The easiest way to check it's work properly is to check live data of the sensor on a scan tool at ignition on, idle and revved. That should give clear direction of where to go next. If you can't do that then as you said check the vacuum pipes would be best bet. And recheck all egr work done. When egr was cleaned was anything else done? Like manifold clean where egr sits?

did you test the sensor before replacing? Heater circuit is a simple continuity check. Bank 1 Sensor 2 should not effect running. Do you have a pic of your manifold

Have you touched any hoses to dpf or connectors for pressure differential sensor.

If prices were similar I would go with lexus warranty personally but the others aren't too bad. Depends on each case but I would expect inverter and gearbox to be part of any warranty as they dont really suffer wear and tear

No experience with their condensers but i have used their radiators. They are on par with denso for quality but easier to get, which means warranty is easier to handle if the worst case scenario happens

@PatrickD9How many miles did you do for 1 litre of oil to drop? What oil was used at last service? The garage can check connections at ECU and scope the sensor to see if they are behaving correctly, if they are then it will be timing related.

What are the registrations? I might be able to help

Did they tell you the fault? as in condenser is leaking or joint to condensor is leaking? You might be able to get away with just the seals if it is just the joint, which is pretty common. Valeo would probably be easier to get a hold of if you want to pickup from a local parts shop.

Its a large air filled tube with pressure sensors across the front bumper. Any disturbance will set it off.

You wouldn't fail an MOT on LED sidelights unless they were blue so do be too concerned about it, just by good quality LEDs and enjoy.

Warranty comes down to the garage that inspects it and the conclusion they have come to. In my experience it is very little to do with the warranty company as the inspector will just come and see the car and take some pictures. A HV battery can be a wear and tear item, but if it is a result of another fault like fuel pump for example, then more often than not they would warranty the lot. It's hit and miss but if you have a good garage that are on your side, its more often warrantied.

Firstly health checks are done online via Techdoc not techstream, which is the diagnostics tool. Toyota techs have toyota accounts therefore a lexus VIN number would not be recognised on that system and would not allow service/repair information and hybrid health checks. Some manager or directors may have access to both in which case it can be done at that garage. Toyota service sheets are also different. It's important to to find out what service check sheet they are following before committing to a garage as you might miss important service items. Agreed the cars are the same as most parts are from the Toyota parts bin, which is pretty much the same as any other manufacturer group. Different account permissions, same website.

Aslong as the LED fits in the housing and are of the same type they will work fine (e.g. 501). If you fit LED bulbs double check once fitted that they do not shine (very dim) when lights should be off as you will get back to your car with a flt battery

Toyota techs wouldn't have access to lexusonline accounts which is how the HHC is done, which is another reason they can't do it

It does work but it would be more useful in a country that sells poor quality fuel

No it's not that complex, but mechanics still get it wrong. The first two will lead to braking issues and actuator noises, which is why I would like to know what the independents do. Without techstream you need to go into ECB invalid mode, which not many people know how to do.

Try toyotas own fuel additive if you actually have an issue that needs cleaning

Stones getting caught in undertrays is common. rear brakes can rattle too.

Good discussion here. I think a lot of what you pay for is for someone that knows what they are doing to do the job right, using genuine parts too. Always find it funny the 10k schedule gets brought up as a negative. Toyota/Lexus hybrid engines are extremely reliable and I think a lot of that is down to doing the basics right. Oil changes should never be 18k+ or 2 years etc. like BMW or any other manufacturer. Oil will degrade way before that and they bump up the fleet high mileage cars to 12k because the car would typically spends more time at operating temperature and cause less strain on engine and dilution/deterioration of oil. I've seen some interesting services done by other garages, which make you wonder if they were trained at all.

Ar filter is 40k service, pollen filters come standard (white) or upgraded ones (grey) which have activated carbon to reduce odours etc. entering cabin. The carbon type may be standard for lexus, I don;t know. Diff oil is essential every full service as its on the service check sheet. That would probably void warranty if not done

Anyone can do an oil change, I would love to know how they do the brake fluid change and check the gearbox oil

Ask your dealer to update the media system and see if it helps

Get a quote from accident repair specialist, your insurance may even give you a contact number if you ask them who they use

To compare like for like you need.. 5L 0W20 SM/SN Engine oil (Uses 4.5l) Oil Filter, Sump washer 2L LT 75W85 Diff oil (Uses 1.4l) 2x Diff seals 2032 remote key battery 1L Brake fluid Dot4 Screenwash satchet Pollen filter (the fancy type) Hybrid Health Check Cheapest way to get dealer parts is via a trade discount, so if you know anyone..
