Low pressure cylinder 2

[Siman]

I’ve got a really great A3, 2013, 68,000 miles.

The previous garage changed the coil packs and spark plugs, then noticed that cylinder 2 was low pressure psi. 
It’s not their field, but go to specialists. 
 

Told the recommended specialists and straight away said it’s the valves- £2k. 
is it definitely this? Or should I sticc c I with their prognosis? 
Help pleeease 😵‍💫

I'd recommend you get a second opinion.

That’s a lot of money to remove a cylinder head. 

Any reason why you can’t complete your profile Siman?
