Fault codes in the A/C module.

Yes, or you can replace them with proper Terry Jubilee clips.

It's dead common. The "best solution" with asymmetric but non-directional tyres is to swap all 4 diagonally (Front left with rear right and front right with rear left). Someone with a Hunter rig may help with any geometry issues but a lot of the problem is wear caused by braking and no acceleration forces on the rear axle. Also, as above the issue also occurs with hatchbacks (and indeed mks 1, 2 and 4 as well as mk3 cars).

As I'm reading this you need a different garage. One that will do a UV dye check rather than guessing.

I'm pretty much dead certain that JR is correct about it being the immobiliser. More wallet pain here I'm afraid.

That is generally but not always true. You may have caught the stem seal failure at an early stage. It requires more investigation than I can do in text. Go to a good local garage or VAG specialist, not a Skoda main stealer.

These days it seems likely true.

Are you sure it's cruise control and not a GPS assisted speed limiter?

also @Martyn91 True this, based on knowing private hire (and taxi using private car) drivers well enough to know that their expectations were 2 or 3 years battery life for Octavia and Superb 3s,

The second point only actually applies if the last registered keeper was (or at least appears to be) a private individual.

Find a decent fast fit place, and ask them to do a "deep load test" on the battery. That'll be free as long as you buy a new on from them if needed, and come in under £200 coded in.

Don't get the battery from a Skoda main stealer then!!

And, indeed, where the park pawl has slipped and the car has rolled.

Check the battery cable connections are sound, starting at the battery end, then earthing points, then solenoid and starter motor.

Ok, you want to do a minimum of work to the ride height in this case; think tarmac rally suspension rather than your gravel idea. Engine/transmission wise, if you can afford it, Felicia "kit car" spec engine, 1.6l Group A engine, 1.8t and VR6 engines have all been done before.
