Bought a set off refubed wheels a few months back and yesterday i got the tyres swapped over. Cleaned polished and sealed them with wax to make it easier to clean them, gave the tyres a coat of rubber trim and also put new caliper decals on! They have a light chrome finish to them which im getting used to, if i dont then the old set's gonna get redone in anthracite and put back on! C&C's welcome.

Write/contact the previous owner-usually the best solution.

Thanks everyone - opened the fob up and battery a C1616 - £3.99 at Halfords the car is worth the expence!! Working fine now.

Very clean looks shiny like mine lol Sent from my iPhone using Lexus OC

Exactly, they must surely have a flow chart for this kind of thing and that should have involved checking basic stuff like fuel pressure. I'll be persuing it quite aggressively. They actually told me they would get to the bottom of it. Doesn't inspire much confidence does it? I have posted up the results and photo on the USA and Canda forum.

Thanks Baz, I checked for error codes the day after I got it back but there were none. So it's not producing any but will regularly check this. When you hit the 4000 rpm limit, there are no warnings or flashes. ...However, if (whilst driving) you slip it into N you can rev past 4000. If you then put it into D the limit seems to be there and it slows down until it reaches the speed it would be at that RPM, then just sits there. Will give this another go though. When I checked the Transmission fluid yesterday (all warmed up after a drive, cycled through the gears and left it in P with the engine running, etc.) the level was right up to the top of the HOT mark, in fact, over that part of the dipstick and slightly onto the cable. So it's not low on fluid. Will try the rev-up and floor the throttle routine tonight, to see if it still drops to 4000 RPM. Hi Mudguts Waited to hear how your diagnosis went after my last post on this subject,I suggested then there may be a problem with the information transmitted between the engine and gearbox within the ECU ,Having read your post this morning I now feel your problem still lies in the Gearbox and could be related to back pressure readings from the transmission fluid sensors .It sounds like the ECU is receiving info from the gearbox that is instructing the engine to go to safe mode,This is the mode that prevents damage occuring in the gearbox after a working part as failed, it normally puts the car in second gear and does not allow it to change up so a limited progress can still be made,although this is not the exact scenario the fact you can rev beyond 4000 revs when in neutral leads the cause to the gearbox and the information it is transmitting. I had a similar problem when I first bought my car and the second gear solenoid failed and it would not rev up beyond 4000 revs and would not change up. It might be a faulty solenoid as they work with the back pressure within the gearbox to gain the optimum moment to facilitate a smooth gearchange. Have you tried the diagnostic codes for the Gearbox as you will get these showing any faults on the electrical curcuit within the gearbox. These are read through the ect light on the dash.

Hi with regard to the changing of Engine ECU It is not hard to change, it is under the passenger side front console and is accessed footwell upwards behind the lowest panel of the console, the panel is removed by screws located in that immediate area. On the ECU which is a flat box approx 15cm X 10cm X3cm there are four plugs to the back and one to each side ,these are relays. the ecu plugs only go in there respective sockets so can't be mixed up when reconnecting, they have pressure release clips on the plugs so they don't just pull out, after you have unplugged one of them you will have learned the process for the rest.Make sure you dissconect the battery before removing the ECU and dont start work for at least 5 minutes after dissconecting the battery.

None of this will fix your rev problem MAF meter all the way. Faulty when under load of the throttle. This problem will not show up in any garage which include lexus dealer unless they go out on the road with a laptop inside the car while driving full stop. Just a quick second thought what work if any was carried out before the fault or did it just happen overnight while driving? Also don't scrap, I'll have it with the problem if car is in ok condition. Baz.
