Evora Air conditioning failure

[Markindevon]

I ordered an OBD2 reader with re-set capability so will have a go at this tomorrow when it arrives.  The drive belt is about 2 years old so really should be OK and it's only just had its annual service with SWLC who I'm confident would have pointed out any issues with it...

From what I understand from a post about this issue having been sorted on later V6 cars, the sensitivity of the system is a bit high and so this seems to (potentially) be a glitch where there's a detection of a pully speed differential that doesn't really exist (or is very minimal) but that once it's been flagged in the system, it won't re-start the compressor...

We shall see once I've been able to do a re-set!

I tried resetting mine and it made no difference. Came back again. I also couldn’t reliably read the code. It needs an OEM Lotus reader for this particular fault it seems and no combination of other car choices will give you the right error codes. 
 

im not sure if the early cars had the same sensitivity problem as the later ones do?

[Markindevon]

Thanks for that - oh well, I'll give it a try!

If it doesn't work, I guess it will mean another trip down to SWLC to get James and team to take a look! 

I really want it to work by early September as I'm off to the Autumn Irish weekend with my wife and she won't be happy if it's hot and there's no a/c! (though it is Ireland so probably will rain :-))

I doubt if any off the shelf reader would be able to read that area of the car. The generic readers are designed to access the standard engine codes.

I have a specialist reader for TPMS and have seen there is one that can access airbag.

SWLC have the factory supported reader/tools that they helped develop!

Good news… I bought a cheap OBDII reader from Amazon (MOTOPOWER MP69033), it couldn’t read the a/c codes but it could clear them.

A couple of button presses and the a/c is back!

Good going for less than £25!

Be interesting to see if it keeps on working.

I’ll let you know… as long as there’s no mechanical issue with the belt (and I’ve been assured it’s fine) or pulleys, I hope it will be ok, or at worst I’ll just have to reset it again…

doing the Autumn Ireland trip with my wife at the start of September so that will be a multi-day test (I always leave the a/c running)

  How did you pick that reader, just seen it says in the description it does has EVAP test, not seen that mentioned on other 'standard' readers?

It was recommended by a Haynes review that I stumbled upon.
