Engine Management light
Discussion
Hiya guys
Having Issues with my engine management light, it keep's coming on (Staying on for a fair while) then when I leave the car for a long period of time it goes off, I've taken it back to the dealers 3 times now and had them reset he Ecu but there's obviously something wrong as it keep's coming on. There's no pattern at all as sometimes it stay's off for 300 or so miles and then comes on, however last night when I picked the car up for the 3rd time it came on after less then a Mile ? there doesn't seem to be any change in performance but this is beginning to really bother me & Mrs Boggy
Any one else having this Issue with there R/S
I want this resolved

Know how you feel, mate - I had the same issue a year ago. Had to keep going back to B&C, with a 100-mile round trip each time. Even with the warranty it was costing me in fuel and wear and tear.
You need to have a go at the dealer - Lotus usually ask them to do the cheapest fix possible and normally it doesn't work. In the end they replaced my ECU but I was so annoyed with the process (and a couple of other issues) that I changed to a different dealer for servicing.

Weird....Sunny day today Car out, just filled her up on my way back to the office Engine man light comes on, Only had it in the dealers last week for the same thing. Twice in 2 weeks!!I cannot get it in until Monday, plus time out plus cost etc car is only 3 months old.Is this common? or is someone up there taking the piss?

Hiya
Here's the response from Seloc
(Get your dealership to check the engine compression ratio, some are coming out of the factory higher than they should be (and with no explanation as to why).
--------------------------------------------------------------------------------
I think you mean do a compression test as the compression ratio can't be calculated easily without taking the head off the engine. That'll most likely be down to differences in combustion chamber castings.
I would have thought the P number would be a good place to start, though its probably worth your ECU being programmed to the latest Lotus factory standard... I'm sure there's a factory bulletin which sounds a bit like your problem - will have to search the archives though..

Sounds to me like a Toyota-specific issue. Mine was a VVC temperature sensor and the whole circuit was tested to no avail before the reprogram then replacement. Best get Wilsons to check that out on Saturday then hopefully the extra time needed will allow you to explore most of Essex with that Exige S you'll be driving 

I had this exact problem on a 111R. Here is what Lotus suggested to the Dealer, dont laugh, because it worked.
Run the car to just before the Cam switch over in 2nd gear and then coast to as low as the car will go remaining in 2nd gear. Do this 3 times.
Next from when the engine is cold e.g. first thing in the morning. Start the engine and leave it run until the Fan cuts in to lower the temp. Allow this to happen for as long as it takes until the Fan has cut in at least 3 times.
Thats it. I was getting my MIL coming on almost weekly at one point, the above sorted it. Problem for me was that the 2 scenarios were given to me about 2 weeks apart, so was still happening for me until the 2nd scenario was performed.

This all sounds to me like a faulty Ecu, and by running these fixes it's resetting something ?

Had the car in this morning ref the man light, told them about the compression (cheers Boggy) but apparently their mechanic had been to lotus on a course and there is problems with the throttle linkage, and they where publishing new software for the ECU which would need to nbe uploaded. Left the car there for them to sort out.Not a happy bunny
Suggest this will not be the last i hear of this. Pain in the arse taking the car in etc etc.
Saw the new Exige, very nice!

Very Very un-happy,
The engine management light has come back on again while driving at low speed's on Saturday, it's going back in tomorrow and I don't want it back till this is resolved, I can't believe this it will be the 6th time back to the dealer's I'm starting to wish I hadn't brought this car it's been a pain in the arse, the worst thing is I probably could have brought an Exige S now if I hadn't upgraded to another R
I think I need a little confidence re-installed

Makes ure they contact Lotus HQ. I has exactly the same issue on an R. ECU was upgraded a couple of, what seemed little tricks, and all was sorted.
If you want more info, let me know and I'll post, but its long winded and my typing's Cr4p
Nice one thanks, I don't now why they didn't contact them after the 2nd time as they've now pi**ed me off

HI Boggy,Hope you get sorted soon , Glad to say my car is running as well as ever (Seems to run smoother?)since my new software was loaded onto the ECU, very happy Bunny, now looking forward to Easter, Tops off Lads!

Boggy if you want to call me email me your number via my profile and I'll ring you back. Wont be until the evening as I can not access my personel mail from work
Nice one !
I've dropped my car off at Wilsons this morning and they've got the guy coming down from Lotus who's dealt with the problem before, I'll wait and see what happen's but I'll pass on my number just in case
Thanks in advance for all your help on this guys

Its Error P1302
And apparently it's being caused by my Quicksilver pipe
I don't believe a word of it as everyone I now who has an R has a Aftermarket Pipe? Wilson's fit Piper cross induction kit's thereselves this sound's like a total cop out to me, what am I meant to do re-fit the standard pipe or buy a stage 2 from Lotus ? this sounds like there just trying not to fix the problem

Number 1 mate, keep your cool.
Suggest the following:
- Wilsons will download the latest map to your ECU and see if that fixes it. If so, great, if not...
- ...ask Wilsons to refit the standard pipe as a part of the investigation and see if that fixes it. If it does, then that's the QS item out of the equation and you have to find a use for it.
- If putting the standard pipe back on cures it, then I would discuss with Wilsons/Lotus that you intend to purchase which ever Lotus Sport pipe you prefer (from whoever) and get that fitted. Your expectation is that the MIL problem will not re-occur.
- Explain that if it does re-occur, your expectation is then that the problem is not caused by the Exhaust but by something else. Your expectation at that point is that Wilsons/Lotus (whoever agrees) will then refund you the full cost of the purchase and fitting of the Lotus Sport pipe, and refit the standard one back onto the car for you.
Get everything in writing and keep a log of ALL correspondence, telephone calls etc. you have with everyone.
Hopefully it won't turn silly and you can sort it out amicably.
