Customer Question

I LIVE IN LONDON UK. I HAVE A VOLVO S60 2.0T YEAR 2001, BOUGHT FROM A VOLVO MAIN DEALER IN 2009. A FEW WEEKS AGO I HAD A FAULTY REM DIAGNOSED AND REPLACED AT VAST EXPENSE TO CURE A CHRONIC SLOW BATTERY DRAINAGE. A FEW DAYS LATER THE BATTERY DRAINED AGAIN. THE DIAGNOSIS THIS TIME WAS A FAULTY CEM. COST OF REPLACEMENT EVEN VASTER.
Q1. IS THIS KIND OF SEQUENTIAL DOUBLE WHAMMY PLAUSIBLE WITH THESE ELECTRONIC UNITS?
Q2. COULD EITHER OF THESE DIAGNOSTIC PROCEDURES HAVE MISSED SOMETHING MORE ELEMENTARY AND MUCH LESS COSTLY TO FIX?
VERY GRATEFUL FOR ANY ADVICE YOU MAY HAVE.
REGARDS,
NICK TOWERS.
