Hey, I had similar problems with my 2006 Saab a few hours ago. It was struggling to start, then when it did start it only idled for a few seconds then cut out. The third time it idled but when the throttle is pressed it did not rev. So I left it running for 5 minutes and there was smoke coming from the engine bay but when I gave it a rev it sprung into life and the smoke disappeared. Before it revved it sounded like it was chugging, sort of when a 4 cylinder is only running on 3 cylinders. It's just ticked over 186000 miles, I'm guessing egr but I might be wrong. Hope you got yours sorted buddy. Thanks for the upload 👍👍

I would start by measuring voltage and grounds at the glow plugs module

Useful video visually .. not sure why you have laced it with Ibiza beach music over your speech?

Have you checked the starter motor? It might be loose or faulty?

Next time you pull the egr, the map sensor can easily be cleaned, 1 bolt, it's just behind it on the manifold. My 93 had a slight exhaust leak at the flexy pipe, because it was b4 the oxygen sensor it intermittently played fck with my idle, probably adding fuel to compensate for unmetered air. How's the car these days? I'm on 180k atm

How different did the garage look back then? Lol

Ive seen codes for the ECU and other stuff, and he suggested EGR !!

Definitely wasn't the EGR, I tested the glow plugs by hot-wiring them and it started instantly so it's definitely a fault on the glow plug circuit

Get some Mr Muscle oven clean and spay in .Allow to sit for a hour then wash out with clean water .let dry the do again if needed .Works a treat .

Also get a restriction plate and fit to the Egr 8 mm whole in it stops the inlet manifold blocking up .Also clean the Map sensor along the top of the rail to the left of egr.one torx screw put off and clean with carb cleaner spay don't touch it .Let dry put back

Iv had a glow plug gone in my van for 5 yrs. Its slow to start on cold days but only if very cold like winter time. Even then its nothing like as bad as your sick saab.

Do you not need to depress the clutch and brake pedal before ignition. I'm having somewhat similar starting issue recently and trying to whittle down possible solution.

No my car isn't new enough to need the brake depressing before ignition. In the end this problem was a combination of my starter motor being old and worn out, which I replaced, and I also had a broken wire terminal on the front left of the car underneath where the fog lights are which I found out was part of the exterior temperature sensor circuit. Basically my car didn't know what temperature it was so it wasn't turning my glow plugs on, after fixing this it worked perfectly. I knew it had to be a glow plug related issue because it only started to be problematic when it got cold. I hope this helps, any questions feel free and I'll do my best to help out.

What millage had your car done when this problem started? How many miles have you owned this saab and has this been the only major issue?

My car is on 176,000 miles so I think it's been doing pretty well considering. The only other major problem I had was the alternator going on it about 2 or 3 years ago. And if I remember right it was on about 120,000 miles when I got it.

Hello good day. I have the same problem as you. I have a hard time starting the car when I haven't started it for hours. I have changed a heater and the battery but it still struggles. did you solve the problem? and if so what was the solution? It is translated by Google translste, in case it is mistranslated. Thanks.

Put an extra thick negative cable from your battery to a clean earth on body problem solved 😊

Did you fix it ?.. if yes please tell my how you do it ...i have the same problem with 2007 9.3 saab 1.9 TID i havea lot of diagnosc from service ... like what they think ( fly wheel, starting motor and batery , one of injector ) no error at tester

So I had a broken wiring loom under my left fog lamp, it's part of the external temperature sensor circuit. My car wasn't displaying an external temperature on my dash though so unless you have that same problem then it won't be this I don't think. I am going to finish the series soon though just been busy with other things.

@@gavinfromyavin Thanks for the video. I've got the same starting issues and the same broken loom which I need to fix (no temp display). Do you know how these two issues connect from one to the other and what causes the problem? I'm just curious as to what is going on.

@gavinfromyavin

@@skyfisting So the wiring loom is for the external thermometer, basically if that is broken then the car doesn't know what the temperature is and the glow plugs are only programmed to come on below a certain temperature, I think its like 10° and below. So basically the the car is not getting the info it needs to let the glow plugs start heating the block before trying to start which is causing the starting issues.

Glow plugs stopping it start. Not Egr imo

Problem with EGR is that it is getting dirty quickly. The diesel engines needs to be driven quite long not to get the EGR valve clogged up. If a person only drives short distances the code p0400 will appear quite often :(

Yeah I've been noticing this, I mainly do short trips and every couple of months it throws a code at me. I'm finding that taking it for a blast up the motorway cures it and I won't get a code for another month or two though.

Id replace the egr valve. It's probably broken and jammed closed.

Was going to replace it at a later date, this was more diagnostics than anything. But I agree I think it's a glow plugs issue.

Check the battery earth? Mine struggles to start and has a bad earth

ya can get a new EGR valve for £25 might as well slap a new one on

So yes I found the problem, it was a wiring terminal in front of the left front wheel that had gotten damaged. It was part of the thermostat system that tells the car it's cold and that it needs to heat the engine with the glow plugs. If you have the same issue as I did you will have no temperature read out on the dashboard and you can always check to see if any wiring is damaged in that location. I hope this helps and all the best sorting your problem. 👍
