Hi guys, I’m new to the forum but I believe I have experienced some of the same issues highlighted.
Quick story:
I bought a 16 plate Audi s3 (automatic) in January 2022 with 1 previous owner and 21,000 miles.
I had no issues until November time when I started to get the infamous “Gearbox malfunction, continue to drive message” and the usual issues that followed;
- Not going into odd gears
- Lagging
- Jolting when coming to a stop
At this point my car had 30,000 miles on the clock and I believed the error was due to an overdue oil change.
So in January 2023 I took it to my local Audi (Glasgow) and was advised that there was a recall for the hydraulic pump due to the potential of bolts becoming lose and wrecking the gearbox (apologies I’m not very technical).
I received a phone call the following day stating that they had completed the update which had been successful however the following error code appeared
P072C00 - Stuck in Gear 1
And I was advised by the service adviser that this did not fall under the recall and that Audi would need to do further investigation at a hefty price (£735 to be exact) to identify the issue however stated it would likely be a new gearbox required and they would not cover the cost.
Fast forward to today, I took my car to a DSG specialist in Glasgow (Caledonian Transmissions) and they completed a diagnostic check on the car and advised that there was error 2 codes appearing. The same one quoted by Audi and also
P0C2B00 - Auxiliary Transmission Fluid Pump Control Module - Feedback Signal.
I was informed by Caledonian that this is the error code which is caused by the loose bolts and they believed that the original error code quoted by Audi was caused by the 2nd Fault.
My plan is to phone Audi and advise them of my findings as I’m not happy that they are not covering this when it is clearly an issue with the Hydraulic/fluid pump which the recall was for.
If you guys have had a similar experience please feel free to reply or if you have any advice it would be greatly appreciated.
The offending manufacturing defect, auxiliary hydraulic fluid pump, sits deep inside the gearbox. The replacement process is very involved; lots of special tools needed and good technician skillset necessary. It is definitely a transmission out job and tear down... Mechatronic removed, dual clutch removed; the casing is separated and all internals are exposed.Presumably this pump sits within the gearbox or can it be accessed externally?
Thank you for clarifying. Much appreciated.see DSG image below for the red circled area. An electric motor is placed outside and drives the the auxiliary hydraulic fluid pump.
This electric motor is bolted to the outside of the clutch housing. It can be replaced without opening the Transmission. Unfortunately, not the case with the auxiliary hydraulic fluid pump...

Hello,My 34L4 related hydraulic pump replacement repair is taking unnecessarily long. It will hopefully be completed next week.
In talking to one of the service advisors, he said to bring the spare key for reprogramming; he thinks a DSG flash wipes out the key synch.
I know there is the concept of the holy VIN triangle of ABS, ECU and instrument cluster must all share a common VIN, but never heard of this gearbox-key relation. Anybody?
Yes, I had to take the spare key in to be reprogrammed, it wouldn't work after the new gearbox was fittedMy 34L4 related hydraulic pump replacement repair is taking unnecessarily long. It will hopefully be completed next week.

Just tried my key after reading this and it works perfectly. Only had the software updated and car tested, no faults found.Thanks. I wonder about the workings of this situation now; why would gearbox install cause keys to be reprogrammed? I knew about key programming need for Instrument cluster replacements, but so strange to hear the same for the gearbox change.
Also, in my case they are repairing the gearbox, not replacing it; it received the updated part/service kit and the associated software update/TCU flash. I'll still take my spare key with me when i go to collect the car.
Seem like you're not getting a direct answer. While my car is completely stock and i'm not really the intended person to answer your question, I've learned more than i wanted on the 34L4 by observing the the open guts of the transmission in the workshop and talking to techs and tracing part numbers and keeping track of control channel maps before and after the factory Campaign on the DSG.Has anyone who had their ECU and TCU mapped took their cars in for this recall?
What was the outcome?
I presume the TCU map would definitely be overwritten?
Quite a good read, although I feel like most of it went over my heard but gives a good guide on how the whole gearbox worksAlso, check this out for DQ381 basics and tuning (caution: it is lengthy!)

About fifteen years ago VAG and Ford (which included Volvo at the time) were producing specs to effectively encrypt/pair major ECUs in a vehicle to each other, partly as an anti-theft measure but also to prevent mapping. Engine ECU, Transmission, instrument cluster, ABS/(Body control) and Infotainment were all part of that strategy. I no longer work in automotive, but given that people still get their cars mapped, I assume it was never fully implemented or the chipping companies have continued to get memory maps from software engineers who were keen on making a fast buck.My 34L4 related hydraulic pump replacement repair is taking unnecessarily long. It will hopefully be completed next week.

Few questions, were you in warranty? did you buy direct from Audi? How did you go about the complaint.*UPDATE*
Well its been a long road but finally Audi UK admitted my gearbox implosion was exactly due to the recall issues! My box was sent to Germany and they have taken over 2 months to conclude this...I was told they have been checking all logs from my car to see if there was slightest modification as that would invalidate any reimbursement, its now been 2 weeks + and apparently they are just figuring out how they refund me!
As it turns out, i collected my car 12 hours prior to the recall being launched and despite me telling them for months that there was a major issue with these boxes, not one person bothered to listen and look into it ...
Yes. I had a new box fitted in Oct as a result of this recall, Audi covered the cost.
After discovering the issues I'll 100% be taking it as far as I can including the Motor Ombudsman. I've submitted a complaint to Audi UK.My 2017 stock standard S3 DSG had a gearbox malfunction error message. It’s covered just 14,500 miles from new in 2017. No contact from Audi about the ‘recall’. I took it to my Audi dealer to have it diagnosed. They came back with ‘there’s an error and you need a news gearbox’ and quoted over £11k. I’ve spent the last 3 weeks complaining to Audi UK. They eventually agreed to pay 50%, but 50% of £11k is still a huge amount to pay for a gearbox that should not have failed. I’ve lodged a complaint to the Motor Ombudsman (I know it’ll take ages to get a response!). Maybe a few more of those with the same issue could do the same ? Audi seem to have no interest in understanding the problem, or the scale of it, the dealer says the old gearbox will be scrapped. Any advice welcome. Thank you.
I talked to an independent this morning, they were very helpful, but after I gave them the Diagnostic code, they said it would need a new control box which would cost £3k + VAT and that excludes any additional work that might to be done eg clutches, bearings etc so I figured I’d go with the dealer and get a full new box with 2 year warranty. Neither option is very palatable.After discovering the issues I'll 100% be taking it as far as I can including the Motor Ombudsman. I've submitted a complaint to Audi UK.
My car is currently at an independent mechanic (automatic gearbox specialist) ... I don't know now whether I should take it directly to Audi instead?
Yep any cost is certainly not nice!!I talked to an independent this morning, they were very helpful, but after I gave them the Diagnostic code, they said it would need a new control box which would cost £3k + VAT and that excludes any additional work that might to be done eg clutches, bearings etc so I figured I’d go with the dealer and get a full new box with 2 year warranty.

Not sure, but for reference mine had done 50k, and the last 15k that i owned it I had zero gearbox issues i.e never once felt anything wrong with it, until randomly last week it felt like it was about to stall in the morning twice, then was fine for another 20 mins and then gearbox went completely.Just took mine in for the recall, hopefully nothing pops up. Does anyone know what the chance are of the issue actually happening? I've had mine since new and covered 72k miles and not had a single problem (as of yet).
Was it serviced regularly? I've been taking it to Audi with the oil services on the dot. Hopefully mine doesn't fail.Yep any cost is certainly not nice!!

I've just called Audi and got confirmation that my car does fall under the recall ... so sounding like the issue the recall was looking to prevent has happened to me.Can you detail the issue:
Stuck in gear?
Stuck in neutral / lost drive?
Physically exploded /cracked?
Warning to stop immediately?
This campaign / recall is for a specific fault with a specific build date range of gearboxes. If the fault with your gearbox is something other than the auxiliary pump failure then it’s probably not related to this campaign.
This is something that I have an issue with. Mapped or not this is actually a recall as opposed to an issue arising whilst in a warranty period. Bolts backing out on a cover within the gearbox is not something that is directly affected by mapping or upgrades. It is however a fault either by design or an issue that has occurred during the assembly process and should be honoured.Well too my car in for the recall and the engineers saw it was mapped so it wouldn’t fall under their warranty. The guy did say one thing which raised some eyebrows that the software update they put in the car increases the oil pressure and forces the pump to fail.
The other side of the argument is the gearbox wouldn’t have broke if you didn’t put the extra strain on it by tuning it.This is something that I have an issue with.
