Corroded TPMS valves in Chester & North Wales

I replaced 4 TPMS (Tyre Pressure Monitoring Valves) and fitted Michelin tyres to an SL55 AMG Mercedes. Customer very happy as he was driving to Italy the following week.
I also replaced 2 severely corroded TPMS valves on a Dodge Jorney near Telfords warehouse in chester today. The car had only complete 27000 miles on a 59 plate, i was really shocked at the condition of the valves.
