Lent did you fit the protectors yrself or at a tyre shop are they any good

well done Vlad glad you got it working i will know what to do now if mine pops up with error mind i didnt even know these things were fitted

A Hearty welcome to the forum Richard

Well stupid me Steven i checked in the boot and the cover over the battery it as 5 pres stud type clips only one was engaged so it must have been the cover rattling at the resonance caused by the wheel balance thanks all for your replies Robert

I have a mk4 gs450h i have not done much mileage due to the covid situation I dont drive too fast maybe 70 + on motoway but have not had occasion to use motorway. However in september of last i took my car in for service at Sheffield got the loaner car and awaited call that car was done Gary at Sheffield rang said Robert you need new rear discaand pads shall i fit them So i said yes Picked car up drove home no problem was busy so never reached 70 5 days later i got a letter saying i need to take my car in for Fuel pump recall i arranged another visit and took car in for pump change On driving home i did go 70+ and there was a vilolent shaking from rear of car i slowed and it went I did ring Gary who said we havent touched wheels but if you bring it back we will check as i didnt have the time i said i will ring later but due to lockdown I couldnt On urban roads was no problem so forgot about it last night had to go to hull 70 + there it was again as anyone any idea what it could be i did think maybe wheel weight fell off putting wheel balance out but i thought that came in around 50mph TIA

I think we buy Lexus for its realiabilty then worry when we buy it that it may break down I have had a 55 gs300 a 2010 gs450 and now a 64 gs 450 and had no real bother with any of them apart from consumable items so i woudnt bother too much

This is link hope it helps

mine went a few years ago and the part was just over £20 it consists of a long plastic rod the arm and a seal it is a modified part and lexus sheffield fitted in less than half hour I will see if i can dig out the pn num

Nice result Joe nice to know about the source for the tyre sensors i would think at lexus the bill would be knocking on door of 500 notes for all 4 well done mate

Thanks all for your replies much appreciated when i back out of my drive mine too feel like the grabbing you describe but it used to do it on the mk3 so thought it must be somethin g to do with the geometry On that car i had Goodyear eagles and they were whisper quiet i may go that route Thanks again Yes Mark mine do exactly same makes horrible noise on full lock

First and foremost i would like to wish all our LOC members a very happy and prosperous New Year I am running Dunlops on my mk4 450h and they are about half worn but are now starting to sound a bit noisy maybe its the cold weather but was thinking would it be possible to change size to 245 45 18 instead of the 235 45 18 that i have on as it is a slightly higher tyre wall i could get a good deal on this larger size i just wondered if any member had tried it and would it invalidate the insurance Cheers all Robert

thanks all robert

thanks for that peter

was driving down very dark road other day i dont normaly go out much at night i noticed that the indicator stalk and wiper stalk were not illuminated is this the case as i am sure that it used to be i did change my battery a couple of months ago I amsure my 450h mk3 was illuminated does any one know if this is the case TIA Robert

I have been out of circulation for a while due to PC going bang i had to get a repair done but shop had to close Regarding the fuel pump recall they had to take out rear seats to get to Low Pressure Fuel pump and replace it they also put in 30 pounds worth of fuel I have not noticed any difference in the running of car Service manager said some of the GS s and RX s had a bad batch of Fuel pumps that were bad and would have resulted in a shutdown of the pump leading to a bad situation if on the motorway at 70 plus but in truth my car is no different after the refit Robert

Also Ref the Gateway ECU the yanks have been changing batteries thinking they were gone and it as been The gateway ECU initiating Battery drain apparentley there was some bad ECU so TSB said to change same with updated one 89100 30181 and this supposedly cured it as far as i can see in the comments the drain According to them should be 10 to 20 milliamps if it is over 50 milli amps it is suspect I thought it may not apply to UK cars but Russell the parts man at Sheffield said during the lockdown we have had big run on batteries S0.................... i will try and find post for it on US site but google that part num it may come up Robert

Hi Shahpor Yes i got a email from Lexus UK telling me that my car as got a safety recall and to contact my Lexus Dealer when i contacted them they said yes its for the low pressure fuel pump and we have them in bring it in on Nov 2 make sure you have only quarter tank as we have to take rear seats out to get to it. They have been changing them in the US for months and also filling car up with fuel too that was on the TSB wether they do that here i dont Know Apparently the fuel pump shuts off and engine stalls for a few seconds then restarts i dont think it might not be too bad for Hybrids but normal engines i bet it would be quite Hairy Thats all i know about it though Sheffield said they have done a few HTH Robert

John I tried that at Sheffield Russell the parts manager said that battery only as a 12 month warranty and so did the service manager i Thought like you it was a 3 year warranty However the battery that i got from LPD as a 3 year warranty so rarther than chase round woods as i got car from Sidcup i just got a new one i fraered being stranded as it was certain it would let me down. Robert

I too bought Mine from Sidcup went all way from Yorks to there I aggree with Shahpor on all points but the did fit 4 brand new Dunlops on mine

I too got my Battery From LexusPartsDirect was 202 +5 for delivery got it in two days and all is well However i Decided to try the Repair Mode on the old Battery Which was only 18 month old I kept it on for 24hr in the repair mode and is still at 12.7 after 3 days Not on the car I did a bit more research and found that our US cousins are having same problem and they have a TSB for this concerning the Gateway ECU and have replaced that with a updated ECU its behind glove box ( i have not checked Mine) but my car is into Sheffield on 2 Nov for the Fuel Pump recall so i shall ask them about this ECU Num is 89100 30181 now i dont know if this is affecting UK models but there are loads for sale on the Site that most of us use I hope I havent bought a Battery that i Dont need the drain should be 10 to 20 milliamps if its over 50 milamps there were changing them under warranty so i dont know if this affects us the years in question are 2012 to 2014 Robert

Thanks for that Colin it did exactly as you said I took of the fuse brkt and tied it to one of holding lugs and same with earth and put a rubber glove on cables just to be sure went straight in and even the headlights seem brighter the old battery never went above 12.2 v even though i had charged it up with smart charger the new battery was 12.7 when i put it on not checked since Robert

Disable button for inside car is on the overhead console if i have dog in car i disable interior alarm As someone remarked it will be more than likely a fly or spider

Does anyone know if the fuseblock as to be removed first and does the radio need to be swiched of at the on/off switch Thanks

Thanks for that John i found that the battery for my car was 200 from lexus parts direct better than the 250 from sheffield also with 3 yr warrantty sheffield said only 12 month I have charged it a few times with the smart charger when the charger switches off it shows 14 v the next day its 12.4 and following day 12.2 but yet the smart charger graphic says 100% charged which clearly it isnt I checked for earth leakage and there was none but i found that strange as there should be a few miil amps drain So i will have to get a new battery I had a good look at the battery holding bracket and there is some fuses on top held with 2 nuts does that have to be took off before holding bracket as it looks like not much room to pull battery out. Also i looked at the plug for the temp sensor to see if i could disconnect that then realised that there was not a sensor wire coming from the battery not fitted but date on battery is 11/11/18 i bought car in feb 2019 could this have contributed to the demise of my battery When i asked Sheffield if there was an alternative he went to great pains to tell me no as it as to have Sensor and vent plug other batterys dont have them i know i could stick sensor on side but as i said i havent got one one my battery but the plug on end of loom is cliped to side of battery cage Hope some one can help this old pensioner with the removal of same Thanks all Robert
