    Transmission Error Codes Audi Q5 2012

    Hi,

    For a few weeks now I am getting intermittent an error message when starting up the car, a 2012 Audi Q5. It says on the Dashboard

    "Gearbox malfunction - You can continue driving"

    This goes away after a few seconds and won't come back while the car is turned on. A few days ago I went down a gravel road and the message came on and went away several times, right after this during the same trip back on a normal road the message did not come back all day.

    Any ideas ?


    Here is the scan from the car

    There is a TSB on the oil control valve that allows oil to flow through the cooler (on the Q7, at least). It requires a new valve and loom extension.

    Q5 Gearbox malfunction - cooling valve

    Hi As well as checking out the valve and connectors, I would suggest you first check the transmission oil level, followed by 16 way multipoint connnector cable plug and socket on the transmission for signs of corrosion/water contamination. if the level is OK and NO signs of water contamination/corrosion at the cable connector, I would follow the suggestions on the TSB.

    If there is light corrosion, clean the connectors and retry, if it's heavy with signs of radiator coolant, clean as best you can and follow the full transmission service suggestions below. If this is the first occasion of alarm, even though there may be light corrosion, it's unlikely that the transmission oil will be severely contaminated, in which I would suggest carrying out a calibration of the transmission, with transmission temperature between 40 and 60C. If however, there is heavy corrosion at the plug and the problem returns after replacing the valve, then suggest you carry out a full transmission service, changing the oil and filters, followed by a further calibration.

    A quick and simple way of checking if the transmission oil is badly contaminated, is to remove the black plastic collar around the transmission ECU, where the multipoint connector screws into. To remove it, firstly remove the multipoint cable plug. There is a single screw locating the collar, remove the screw and turn the collar approx. 1/4 turn (Anti clockwise to what I can remember) and pull the collar out. If the oil is badly contaminated, there is likely to be a white sludge build up around the bottom of the collar. If you find this, carry out a full transmission service, making sure the pan is removed, washed out and both filters changed. Just changing the oil and filters, will NOT fully clean the sludge out of the transmission.

    Hope the above is of help and good luck

    This goes away after a few seconds and won't come back while the car is turned on. A few days ago I went down a gravel road and the message came on and went away several times, right after this during the same trip back on a normal road the message did not come back all day.

    Any ideas ?


    Here is the scan from the car

    First, Thank you so much for your message and time invested

    Today I did a check on the connector, all is clean, dry and there is no corrosion. For this I had to jack up the car on one side. Then I went to a friendly place where they change oil and had them check the oil level in the gearbox. This also was fine. Yesterday night I erased all the codes and during my drive to the shop no warning message came on, however, when they checked the oil level, the guys there asked me to turn on the car and right there, the message came back. After this I went to another shop specialized in transmissions and the owner there had this own diagnostic computer hooked up to the car. The memory showed the same error / codes from the day before and when we went into the values of the oil cooling valve, voltage and temperature showed both fine.We could even see the temperature going up and down a little as the fan from the radiator kicks in. The temperature was around 85 celsius. The transmission guy is really good I think, he did 2 transmission for me before, not on Audi. He told me that this could be an intermittent error and I would have to come back wednesday morning to drive the car around with him looking at live data.. It was to late to do this.

    In your post you mentioned to check out the valve, how can I do this ? I understand this is inside the gear box ? Is this correct ? I have been browsing the web but couldn't find anything what I can understand. Is there a way to adjust this or measure the valve with the VCDS software ?

    Thank you again

    Hi and thanks for the update. No, this is an external valve which is usually on the RHS of the transmission. It is a black plastic valve ,which diverts water through the transmission oil cooler. You can identify it by the 3/8" water hoses and the 2 wire electrical connector. I don't want to sound patronizing, but the transmission oil level (specifically the mechatronics section of the transmission), is being checked on a level surface and with the engine running and level plug out ? - if in doubt check out on-you tube. Good news that there is no corrosion at the multipoint connector, but would double check 2 wire solenoid (cooling) valve. Also check the transmission wiring loom connectors for possible dry connection.

    Hope this helps

    Good luck

    Thanks again to everybody

    Here is today's update.

    This morning I went back to the transmission shop, they hooked up their computer again and we went for a long drive, uphill, downhill and so on, but there was NO CODE whats or ever. Yesterday night, after several Gearbox messages I hooked up the VCDS again and tried a few things. First, the moment starting up the car, the messages appeared, then I cleared all codes. Second, the next start up, there where no more codes on the dash but I did still a scan without having a message and the Scan revealed the hydraulic pressure error, but only in the software, not on the dash. Then put the car in gear and the gearbox message on the dashboard came right back together with the Cooling oil valve in the software. So, now it is clear that the Cooling Oil Valve is causing the dashboard message. At the shop today, the guys there are sure that the cooling oil valve is an error caused by the 0B5 DL501 Q5 Transmission Circuit Board. They think a weak or lose connection there is the cause and the board will fix this guaranteed. They checked live temperature, volts and god knows what else but all was fine. The valve indicated in the Thread above is external, probably an easy fix if it would be bad. Now how can i be sure ? The tranny shop is really good, they do only transmissions and on all fancy cars, I know them for years, they fixed cars for me before, warranty their work and so on. However, I don't trust them 100% !

    Now here is the kicker, yesterday after all that screwing around with the car, lights on and such, I thought I hook up the charger to the battery, to make sure the battery is fine, I had some bad experience before. I have a fancy smart charger for AGM batteries, the car has a Optima Red Top installed. Right away after the charger was connected, the display showed only 51% of charge, no problem there, I left the charger slow charging all night and the battery was good this morning. All morning, running errands, doing the diagnostics I had no error message ! Could it be that low battery voltage caused all this ?

    Can't be ruled out, but I doubt it.
