Sorry, for the late reply...
The quotes are for replacement water pump, thermostat, belt, and water grommet, inclusive of VAT and Labour.
So update...
Car went into Halfords on Monday morning. They had it all day. Picked it up at 530pm and the 'technician' said...."Nothing wrong with it fella, ran it up, everything is dry, but your car drives really well"
Got it back, vehicle is in Sport, so know how it's been driven.
Found this odd, so the next day, i put it up on my ramps, and took the undertray off. Instantly covered in the coolant, they said wasn't there. Sump is wet, hoses are wet, and bolts around the sump, have pink crust.
Hmm...Dunno what car Halfords looked at then.
Dried it off, ran it up to try & replicate the leak, and nothing could be found or seen.
Took it to work, and water is back on the undertray.
So, it's going to Power Developments in Essex next week, to be investigated, and I'll sort it myself, once I have the download on what the fault is.



Thanks Finglonga...I'll be doing exactly that. Only losing maybe 10mm of water at a time. Hoping it's a tiny pipe weep. But will probably do the full swap out, for preventative maintenance anyway.
