    Default al4/dh0 question

    yes i am still experiencing problems with my "auto" light.

    my question is: what of the transmission is engaged while the car is in park?
    reason: the auto light came on soon after the car was turned on and still in park. upon this occurrence there was a strange sound (whirring?) in the engine bay. of course i turned her off and restarted.

    any clues?

    Has the gearbox had its solenoids done and a software update?

    What about oil level checked? Start with the basics.

    Yup very recent. Also inhibitor switch.

    Oil pump. Hmm...

    I'd be surprised if it were the oil pump.

    The fault readings are of interest.

    fault readings have thus far lead down the road of replacing parts that dont need replacing... just after ideas. last code btw was speed sensor

    Output speed sensor?

    Inductive sensors are easily tested, line pressures can be tested externally. It's rare for these items to fail, and I am concerned you paid for stuff that should have been more fully tested.

    Have you heard the noise made by actuation of the electrovalves? It's quite strong.

    http://www.audiocheck.net/audiofrequ...squaretone.php - select a 100Hz square wave of five seconds or so duration; open the file (not save). (You can also listen to a 50Hz one, to make sure the software was upgraded.)

    Relevant, too, is alternator output quality (the beginnings of failure may include obstructive waveforms) and overall underbonnet connectivity. See recent posts by "shanadoo" for this detail as found on PSA cars. I am not familiar with the Renault fuse/relay panel but it's unlikely to be from another planet.

    Yup the software was def upgraded. As for the rest of what you said, its all Greek to me.

    Would poor alternator output create a situatio where the auto light would come on?

    Yes I think I paid for repairs that didn't solve the problem. Seeing that a code came up for a short to pressure solenoid. Maybe there is an electric short somewhere from said solenoid back...?

    Thinking of getting electrics checked by an auto electrician.

    The fuse/relay panel, that's the one in the engine bay not the regular fuse box hey?

    I have the same short to positive faults on my AL4, and they're false.

    You can check this with a multimeter across terminals at the ecu plug, noting the resistance.

    I think its software phantoms. Nothing you can do except replace the ecu - it cant be reflashed, just updated. If there are no more updates but it has faulty software, you have to bin the ecu...

    I'm sure that somewhere there is a person who can re-virginise the ECU. Be nice to know who they are.

    If its a bad ecu maybe a second hand one reprogrammed? Ya reckon its the ecu?

    I'd start with connections. Also, find the earth points for the loom and ensure they're good - engine bay and inside the cabin.

    The parts specified in that post, what are they and what do they look like?

    The underbonnet fuse panel is typical iPad/tablet size, usually under a cover and near the battery.

    Primarily it contains a bunch of smaller size relays that are controlled by the in-cabin electronics, in conjunction with some electronics of its own.

    From this panel, many aspects of the car's operation with heavier current draw are regulated. These include headlights, wipers, drivetrain starting and running controls, and vehicle dynamics. As Shanadoo describes, poor connection inside this part of his C5 was greatly compromising the transmission's ability to behave nicely.

    I had a quick look in the dark and all seen secure except one fuse (dont know what the fuse is for) which was a bit loose so I pushed it in tighter but I can tell the socket the fuse is in is just a tad loose still....

    *shrugs*

    al4/dh0 question-imag0401.jpg

    ok this is the fuse box in the engine bay next to the battery. the fuse that was a little loose it circled in green and the plug that i unplugged and plugged back in for no real reason is circled in red.

    no auto light was recorded this morning on the way to work (50km) where as previously it would come on once or twice... relevant? i dont know....

    It's a bit like someone trying to grab your bare arm, but they grab your shirtsleeve instead. That's sort of what can happen when electrical conductivity is poor. The physical looseness or tightness of the fuses, isn't much of an indicator in most cases. Sometimes, the amount of metal touching metal was just inadequate after a few years ageing, and the giveaway has been a maker changing to more durable attributes like gold plated connectors.

    Here's a Pug/Cit one: http://www.ebay.co.uk/itm/280915763944 This is a unit of which type I have personal experience of being faulty in hidden ways. It looks like in the background of your photo there are similar relays in the fusebox, so that is probably the corresponding part of your Clio.
