I would still check the area under the windscreen wipers and make sure that the drain is clear.  It's the most likely cause.

if it's not that, then you could start looking at windscreen leaks & door seal leaks.  Your car doesn't have a sunroof, does it?

Before you do anything funky have you tried having the fan on full blast for a few minutes? I've cured all manner of grating noises over the years that way ...

Yes did that, and it didn't sort it unfortunately.

Saab 9-3 Sport Saloon / Convertible / Combi (Wagon/Estate) / Turbo X / AWD (2003 on) / Water in passenger footwell - first time ever!!!

« Last post by Steve McF on 15 April 2024, 12:29:54 PM »

It was raining when I drove to work this morning, but nothing out of the ordinary - fairly usual drive to work, with the heating and fan on as it was little nippy. Umbrella was on the front passenger floor, but I hadn't used it for a couple of weeks. I leaned over to pick it up as I was contemplating using it to go from the car park to the office, and as a I moved it, the mat immediately under where it had been was freshly wet. I noticed also another freshly wet bit forward of this but under the side edge of the centre console.

First thought was rain water getting into the fan via the cabin filter housing, but as it appeared to be from the centre console side, I wondered if it was something else in that area. The water did not smell of anything.

Any thoughts on what I need to check for, esteemed fellow Saabers?

Saab 9-3 Sport Saloon / Convertible / Combi (Wagon/Estate) / Turbo X / AWD (2003 on) / Re: 93 V6 fuel pressure release.

« Last post by sgould on 14 April 2024, 11:13:28 PM »

That's my assumption, but to add a bit of confusion, SWMBO was out at her concert last night and the gauge dropped to empty again.  So either the heat of the sun has expanded the fuel, or the level sensor has failed completely.  She has been using the car, and needs it tomorrow, so it may be a while before  I can investigate further.

In the meantime the 9-5 is playing up.  Erratic starting.  Starts and misses, then stalls, try again and it'd fine.  Hopefully not the CPS, that's barely a year old.  No codes.

I'll put the investigation on hold for a few days.  As the level sensor only fails to read when the tank is over ¾ full, I planned to check a reading at the connectors behind the left hand headlamp.

Seems to indicate that one of the rheostats has dead spots at the top of the range ??

I'll put the investigation on hold for a few days.  As the level sensor only fails to read when the tank is over ¾ full, I planned to check a reading at the connectors behind the left hand headlamp.  There's a 10 pin and a 24 pin shown beside the battery.

Two things have stopped me.  Firstly I can't see any connectors where the WIS shows them.  They may have been moved as that area has the control box for the swivelling headlamps.  Secondly, the fuel in the tank was high enough yesterday evening for the gauge to show zero.  Today the level seems to have dropped a teaspoonful in refilling the rail and the gauge is reading correctly, so there's no failed circuit to find. Frustrating...

I'll just have to wait for the next tankfill.  I know that i could go and do it now, but I resent driving a six mile round trip to Tesco for two gallons. 

But a bottle of Forte wouldn't hurt.   But after messing about with the sensor yesterday evening, I cleared the code and it hasn't returned.  I can record the fuel pressure with CarScanner and save the graph.  I will try that, but it will be a bit hit and miss as it's not the car I usually drive, so it won't be monitored all the time.

I was thinking along the lines of two independent failure modes, but from you decription, but perhaps the main one is nothing more than an irregular sensor result.

From reading around, it seems that this issue does only occur at start up or shut down. Does your scanner app have a logging capability so you can "see" the DTC being thrown ?

I see where you are coming from on the injector. That could be dirt, or simply a "sticky" injector, in which case perhaps clearing the code and 1/2 tank of fuel plus Forte might just do the trick

You can get this, along with the general system cleaner for £25 on ebay

Now it's a bit warmer and my fingers are working a bit better, I will investigate the two fuel level sensors.

But the P0089 code for fuel pressure error is recurring and was happening well before the level sensor failed.

It's difficult to pin down.  The word on the forums (mainly American) is that the fuel pump is failing and that you need to drop the tank and replace the pump.  But I was dubious that it was the cause as the car ran well on full throttle without any hesitation. And has done so in the 5 years since it first occurred  At first I thought it was the sensor.  A new one seemed to fix the problem, but it returned after 6 months.  The sensor is closed off and is easily wiped clean, but actually shows no sign of any coating.

Then someone else suggested cleaning the fuel rail.  I tried that and the light went out - again for about six months.  The last time the engine light came on I cleared it without doing anything and it stayed off for several months.

I'm inclined to think that there's a short intermittent fault.  I have run a pressure test on a drive with both Tech2 and CarScanner and the pressure stays high.  It's not constant on the V6 as the pump is controlled by the ECU and varies the fuel pressure depending on demand.

Since the fuel rail cleaning seems to work, I'm thinking along the lines that there's a deposit of fine particles nearer the  far end, and maybe they break off and briefly prevent an injector closing, reducing the fuel pressure momentarily.  I would take out the rail and clean it properly, but it's quite an involved process on the V6.
