You would certainly violate any warranties such as service and
manufacturing.

I would be a bit concerned with altering another's product.  Two things
could happen, you could violate some other aspect of CE, so you would need
to re-test everything, or, you could violate something in the design
itself, and how would you explain a field problem?  The liability would
rest on you either way.   "Passing" CE is such a relative term, as we all
know, and depends on many things including standards tested to, and
pass/fail criteria.

What to do?  A nasty dilemma.  My suggestion would be, if you want to make
the investment, would be to find out the source of the problem and perhaps
approach the OEM with a proposal for your purchasing a "special" unit that
has "hardened" RF immunity (or emissions, whichever is the problem)  That
way, your not accusing them of lying, just stating that your requirements
in the environment used are a bit more stringent.  Worth a try.

Good luck
