Sometimes you need to keep pressing the key fob to re sync it to the car.

Personally went with B4 and Eibach Pro kit. Plenty firm enough but not too firm you lose fillings.

I went with the Bilstein B4 dampers, which are the OE version and are generally thought of as being better than the standard dampers. Springs, if you do not wish to lower it then just refit the springs you have. I opted for a set of Eibach Pro Springs. They lower the car about an inch over standard but are a much more refined ride. My wife comments how much smoother the car is and less jittery. Whilst they are off I would also fit new top mounts. I also changed the anti roll bar links too. The cheapest place I found was from Autodoc for the full set.

There is a good chance the last owner might have done some coding in that control unit. I would speak to someone who has access to odis and reflash the original coding. Odis would also do diagnostic checks and find out what the issue is. Without it it can be like shooting in the dark with these types of faults.

The ratio the speedo is out is 1% on the sites I have seen that compares tyre circumferences. I have 235 Asy 5 fitted with zero issues. I might switch to the Asy 6 225 section tyres as the rubber is less dense at 88 rather than 91 load rating. The 235 are a heavier tyre than the 225 and as such will have more rotational mass.

You can get them cleaned. Removing it means you are not covered under your insurance policy and may fail on the smoke test come mot time.

Unless you did the coolant change when the coolant is warm enough for the thermostat to open, you will not get it all out. OBDeleven and VCDS does have a bleed basic setting that activates all the pumps and gets rid of any air locks.

Yes plug 3 is the sensor plug. I would just buy a genuine plug from Skoda or somewhere like Darkside.

If it only happens when cold that would point to a glowplug issue.

Spark plugs or coil packs is where I would start. Also a leaking PCV valve can cause this sort of an issue.

R Tech are excellent mappers. I would not worry about a few bhp less as that will not translate to any different on the road performance. Really only for pub bragging to say mine has over 300bhp etc. R Tech will do you an excellent custom map and advise you of what you need to know.

Low saps, mid saps are fine for DPF. I use mid saps oil by Millers that is vw507 spec. What I was saying is that the actual amount of oil burned is negligable short term and will not clogg up quickly. A DPF should last over 100,000 miles approx if driven as they should be. So it would take a while to block up again even with short runs.

My understanding is that the soot levels will be reset once clean and the car will continue to regen every 270 miles give or take. The extra oil burnt will not make too much difference as there is only a small amount. If you think how many litres of fuel is burnt per how much oil is burnt. The oil quantity is very dilute in comparison and wouldnt make a huge impact.

A DPF is a filter and will eventually block up again. If it is blocked then it needs cleaning. No one can predict how long it takes to block up again as that will depend on driving style etc. If you do not clean it out it can lead to other damage and even a fire in extreme cases. But mostly it will just go into limp mode and prevent the engine from damaging itself.
