While I had it in bits I've also checked the vac lines and one way valves etc and pressure tested the dump valves as these are 14 years old now, may as well while they are all exposed.
Leading evidence: 'Check vac lines and one way valves etc and pressure' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'wee bit of removeing items will be required' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Check vac lines and one way valves etc and pressure' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

When I did mine above I cut the spade connectors off and fitted some ring crimps and bolted them on which I think is a much better way of doing it!

Suggestion
I removed the dump valves as a unit complete with the f pipe and pipe below them, this was quite tricky as the springloaded clips are not the easiest things to get off, you also have to disconnect the vac lines etc so worth taking pics to make sure they go back correctly.

Suggestion
It's worth removing and replacing/waggling the connectors first to see if that cures it.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Outcome without a verified action link
This gave better access but still not great and I still couldn't get it undone.
My oil pressure gauge sometimes works sometimes doesn't I have bought a new sensor can anyone put a pic or describe for me what's involved in replacing my old one? I am presuming the old one is on its way out?
The sender is the most obvious and something i would certainly start by replaceing .
Its not straight forward though .. unlike the non turbos its not on the cam cover but on the oil filter houseing .
Im afraid ive not done one in many a year so cant remember whats involved .. but i suspect a wee bit of removeing items will be required .

I'm replacing my sender at the moment.
I started by trying to get it from the right side of the oil filter housing by removing the y pipe and the throttle body. This allowed me to get a spanner on it but I couldn't get it undone as I couldn't get a spanner on the mounting bracket below, and the bracket just started to bend.
Next I tried getting it from the left side of the filter housing, I was still trying to do the job without removing the housing at this point as I imagined loads of oil going everywhere. I removed the dump valves as a unit complete with the f pipe and pipe below them, this was quite tricky as the springloaded clips are not the easiest things to get off, you also have to disconnect the vac lines etc so worth taking pics to make sure they go back correctly.
This gave better access but still not great and I still couldn't get it undone. What this did do was give easy access to the three bolts which hold the filter housing so I put loads of paper towel all around it then removed the housing.
To my surprise there was no oil in it at all, it must've all drained back into the sump. With the filter housing out of the way I now had perfect access to the sender and managed to undo it, it was no wonder I was struggling earlier as it was super tight.
What I don't know is if it's possible to get to the filter housing mounting bolts with out taking all the other stuff off, if it is then that would probably be a quicker way of doing it. I personally have spent years working on cars trying to do it the quick way and have learnt with the Porsche that it's often easier to just keep removing stuff to fully expose what ever it is you're working on.
It took about an hour and a half to take apart then I imagine about the same to put back together as I've not got that far yet.
While I had it in bits I've also checked the vac lines and one way valves etc and pressure tested the dump valves as these are 14 years old now, may as well while they are all exposed.

some pics, it's pretty tight in there.
Fook me it's a pain to add pics on this forum. resize first then it puts them in the post in the wrong order and ones upside down!!!!
I know this is a really old post, but I need to tackle this job as i see my pressure warning gauge bouncing a bit. I saw this before on a non turbo and it was related to a poor engine bay earth strap. Do people think pressure switch is the first place to start?
There are two common causes, the first is the sender is worn out and needs replacing, the second is the two spade connectors corrode and start to make an intermittent contact. It's worth removing and replacing/waggling the connectors first to see if that cures it.
When I did mine above I cut the spade connectors off and fitted some ring crimps and bolted them on which I think is a much better way of doing it!
As you can see I replaced mine in 2019, when I got it out after winter this spring I noticed the guage was reading 1 bar with the ignition off, its corrected itself after a couple of drives but must be starting to go dodgy again!
And nowt wrong with it being an old thread, the info is still current, and as a lot of people round here keep their cars a long time I wouldn't even call it an old thread
Thanks for the advice. I am wondering if this is something i can do myself. Im an experienced diyer but read i need to lower the engine a bit down to the bottom of the threads of the engine mounts do get to it. Having seen the tiny gap i cant see how else to get in there even to wiggle the wires. I also read about removing the the filter housing. Im just a bit nervous about it. New car first job etc.
Thanks Chris
