I got mine from amazon. https://www.amazon.co.uk/dp/B00OTG9KGG?

You purchase the obdeleven dongle and download the app via the play or apple store. Ideally you need the pro verion as that allows long coding to be done.

Not a great deal with the park pilot. If you have acces to, I would scan your car with either vcds or obdeleven and see what it says. I purchased obdeleven and it has been worth its weight in gold of recent.

The glow plugs will need changing. The code will tell you which one. Use genuine skoda plugs as the system on the mk3 is very sensitive to voltage. The garage who changed mine under their warranty fitted non genuine parts (NGK) They all failed within a week. They have now fitted genuine parts and all is working as it should.

The average price for wheel alignment is anywhere from £50 upto and beyond £85, depending on how many adjustments there are and what type of machine they use. Hunter is the better one. £200 is cheap so I would get that in writing. They may only charge £35 / £40 per hour so may have factored in 3hrs work. Whereas most stealers charge double that in most places.

APR, Racing Line, Revo, Superchips, Celtic Tuning, Big Fish. R Tech. There are some more but these are who most go to.

I have a friend who deals with quantum in Nottinghamshire and he always gets good reviews. As a company that is as much as I know. Most stick to the main VAG tuners that are tried and tested.

Have all the pumps been genuine VAG parts?

My guess would be the fuel pressure regulator valve. Used to happen on the early TFSi engines. Happened on mine and back then we fitted one from the RS3 which held higher pressure.

When i had my DSG serviced they updated the software. Now when i lift off the throttle, the gear disengages like it does in eco mode, only not as pronounced as on / off like in eco. It seems to have helped with economy and doesnt affect driveability either.

Same as me. Though I had a TFSi mk2 and then later a CR170 Mk2. I will wait until the mk4 has been out a while to teeth out any gremlins first.

I thought about the petrol but I dont like the FL front end and couldn't find a pre FL to my specs. I also commute quite a bit and easily get 50+mpg out of my VRS diesel, even with DSG which isnt the most economical as opposed to manual. I may switch back to petrol in the mk4 Octy VRS in a couple of years. Enjoy your new car and it looks to be very well specified 👍

Mountune do an excellent intake option. https://www.mountune52.com/products/bundle-deal-x3-induction-system-and-induction-hose

Has the car been scanned for any fault codes. Even intermittent there will be a code stored on the ecu.

Personally I wouldn't. I would always opt for an aftermarket exhaust system over a resonator delete. You get a nicer exhaust note without the drone at motorway speeds.
