So as per my other post I've had the EML come on. Today Davis Motors turn up and read 2 error codes, the first one not readerable and the second is code P1271, I believe from a search on here that it is a Throttle Body code / problem. Now my question is this. I got the car 3 months ago from Christopher Niels in Northwich if it is the Throttle Body would it be covered under the Warrenty? CN have said they are happy to recieve the car for them to have a look at, if the problem they find is covered under the warrenty they will fix it, but I always have this feeling I am going to get screwed. So what should be covered under warrenty when you buy a 2nd car from a dealer? Regards GiGo

Not sure what's covered, but if it turns out not to be I've got a spare tb that I could drop over at cn's to see if it fixes it. (I only live 10 mins away)

Depends on the terms of your warranty. I'd guess the throttle body would be covered but warranties have so many get out clauses, who knows? Probably not going to be the throttle body anyway and more than likely will be the loom of doom or more accurately the plugs and sockets behind the expansion tank.

Um... sounds costly :( Any idea how much it would cost if it is just that? I just don't want to be ripped off!


mscall thanks for the offer :D I was up that way yesterday visiting my brother, I was rather glad the VX was not running, the rain was terrible.

Usually free. It's more often than not just a case of unplugging them, cleaning them with some contact cleaner and making sure all of the pins in the plugs make decent contact when plugged back together. Also worth doing the same with the connector at the throttle body and the throttle pedal but it's mostly the connectors behind the expansion tank. Just a case of removing the nearside rear wheel and arch liner to get best access to them.

And get verification before they do anything. I got a 1635+1271+1220, and they put in a new ecu, of which still today i'm not sure was needed.

I'll make sure I get the all the codes first & confirmation of what they want to do to it.


To fair to Christopher Niels they have been (so far) very good.  I rang to see if the car had been delivered and I was told they were just unloading it and it would be looked at in the afternoon or the morning & to ring back tomorrow lunch time for an update. So far so good.

I will probably mention that the Mrs is looking for another car (because she is, but might not be a Lotus) and ask them about one they have on the forecourt in a hope of getting some better customer service,as I would think (if I were them) 'if he's happy with our service he'll bring the cash for another car'.

Cheers for the help guys & girls.

Holy thread resurrection.... Just started the car (after a weeks lay up) having washed it and it came up with this fault code P1271 and was giving no throttle response. So opened the boot and had a quick wiggle of the connector block onto the throttle body (next to the air intake pipe) cleared the code and restarted the car. EML had disappeared and the throttle working perfectly again... Will have to keep an eye out for it happening again, but thought this may be a worthwhile post for someone searching this fault code in the future. thumbsup

Yeah clearning the codes worked a treat, for 30 miles or so, then it happened again thumbsdown Turned out it was the throttle peddle box, box out and cleaned/greased connectors and good as new thumbsup Forgot I never updated the thread to say what the outcome was.

Well I shall just have to keep an eye out. thumbsup.

But to be perfectly honest it is just sitting in the carport at the moment with the occasional trip out. Worst case scenario is I shall have to give the AA a call and use my 'Repair Cover' if it all goes wrong.

Yeah I've made use of my AA cover in the last 6 months, lovely chaps, well most of them. Let me know if the problem persists. Will be interesting to know if it's the same problem.

Well today washing first day when the VX got a proper outing and bish-bash-bosh P1271 again. Fortunately turning off and restarting the car got it going again. However it kept bloody doing it on my way home... Scanguage only lists one Fault code P1271. Now I had expected there to be more than one... Or does the ECU only retain one listing of an identical fault code? Of course I packed the other car back up north with the missus yesterday so will need to do some diagnosis and rectification... So after reading Nickb777's thread I will have a look at cleaning up the connections on the harness first. At least the car got me to the Leeds Dental Institute for my session today, and observed by Ofsted this afternoon. Karma I guess

Been out to the car - the plastic bracket that holds the conector blocks behind the coolant tank had partially uncoupled itself from the coolant tank bracket - so the fact that the problem kept happening over bumpy surfaces could point to this being part of the problem. Just another day in paradise! Given the connector block on the throttle body a quick clean and plugged that one back in. Will repeat with the block behind the pedal and coolant tank another night this week. Am too knackered to attempt tonight and likely to do more harm than good.

Um... this problem did start with me turning the g/f and saying
'It's fine over speed bumps, don't know what people moan about'

Only had the EML on twice since this whole problem. Not sure why it came on, but both times was after a good 2 hour drive.

You'll have to put up a guide to cleaning the connectors Mangham54!

I doubt it is necessary... But will if it seems worthwhile!

block behind the pedal


Thought I put this in my last post.

This is what the garage did to mine. Cleaned all the connectors and it's all been good since, fingers crossed.

Tonight is the night... For tinkering! Just been into a local motor spares... Asked for contact / dielectric grease and in his wisdom he suggested Contact Cleaner (already got somewhere) and then WD40?!?!?!? "As that leaves a coating after spraying" - a coating of what? Fairy fcuking dust I can only imagine. So gonna try Hellfrauds on my way past, but wouldn't be surprised if either they don't stock it, or the dickwads at my local store haven't got a clue! If not fcuk it. It'll just have to be contact cleaner and WD40 as suggested. I'll get some pics as I go along in case they are any use to anyone! Could really do with getting to the bottom of this tonight as the VX is back go normal duties as of Monday when the MG is left with the missus for her final assessed placement.

How the fcuk do you unclip the throttle sensor. Quick response required as I am laid in the footwell and it is cold!

Pull back the little grey part backwars about 1 cm.
This frees up space for you to press the black part down, that then unlocks a plastic hook as you can see on picture 2.
Then just pull off the connector.

Woops, sorry, just reread your post about the footwell Posted Image

Pull the red locking section out - comes out at 90 degrees to the main body of the plug - and then pull the rest of the plug straight out.
