Okey, yeah that's just to long, BTW, I bought my car i Malmö, great 7 hour drive home:P

I havn't measured any of mine coil packs, but from what I've read, you are supposed to measure betwine the pins were the cable connects.

After doing a bit of searching on the web, I must say it sounds a lot like the balance shaft belt.

From what I can read it should be about a $800 job, to get fixed, which is not as bad as my worst fear

Heading to the shop now and expecting to be taking the train home, as there is a 14 days wait at the shop.

So, 3 hours later and not any wiser.

They weren't able to determine what what wrong but didn't think it was likely to be the balance shaft. (not sure I agree).

They would like to replace the Air-Mass-meter (guess thats what it is called? In swedish it's luftmassemäter) as that was their best guess at the moment. They couldn't get one at the moment though, so it will have to wait. Also it is approx. $320-$350 for the unit and then the labour adds to it.

The mechanic could see however that the belt was moving a little in and out, so I decided to shoot a video of it, hoping that someone in here could use it for something. Though it is virtual impossible to see the belt moving in and out, it did capture the odd ticking that has been accompanied with the problem.

YouTube video

So, do you guys still think it is likely to be the belt or could they have a point in the air-mass-meter?

Also, if it is the belt, is it safe to drive the car, if you don't push it? Like max 2000 RPMs and no hard accelerations?

Is this "as bad as it gets" or is there a chance of something failing completely causing havoc to the engine?

Is there any chance for fixing it myself (with the aid of an uncle who used to be a mechanic) or does it require special skills and tools?

If it's the Mass Air Flow sensor(MAF, Luftmassemätare) that's the problem, you could buy one at mekonomen for 1584 kr, and change it yourself, takes 5 minutes, Torx25 and a wrench.

But if it was the Mass Air Flow sensor wouldn't it more like make the engine stutter, rather than making it louder and shaky? I mean, I'm all for trying replacing the sensor if there's the slightest chance it may cure the problem, it just seems odd to me, that a problem with the sensor would express itself in that way...

But then again, what do I know?

Went out the check my belt, mine seems to shake about the same.

Can't really give you a good answer to whether the MAF could do that or not, the MAF if a strange thing, if it's slightly of, it could cause the car to run strange.

You could try to clean the MAF, CRC makes a product called MAF Cleaner, works great, just remove the MAF and carefully spray the wire inside, I do that every 10000 km when I clean my K&N open air filter.

Was really hooked on the cleaning/replacing MAF idea. Until I started it this morning...

From inside the cabin it sounded like something was misfiring or overfiring (like a spark) and was instantaneously thinking "Yes! Coilpack!". But when I opened the hood it actually sounded more like something is loose and rattling inside the engine and it was rather loud.

So I decided to leave it at home and take 2 busses to the train instead.

When I get home tonight I'll try and shoot a video of it. Maybe someone can make something of it.

When my Cam adjuster cloged up, it was drivable, but had a rattle at idle and performed bad at low RPMs, could it be the same?

Has the garage run any fault codes yet. If it was a coilpack it would read as a misfire on a certain cylinder. It's always easy to check them as you can switch between cylinders and see if the problem moves to a different cylinder.

Again a fault code would show if the air mass meter was at fault.

To me it has all the symptoms of and is most likely to be the balancer shaft belt which will not trigger any fault codes. It involves putting the front end into service mode and a specialist tool to undo the bolt that allows the belt to be changed.

How is your water temp?? If that's okay then you can hopefully rule out your water pump.
