This is getting seriously annoying now,orange coil appeared again and engine management kicks in no power at all. Had to take it off for the ride home. Have to refit again for like the 4th time since I got it

we've had this happen before, due to damage to the wiring loom.

Check to make sure the loom hasn't been caught or melted, and if not drop the system back down to us and well run it on our Skoda 2.0 184ps for a couple of days to see if we can emulate the issue.

Had a look at the cables/loom yesterday and all appears well. It seems to happen when I get back in the car and it has been skelped by the sun. I will re-fit it later today and if it happens again I can post it back for you to look at it. Cheers

so it only happens when the cars been left in the sun?? maybe worth moving the module or just turning it down one setting.. Not sure what youre set to now??

It is set to 4+1, is that the optimum setting? So what setting would you suggest?

Thanks

I've had no bother at all with 4+1, maybe the addition of Millers ecomax to the fuel makes all the difference, or maybe 2 GTDs aren't as close together as we'd assume? Perhaps we need a preferred summer and winter setting?

After trying a fair few settings, I found 4+1 to be the best for me.

if the issue only occurs when the car has been sitting under the son for a while then it sounds like a heat issue.

VWVirgin: Might be worth trying another program, maybe 4+0? If it truly is the sun beaming down on your bonnet and affecting the hardware then it will probably do it on any program, or if it's a hardware fault it will probably do it on any program. I'd imagine heat from an operational engine making it's way to the box or loom to surpass the heat beaming down on the bonnet though. Are your issues immediate after leaving the car standing in the sun and then setting off, or do they develop over a journey.

Are you getting any more regens due to this issue? I suppose it's important to determine if the limp mode is coming about due to overfuelling (you'd still be needing a regen on your next journey if this was happening), or a hardware fault causing an interruption in reinterpreted common rail or boost signal (such as a heat damaged loom or loose connection somewhere).

I may well try another program but im going to give it one last chance before I do that. Weather is poor at the moment, so going to see if the situation arises in the lashing rain. It does seem to be when the car is in direct sunlight for a few hours, hope in car (which is black) absorbs a shed load of heat so maybe it has something to do with it...who knows. I re-checked all the looms/cables whatever you want to refer to them as and they are 100%.

Yeh, its immediate alright. Literally turn on the ignition and it appears. I have tried locking the car, got back in then somehow it disappears, it seems infrequent. Had my first regen yesterday it what seemed like months!!!!!
