Keep the caliper guide pins lubricated and the brakes will not have a problem. The correct grease is essential not copper grease or red rubber,  use a proper guide pin PAG grease like Molykote G3407 specifically designed for caliper guide pins.

The DPF mode overfuels to allow the filter to heat up to burn off the soot. If the engine is stopped before the cycle has completed the excess fuel ends up in the sump. Jag forums have examples about it. 

Or buy them from ECP for £50 and be duped into thinking you get a bargain with a "discount" code & pay £25 when other sellers charge less at all times!! 

Comparing a modern Lexus that only needs 12v to power the electronics to a old refrigerated diesel lorry interesting but hardly relevant.  The Lexus Battery is an AGM type so performs well in low temperatures & has low self discharge & can charge at a far higher rate.

The Lexus system can output 40A to charge it when required.

It isn't just a standard lead acid as found in a lorry. Probably why is costs £250.

I agree with your comment regarding older cars

Neither of my cars are old both less than 3 years.    All the figures are if the Battery is fully charged to begin with though.

My other car a pretty new BMW with the latest diesel engine has no such problems with the DPF. If I have done a few short journeys it does an auto regen which makes the exhaust note  a little deeper for around 20 mins other than that not noticeable.  The 2.7 Jag is an older design pre Euro 6.

Diesel technology has moved on since 2003 when Ford announced the 2.7.

You are correct in that a unused car will eventually go flat. More likely in a Lexus hybrid with a small 12 Battery although my GS quiescent current was 15mA so should last several months assuming the Battery is fully charged.   My BMW which has a huge 12v Battery in comparison, 95Ah should be able to supply the 45Ma current for 20 months.  Maths isnt my strong point so may have got a decimal point wrong although a collegue parked his car up while posted overseas and on his return 6 months later it started first click.

45mA = .045A   so 95Ah is 87 days before flat so even allowing for only 50% should be good for 10 months.   The GS  assuming half size Battery then 5 months. I measured the GS & the quiescent current was 15mA so well you do the maths.

A set of Bosch for my (other non Lexus car) is still cheaper at Wiperblades.co.uk even with the 50% discount at ECP.  ECP just double everything then offer a discount code don't be fooled.

The IS has a 48 Ah battery and the current draw is more than 15mA with the alarm and keyless entry enabled.

I measured it and it was 15mA once everything had shut down which took 15 mins iirc.

Blueskysea B1W WiFi Mini Dashcam  This is the one I have. Neat & small. Good picture quality & links by wifi to your phone for set up & review of footage.

The quiescent current is around 15mA so a 55 amp hour Battery should last 3600 hours or 150 days. Dont leave the key fob in or near the car as this will keep the electronics alive.  imho if your Battery was flat after a 3 week holiday then it is either faulty or was not fully charged.

As for the MOT status of reversing lights. They are Not part of the test.

Later this year they will be if if the proposed changes happen.

And because light units cant be easily taken apart ill try to source unit with reverse light for both sides to have proper light at the back. 

At least one fog is required though as that is an MOT check.

Someone' stated they' change the rear reflectors to be high intensity lights. Sorry pal but that'd be a MOT failure and illegal.  Cars Must have rear refectors.

 

I looked into this & can tell you that the LED lights that replace them also have a reflector so would pass an MOT.  I never did it as I figured fogs & reversing lights are not used very much!!   The cost of a LHD lamp for the extra reversing light was also costly.  Thanks Pal!! 

Slide the cluster out I bet some wires have been changed. It must be unit from a LHD to give two fogs but no reverse lights.

It was a mod i was considering on my previous IS but never actually did it. I was going to have two reversing lights & move the fogs to the reflectors in the bumper.

If I recall correctly, Ford developed a heated front screen and patented it so other manufacturers couldn't copy it

They did but thank goodness. I drive Ford hire cars and loathe looking through the wire elements which to me are clearly visible. No thanks rather have a fan & a clear glass windscreen!!

The recently well advertised video from the Police shows the thieves using a relay box next to the car and a high gain antenna to pick up the keyless signal from the fob.

Most high end cars are stolen by plugging a device into the OBD port and cloning  a new key same as a main dealer will do if the fobs had been lost.

If you are worried just put your fob into an RFID pouch.

I don't want to knobble the luxury features of my car on the highly unlikely chance of it being stolen in this way.

When you say type anything into Google may I assume you mean on one's mobile phone not using the Lexus remote touch?

No use the car joy pad & use the Google icon in on the Nav Screen. No touching the phone screen. You do have to install & Blue DUN app though.

How exactly does one request that it looks for shops etc?

It uses the Google search function in the nav screen menu. (needs a data connection to work)  Type anything into Google & if it finds it it transfers the coordinates and navigates you to it. Basic but useful at times.

Having a key/fob constantly transmitting a signal, just so that we don't have to press a button, insert key and turn it - especially when said signal seems to be an open invitation for the car to be stolen easily - just seems pointless technology to me and something that was added to the cars just because it could be done, rather than an actual need for it.

Keyless entry is mighty convenient & one of my favourite features on the GS.  It is very secure if you keep the fob safe.  I tried a biscuit tin & it still worked but inside a metal cafetière it didn't. So if I am worried that is where my fob will be at night.    

Back in the day thieves would just snap the ignition lock & join the wires.  As vehicles have got more sophisticated so have some thieves but more likely professional gangs stealing to order rather than joy riders.

Why are keys 'active' all the time? Surely it should only transmit a signal when a button on the key is pressed?

My GS is keyless entry & start and I don't have to press a button to unlock the door or start it. If I walk near the approach lights switch on to.

Had a good look round a Toyota CH-R Hybrid at the Toyota dealership next door, this might well be wife's next car and another hybrid in the family.

 I test drove a Hybrid Auris & it was dire no power and ran out of steam on a slight incline. The CHR has I believe the same power plant

Just place your keys (don't forget the spare) in a tin box overnight.

Just tried keys in a biscuit tin & the car still opened.

A new set of good quality pads & grease the guide pins with the correct grease like Mokykote G3407. . The guide pins are the key & they often get greased with copperease which isnt a lubricant.

This cured the squeaky brakes on my GS.

Buy an RFID bag on eBay if you are worried. 

Lexus cars are not aimed at tattooed louts who like to thrash the engine & try to wheelspin & drive at 90mph at every opportunity.  That is what he fails to grasp.

  The RC isn't slow but also isn't a Golf R.  If you dont like the bongs then go into the menu & turn them off.  Not an engaging reviewer either regardless of his drivel.  They do it to get views which earn them money the more clicks the more they earn.
