Got a chance to remove and clean the maf sensors yesterday, what a very marked difference in overall performance. Engine light still on but i think that needs cancelled with a code reader (ordered one). Thanks again all.

Took her for a long run yesterday, for most of it (for the first time) used the manual select/shift which allowed me to use more of the rev range and now the engine appears a lot less lumpy.

In auto the normal rev range on Shetland roads is 1000 - 2500, I think because of the extra upper lub added to fuel this helped clog a censor, injector or plug. 

No dual carriage ways or motorways on the island.

Thanks again all.

I think you could be right - or it's just one of those weird coincidences that happen occasionally.

P3190 means low engine power and the other two are self-explanatory. The good news is that, despite the dire warning about the hybrid system, it's quite unlikely to be that.

I haven't got a service manual for the LS600h but the RX450h manual has about 10 pages of stuff relating to P0172 and P0175, the first one of which is below showing possible problem areas, starting with the most likely. The first thing I'd do would be to clean the mass airflow sensor.

It does sound like it may already be sorting itself out so fingers crossed for you mate.

Thank you very much for your help, it means a lot to an LS owner in the middle of the north sea....lol.

Cheers mate.

Friend arrived this evening and started the car, awful smell of petrol while the car warmed up, still with warning symbols on dash. Ran the code scanner and came up with....

The car spluttered and held back as i took her around the block but with no warning symbols on the dash, as she warmed up she started to run cleanly and the charge indicator for the hybrid Battery rose to full charge.

I think my over generous application of upper cylinder lube could be the cause of this problem, unless the error codes indicate anything other. help Herbs.

I don't have the answer but my 2007 Ls600hl displayed the same message and went into limp mode.  I was on a 70 mph dual carriageway and 200 miles away from home and friendly dealer so I just hit the gas pedal harder and it eventually recovered.  Drove the 200 miles back home and took the car to my friendly Lexus dealer who could find nothing wrong with the car, no codes, just nothing.  This was last year and about 6000 miles ago and it had been running fine ever since.

I couldn't be that lucky. This happened to me from cold start first thing in the morning.

Sad to say but yes, it is.

If at all possible you need to get the codes read with Techstream, which is the very same diagnostic software used by the techs in the Lexus dealer workshops. A basic code reader like those mentioned above may not be able to read Lexus-specific codes to do with the hybrid system or, if it can, it may not be able to narrow it down far enough.

For example, code P0AA6 covers SIX problem areas so the sub-codes help to narrow it down. P0AA6-123* will point to one thing; P0AA6-124* will point to something else; P0AA6-125* to something else again and so on.

*Not actual sub-codes, but just for illustration.

If you have a Windows laptop (even an old one running Windows XP) you could buy one of these cables. They almost always come with a pirated copy of Techstream but as we can't be seen to condone software piracy, the correct way would be to freely and legally download it from here https://www.lexus-tech.eu/DiagnosticTools/Setup and pay for a block of time to use it (€5/day, €10/week). Either way, you'll still need that miniVCI cable.

A friend is going to call around tomorrow with his autel code reader and see if he can call up any fault codes. No Lexus dealers in Shetland so fingers crossed, serviced by Lexus and hybrid Battery checked last October prior to me purchasing her in November.

Just had her detailed, beautiful car when she moves.

Thanks for all the replies, further developments this morning...

Drove the car 100 yards this morning but had to limp home home on electric motor.

Restarted the car and took these photos, guess its a bit more than a duff 12 volt Battery.

I have a 2009 SL600hl, over the last couple of weeks the engine light has come on for a few days

and then stayed off for a few days only to come on again and repeat.......

What do owners think is the most likely problem developing?

Could the addition of ( a bit to much ) upper cylinder lubricant in the fuel tank lead to this?

Thanks in advance

Thanks for the replies. If it needs to be adjusted by the dealer we have a very good Toyota dealer in Shetland, i will ask them.

Hi all, just taken on a 2009 LS600hl and, at this point, have two questions

a) Can i change the tyre pressure display for the five wheels from "Bar" to "PSI".

b) Can i remove the "Passenger set for Adult seat belt" on the central display between the temperature settings as it's on all the time..

Great car

As the damage is so near the seam I think total replacement is the the best option. 

If I had seen this on a forecourt I'd have walked on by and bought a Merc or Beemer, but having arrived in Shetland

I've fallen in love with her, the 450h is such a relaxing car to drive.

Wouldn't it be cheaper to get a second hand seat from a breaker here or have you already looked at that option 🤔 

I have been looking for a secondhand seat but no joy, i just wondered if this supplier had been used by any members.

I have been looking for a replacement drivers seat squab since purchasing my 2007 450h unseen earlier this year.

Have any members dealt with a US company called "US auto seat cover"

Thanks guys for your advise and after much online research I've plumed for giving this a shot just on the rear screen.

No rear screen wiper on the 450h, what is the best application to promote water runoff.

Very interested in locating a "Trim Specialist" that members have used.

GS 450h, what a crackin car with one wee niggle the driver seat has a couple of slits in the perforated leather, one in the back support and another in the  base cushion.

This is buggin the hell out of me, as it's perforated leather it will only get worse with time.

Have any members used   https://www.theseatsurgeons.co.uk/ ? They can do a standard leather refit for for just over £1k.

Hi guys, just purchased this GS 450h 2007 and having it shipped from Aberdeen to Shetland.

I notice the rear nearside reversing sensor appears to have lost its colour cap, is it of any importance?

Not received the car yet this is one of the drop off pictures from the transporter.
