What you are doing with the grease on the rubber boot ends is correct. The last new Saab DI was pre-greased on the rubber only.

I still have a tube of silicone grease that I bought from Maplins before they stopped trading. It has a very high electrical resistance and is a perfect substitute for dielectric grease.

One common cause of apparent DI problems is the earth wire connected to the thermostat housing. It connects to one of the bolts and reconnection is often missed when a thermostat is replaced.

They do look a bit cruddy.  Do you use the same filling station? 

I have this photo of the plugs removed following a DI failure and a whole week of bad misfiring and engine lights.  I was on holiday in Italy and tried to keep the car going until I got home, but in the end it got too bad and I had to unload the boot and get the spare DI out...

I would check that the valves are still OK.

I'm a bit confused by this.  The failure mode is the belt snapping and the valves and pistons going out of synchronisation.  The piston hits the valve which transmits a high force up to the rocker, which should then break.  if it doesn't, the force is transmitted by the rocker to the camshaft.   I'm surprised because I would thing that the camshaft is not the weakest link in the chain.  I would expect the rocker arm to break first, then the valve bend, before the camshaft breaks.  But modern camshafts may be a lot weaker than I think!  The camshaft bearings will also ave taken the same force in the opposite direction.

I'm wondering if the camshaft problem was due to the belt jamming the sprockets and preventing it from turning?

Mine lived in North Devon for a while, but then that and the 9-3 have survived on nice greasy London air!!

I'm wondering what has been done to your car.  I've had various mirrors on both 9-5s and 9-3s apart and I've not had any issues with the screws seizing.

The only issues that I've encountered have been with the long legs on the painted back cover breaking.

That looks like something I'll be doing soon on one of mine.  The mirror on the passenger side is from a 2004 car...

The motor comes off in one piece with the three shiny screws.  I've never had a problem with those.  Don't try moving the face of the mirror by hand to see if it's free.  That can strip the teeth on the plastic racks that the motors drive up and down.

The motor stays in one piece.  The screws just fix it to the frame.

It's a sort of white metal/aluminium base, so you will need the correct primer.

Some people have been using "Plastidip" on some things like this.  Despite its name it comes in spray cans.  If used on its own primer, it's pretty permanent, I believe.  If used on a flat surface, it will  stick, but can be peeled off if you don't like it.

It's been used successfully for covering the chrome headlamp surrounds on the "Dame Edna" 9-5 by people who think that there's too much chrome.  It seems to work, but I have only seen the results, never used it.  One result I saw was on the chrome.  The guy didn't like the finished colour, peeled it off and tried another colour.  It seems fairly durable.  It has a semi-matt finish.

I think that "Plastikote" from Wilko is similar, but I've no experience of it.


Otherwise it's a proper paint job.

If they are folding mirrors, you can't separate the two halves.  The hinge is the big tube and I believe that it's swaged out at each end.  So unless you can "unswage and "re-swage", I would say, no.

I e never worked on the 1.9 diesel. As I understand it the rockets are supposed to break, but donít always do so. The specialist I spoke to recommended removing the head to check and rebuild. Along with the new water pump and belt, itís not a very cheap job. Around £600 to £800 depending on your garage. But also fairly straightforward DIY.

What mileage?  The belt and pump are supposed to be changed as a service item at 75,000 miles or90,000 miles depending on year. Non genuine/Gates bits tend to last much less than this interval.

A funeral car described as a new arrival!!  :D  :D

I'm not with my info at the moment, but the 2003-on mirror heads are a different shape.  They use the same glass,  as the ng9-3.

The memory seats on the 9-5 are self contained as far as the memory and adjustment is concerned.  The I-Bus connection is, I believe, only there to let the car know what is going on.  So I-Bus is for the mirror memory to get the info it needs.  There may  be some other odd bits.

The basic logic of the memory seats is that both front seats have permanent power.  It's the passenger seat that has the control relay that turns the system on via a signal wire to the TWICE which earths it (green wire from memory).  Once on, the passenger seat will work.  Theres a blue wire from pin 28(? need to check this) to the same pin on the driver's seat.  Once the blue wire is live, the memory control module in the driver's seat comes live and you can move that seat as well.  If you by-pass the

The TWICE control turns the system on when the ignition is live. Also when the front door opens, and leaves it on for 30 seconds.  Maybe more.  If you don't use this, you can just earth the green(?) wire from the passenger seat relay and the seats will be operable at any time.  Not sure if this flattens the battery.  I think not though.

I've found a picture from our old 2003 9-3.  It shows the secondary air injection pipe connection to the air filter.  It should be blanked off on your car and the pipe will be missing.

I've not heard of any motors being repaired, only kits for repairing broken pivots and rods.
