Curious then, does disconnecting the battery on Gems reset some adaptive values?

No, as said, all it resets is the windows, sunroof and radio, adaptive values stored in the GEMS unit are stored end of. Holding the throttle open won't do anything either as the problem is a high idle not low. The TPS value stored for closed throttle has remained but by mucking around with an incompatible TPS he's caused the value at closed throttle to be set lower than the TPS is capable of supplying. So GEMS thinks the throttle is partially open all the time and is opening the IAV to act as a progression jet. I caused the same problem by starting the car with the TPS disconnected so it saved the low value (i.e. zero) as closed throttle so as soon as I plugged it back in the 0.7V was seen as throttle open. Seems it will self adapt downwards but not upwards.

I doubt it as that is just an RS232 to OBD cable with no active components at all. I suppose it's always possible that the interface in the cable is just a USB to serial adapter built in but I doubt it or you could use a straight cable and separate adapter. It's probably very similar to the Chinese copy Opcom unit I've got to talk to Vauxhall/Opel cars and the similar one I've got for Vagcom (VW/Audi) and they aren't interchangeable.

The cable shown on his website does appear to be a USB to OBD cable with the built in interface and it does say that it is a specifically designed hardware and software product so I suspect it won't work without the cable.

Comes with the required cable but that will be sent by post so might arrive before Christmas.....

WTF didn't Mr Tune Right plug in and reset there and then?

Because like everyone else, he can read and reset fault codes but almost certainly can't reset the adaptive values. But you would have expected him to have plugged in his machine and proved he can't do it*. As OB says disconnecting with battery and leaving it for a minute, a day or even a millennium won't reset anything other than the windows, sunroof and radio. Get the drill out and elongate the mounting holes in the TPS so you can turn it. It WILL work guaranteed.

• In saying that, I got an email from Mymystery yesterday. She's just outside Paris so in what you would consider to be a reasonably civilised area but it's only taken 3 months of cancelled appointments and excuses as to why they can't do it that day to get her wheels balanced FFS.......

I've found that a microswitch that is on it's way out will fail more often in hot weather. Probably something to do with thermal expansion. Until I changed the microswitches in my drivers latch I used to get dancing locks but only when it was very hot.

Doesn't explain problems in Yorkshire though.....

Maintained and in great mechanical condition is normal for piece of mind, leak free is like wishing for a white Christmas, it may happen once in a while but it'll never last and you certainly can't rely on it.

It's linear from idle (about 0.5-0.7V) up to wide open throttle at just short of 5.0V. I've done it and it works, believe me.

Didn't have any (other than the one at the Latvian border taken last year that has already been posted) so just nipped out and got a couple.

Olive trees and the house where we are staying that can just be seen lurking behind

and just along the track with Nice in the background. Nice airport is the bit on the far right sticking out into the sea.

It may be slightly overcast today but it's still bloody hot.....

I always thought the dangly wicks were to prevent a build up of static to stop travel sickness. Doubt they worked for either purpose......

They share an ignition switched supply. Fuse 17 powers the brake lights, the HEVAC display and EAS display. Although the diagrams don't show it as having anything to do with the radio, I found that with an intermittent connection my radio would go off as well as everything else on that supply. It comes off the only connector on the back of the BeCM (accessed from the rear footwell) and is on a white wire at one corner of the connector. You'll see which one it is, it's the one that is starting to look burnt. If the HEVAC display dims slightly when you put your foot on the brake pedal, that connection is getting warm.

Clean it off and see if you can see where it is leaking from. It's not unknown for a weep to come out of a weak point in the weld on the axle casing itself.

Course it will, you only need to insulate the bits of wire from ground and each other. If you were really brave you could leave them as a three dimensional birdsnest but I wouldn't advise it.

Make one you lazy bastard, it's only a plate with three holes drilled in it.....

Yup, you got it.

You've got it right. If they can't do the reset, your easiest option is, as I suggested earlier, to enlarge the mounting holes so you can turn the TPS slightly. That way you can get the voltage back into the correct operating window.

Skipping in reverse? I would have expected the wear to have been on the side of the chain that is under stress when going forwards.

Key in 'ole, turn to lock and hold there, press lock on the fob and hold until the LED starts to flash faster, release button on fob, tunr key back to centre. Then do the same with unlock.

No, or it may plug in but there won't be a connection if you have the two ends with the central socket rather than the pin. It's the same as the reversed polarity SMA connectors used on Wi-Fi adapters so you can't plug a high gain aerial onto them. The plugs look the same but if you look in the centre of the connector you'll see either a socket or a pin. So SMB and MCX would appear to the same except the polarity is reversed on one of them.

It's not important just mildly annoying. With it parked 15 feet or so from a wall, the beam cut off from the RH light is about an inch lower that that of the LH light. Easily within spec for the MoT just not perfectly symmetrical. Maybe I should just reverse into the parking space so I don't notice it.....
