  1. Thanks Loren - I'll give that a try. From my (limited) understanding of this, I thought the sensors were in pairs (or is that only on certain cars). If so, how do I know from this which one's dying? Thanks again.
  2. Hi Loren Doh - sorry. 996 C4S in the UK. '02 with about 70k miles.
  3. Can anyone shed any light on ... P2096 Porsche fault code 16 - Oxygen sensor ageing Delay bank 1 Is this really likely to be an "ageing" sensor, or is this perhaps indicative of something else. Are there other things I should be checking to get further diagnostics - I've got Durametric so I can run further tests if I know what to look for. Thanks
  4. So, it's time to replace the tyres on my '02 C4S. I'm keen to get back to Michelin Pilot Sport's (or PS2 nowadays I guess), which I had on a previous Porker - I hate the "whine" from the Pirelli's. However, it looks like there isn't the "right" size combination of Pilot Sports to get the same N rating - it's either 225/40 & 285/30 N1 or 235/40 & 295/30 N2 - i.e. there isn't a 225-295 option on the same N rating. So, the question is - has anyone fitted 235's on the front of a C4S - any issues? Thanks pete S
  5. While I was cleaning my air filter earlier in my '02 C4S, I noticed a connector that comes from the same point on the wiring loom as the MAF - close to the right hand side of the air filter box which at the moment isn't connected to anything. Any ideas what it is - should it be connected to anything (all seems to be working OK).
  6. As part of general maintenance, I thought I'd check the state of my cabin/pollen filter on my '02 C4S. So, I had a look and discovered that rather than checking it's state, I discovered that it was missing! I only bought the car a few months ago, so I can go back to the dealer and have moan, but I wondered if the lack of a filter was likely to have done any harm? The AC pump is quite noisy - nothing dramatic, but a bit noisy none the less - any likely connection? If it's been missing for a while, is it likely to have done any damage? Thanks pete S
  7. I wonder if anyone's come across a similar problem to that which I've got on my '02 C4S. The A/C is noisy when the compressor's running. It sounds like a bearing's going - there's a whiring, grinding noise and it's at it worst when the engine's running down as I come up to a junction, but I also hear it when you just blip the throttle. If I turn off the A/C, it stops right away. The wierd thing is that my dealer has already changed the compressor and it's just the same noise. Has anyone come across anything similar - a noise from the A/C which isn't linked to low gas pressure and isn't the compressor? My dealer's a little lost at the moment - they're trying hard to find it, but they and Porsche UK haven't come up with anything other than "we'll need to have another look".
  8. My '02 C4S has a slight misfire, but the CEL isn't coming on. I can't hear anything, but at around 2,750-3000 rpm, the car just feels really flat and doesn't want to pick up. It's not always there, but most of the time it is. It shows itself most if I'm just accelerating gently - start to accelerate gently away in 2nd from a slow corner and it seems to pickup fine up until close to 3k rpm and then the acceleration slows down, before picking up again at about 3250 or so. I notice it much less if I'm accelerating hard - perhaps its still there just not as noticable. The CEL did come on a few weeks ago, and my dealer changed the MAF and the coil leads. I'm not 100% sure if this problem was there before this work (if it was, it's getting worse), but I'd be very grateful for any comments or thoughts on a possible cause.
  9. I understand that pulling the relay will make it "On" all the time, but I need to be able to turn it off as well. I live in a built up area and don't want to scare my neighbours in the morning. That's why I'm going for the PSE
  10. After much reading of this forum, there seems to be 2 different views about how to disable the cutout on the PSE - I'm about to have PSE fitted to my '02 C4S. The section in How To tells me to just cut the diode. However, some other comments suggest that doing this will occasionally require the relay to be pulled out to get the switch to work again (since apparently it gets stuck in "quiet" mode) and cutting the pink/grey wire is the better way to go. Is there a definitive agreement on which is the better option?
