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.

Turn the Q7 on and on your phone, in your blutooth menu, search for paired devices, the Audi UHV should appear. Select that device. It will then ask for a code. Look in your manual for the Audi Code and enter it in your phone.

Hi, When jump starting this vehicle make sure that the Q7 is connected first, then connect to the jumper vehicle. Connect 1 lead to the positive on the Q7 and the negative to a good solid body part or engine part. This will then ensure that the vehicle will start on the jumper vehicles battery directly without going through the Q7 flat battery causing the electronics to strain.
Hope this helped.
Thanks

An 09 plate Q7 should still be in warrenty as Audi offer a three year warrenty with a limit of 60,000 miles. If your vehicle is out of warrenty Audi are also known very well for good will providing the vehicle has been serviced at an Audi dealership. Try replacing the battery in the key as this may have an effect
