I have just got the car back from a regas £54.
The Leak Dye shows a leak present from the Lower Pressure Pipe on the N/S Front Wing.

The estimate to replace this pipe is as follows:-
LABOUR
4.5 hours, £168, involving removal of Battery and Tray, with Fuse Box to enable access.
PARTS
A/C pipe £60, O Rings/Oil Seals £6.50, Sundries £1.75, these are on a week to 10 day back order
TOTAL
With VAT £283.50 including a free Regas.

My first reaction was BLOODY HELL, but thinking about it I don't suppose it's really that bad.
BUT, and this is the BUT, this is subject to the A/C coming apart. Apparently the problem is where the aluminum pipe connects to a cast fitting, this frequently breaks, resulting a Dash Board removal to gain access to replace the cast fitting. The labour cost is then nearly double.

However the Technician told me he often uses a leak additive from Germany which is successful in 9 out of 10 cases which costs £60, and if it works will require an annual regas.
I am going for the additive option as a first port of call, then decide what to do if it fails
What would you do? Do you think the prices seem reasonable? What is your experience of the pipe removing successfully, and have you used the leak additive.
Of course if the additive doesn't slow the leak I could always not use the CC, but that defeats the point of having it
