Exclamation Help! Catastrophic failure! Saab 9-3 2007 tdi estate

Hi, new to the forum and seeking urgent help.

Drive a 9-3 estate 2007 vector sport 150 diesel, just had some work done on it by a reputable dealer, approaching a roundabout in the rain and…engine stops, faults start appearing like it’s Christmas, traction control failure, abs failiure, power steering failiure, dashboard lit up like a Christmas tree, turn off key and retry, nothing, take key out(with difficulty) retry, nothing, lights work, windows work, all electrics seem to work but not a sausage upon turning the key except every fault code I can think off. Power steering not working, brakes very stiff, managed to get a tractor to tow me home, but I live in the middle of rural France and now haven’t got a clue. Work was done whilst in the U.K. and all seemed well for 350 miles home, four days later, kaboom. Assume it’s an electrical fault, car won’t bump start, fuel gauge goes up to full when you turn the key then descends to 0. Speedo stock at 20mph whilst being towed home, and can’t get my obd2 to connect now that I am home. Free wine and cheese offered for advice that helps Please

Try disconnecting the battery for 5 minutes and reconnect it. Maybe the computer for the car got stuck and just stopped responding. Hopefully disconnecting the battery will help out.

Not really from what I've seen here on the forum. Here in the US, we don't have the diesel version. Its only petrol.

Aw man, thats not good. You'll need to find someone with a TechII device so they can read the actual codes on the vehicle. Sorry that didn't work for you.

Buy your own tech2. That's what I did.

Any chance you have access to an OBD II scanner? It's nowhere near as comprehensive as a Tech 2, but it might tell you something. (I'm assuming an OBD II scanner works on a Euro market diesel; can't say I know for sure either way...)

Best of luck, sounds like you'll need it.

Hi, I have a scanner but can’t now get it to connect to the car, assuming this is some sort of catastrophic engine management fault

Check the battery voltage,the alternator on the diesel is weak point and could have failed..

You should get TECH2 ASAP.
With TECH2 and WIS you can read DTCs and many more.

Yesterday I fixed 9-3 TiD (my-07), which also died in middle of journey.

I believed in repair shop who had "troubleshooted" and ordered ECU (owner agreed that).
"New" ECU came from scrap yard and I went to get married in car, same fault still.
Then I did a troubleshooting myself and drove to a friend 100 km with original ECU. ECU works just fine, no errors etc. So it is wiring fault, no ECU fault.
Then yesterday I did the troubleshooting of wiring harness and found owner self made fault. Owner had changed bad battery shoes and at the same time cut off the grounding screw. Earthing of ECU and glow plugs relay had come to an end and the trip was over. So tow car to repair shop.
I made a new earthing point on the front edge of the battery case while the car is running.

Car was sitting in repair shop about 1 month before owner calls me!

ECU is worst possible place: under front bumper just front of right wheel. You find a lot of dirt on ECU and its wiring. Wirings also are routed idiot way: they make sharp ower 180 degree loop just next from connector.

I have met only 2 TiDs which have real alternator problem, all others have bad battery shoes. They corrodes internally, so only way to check corrosion is feel, bad joint gets warm, even HOT.

Thanks for all the advice, however …………

Just pulled the 30amp ecu management fuse and found it blown, replaced it and started first time, b&ll&cks, sure there is a fault, but at least I am up and running

Yes. You need also 32mB memory card, which is not included. Same seller offers that too in reasonable price.
You also need laptop which includes Global TIS. TIS is for security access etc. Without security access you can only read DTCs with your car.

the fact that it's blown means a short to ground somewhere,better stock up them as this will more than likely blow again and again..
