Since the short answer to your question in my opinion is;
"There are no known problems as far as I can see", I thought it would
be better to explain, why I believe that there are not any problems
with the vehicle model.
Taking a less specific example, If we search "Ford Escort" and
Problems into a search, Google comes up with 2380 hits. The first few
are related to Ford Escort/Orion 1.6 and reveal known problems such as
the unstable 'Idle Speed'.
Using "Vauxhall" problems reveals hits on known issues with Astra,
Calibra and Cavelier.
In fact you can use this strategy for most vehicle manufacturers and

530","BMW 530i","BMW 530i SE" and finally "BMW 530i SE Tourer"
So as you can see, I tried every possible combination that would yield
information or news on any suspected or reported problems with this
model of vehicle.
As a final check, I did contact the local but quite large BMW
dealership's service department who said that they haven't heard of
any problems with that model.
In fact the only reference I could find was on a much older K-reg BMW
After an exhaustive search, my conclusion is that there are no known
design issues or flaws with the make and model of the vehicle that you
You may find this road test of your vehicle interesting as apart from
cramped cockpit space in comparison with the Mercedes, it would appear
