Good luck, it's a good job that it's under warranty 12 hours labour is hugely expensive.
As HO said when I expressed interest in a Plus Four , wait a few years for the QC dept (AKA owners) to sort out the design failures or features as they are called.
Yes I agree on that point but looking further ahead into ownership I wouldn't fancy that kind of bill for a radiator failure out of warranty, you can bet your life it will be exactly the same type of radiator goes back in. thierry did allude to the fact that the mountings may be different which could tell the full story of the failure.
Having bought my 4/4 Sport new in 2009 it being launched at the time, it's not an experience I care to relive four windscreens later and various parts of bodywork and light fittings being littered all over Dartmoor as they became unglued

not impressed at all.
26,000 joyful miles once the first year was out the way though.
