RRS is derived from the ABS ECU if I recall correctly, not the suspension.
Yes, I'm sure you're right. My mixed up mind had overlooked the fact that I was looking in the Motronic inputs and not the EAS!

a couple of other things!
I noticed that the Rough Road Signal is flipping from 0V to 12V for about half a second every two seconds ish. NO idea what that's all about! but I suspect it has a lot to do with the suspension deciding to hit offroad mode on the motorway @70mph every now and then. The dancing suspension is a bit further down the list right now but if the RRS inhibits the knock protection while I'm having mixture issues I'm a bit more concerned.

I've noticed what looks like a water leak/drip a few times when my wife pulls away from parking. Coolant levels seem OK so I've kinda ignored it. To get at the O2 sensor I parked with two wheels on an 18" high verge and saw that the leak is a pretty steady drip on to/past the passenger side catalyst (that was the high side). Is there is a windscreen washer line or something above that area? It's been dry today.

Well it's not bad, but it's not perfect....
The general symptoms are:
Low MPG (2.8/-2.9 miles/litre on LPG)
Hesitation on Petrol at about 3500 rpm on hardish acceleration (seems OK on WOT). No hesitation on Gas (maybe because the LPG is richer?)

I'd had a code showing a sensor fault for the upstream o2 bank1, which I tried to change but I couldn't undo the bloody plug*. So, just in case it was throwing the code because the LPG was running too rich for the ECU to lean it back out I reset the adaptive values and took it for a drive on Petrol only to see what happenned.

Immediately after reseting the adaptive values, the idle went to hell. Nasty and lumpy. It took about 5 minutes to get back to normal. Then I took it for a short drive. It was weak, very weak but it kept running and slowly improved.
Codes: Adaptive values out of range, both banks. Knock sensor (1 time). Strangely, I didn't see any misfires recorded on the misfire screen.

I cleared the codes and did ~35 miles on petrol on back roads and tried to get into every part of the rev range in low, medium and high throttle openings. It started out pretty grim but did settle down to being properly driveable, with the exception of the 2/3 throttle hesitation at 3500-4000 revs. You have two choices at that point, back off and let the 'box change up so you can pull away again at just below kickdown or just floor it and it moves on again.

Finally I parked her up and checked the codes again. This time just the "adaptive values out of range, signal too high" for both banks.
So.. I don't think the 02 sensor is necessarily bad. I've been watching the live output and they both seem to switch between the same ranges (about 0.01 to 1.4). Bank one did take a while to read anything from cold(ish) after the first reset - I don't know if that is enough in itself to require a swap. I have the part if necessary, just need to get it up on a ramp and get medieval on it's ass!

Does anyone have any suggestions? I can get whatever info is required from the Nanocom, I just wish you could tell it to "dump everything" to the SD card from Motronic, but if it does that I haven't found the option. Personally, I'm leaning back towards MAF again.. but I don't know these engines - yet 🉑

*I really suck at this :( I couldn't fit my hands far enough up the gap to get a decent grip on it, and I wasn't strong enough to do it with fingertips.

But at least you'll know there's nothing worn out!!

Heh, funny you should mention that hose - I just bought some to replace the slightly dribbly one we spotted at Summer Camp. I don't know if it will cope with the bends without elbows, but I'm going to give it a try before ordering up extra bits.

And now I realise that it's 10mm for that pipe and not the 8mm I ordered! Bollox :)
Ah well, it's pretty cheap!

It could be rich....but I'd go richer first just to be safe.

Hmmm. sounds to me like a roll of Kunifer and a couple of flare tools would be a good addition to the next RR meet!

Ooh good spot! Purchased :)
Thank you very much. I'll swap that over next week. I hope the nanocom wasn't doing the same thing with swapping the fault code over as it does for the ABS Sensors! Although, it's too late now - the old Bank 2 sensor is long gone.

I'll give Simon at LPGCCccc a bell and make sure he's available to do the tweaking once the petrol side is sorted.

Apart from the cost, this won't be damaging to the engine will it? I've got another long trip this weekend. I can take the Jeep but the Rangey is more comfortable.

EDIT: can a mod split this thread? I don't want to clutter this LPG thread with my engine woes :)

Curses! I reset the adaptation values at lunchtime and went into town and back. Adaptive values out of range for both banks and O2 sensor fault bank1 upstream. Not much point getting it re-mapped until I change the other O2, I guess. Still, it means there's probably more to come :)

I've done this before too a few times, usually after tinkering with the dash and then wondering what the hell I'd forgotten to plug back in!

At least the battery works in your siren ;)

Yep! and it's B**£$Y loud with the bonnet open :)

I've used Mintex before on my Jeep and had nothing but good things to say about them. Glad they're working for you, but it's probably down to those stainless bolts on the brake shields! :)

I'm a bit gutted because we were regularly seeing 240 from a tank (74l useable volume) before I changed the upstream O2 sensor on bank 2. That would mean a rough average of 3.2 miles/l which seems consistent with what you guys are reporting.
I noticed some adaptation out of range errors when I was messing with the nanocom tonight and another O2 sensor error for the other upstream sensor. I'll recheck in a couple of hundred miles and see if they come back. No misfires this time.

Yep, I need to do a proper brim to brim from the same pump comparison but at the moment I've measured 2.8 and 2.9m/l from different fillups between different pumps (140m/50 litres and 205m/70 litres approx)
4.6 and multipoint

Maybe the drag will reduce now I've had the tracking sorted :)

Ahh the love and support is strong :)
I still don't understand how she managed to set the alarm off... but everything's connected - right?

Simpler than that!
Sorry for the false (ish) alarm. Once I realised that it is supposed to crank when immobilised it all became clear.... she had left it in drive and I didn't notice.
DOH!!
So, whether the EKA reset was necessary I don't know... once the alarm shut up and it was in Park - order was restored.

So glad we hooked up the siren again :evil:

I'm not allowed to beat my wife, it's her birthday. Well, not enough to hurt!

Help!
My wife was driving and after returning to the car she said the alarm sounded when she tried to start it. I don't know if she locked it. Possibly not.
Now I can operate the door locks with the fob but the engine won't crank. There's no eka warning on the dash. I tried Eka unlock via the nanocom but no change.
I also (foolishly?) tried to unplug the siren and found out is IS battery backed...

Is this the loss of sync thing? Is there anything I can do?

Well that was a laugh :-) nice to meet you all and thank you for being so welcoming. I was very glad to cook, I'm very little use with a spanner (unless it needs cleaning)

I've now got working Cruise Control (thanks Richard!) working ABS/TC (thanks Marty!) and I've got a few things to look at to maybe get a step ahead - starting with tracking!

Special mention to Chris for explaining things slowly and carefully for the hard of understanding ;-)

I'm also much happier with the EAS which still had a mind of its own but at least it isn't as likely to strand me as I first feared....

I hope Mark got home without having to sit on a stool. I felt a bit guilty (well, maybe a tiny bit) leaving first but the run back to Yorkshire was pretty smooth and I was back by 1930.

So, thank you Marty for organising a really fun scrap moving... Err... P38 party weekend and I'm all up for another one sometime! Now, I just need to go and polish that collet....

I'm in Quorn which is about half way, with a couple of dozen sausages from the Farm Shop at work, a portable BBQ, a load of buns and a token few tools. I'll pick up some charcoal en route and try to reach you guys by noon(ish).

You don't make friends with Salad ;)

I'm back on :)

I went out to test the compressor and thought "I wonder if...."
So I rammed the hoses into the dryer and she popped up! As soon as I let go, the hissing started again. So I'm going to leave her on the level overnight and if she's still in "Normal" position in the morning I reckon I'll be able to get to summer camp. \o/
If the new dryer arrives in time I'll have a bash at fitting it, if not I'll take the relay out and drive down in one position all the way. I don't want to take the chance of the compressor running for hours at a time.
So today went PANIC PANIC PANIC check on forum -> fixed. Thanks guys, really appreciate it!
