Just one thought (I know you mentioned Tiger seal) did you change any rear light bulbs before the leak started? I once developed a boot leak on my 2004 model RX300 after replacing a rear light bulb. I hadn't got one of the the seals seated correctly on a rear light cluster. The seal was a circular grommet type one in the bodywork where part of the plastic light cluster actually went through the body work. Re-seated it and hey presto leak solved. I found Capt Trolleys has worked for me, but you are right about having to be careful with it. It really can make a mess if you have over spill and don't clean it off. I found trying to clean it after its dried not really an option with the caravan may be different on car paint but I wouldn't want to risk it.

If you can find the source of your leak this may help fix it. I had a windscreen seal leak on an RX300 I owned this cured it and I have successfully used it n other situations. It works as described.. http://www.captaintolley.com/product-info/ Available via eBay

Brill Thanks for that I have sent for a heated one from 'Car Door Mirrors'. I have to say I have never noticed the door mirrors dim anyway and even if I had I don't see how Lexus can possibly justify £275+VAT. You can buy the complete mirror new for £500 +VAT that means more than 50% of that is the mirror glass. If you want my opinion I'm afraid this looks to me like a case of Lexus fleecing its loyal customers, especially now you have to have un damaged door mirrors to get through the MOT.

I have just phoned Lexus parts dept at my local dealership to price the Mirror glass to fit my offside door mirror in my 2006 (56 plate) RX350 SE-L. Mine is cracked. Apparently because it has something special about it they want OVER! £300. Does anyone please have any suggestions of where to get a realistic priced replacement Mirror Glass... Many Thanks Paul....

My RX350 is 2006 and hapilly turns out 33.8 - 34.1 on the motorway. I had an RX300 that would do 28/29 on a run and 30 on good days. 😃

I have posted this on another thread but here it is again in case it helps for locking a 2002 RX300 (UK early version) without intruder alarm closeall the doors then insert the key in the drivers door turning the key it in the "unlock" direction (even though the car is already unlocked) remove the key and within 10 seconds press the lock button on the key once to lock the doors or twice to deadlock the doors. This leaves the alarm/immobiliser activated but interior sensors off. This seems to have cured my problem or more accurately isolated where the problem is IE. in the interior sensors system. The PITA is that you have to use this system every time you alarm the car. Does anyone know if (on my early 2002 RX300) is there a way to perminatly disable the interior sensors? is it an ultra sonic or proximity sensor system? where the sensors are located? How do i permanently cure the issue? I have read many of the threads but the problem is its often unclear whether these "cures" are like the one above and needs performing every time I lock the car or not?

I have the same problem mine is an early 2002 version RX300.

Have to say I would never touch Lexus Scotland again not even with a barge-pole and full decontamination suit after my experience. Only after getting Lexus UK involved the best they would do is refund cost of parts, which works out at LESS THAN 50% of the bill highly un-impressed - Avoid like the plague.... The car has now cost me £700 for the AC unit fitted at a non Lexus but good quality garage the problem now is I have the b***dy battery apparently discharging and the Alarm randomly triggering.....

Needless to say still no solve on the cruise control

The lock system I am using at the moment is to lock the doors with the central button inside the vehicle while I am outside holding the drivers door open. Then you hold the handle on the outside of the door in the open position and shut the door itself. Car locked no alarm sounds - God know what my problem is I suspect a battery drain for some reason but the battery is less that 12 months old and the problem never surfaced with my old battery.

Hi Everyone thanks for the reply's, unfortunately this has had to move onto the back burner for me just now as another problem has arisen. ​ Long story Short:. On the way up to Scotland before Christmas the RX developed what sounded like a bearing noise. I suspected the water pump. Took it into a Lexus dealer on a Saturday morning one of their guys had a listen and agreed it could be a water pump but would need to see under the casing to be sure. They had the car Monday fitted a water pump and on the journey home the noise re-appeared. It took my local dealer in Sheffield under 2 mins to diagnose the actual problem as an air-con pump. So now I'm £480 out for a water pump fitted that wasn't needed and will be another £500+ out for the air-con sorting. Currently not a happy bunny :megaangry: Before making the journey up to Scotland An auto electrician had a look at the RX cruise control issue. His analysis was possibly a solenoid in the ABS pump but it could also be the Cruise ECU he is leaning to wards the ABS solenoid because of the "C0278 Relay Solenoid Valve Open/Close Circuit" he is getting from the on board diagnostics. That said because he wasn't able to look at the vehicle while the problem was actually apparent understandably he couldn't say what it was for certain - Aint intermittent faults wonderful? Feel free to chip in with suggestions still if wish. If/When I get it sorted I will post on here to try and help others in the same predecament....

Hi all I have a 2002 (old shape) RX300 bought it with 75K on the clock and now has 103K. It has an intermittent problem with the cruise control thats driving me nuts. If I set the cruise control to ON the green cruise light shows on the dash and it will work for approximately 40 miles sometime around then the cruise light will flicker off/on and disengage the set speed, the cruise light will remain on. The further you drive the car and more you reset the cruise control the worse the problem gets. The Cruise light shows 4 different symptoms starting at one and progressing through 1 - flickers off for a fraction of a second disengaging the set speed 2 - flickers off for a fraction of a second refusing to set a speed T 3 - flickers on and off in a series of patterns (as it gets worse) 4 - it goes off completely. The only way to get the light back on is to press the on/off button Twice or turn the ignition off then restart the car and press the on/off button once (eventually) I generally drive between 50-60 mph but the fault does not seem to be speed related. I have actually had the car stood on the drive engine running cruise control ON (having returned from a trip up the motorway). Pressing the cruise control stick down as if to set the speed resulted in the Cruise light flickering off for a second exactly as would when driving but refusing to set a speed. When the fault is showing turning the ignition off and restating the car doesn't clear the fault. Leaving the cruise off or not trying to set a speed for some length of time while driving does seem to bring it back to some form of intermittent operation but not for long.L leave the vehicle until the next day and its good for another 40 miles or so on cruise. I had an Independent repairer check the On board diagnostics and they came back with three fault codes B1421 passenger side Sunlight penetration photo Circuit defective C1223 Control Unit Faulty Operation C0278 Relay Solenoid Valve Open/Close Circuit Has anyone had anything similar and what was the fix please? Any Ideas Anyone? PLease
