During a regular test of the HEVAC system and running the blowers/distribution/blend motors through their paces I just felt a barely perceptible dampness down by the lower blower output an the drivers side and, yes, it's hardly anything but definitely the start of the O ring problem! Been replaced once before in 2009. I'm not going to do the 'replace the matrix job' but what are the best replacement O rings to get (and what to avoid), what size and where from? I'd like to get some that will last another nearly 13 years like the last ones (which I can't find the detail of!).

Vehicle seems to be running absolutely fine with no warning lights or messages but I noticed the exhaust getting a bit black of late and thought it might be running a bit too rich. Plugging in the Nanocom reveals that it is throwing codes P0135 and P0155 which seems to indicate that the upstream O2 sensor heating circuits have both probably gone AWOL (one may have gone AWOL before the other without me really noticing). They seem to be on separate circuits form a common fuse - fuse is OK but one of the sensors appears to be fixed at 4V and the other one is dancing around somewhat. Before I go and order a couple of new O2 sensors can anyone:

a) Confirm my diagnosis or is there something else that could be causing the problem?
b) Recommend makes of sensor to go for (and ones to avoid)?

I have a slight problem in that my indicator stalk, when self cancelling after a turn, cancels but then continues on to start indicating the opposite way - it shoots through the centre position. Now it only does this when the ambient temperature is cool/cold. During the summer it doesn’t do it but now we are entering Autumn it’s started doing it again. Is this a common problem with an easy fix or should I start looking for a replacement stalk?

What's the secret?

I have my own web site space which I've pointed to but the pictures are not showing?

My air compressor is very old and has been ‘rebuilt’ a number of times but has now become noisy particularly for the last 20 seconds or so before cut off when, I assume, the back pressure is high and working the bearings etc quite hard. I have just rebuilt the valve block and there are no leaks in the system - it will not drop at all if left on any height setting when parked up for days. It rise and falls as expected when running, does not ‘dance’ when at a standstill, levels it self when parked and holds station nicely. NanoCom reports no faults and all height sensor readings appear OK.

However, due to the compressor being noisy I have become aware of when it operates and shuts off in normal driving and when travelling at a constant height i.e. when not having to transit between ‘normal’ and ‘motorway’ modes, the compressor operates regularly (every one or two minutes) for very short periods of time for between 10 & 20 seconds as if it is just topping up a very small drop in tank pressure. Is this normal behaviour/duty cycle?

I have managed to acquire a GROM BT-3 unit but understand that it needs a RVRN2 cable to work with the Alpine HU of a 2001 Vogue. GROM do not seem to do this cable anymore! Therefore does anyone have the detail of this cable (connector pin to pin info) so I can make one up?
