I'll take the seat runner please - will BM you in a bit....

I've made changes to the injector scaling as suggested here (and by emerald) and whilst the tickover isn't as lumpy it's still running rich with the exhaust chucking out black smoke when the throttle opens. I'm giving up and booking in to emerald for a mapping session as soon as I've decided between investing in a new silencer or verniers.... Thanks for the suggestions anyway!

Thanks for the info, I'll have a look at it again with the suggestions made when I'm allowed back down the garage Mark, it's non vvc on a plenum with 52mm throttle body and has blue injectors (think I've read about straw coloured ones but I'm getting confused!). Don't know what cams are in it, didn't ask when I bought it and haven't thought about looking in the last year! Is there an easy way to identify them?

Right, I finally got my EU3 to EU2 adaptor wired up and the Emerald fitted to my car along with an LC1 wideband lambda. I've used the base map supplied and followed the manual for the TPS & IACV setup and also made the changes to the AFR range as recommended. Good news is the car started, but it runs a bit lumpy and smells like it's running rich plus there's a fair amount of smoke when you open the throttle. Given my lack of knowledge and understanding I've not got a clue where to start in making it run better - I wanted to get it running ok before going to a rolling road so I'd not be wasting time fault finding etc. I'd be grateful for any advice or knowing whether there's a better base map around I could use. Cheers, Karl.

There's a VAG-COM section on the uk-mkivs forum - could ask their advice on there or take a look at their VAG-COM user location list....

Cheers, I may as well have a go and see what I can do - at least it's not something mechanical I can screw up Will BM you re payment.

May be a daft question but will the tonneau fit my S3 with cage? If it will I'll take it please.

Spotted a red 7 with reg starting W888 coming off the Ann Summers roundabout in Whyteleafe aroun 1130 this morning.

Silver with burgundy arches spotted in the queue for P&O while we were getting on to our sea france boat. Was about 1300 French time.

Saw 2 on my way back from the delights of Bognor this afternoon: 1 black, had a full cage and a reg that began R300 around 1515 on the A29 between Arundel and Slindon 1 yellow at 1530 just going into Storrington

John, I've got a bleed tee sat in the garage doing nothing at the moment - you're welcome to it. I may even make the Plough tomorrow so could bring it along if you like. Karl.

Spotted by the wife at 1500 at Reigate hill..

Certainly sounded like there was a collection of nice cars down there. I had a call from my father in-law asking if a westfield was the same as caterham

Spotted tonight parked on Poole Quay with lots of other nice cars by the in-laws - yellow with black stripes on the bonnet.

I always thought the MEMS and 5AS were paired and you couldn't run the MEMS without it - but then again I'm sure someone has a more definitive answer than me! I did a quick google search and there were some mentions of not neeting one of the plugs as it was for diagnostics but I'm guessing you've tried it without the one that doesn't plug in anyway. I found a spreadsheet with the pinouts in case it's of any use going forward. Karl.

I wonder if you could borrow an ECU (& immobiliser) to give it a try? Good idea, I'm beginning to think it is a faulty ECU now - guess it means I'll have to bring forward the Emerald purchase if it is :-) Not at home at the moment, but I am sure my k-series idles at around 700rpm when warm Thanks Ian, I had a feeling it was around 850 but it's been a while since it worked properly and my memory's not what it used to be

Fred, Well, the problem is it never used to tickover at 1500-2000rpm (or hunt between the 2), was always around 1000 so I don't consider it to be normal now. Plus, when you're slowing down for a roundabout or traffic (for example) the revs drop for a moment then pick back up so you start to speed up again if you see what I mean. Karl.

Thanks for the info Paul. The air filter is clean and doesn't seem to be blocking airflow, it's not a plastic manifold so it's not getting distorted either.

Roger, I'm not convinced the Lambda sensor is the problem but don't know and am a bit loathed to spend the £80 (or whatever it is they cost) for it to be another thing that makes no difference! Then again if it's bust I should probably get one anyway - where did you get yours from? Karl.

I've mentioned on another thread some idling problems with my EU3 1.8 K series - it starts up fine and sits at 2000rpm, then drops to idle at 1500. When warm it idles at around 1500rpm but does eventually drop. I thought I'd have one more go at using the wisdom of blatchat before trying to arrange something with the contact Coyoteracer11 gave me! So far I've: 1. checked for a sticking throttle cable 2. checked IACV,TPS and MAF plugs and wiggled the cables 3. swapped IACV 4. swapped TPS 5. swapped water temp to ECU sender 6. swapped MAF 7. reset the ecu using that ignition off, 5 times on throttle procedure at after each of the above 8. Revs drop if you pinch the pipe going to the IACV so I assumed that rules out an air leak in the manifold? I passed an MG Rover place the other day and got them to plug it into their Testbook diagnostics machine. The only problem found was with the lambda sensor where the value gave a constant reading rather than what the bloke expected to see which was for it to fluctuate - does that sound right for those who know? Every other sensor was working as expected and there were no faults reported. What I couldn't work out was whether (or how) that would cause the engine idle problems, could it have that effect? I don't really want to pay out for a new lambda for it to not resolve this issue - although if it is bust then I may need to get one anyway. If anyone has any other opinions on what it could be or what I can try next please let me know as it's really beginning to annoy me now Oh, and if anyone has a spare lambda in the Bromley/Croydon area (or Bournemouth as I'm here until Monday!) and doesn't mind me borrowing it to see if it makes any difference I'd be very grateful. Cheers, Karl.

Plug it into Testbook or an OBD2 reader and see what the sensors are saying to the ECU. I was going to see if there was a local garage with some kind of reader but thought someone told me MEMS readers were few and far between. I'll ring a few places tomorrow. Ta.

Not wanting to hijack this thread but I've got a similar problem in that my EU3 1.8 K series idles fast on start up (2000 rpm) and then ticks over at 1500. It will eventually drop but as soon as you're on the throttle it's back up to ticking over at 1500 when you stop. Having looked at this and some other threads I've so far done the following which has made no difference: 1. checked for a sticking throttle cable 2. checked IACV,TPS and MAF plugs and wiggled the cables 3. swapped IACV 4. swapped TPS 5. swapped water temp to ECU sender 6. reset the ecu using that ignition off, 5 times on throttle procedure at after each of the above The only other thing I've read about is the MAP sensor, but given my limited technical understanding I think that basically means the ECU is screwed - is that right? Is there anything else I can try? Cheers, Karl.

Grey with orange band on the nose - reg was R500 T?? hence me guessing at it being and R500. Was outside my house near Balgowan school - couldn't get out quick enough to catch you before you shot off down the road!

Well, I'm thinking about Emerald so could do with one of these - if there's still one going after Rullingen has had his pick let me know!

Spotted about 1615 this afternoon, blue with hood up.
