    Successful C7 0B5 Clutch Calibration MY2013

    Just a quick note to say I followed the clutch valve and distance sensor calibration (basic settings) on MY2013 C7 Avant with 0B5 DSG transmission without problems.

    http://wiki.ross-tech.com/wiki/index...rbox_(DSG/0B5)

    The car had started giving the odd thumpy gear change - especially moving away from stand still and when cold sometimes into 2 or 3, but was increasingly doing it occasionally when warm so I rolled the dice on this procedure and must say it has been a massive improvement based on a short test drive. Need to drive it from cold before completely happy.

    Car has ~95k miles and is up to date with dealership DSG oil & filter changes. The TCM never threw up a fault code before or after the procedure.

    For the record, I did the procedure with VCDS 19.6 and I think the TCM was updated with latest software last time it had the DSG oil serviced. I will post up any relevant part number details later if anyone else needs additional confidence boost before doing this.

    No worries -- moved.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    I've got some worries - less than a week after reporting a magic cure for clunky DSG changes, it seems they are creeping back in again. No fault codes of course. Gonna have to look into some ways of determining root cause of problem so thats gonna be fun (not) - fully expecting to find out the worst on this super complex transmission.

    Mech. Unit HW: 0B5 927 156 F is considered as a "bad part".
    There is TPI for that unit where 3 solenoids are replaced, but only if they give fault code. RoW: TPI 2039534/12


    From my personal experience You should try software update from dealer/3rd ODIS party using testplan option for DSG clutch check. It does automatically software update and then runs clutch wear index test. It relieves a little bit the wonky gearchange.

    In my opinion the real issue is the mech itself and oil pressure valves inside. There is a repair kit for sale where You can drill them to bigger size and install oversized valves. Other option is to install whole new mech.

    Depending on mileage the clutches themselves can be a issue also.

    Seems I have the ill-fated mech unit that you called out !

    The TCU had a s/w update with the 2nd DSG oil change last year. I have ordered up an SSP429 from erwin and will have to swot up for a while on that before I can start to even talk sensibly about it. I have seen other threads and forums discussing faulty solenoids. Only have 100k miles. Also interesting about aftermarket over-sized pressure valves.

    So an update - a week ago - Friday 13th no less, the car starting making more heavy ugly changes - particularly pulling away from standstill and coming to stop, but occasionally some other gears. I wasn't driving at the time, but apparently it lit up like the proverbial xmas tree and came to a halt after a particularly vicious noise. Luckily it coasted enough and got parked out of harms way. Couple of phone calls later and it was flat-bed trailed home.

    When I got to the car, I plugged in VCDS and got the code below. This is the only time the DSG has thrown a fault code.

    1 Fault Found:
    8955 - Valve 3 in Transmission Part 1
    P17D4 00 [104] - Mechanical Malfunction
    Intermittent - Confirmed - Tested Since Memory Clear
    Freeze Frame:
    Fault Status: 00000001
    Fault Priority: 2
    Fault Frequency: 2
    Reset counter: 40
    Mileage: 155803 km
    Date: 2019.09.13
    Time: 15:26:57

    Engine speed: 771 /min
    Transmission input speed: 771 /min
    Transmission output speed: 3 /min
    Engine torque: -8 Nm
    Transmission fluid temperature: 88 ∞C
    Accelerator position: 0.0 %
    Clutch status: Beide Kupplungen offen

    I cleared the code to see if it would return immediately or not. Started the car and it pulled away and through all gears fine - no mechanical noises and the fault code did not come back. There were a few imperfect shifts but nothing horrendous.

    After a bit of research with my head in the SSPs, ELSA & ETKA I think I am looking at three courses of action:

    Opt 1 - swap out the entire mechatronic unit for a whopping £2500 parts bill
    Opt 2 - roll the dice on one of the rebuild specialists, but I'm not liking the high risk in that option - nor do I know the quality of parts
    Opt 3 - get the newer internal PCB/loom for around £300 and see if I can find a trusted source of OE (Borg Warner) solenoid for N435 & N440 thinking I may as well change the clutch valve on both shafts at same time. This option is not without risk but I have looked at ELSA info and have tackled worse.

    I also have a list from ETKA & ELSA of various pipes & O-rings which also need to be replaced if I pull the mech unit out. What I have not yet found is a trusted source of BW part numbers for all the various solenoid valves and I am not wanting to go shopping for clone/knockoff versions in China.

    I will keep looking of course, but if anyone has some good pointers it would be great.

    I've search for 8955 - Valve 3 in Transmission Part 1
    P17D4 00 [104] - Mechanical Malfunction

    As I don't have that listed. Have a read of Technical Service Bulletin Audi

    35 Gearbox malfunction message in cluster (DTCs P17D800, P179D00, P174000, P174C, P174B, P174F, P179C, P174A, P174E)

    Why do you think this is applicable to the OP's situation when not one of the DTCs listed in that TSB matches his?
