Water in footwell is likely to be blocked plenum drains. Overheating could be a number of things, including a failed fan.

It could be the matrix, but it's not a common failure where blocked plenums is. Also coolant has quite a strong smell so possible, but check the plenums first.

Temp gauge problem: no it's likely to be a problem with the IPK. The information about engine temperature comes in via CAN (Bus Controller Area Network), but so does the engine RPM. So of the tacho works, its not that. There's another thread live at the moment regarding a faulty temp guage. Carry out the checks suggested in that. If the temperature reads OK in the digital display, then its the same as in that thread, a faulty instrument pack. If the digital display also shows nothing, it could be the sensor in the engine, or a wiring problem.

Depending on the year of your car 3 or 4
on the later ones the one on the drivers wing is blanked off. other three are top of passenger wing, below ECU (Engine Control Unit) below brake servo.:)
