Hi, had the same issues a month back but i was hoping it was causing my 'Anti-pollution' fault as well. Called 2 Rad Repair companies all who said yes they could do it but once they saw it said no to a repair. The 3rd one said yes however, once he found where it was leaking from said it was unrepairable so he got a new Valeo unit for £107 + VAT. The original was Valeo also so quite pleased with price. Did not notice any improvement with the car nor did it help with the dreaded ESP/Anti-pollution fault!!!
