Exactly the same problem with my Rx500h. I have never had to put any more than 45 litres in a 65 litre tank from close to empty. I always fill up before gauge shows empty. That leaves me with 20 litres  of fuel that I never get the useful distance of. Going in for 12mth service tomorrow and will see what b/s they serve up as an excuse. Surely they should be able to recalibrate the gauge!  

Hey guys I have after market Taillights and headlights. My check vsc, traction control, and emergency brake light turned on, and my right blinker and headlight work perfect. My left ones work good but my blinker blinks really fast the other side doesn’t have this problem. But when my hazard’s are on they all work fine. What do I need to do to fix these problems?

Hello all, I have just recently purchased a 2004 is200. I was wondering what modifications I can implement to increase my power output. I'm quite stuck on answers at the moment. I also wanted to ask if anyone knows if its possible to put an is300 catback onto an is200 as I cant seem to find any exhausts out there for my car.

Hello Darren, Nice to hear from you. Once the XBB Power Unit (Bluetooth Relay) is installed and the driving light/s are attached and tested, you insert The XBB dongle into the OBD2 connection. Explicit instructions come with the kit and you will need to download the app to your phone. You need to log into XBB, and will be guided through the process of selecting the make and model, and how to test it for correct function. Now Darren, I am a seventy three dinosaur, and I managed first time. Programming the 'Smart Switch was a fair bit more difficult, but I contacted the trouble-shooting section of XBB, explained what I was after, and got an instant response from the guy who invented this system. This took a while to sort out, mainly because some of the language and wording is different than what we use in Australia on computers and smart phones. In hindsight, I may not have installed the smart switch. I believe if a mechanical switch is put in between the relay output and the light/s it would do the same task, only for a much lower cost. Only problem is you need to 'mouse' a figure 8 wire into the vehicle for the switch, I found a big grommet behind the brake master cylinder. Finding an appropriate spot for switch is a challenge. The spot on the RHS of the steering column looks like a perfect as it looks like there is a 'dummy' switch cover, but it isn't! There is some complex electrical work attached on the rear RHS of this cover. I experimented with a hole in the LHS of the 'dummy switch cover' for a switch in the early stage of trying to wire the lights in though the fuse box, The switch fitted worked, but when this system failed, the switch and associated wiring was removed and I made a cover to hide the hole I put in the dummy switch cover. It was here that I decided to go with the XBB system. I hope this rambling makes sense to you Darren. Golden Eye
