Ah yes, thanks. there sure are plenty of C1241 options. I like the following potential solutions best and will try them first: – Choose a better quality fuel – Check that the tank cap is securely closed – Check the oil level and add more if it is lower than MAX

ABS/VSC/TRC showing C1241 Air Conditioner showing B1421, B 1424 showing as current, and B1475, B1476 showing as historic. That's the Aux battery on its conditioner. It looks like it is pointing at the airconditioning... (NB: thanks for the help getting techstream working AT LAST!)

All good points and that techstream link looks ideal as I'd failed to get it talking to the car (64 Bit windows 10) in the past. will give that a go. THANKS!

I did a post about a mystery whirring noise a few weeks ago, but soon noticed - wait for it - the VSC Warning and Check Hybrid System warning come on about one minute after I put the heating on. Some coincidence. The OBD reader I have does NOT show any errors, but I need to use it to erase the invisible errors, or the car will not start. I'm going to get to Japex as soon as I can, but this is likely to be a week away. QUESTION: Would it be a bad idea to make a 400 mile round trip where the heating will be required and consequently kick off the above-mentioned warnings, with me relying on the OBD to erase those invisible error codes to restart the poor old RX400H? I would rather NOT of course, but it looks like I might have to... I thank you.

NOTE: I tested it today on the way back from Essex (again) no heating there and back until the last mile. Turn the heater on and THERE YOU GO! VSC Warning and Check Hybrid System warning. Who would have though a dodgy fan blower motor could take a car out of action?1 NB: Note that the OBD reader I have got did NOT show any errors, but erasing still worked and the car started just fine. Fan blower motor. Good lord.

All restarted with a handy booster battery. It's a Bosch battery under the bonnet that went in just about 3 years ago. Does the team think its sudden drain does support a failing part elsewhere? I didn't think a failing fan blower motor would put excess load on the battery. Maybe I'm wrong about that? THANKS AGAIN.

I am hoping so, on the basis this looks less costly / critical than the brake actuator pump. A further complication: I was just driving normally and got the cheeky old VSC Warning, followed by the Check Hybrid System warning. When going back to start the car, it's not starting. There seems to be power, it's just not starting. Feels like too much of a coincidence for this to happen / that it's associated with / a result of the cheeky noise...

Ah hello again. I'm back with my 2007 RX400H, the one that had the inverter replaced by Lexus. ANYWAY, all has been well since then, until I got off the M1 on Sunday and a loud whirring noise was coming from the engine. It was not affected by speeding up or slowing down. Not affected by steering. Still ocurred when stationary It was so loud when stopped in traffic, I heard someone on the pavement say 'what's that car making that noise for?' Ahem, yes, exactly. Typical St Albans. I've looked at a fair few other engine noise / belt noise / baring noise threads on here. Oil level looks on the low side, just above the lower indent on the dipstick. https://photos.app.goo.gl/YyL88k1rNdfCzwSG9 If that link doesn't work I'll upload the video. Note that it stopped on Sunday by the time I got home, this video is of it just starting to think about reocurring today. Any advice welcome. THANKS.

Hello hello, I know this thread is from back in the day, but was it this kind of noise? Thanks! PXL_20230228_133914946_TS.mp4 -
Hello from the RX400H Forum. Am I the first person to spot this six wheeler on Google Maps in Saratoga? If so, do I get a prize?

MUCH TO MY SURPRISE, Lovely Lexus / Edgeware Rd called me up a few weeks ago to tell me the part had arrived from Japan earlier than expected and they'd done it. The inverter part price was put down as £4,571. I had the failed Oxygen Sensor replaced too and there's a notable difference in fuel use and hybrid battery use now, resulting in back to 30MPG for the 700 miles I've done since she returned (a local non-Lexus / non-hybrid garage had advised me not to bother replacing it). It's still amazing to me that Lexus replaced the inverter at £0 to me, thanks to the recall. SUMMARY: I owe Ross / JAPEX (in Hemel) a big favour, as without him pointing out that it was indeed slightly BATTY of Lexus Hatfield to state emphatically it would only replace the recall part if the car was showing no fault codes and advising me to call Lexus / JEMCA / Edgeware Rd, who immidiately booked it in. Remember my RX400H was then also sat in Ross's garage for over a week awaiting the AA to pick it up (again) for my appointment. I was convinced I was never going to see it again! Thanks for your advice here, I nearly gave up post-the Lexus Hatfield call. Glad I didn't. I'll pop in to JEMCA with a few bottles of something whenever I get a minute and certainly be back there for services and shiz. THANKS! Haha - one more thing - it was rattling a lot from underneath the other day - I had a look and this part came off in my hand: Mysterious Part / Google Photos - Is it important? THANKS AGAIN.

Well here's an update for you. I spoke to JAPEX who were lovely and helpful, booked it in and off it went there, last week, courtesy of the AA. Here's where it gets interesting. Ross at JAPEX called me and - you guessed it - he'd diagnosed the inverter failing. However, he said, it's subject to a recall. I told him how I knew this and had spoken to Lexus Hatfield and they said they would only replace the inverter if there were no fault codes. Ross found this bizarre, bordering on the ridiculous and advised I call JEMCA on the Edgeware Road, as they're more reasonable. Lexus Hattfield are - apparently - well known for being *awkward*. The AA took it to JEMCA yesterday (£90 charge this time) and Ash from JEMCA called me just now to say: Yes it's the inverter. Yes Lexus will replace it at zero cost. However, Lexus doesn't have any in stock and will have to make one specially. Estimated time of arrival December 6th! Consequently my RX400H is going to be sat at JEMCA for at least two months (assuming our supply chain issues are going to carry on, it coud be longer of course) It's back to St Albans Van Hire's Vauxhall Corsa, in fact I'll probably pick up a cheap one in the interim. I find it amazing Lexus is prepared to fix a 14 year old car with 135K on it at zero cost. Impressed. Lexus has definitely gone up in my estimation even higher than it was already. Lexus Hatfield not so much. Thanks.
