  1. I'd associate wheel bearings with a constant noise that increases with wheel speed, and a lot of heat.
  2. You'll need a thermometer, preferably one that can stick a few inches into one of the centre vents in the dashboard. Running it with recirc on, lowest temp, low fan speed for at least 10 minutes (preferably car in the shade) should give a temperature at the vent of somewhere around 4-7 degrees (maybe lower depending on ambient temperature).
  3. In my experience this is not the case. If there's substantial water ingress, especially from the rear of the car, the dehumidification ability of the aircon is insufficient to dry out the interior. For that you would get much better results with an actual dehumidifier.
  4. Aircon only removes heat and moisture from the air, there's nothing there that will inherently remove odours unless the aircon itself is the source of the smell (e.g. bacteria forming on the evaporation coil). Some premium cars have additional components like ozone generators to keep the ventilation system clean, but not in the Prius.
  5. Only naturally-aspirated petrol engines really have useful manifold vacuum pressure for supplying the servo. It's typical for turbo diesels to have similar electric pump-driven servos (in addition to supply from the manifold) and I typically see those referred to as "servos" by non-Americans (and Haynes manuals, etc.). The electric vacuum pump is normally a separate component, but maybe it's integrated in the Prius - it's not clear to me. But I'm not sure it makes it not a servo, Americans just don't use that word in reference to braking systems and I think that's why it's named as such.
  6. My understanding is "booster" is just American English for a brake servo, and it's typical for Toyota to use American names for parts.
  7. I didn't realise the EGR system changed with the facelift, mine is a Plug-in so post-facelift but it's only done about 76k miles so far so I haven't taken a look inside yet. I also use Dipetane, an additive that's supposed to help reduce carbon build-up but I honestly have no idea if it works. I'm planning on checking out the EGR once it gets to 100k, might be a few more years at this rate :)
  8. You should run the battery life expectancy test in Dr. Prius, looking at the voltages and resistance only when the car is idle won't tell you much.
  9. The stages are the same, though one difference is the ICE could be starting from cold at any speed up to 85 km/h, though significant power output from the ICE is restricted until it's in one of the later stages (or you really floor it). Not sure how that affects EGR usage. Could it be related to the known flaws with the piston rings? These engines are known to consume oil with high mileage, and I would guess that burnt oil is getting into the EGR system? I also wonder if there's something about driving conditions in the US that are making these issues more prevalent? EGR issues and head gasket failures seem more common there. One thing is that petrol is a lower octane there, typically around 91 RON for "regular" - this could mean different pressure, exhaust temperature, etc. Of course there are different environmental conditions too. Or maybe it's just the fact that they typically drive longer distances than in Europe, and the Prius is a more popular car there...
  10. Not sure about elsewhere but there was a recall of affected BMWs in Ireland, and the dealers were impounding vehicles while they were waiting for replacement parts (some were waiting months).
  11. Also in relation to BMWs: At least the Toyota EGR systems don't catch fire :) I'd also be interested to see if the Gen 4 EGRs are more reliable, I guess they're still mostly too new for us to really know.
  12. Normally there's a switch for the reverse light connected to the gearbox or linkage in some way, though I have no idea how this is done on the Prius as the transmission is controlled electronically.
  13. On Japanese market versions of the car, that space can be occupied by an ETC (Electronic Toll Collection system) card reader. On export RHD versions of the car like yours, it is just a card holder, there is no other functionality than holding a credit card sized card. I find it useful for storing parking tickets. Its functionality is described in the manual.
  14. Well compared to a modern diesel I don't think it's so bad. EGR trouble is inevitable because of the amount of soot they make, not to mention problems with DPFs, dual mass flywheels, and so on. If you bought a Mazda diesel, you'd probably need a new engine by now :)
  15. At the end of the day, it's a deterrent. If someone really wants your cat they'll get it, as destructively as needs be. But generally they'll go for the easy targets.
