Where is 6th cylinder?

most those bolts are TTY and are not reused.
and are set by angle. not torque.
I guess you never worked modern engines, or read the service manual first for all the steps in order ?
2.0L gas?
2.0. is not any suzuki engine name at all
and there are four(4) 2.0L engine used, 2 gas and 2 diesel
we can not guess engines, is it a USA car or not? I only answer for USA.
2.0 DDIS or AWD version < my guess is SuZ J20b?
2.0L vvt and vvt-i

SM< words , USA 2.0L gas VVT ,, (2.0L VIN 5, 6th digit?)

You need the transmission control module scanned for fault codes. I know the check engine light must be coming on when this happens, correct?

You have a worn out clutch disc so the transmission still has to come out to change it.

Comparing a Skoda Kodiaq with an Audi Q7 is like comparing Rs. 25 lakhs to Rs. 80 lakhs (literally). Audi is the ultimate brand in the luxury segment while Skoda is the low-cost brand of Volkswagen.
Here are some points why Audi Q7 is better than Skoda:-
1)Audi has a great resale value, much more than that of Skoda.
2)The technology used in Audi cars about half a decade ago is now being used in the new Skodas. That is how much advanced the German company is.
If you compare them hand-on-hand, this is the result you will get.
1)Both the cars are powered by a 2.0-litre petrol engine (a diesel engine is also available in both). But what is different here is that the Audi Q7 produces 248 bhp/370 Nm of power/torque. The Skoda Kodiaq makes just 177 bhp/320 Nm of power/torque.
2)The Audi Q7 has an advanced AWD which, I am sure, you will love. The Kodiaq will have AWD only on the top spec model.
3)Audi has high-tech features including a 23 speaker audio system. You will miss that in the Skoda.
4)The Audi Q7 has 8 air bags and is equipped with almost all the safety features. The Skoda has a few of them only.
5)The Audi Q7 is better in terms of design, any day.
But then, there is one more fact that you have to mention if you are comparing a Skoda Kodiaq and an Audi Q7. The difference in price between the two is humongous, almost half a crore for the entry level variants. So if you can afford an Audi, look no further, the Skoda Kodiaq does not stand a chance here.

It sounds like the clutch is completely gone, you will need to look and see if the clutch release bearing is moving, if it is then the transmission must come out and the clutch replaced.

Not necessarily. But if the mechanic has advised you to change then do so as he is must have noticed something wrong with them.

I've seen a lot of these cars with bad coils. Try swapping around the 6th coil, to a different cylinder, to see if the misfire moves with the bad coil. That way, you can pinpoint if that coil is indeed bad.

Speed sensor light, do you mean check engine light? I'm a retired (2004) Ford dealer tech and I have no memory of any light called a speed sensor light.

Try replacing the engine temp sensor. Temp sensor is telling ECU the engine is hot when its is actually cold. After the 6th attempt there is enough fuel in the cylinders to create a ritch mixture, then it goes.
