Hello, long time lurker first time poster. Would like to run my situation by you guys and see if some light could be shed. Long story short, customers 13 S4 arrived from dealer with New ECU installed and a no start (I have more background info if needed but trying to keep it short). Found no comm with ECU, Diagnosis found t94 connector pins 67,68 for CAN bad/loose connection. Replaced both pins (2 pins on one wire from dealer). Comm with ECU has been restored. Tried to the best of my ability with long code helper to properly code ECU, still no start. DTC's set in ECU for park neutral switch input circuit ... Here's where I'm starting to get lost ... Attempt to perform basic setting on trans neutral position sensor IDE03545 but do not have correct security code to complete it. Go to TCU and attempt basic setting for trans range switch IDE00963 and will abort for safety reasons setting a DTC for 9725 Starter Interlock Signal P1724 00 [167] - Short to Ground.

I have access to alldata, wiring diagrams etc. Vehicle did start and run prior to ECU replacement. ECU was originally replaced because customer thought loss of comm was due to internal failure of ECU which was later proven incorrect. No modifications or repairs done to transmission, only repair made was above stated t94 pin 67,68. Any help would be greatly appreciated, auto-scan posted below :)

A bit of a shot in the dark, but please try the following for the ECM coding:

Hey Jef, thanks for the reply! I'll try and update the coding. Any thoughts on the ECU dtc P0850 park neutral switch input? I can see P,R,N,D in trans mvb while I move the gear selector, I'd assume that message is making across to ECU on CAN fine.

What I suspect (but unsure of) is the coding is making the ECM look for something that isn't there for it, hence the issue. IMHO, it is possible there no real issue with a P/N switch... just a confused ECM.

Gave the new coding a shot this morning and its giving me the "error 22: conditions not correct or request sequence error"

*edit - Jef, I agree with your hypothesis. Vehicle did start prior to new ECU, theres no way something got damaged while being towed between the dealership and our facility. Tried some other coding variations using long code helper and most get error 22'd.

*edit 2.0 - Dealership threw out original ECU, and is a bit unwilling to help. So its up to me and you guys! lol

Hmmm... I'm pretty sure the coding should work. If some one can double check my suggestion as a sanity check that would be nice. Also, if you ran an Auto-Scan at some point with the original ECM, that would have the coding. If there is a past Auto-Scan, section 3 here shows how to find it. If you have an old Auto-Scan, post it.

If you had the engine running when trying to code it, don't... key on, engine off. Be sure battery voltage is +12V.

Appreciate your reply's Jef, I gave it another shot this morning with same results. Battery was on a tender +12v, key on engine off, went right into 01-ECU and into 7-Coding, copy pasted your advised coding into the new field and got the same error 22 rejection. Wonder why it wont accept hmm.

Also we never saw the vehicle prior to this so we have no past scans unfortunately :/

First:
[Options]
[User Interface and Identification]
write numbers for wsc, importer, device no.
For example 12345 444 23456
[Save]
[Close VCDS]
Start VCDS

Use battery charger.
I would test: 0A250034052600060000

Followed NEtech's instructions and the coding took! no more incorrectly coded ecu dtc. I do still get a hard dtc of P0850 - park neutral saftey switch input circuit open or short to plus. Attempt to clear, dtc will set immediately.

So I believe the only remaining obstacle to getting this cranking is figuring out why that P0850 sets. I tried to go back into TCU and perform IDE00963 adaptation of trans range switch and basic setting will run for 20 seconds or so then abort for saftey, dtc for starter interlock will set, but this dtc will ONLY set when I attempt to perform IDE00963.
Attempt to perform basic setting in ECU IDE03545 - Adapt trans neutral position sensor and it still requires security access, that of which I do not have.

Any insight on the P0850? Again timeline goes ... vehicle starting, loss of comm with ecu, customer had dealer put new ecu in, dealer said still no start, customer had vehicle towed to me. I believe park/neutral sensor resides in mech unit. I doubt it was damaged from towing or at dealer. MVB in TCU shows P,R,N,D changes and cluster reports P,R,N,D changes as well. Attached below is an auto-scan from today after new coding was accepted.

Can be problem with P and/or N signal wire from aut.gearbox.
Check wiring and measvalue "Starter control Interlock or P/N status"
Could be this: ENG100919 Starter control: interlock switch

Looking at the factory wiring diagram for the transmission, 7-speed DSG transmission 0B5 (S tronic), wiring diagram #95. Go to page 7, on current track 79 is the F305, the Transmission Park Selector Switch. One side of the F305 is grounded, and oddly, the other side is wires to the J393.

46-08-042
field 1 = start/stop button
field 2 = Interlock switch/clutch switch (CAN signal)
field 3 = Gear Selector Lever (CAN signal)
field 4 = P/N or interlock switch P input (hardware signal)

What data do you get there? Does it change if you pull the gear selector out of P or N?

Any chance there is a wiring issue from the F305? Or a faulty F305 itself (which is part of the N110 shift lock solenoid)?

Hey guys, I did check "ENG100919 Starter control: interlock switch" and its just a string of 0's that don't change values when brake is pressed, attempt to start, gear selector in different positions.

Secondly I did take a look at the factory wiring diagram current track 79 and I do see what Jef is talking about there. F305 (as an assembly with N110) does get grounded and 1 wire leading to J393.
Taking a deeper look into the mvb 042 as you suggested I will detail out my results below (all initial values are with key on, foot off brake, gear selector in park)

Field 1 = 00 (when start/stop button pressed values change to) = 11
Field 2 = Not Installed (value does not change with anything I try)
Field 3 = 5.0 (as I move gear selector down values change to R = 6.0 N = 7.0 D = 9.0)
Field 4 = 11 (when in park, foot off brake) value changes to (foot on brake) = 01 (foot on brake gear selector in R) = 00 (gear selector in neutral) = 01 (gear selector in D) = 00

Some conclusions I can draw with the new info so far I believe is that maybe J393 needs to see "01" in field 4 to allow a start, which it does with foot on brake and in park or in neutral, so I think we're good there. Field 3 seems to be fine, values changing when gear selector changes position. Field 1 seems to be fine as well.

Field 2 value of "not installed" I think is our issue. Coding for J393 and TCU appears ok and correct. Only dtc is for a luggage compartment light set in J393. Everything I can see so far it appears that any change in gear selector is conveyed correctly.

I will take apart the center console to inspect F305 and N110 in the mean time. I do want to say you guys have been such a big help, sincerely thank you.

*Edit - Managed to get some time for more testing today and wanted to update. Found pin 25 (gy) of 46-comfort putting out .13V with key on, found .13V at pin 3 of F305. Wire resistance = 1.6 ohm. Also found an increase in voltage to 1.10v when brake is applied, gear selector position doesn't effect voltage. Also found 0V at all times on pin 4 (ground). I'd think I'd see voltage on pin 4 (ground) at some point right? .13 and 1.10 volts seem like an arbitrary number too? Connectors and wiring appear ok.

field 2 = Interlock switch/clutch switch (CAN signal)
This may be for cool 3 pedal car people, not you 2 pedal car types. :) So not installed may be normal.

field 4 = P/N or interlock switch P input (hardware signal)
I suspect your values are good. There are two bits there.... XY. X looks to be the interlock, 1 being you can't pull the gear selector out of park. When you step on the brake pedal, the N110 fires up, pulls the pin back, value changes to 0. Y is "P input" as in Park (and neutral), so a value of 1, put it into gear and it goes to 0.

So field 4 reading 01 should be good IMHO. To that end, if that is good... WTF is the ECM's issue? :confused:

Ahh I do see what you mean. I'm thinking the same thing, what the hell is that things issue lol


Any other areas/data points/connectors/wiring to check from any of you fine gentlemen would be appreciated, at this point I'm more or less at a loss.

So Access Start and CCM are the same box. I would expect them to report the same/similar data...

05-08-005
field 1 = Brake light switch (Term 54)
field 2 = P/N or interlock switch P input (hardware signal)
field 3 = P input (hardware signal)
field 4 = this space for rent

What shows up there?

Hey guys, this morning got a second to see what the 05 start auth module reports. I'll detail the findings below ...

*All initial values are with gear selector in park and foot OFF brake*
05-08-005
Field 1 = 0 - brake applied value changes to 1
Field 2 = 1 - brake applied and gear selector shifted to R = 0 - into neutral = 1 - D = 0
Field 3 = 1 - brake applied = 0 - once shifted to R, N, D value stays at 0 even with brake on/off

It appears every action I take with gear selector or brake application is conveyed correctly in the 05 start auth module as well. I'd assume it wants to see field 1 = 1 field 2 = 1 field 3 = 0 to authorize a start and that is what I'm seeing in mvb.

Any thoughts on this data confirming I do not have a physical issue with park/neutral switch? I'd be happy to test wiring/voltages to/from start auth or ecu I just don't know exactly where, or what values I'd be looking for.


*Edit* - Was looking through the EWD for starting system and remembered I did go through and check starter relay's 1/2. Terminals 86 of both relays have 12v from fuse 16 40amp. 12v at terminal 30 of relay 2, continuity between terminal 87 of relay 2 and terminal 30 of relay 1. Continuity between terminal 87 of relay 1 and starter solenoid connector. Just some more info I thought pertinent to the situation. Starter relay side of things looking ok.

Under the ECM Basic Settings, I see this option:

IDE03545 -Adaptation of transmission neutral position sensor

I've never noticed this before on any car... ran this by Dana and we both are of the opinion "worth a shot, but don't know what to expect". To that end, proceeded at your own risk.

Our drunken guess is that when a dealer installs an ECM, part of the factory scan tool test plan would be to do this step... and maybe it wasn't done on your car for reasons unknown.

Hey Jef, I did see that under ECM and have attempted that but VCDS wants security access, that of which I do not have :( . I tried security access numbers 27971 and 79153 and still no go. I got those 2 numbers from THIS link.

.... well f##k. :banghead:
Coming up with Security Access codes is not my thing. I'm hoping some one can fill in the missing blank here.
