It appears a new ecu has solved these issues for a few people. Pick one up off ebay, they're fairly cheap. You'll need a tech2 to marry it.

The ECU was the culprit!

Since I wasn't planning to buy a new ECU (~$1K), I bought a used ECU with stage 1 tune from BSB and had my local Saab garage marry it to my 9-3. All issues went away! AND, I have ~50 more HP now! It is like having a new car. The stage 1 tuned ECU was about $465 delivered and the cost to marry it to the car was about $115. No more blue smoke, rough idle or engine light with bunch of random codes. ;ol;

Well looks like im in for the same thing new ecu ... Fml.... Car ran like crap for a few . thought i could dodge the bullet and swapped the ecu relay out .... Was good going and coming from work . on way home stopped for gas and wouldnt start up after . got blue smoke and raw fuel smell .... Lucky for me i keep my tool box in the trunk cuz i just never know with this car ... But pulled the spark plugs and they were all wet with fuel. dried them up an sat at gas station for about 10 min and finally it started ... Had only half boost and still pulling all codes for failing ecu. Got home and let car sit for 10 min and started right up with no problem this time ...so tomorrow is another day another problem just hope it starts so i can at least get to work and drop car at mechanic and see if he can do anything for me on the cheap . not looking to put too much more into this car .

New ECU for me too

I am having the exact same problem with my car as the rest of you guys with the the open injector issues. 2003 Saab 9-3 turbo with the BSR racing upgrade. I have an appointment with Bluegrass Saab in Louisville, KY on Tuesday to get a used ECU married to my car. I really like this car but it's been giving me issues since I got it but I got a hell of a deal on it less than $1k in the car and is awesome other than the open injector issue. I will post an update and let everyone know how that goes.

I have found a way to get the car started when it gets "flooded" from the
open injectors.

1st disconnect the battery cable.
2nd reconnect the battery cable.
3rd floor the accelerator pedal, I know it sounds crazy since the car was flooded but its actually the opposite, when flooring the accelerator while starting the car it actually tells the ecu to to not inject any gas to the engine so the fuel will get pumped out of the cylinders and will eventually fire, it takes a little longer to start but keep cranking after about 20 or 30 seconds it will start but keep the accelerator floored the entire time. The car will smoke till the excess fuel is burned and will run until next time it decides to act up.

UPDATE on injector circuit issue,
I had a used ECU programmed and married to my car at the Saab Dealership as I had previously posted I was going to have done and it stopped all the injector issues on the cylinders and starts up every time now but it runs rough, it died on me a couple times and it wasn't doing that before the ECU swap. It would idle rough before, half boost and would not start due to injector issues every now and then, but now I am getting a P0327 which is giving a knock sensor description on the OBD2. I could really use some help on this subject. Thanks.

I just experienced MANY (not all) of the symptoms mentioned here, two weekends ago. All of last week my car was at the indie ...... one by one, the coils, injectors, wires, connectors, turbocharger, CPS, plugs ..... you name it, they were ruled out as potential culprits. But very intermittently, cylinder #1 would run very rich, to the point gas fumes was coming out of the exhaust. He took out plug #1 and it was covered in gas. Then did a systematic swapping of plugs #2, #3 and #4 into cylinder one and each time, they came back out wet. He did this in tandem with swapping the injectors to different cylinders. Eventually we deemed the ECU was somehow telling injector #1 (whichever actual injector was in cylinder one) to stay open and choking cylinder one with fuel.

Indie found three used ECUs at a local wrecker, sent me to go pick one up. I picked the newest (2005 9-3 Aero) and best condition one they had. Brought it back to the shop, and before the day was over my car was running completely normal.

This was last Friday. I re-flashed my BCB Stg 2 back into the ECU on Saturday, did a few adaptation runs, and everything is back to normal :)

In the process I did get him to replace a brake booster vacuum pump that's been weeping for awhile.

Same here...

Codes P0245/P0246/P0201/P0202/P0203/P0204 with low power on the turbo, occasionally petrol smell, some good days and some bad days... Happening for a few months now. I've been cleaning sensors and the garage did some pinch checks and earth checks.

The ECU went away to the warranty company but they said there was nothing wrong with it... They didn't road test it but in terms of circuits I guess they feel it's not something they will replace. Would road conditions do anything to the ECU?

I'm just loathed to buy a new ECU and then the issues again! But I'm getting tired of not having the car work okay!

Sounds like I need to try it though...

My garage was saying it has to be set to my vehicle, presumably a Tech2 job.

Richard, I think if you can source a used ECU that is compatible with your 9-3X (I'm assuming a non "X" 9-3 of same year should work) then by all means do it. That's the ONLY way to know for sure, if nothing else does.

2 weeks in after its brain transplant, and my car is running as normally as it ever did before. Knock on wood !

Cleaned some sensors... 2 days okay so far...

I know I'm probably going to get the same messages or power loss in a few days, but I thought it was worth a try! Numbers 14 and 15 were pretty dirty, but 7 and 9 looked okay but kind of hard to see much. It's a slim chance, but maybe a few bad sensors and bad pressure readings set off the ECU.

Anyway, I'll see how it goes...

Lasted 5 days and just error code P0246 but not the others...

Well, that was a good 5 days of normal Turbo-ing... Then reduced power on the motorway this evening with just P0246 00 (P) as the single error code on the eSID2 dongle.

I've cleared the code and I'll see how it goes the next few days... Then I think it's ECU time if/when it goes again.

The last 5 days have been a reminder of how nice it is when it's just being a regular Saab 9-3X XWD!

Waiting for an ECU...

My garage are trying to locate a suitable ECU and hopefully it'll be fitted in January... I'll update this thread once it's fitted and tested for a few weeks...

--------

ECU update: Being fitted on Wednesday... Fingers crossed this works. The car wouldn't start today, so I followed the flooding advice above and it eventually calmed down and started. Hopefully it'll get me back towards London tomorrow on 180-mile trip...

New ECU - seems to be okay, but ....

New fresh hell is a zero fuel gauge after putting in 50 litres...

I hear the fuel sender unit (two of these on an XWD?? or just part #11 from the pic??) is the cause...

Tempted to just use a notebook and jot down the mileage each trip. Someone tell me a Mercedes is worse...

(PS - the eSID2 has paid for itself over and over since I bought it in August.)

ECU has been the #1 solution to this problem. Everywhere I have looked, more often than not, the replacement of the ECU has been it. I tried to have mine reflashed/reprogrammed but had no luck. So it's off to buy a new one.

Had the same issue on 93 2007. I had the ECU controlled and recheck one I/C inside was out. Replaced and works fine after\
