How worthwhile would it be to get the air con regas done on my 10 year old Audi TT? It's done 49,300 miles.
There are three types of a/c refrigerant. The first type is obsolete. Most cars use R134A, which costs about £50 - £60 for a regas. But there is now a new refrigerant called r1234yf, which is more prone to leaking and which costs about £250 for a regas.
