings seems to be a factor.

Martian said:....Porsche issued a service campaign back in 2009 to lubricate them with a high temperature grease. I periodically give mine a squirt of said grease and haven't had an issue in the 42K miles of ownership.
Part no. P999.917.778.00 It's pricey though, around £60 per can!
vlad said:Still not got to the bottom of the no boost issue.
My indy kindly put it up on the ramps one lunchtime to give it a quick once over to check for the obvious (stuck actuators, rods popped off, or hoses ) - but unfortunately all looked OK.
Its booked in for a more indepth investigation in a couple of weeks.
One thought - the exhaust note has become noticably boomey since the no boost issue manifested itself.
I am running a Kline system with 100 cell cats.
Could this boominess be indicative of what the problem might be?
Desperate to get fixed ASAP as I am really missing my boost fix

chimp911 said:Sticky actuators is a fairly common problem (happened to me twice) and if it is this then a bit of high temp lubricant should free it up and off you go - a decent OPC would do this free of charge... good luck :thumb:
Sorry to hear that mate, I do hope it is a quick or at least cheap fixvlad said:Well a month on and still not resolved!
...But at least I am booked in to have it looked at next week :thumb:
Your starting point must always be to boost leak check the car - none of this silly smoke rubbish. You disconnect both turbo to intercoolers hoses - they block one side and pressure to a couple of bar. That will show you any leaks.vlad said:Well a month on and still not resolved!

........In the meantime though I thought I'd do a little investigation both on the car and on the internet.
Anyway armed with one of those £5 OBDII readers bluetoothed to mobile my phone - I see I have a fault code P1095 ?
From renntech
P1095 Mass air flow ahead of throttle valve implausible (too high)
Possible fault causes:
- Hot-film mass air flow meter faulty (battered)
- DME control module faulty (ambient pressure sensor at fault detection threshold)
Car still drives OK just gutless, boost very slow to come on, no CIL's
...So now I have a bit more information I have just taken the car out for a drive with the MAF disconnected.
I was surprised it made very little difference, still feels gutless, with MAF disconnected - no boost at all though not even the 0.4 I was getting after an eternity before with the MAF connected. Still no CIL's :?:
Then I found this thread http://www.911uk.com/viewtopic.php?t=123923
My car is mapped I have the IPD82mm plenum and TB, Y-Pipe , could it be the MAF that is the issue ?
Though why do I get half boost after an eternity with the MAF connected and none with the MAF disconnected. (The MAF when it is connected is clearly having some effect - it allows some boost to come on.
Could it be the inputs from a failing MAFcausing the ECU to be confused?
Anyway enough amatuer sleuthing, off to crack open a beer
