Apologies if I’m making too many threads. I posted earlier the sound my 9-3 SE was making that sounds like rod knock, but I noticed that the belt tensioner (I’m pretty sure that’s what it is) is wiggling and the knocking sound is coming from right in that area. Any confirmation on this? Could a...

Hello, I just purchased an '07 9-3 Linear (2.0t, 6MT) with close to 190k miles. Overall, I'm pretty pleased with the car and it came with a large stack of maintenance receipts and a log of every oil change (at 5k intervals) since 2010. However, it started making this ominous clicking noise that...

Hi, I've got a 9-5 Estate Manual 2.2 TiD and it has developed a concerning knock. It normally happens in higher gears but I can make it happen in all gears above 1st. If the car is slowing down and I then accelerate it makes a loud knock when the power goes to the wheels which is louder...

Occasionally, my check engine light will come on in my 2000 saab 9-5. The codes are for misfire and knock in some or all cylinders. And sometimes, a code for the crankshaft position sensor comes up. I've replaced the sensor and it still gives that code. Even with all of those codes, it runs...

Ok so I just picked up a 1999 9-3 base model (T5) and it's acting oddly when the engine is cold. I didn't notice at first (the temp gauge doesn't work) until I hooked up my Kiwi and found out that it only acts up when the engine is below operating temperature. If you get on it too hard and hit...

Howdy, In the process of diagnosing my turbo's lack of boost (base only) I plugged the wastegate actuator hose and went for a drive. I saw that I could boost to a full 10 psi (presumably more if I wanted to kill the engine), but if I boosted to anything above 7 psi or so I would hear a knock...

My daughter's 2001 9-5 V6 has just started running very rough with a very loud knocking noise. At first I thought it was the DIC because I was having an intermittent problem with the car acting as though it was dropping out a cylinder then catching itself and running fine again. This knocking...

I have a 2003 93. It is my wifes daily driver so I only heard it the other day when I borrowed it. It is making a knocking noise at idle mostly when cold but not limited to when it is cold. It will come and go at random. Does not speed up or change pitch when gas is applied. When driving down...

After 125k miles, developed a knock audible at higher engine speeds while under load. Suspected rod bearing and/or wrist pin, piston issues. A friend suggested that one could distinguish between rod bearing failure and wrist pin / piston issues by using the engine as a brake (i.e. on a...

I have a 2004 Aero that just recently incurred a persistent knocking. The knock only happens at idle in neutral and goes away if the clutch is pushed in. Sometimes if i pump the clutch a few times the knock will decrease and almost completely go away. The only change i've made recently was an...

Hi all I have a '97 900s 2.3 n/a with a manual trans. It has around 130k miles on the clock. When at full operating temp on warm days (above 75°) I've noticed I get preignition at medium throttle. There is no over run (guess that doesn't happen anyway with fuel injection) or other symptoms...

I have a SAAB 9000 CSE 1997 2.0 97,000miles. It is a DI red replaced about a year ago. I have a fault now diagnosed by garage as a knock sensor fault, I didnt think it even had a knock sensor! The fault is a little like a Crank Sensor fault I had on a Vectra a while back in that the car drives...

So i have recently purchased a 2001 Saab 9-5 knowing it had this knock. It is a consistent noise and it seems to be in the valve train below the Direct Ignition. I have replaced all of the lifters and it still made the noise, please help me. i have a recording of the noise if you want to email...

Hoping to get some insight on this one. I am noticing a singular knock which seems to be coming from the glovebox area when I step on the accelerator while the car is moving. It seems to become more pronounced as the car warms up. If I brake hard, I can get the noise to repeat itself. It seems...

I started my 2001 Saab 9-5 V6 this morning and it turns out it has a very loud knocking/sloshing sound. I had things to do so I drove it anyway. It has not decreased my performance any, which is surprising. I have a bad O2 sensor but that shouldn't cause a knock as far as I know. :x Any Ideas?

If i don't run 93 octane my 2.3t 99 will knock? why? it never was this high maintenance before. It used to run fine on 89 octane. Also is it true that the 9-5 automatic transmission has no filter?

I am new to Saabs, so I am not familiar with how they normally sound and drive. I just bought a 2001 9-5, and while it feels like it drives fine, it does have a strange noise from either within the dash or the engine. I can only hear this low grumble sound when driving. It only happens when...

There are two people looking for this information, so I will just make this writeup it's own thread to aid finding it in the future. [b] This writeup applies to replacing the main and rod bearings in any transverse-engined SAAB 4-cylinder, 9000, NG900, 9-3, and 9-5, and pretty much any other...
