    Good point, I was wondering about mentioning it or not. I was worried that they may notice the map when running a scan...

    It was a remap file, so no tuning box, and as you say the ecu should be told of the adjustment. I have noticed it is running pretty flat, a jetta 2.0 TD pipped past me at some lights (both from stand still), which shouldn't happen... not that I'm in the habbit of racing or anything.

    I mentioned the car felt flat to the company that remapped it, but they kind of fobbed me off, I should of took it somewhere they do a dyno and map so they can tweak and optimise the map!

    They probably will spot the map, although you can just plead ignorance, say the wife must have put it on for your birthday.

    There's a good chance they might flash it back to standard too, as they'll probably look through different sensor readings, spot the different fuel pressures and injection amounts and try it as BMW intended to see if that fixes the problem.

    It's worth having a quick chat with your tuner guy, ask him about the problems, and see what he/she says, and if they will put the map back on afterwards if it is removed.

    That's true, could say it must hae been on there when I bought it. I'll email the fault codes to the tuning company, and as you suggest ask whether they'll put the map back if it is removed.

    I'll get BMW to look at the fault with my blowers at the same time! I've tried everything I can think of, but still no joy!

    4B10 – Smooth Running Regulation – Correction Quantity Too High
    41F2 – Electric Ventilator - Activation Interrupted
    4212 – Cylinder 1 – Activation Interrupted
    4242 – Cylinder 4 – Activation Interrupted
    4B37- ?????????????????
    3EFC - ???????????????

    IC:
    A3B3 - ????????

    I managed to translate some of them online (as the diagnostic tool doesn't tell you the fault definition), however some of them I couldn't find...

    Does anybody have a list of codes for the E87 (1 Series)?

    Also, does anyone know whether a combination of some of the above could point to a faulty fan motor?

    I have had my car remapped, so was expecting to see some fault codes (as the re-map generates some codes - so I believe).

    Thanks in advance!

    Paul
    Just an update on the fault code definitions:

    3EFC "Thermal Oil Level Sensor"

    4B37 "Oil Condition Sensor"

    I also got some nee codes (had a diagnostic ran with a Launch diagnostic reader). These were:

    9C49 "Hot Air Flap Motor, Right"
    9C53 "Electric Auxiliary Heater"

    And then 5 other undefined codes:

    [0,1,e7,17]
    [0,1,e7,1a]
    [0,1,e7,20]
    [0,1,e7,1b]
    [0,1,e7,14]

    I've had the map taken off my car and the code 4B10 "Smooth Running Regulation - Correction Quantity Too High" has gone now...

    The tuning guys were really helpful, and said they'd put the map back on free of charge when I've had the car looked at by BMW.

    Since I've changed the glow plugs and had the re-map removed I now only have the "Thermal Oil Level Sensor" and "Oil Condition Sensor" fault codes. I presume that this means that my oil level sensor (located at the base of the oil pan) is faulty.

    Not too bothered about this as the oil isn't that old and the levels are ok after checking manually.

    My question is should I have the re-map put back on? It would seem that since it was removed the "Smooth Running Correction Quantity Too high" fault has gone, therefore was there a slip up with the remapping process???

    Have a word with your tuner, tell them the remap has been causing a smooth running correction error and see if they can adjust it to suit.

    You've paid once, and it should only take their time to make a few adjustments until the problem goes away.
    Even if they don't make the files themselves, they'll still be able to contact the original tuner who will be able to sort it out.

    I would have thought that not only it wouldn't be a problem, but if it were me for example, I'd like to know of any glitching as soon as possible.

    There are 101 ways to tune a diesel, usually ending up with similar results, and it seems they have just come across one that is just a little off with your car.

    Cheers,

    They have been good so far. When I contacted them they came and removed it and said they'd put it back on again whenever I want, however they would not admit that it was a fault with the map.

    Although the error disappeared once the map was removed, so I suspect there is a link.

    This is why I'm reluctant to get the map put back on. I wouldn't have any problem with them if they were to hold their hands up and admit there is a glitch, but with the blame culture these days I can understand why they wouldn't want to do so.

    I'll ask their advice and see what they say.

    I appreciate your comments so far since I understand tuning is your business!

    Cheers,

    Paul

    Well I don't suppose anyone likes to admit they are wrong, but being sensible about it and taking all claims seriously should be paramount.

    It may be entirely correct that it's not a problem with their map, but for example a minor difference in injector flow that can be "adapted" out under normal circumstances, but under tuned conditions is just past what it can pull back on.

    There is smooth running tests that can be done, and with good diagnostics, there should also be a view of how much it is adapting each injector to get perfect results.
    It's possible that you may have one just on the edge of causing problems.

    That's true, so the tolerence on the injectors possibly decreases due to the extra strain of the tuning.

    Can you clean the injectors out with anything?

    Cheers,

    Paul
