Not sure, I got a complete pack on ebay which included the software. I believe you need to register on the Lexus website to down techstream directly. Can see quite a few people selling the combo pack of cable + disc on ebay for around £20.

Probably cos your statement is illogical. Just because your cars didn't have an issue, doesn't mean there isn't a physical issue with their car not related to fuel. Lots of other things than fuel that could cause this issue.

Assuming you have a laptop, you can connect that to tech-stream and do it yourself. The cable cost me like £20 on ebay. Most standard OBD readers will allow you to get the codes out however, which you can lookup online even if they aren't programmed into the OBD reader.

Never seen my GS450h drop below 30mpg even after much round-town, except literally while running when stationary for a long period and that normally only cos it was using the air-con/heater.

Possible you just ran the 12V down rather than anything wrong with it. Because all the 12V has to do is start the computer and then open the relays to the main hybrid battery, if its basically flat it may actually still manage to start the car. Had this a few times on my last 12V battery when it was, well working but it had basically no capacity left after 15 years so was very easy to run it flat if you left it on without the engine running for any period of time at all.

If it was misfires, you'd 100% have error codes.

I think its 5.2 if you turn the electronics off and how how to pull off manually extremely well. You lose a bit with the electronics on as they are a bit overly paranoid and limit the power more than is needed at lower speeds.

Most have integrated batteries so its not possible to easily replace the battery. Detachable batteries would likely become unreliable if places inside a wheel and spun rapidly 😉

Mercs are great, they are very similar to Lexus. BMW and others, not so much.

Yep, its the great thing about buying older high-end cars. Cheap and high quality. Only thing I miss is all the phone gadgets newer cars have.

Yeah that's a decent price, around what you'd expect if they do decent work (check warranty length) But the amount of difference it will make is negligible. I'd not bother spending anywhere near that much unless you need to replace the exhaust anyway. I mean I can tell it sounds different if I really concentrate on it, but no where near enough difference to be worth anywhere near that much.

True, but its less of an issue if its going into the water since the coolant fluid tends to turn into a horrible sludge when combined with oil and high temperatures. And engines don't like being lubricated by sludge 😉 Might cause some issues with the cats through.

Should see signs of that in the oil if its leaking into the engine.

On my GS which is also pre-facelfit, the parking sensor button is in the drop-down control panel on the far right. If the parking sensors are active, you'll have a light on the dash. GS doesn't have soft close doors no.

For someone as inept as me, procedure was call garage, arrange time, drive in, wait 1 hour, drive home warm 😉 I looked at doing it myself but the garage only wanted £70 to do it so by the time I brought everything and messed about wasn't worth it for the £20 or so I'd save.
