  1. I think the odd time mine did it, from starting, was when it was cold. I always let the car warm up for a minute or two before driving. So presumebly in my mind the gearbox oil is cold/thick. Do cars in UAE usually run thicker oil to counter the general higher temperatures? If its not a software issue then it can only be harware. There is a clutch control valve, which presumabley is what controls the 'take up', so there may be an issue with that, the oil or maybe the transmission oil needs flushing out if there are some contaminates in there? Im no expert btw, this is just me thinking out loud!

  2. A very odd time when starting from cold when I first engage drive it can 'clunk' a bit, but it is only the odd time. Also because I drove everywhere in sport manual for the first year, the tcu learnt this so now in auto it isn't 100% smooth as I presume its edging towards a sport change rather than a slushy auto change. As you have changed the fluid and reset the tcu im at a bit of a loss. It may be worth searching the issue relating to toyota cars as if its a known gearbox issue then it will also show up there. Im sure I read that the gearbox in toyotas when it has issues, it was known to always one of two solenoids.

  3. Yep I realise that cheers, mine 'seems' to be genuine and came overnite from a car spares company so hopefully it is genuine, I could have got a cheaper one but didn't. Its reading alright on the obd graph but will have to see. 

    I have no issue buying genuine parts when needed but neither have I an issue getting non lotus genuine toyota parts like fuel pump, ac compressor etc over the years at much reduced mark up. Everyone has to make a living so no complaints but the ac compressor on my old Evora na saved me £1500. I dont doubt fake parts are a massive problem.

  4. Yep got mine off ebay!  I didnt fancy doing it with  hot exhaust or a blow torch as the one I did has very little access room (pre cat between engine and fire wall) and was mainly done by touch. After googling I found the logic behind the fault code, voltage outside limits for a set period, after the second time it triggers. Does sound like yours is either water getting in the connector or the cable has rubbed/melted and the water could be shorting it out. I've got the vag-com/vcds software on my pc which also does obd11, its good as for example, I can see the output from the two sensors on a graph so you can compare them easily. The sensor 2's should be straight forward but much easier with a pit or ramp!

  5. For future reference, yes its quite easy and straight forward. You have to remove the heat shield from between the engine and bulkhead, this is straight forward but one nut is captive the other is loose so you have to be careful not to drop it. I did this with the engine cold so needed my long bar to crack the sensor loose. One sharp tug to break the seal and it then just undid by hand. New one in and all fitted back. The fault light has cleared, the OBD reader is now clear apart from the catalyst cycle needs time to reset but need a longer drive, the 02 sensor cycle has reset.

    For reference, I googled the lotus part number which gave a generic Bosch part number and I bought one of those for less than half the price of lotus and I spent £12 on a set of o2 sensor sockets, so all in about £70, a lot less than just the sensor from lotus.

  6. Strattons but they can be a bit hit and miss to deal with. As far as i know, and hope to be proved wrong, but don't think the factory have anything to do with them since selling strattons all the spares. 

    How bad is the crack? Ive only ever parked forward once 😂, i repaired mine with a knife and some clear lacquer. The problem i have is that it is bonded on as well as bolted! 🙄

  7. Ive got a bank 2 sensor 1 error which appears to be the precat on the firewall side. Ive had a look round but not found anything specific about replacing this sensor. Anyone done this got any advice? I cant see it from above and the bulkhead panel sooms to be to the side of it so dont know if this will help. 

    Cheers Gav
