The prices for these relatively simple parts are horrendous.
I had to replace the compressor inlet/outlet pipe assembly – £300 for the part. The crimping on the pipe where the flexible joins the rigid pipe into the condenser had corroded and split.
The other pipe into the condenser was showing similar corrosion albeit less severe (this was the £430 pipe). I made an aluminium clamping block to compress the crimped section and hopefully stave off failure.
Any future problems – I’ll be giving Bee Cool a call.
I also replaced the expansion valve as part of the diagnostics – the genuine Alfa part was £198! I fitted a Vauxhall valve costing £45
