Managed to do a few more things on the GTI;

Replaced the PCV, fuel filter and spark plugs all genuine parts. Does feel smoother now. Although the mechanic struggled to get the fuel lines off the old filter just hope he didn't cause any damage or leaks.

MPG wise I am getting about 30-34 on my 9 mile commute to work mix of traffic and dual carriageways. £30 of V Power (~22 litres) gave me roughly 135 miles so probably not too bad.

Next is to investigate the rear calipers and getting a whirring/booming noise which changes on different roads. I am thinking of getting the alignment done again and checking the state of the tyres.

I average about the same mpg in similar journey.
The noise is probably what they call saw tooth on the tread. Search google for more info on it. They do suffer it. Mine has in the past. An alignment helps reduce it as does rotating the tyres.

Hmm thanks for the suggestion on the tyres. It's quite an intrusive sound on some roads i.e. dual carriageways.

Few more things I would like to address in the coming weeks;

The car came with replica 18" Monzas. I have always liked the original diamond cut so keeping an eye out if a genuine set come up for sale. Would be looking at around £500+ with tyres so I was wondering if I should just get a set of 17" Monzas. I know it would improve ride quality but the trade off would be looks..

Car has Dynaudio but I believe the drivers side door speaker is on its way out. Will try to get it looked at by an audio specialist.

Door speaker could just be a loose connection. Dead easy to take the door cards out and have a look for yourself. You should get yourself plastic trim tools and a set of torx drivers. You could even fit some sound deadening material while you're in there which would increase your audio quality.

The 18" Monzas are the best thing about the Mk6. I hope you find some. Mine are kerbed and not very shiny any more, but they still look great! Better than any new GTI.

Ive got the 17s and 18s. The 17s have more bounce as the side wall compress more. If anything i feel because of that the ride is better on the 18s. Very little difference and tyre brand has made more difference.
Speaker could simple be bad connection in the door jam or speaker itself

Thanks both think I will attempt the speaker job myself just need to buy some trim removal tools.

Both exhausts were incredibly sooty so some wire wool and autosol has made them nice again but already they are starting to soot up again. I take it this is due to the direct injection system on these engines?

So just over a month ago I topped up about 0.5L oil as it was less than halfway on the dipstick. Few days ago I checked again and the level is just below halfway again. Had the car checked over by an indy and they have come back with a £270 quote to replace the breather pipe and intake rubber pipe. Seems excessive? They also mentioned the engine will require a steam clean after and then rechecked to see if the oil leak has gone. I’ve attached a photo I managed to get while the car was on the ramps. I don’t think it’s a turbo leak and the garage agree on that.

Im not sure what they want to replace.
Better to clean it first and follow the trail but that's just my way.
Id be double checking the pcv pipework before replacing anything. As you said previously it was replaced. So I would check its seal on the head as its easy to screw up. Also check pipe from rear breather pipe fitted correctly and sealing and not  dripping down.
Then check its not the cam cover gasket or the sensor on the front which are known to have a bad seal and leak round the cover and drip down the rear.
Also check the diverted valve diaphragm isn't split.
Also would be checking its not the oil freed pipe to the turbo as they are kwell known to get pin price size holes in and spray oil out.

Thanks Snoopy, great suggestions there. I just hope it isn’t the piston rings like some of the Audi TFSI engines from the time were plagued with.

Only if its burning it not leaking it.
As you had the pcv replaced check the rear crank seal isn't leaking. It's the weakest link when pressure builds.
Check the under the engine the join between the gearbox and engine. There's a ruff patch in the casting in the join. Make sure oil isn't leaking out of there.

You can clean the oil off by buying a can of brake cleaner and spraying it at the oil covered bits it will wash it off.
