0B5 Stronic Repaired by EcuTesting but still have a fault...advice please!

[Ga73]

Hi My 2010 year Audi A5 3.0 with the 0B5 stronic had a no communcation error so sent off to ECU testing for repair.

They've repaired the unit (apparently) but wont tell me what was repaired/replaced "due to their policy".

After refitting the mechatronic unit i still have the following code relating to the transmission (and therefore cant do any adaptions etc):

7965 - Signal Line for Gear Display on Selector Lever
P1893 00 [10101111] - Electrical Malfunction
MIL ON - Confirmed - Tested Since Memory Clear
Freeze Frame:
Fault Priority: 2
Fault Frequency: 4
Reset counter: 40
Mileage: 214388 km
Date: 2009.07.16
Time: 01:39:23

Engine speed: 0 /min
Transmission input speed: 0 /min
Transmission output speed: 0 /min
Engine torque: -44 Nm
ATF temperature: 23 C
Accelerator pedal position: 0.0 %
Clutch status: Beide Kupplungen offen

I dont really want to go to all the trouble of removing (and refitting) the mechatronic and sending back to ECU Testing if i can help it.

Does anyone have any ideas where i could start looking on how to resolve this... is this like at gear lever level or deep within the mechatronic...i'm happy to try any advice given, i know the very basics but not a mechanic/electrical expert by any means.

thanks all !

But the fault you have is related to the selector lever display not tcm. Check trims around selector lever and wiring. I laugh when I hear companies cant tell the customer what was repaired. It makes me think they don't have a fucking clue how to fix things.

This video shows in detail a few things and how to check them for similar fault but not the exact one you have but it will be in the same general area if you ask me:

Thanks for the link, spoken to ECU Testing "technical support" who suggested i check fluid levels, live/ground to the multiplug going into the gearbox and it's secured properly....

I thought ECU Testing were supposedly highly recommended? From my limited experience they either dont tell you what they've "fixed" or give absolutely no decent after sales support.

Does anyone else have any thoughts on what "could" be the issue with this P1893 error, VCDS reports this as "SIGNAL LINE FOR GEAR DISPLAY ON SELECTOR LEVER" malfunction.
The lights on the transmission lever are all dimly lit, when going through the gears it does register on the dash the correct gear but when moving into the +/- drive that doesn't register.

I'm desperate to get this resolved, if ANYONE has any more suggestions or pointers i'd really appreciate the guidance.... thanks all !

 

[Ziddywerks]

Did you check the selector lever and wiring for it as mentioned in the video?

 

[Ga73]

I've checked all the connections to the plug on the lever, earth good, live feed but I'm not great when it comes to the more "advanced" electrical tests to be honest.

Any help greatly appreciated though!

 

[Ziddywerks]

I would look up wiring diagrams and trace wire from lever to tcm. If wiring is good I would say tcm repair is shit.

 

[Ga73]

Thanks, I'm thinking the unit wasn't repaired correctly, didn't have this fault before sending to ecutesting... not impressed at all with their service.

They act like they're doing you a massive favour even answering the phone to you.

£550 pretty much wasted there

 

[Ziddywerks]

I would get you're money back in this case and also ask them to fix their fuck up if you ask me.

7965 - Signal Line for Gear Display on Selector Lever

All this slating ECU Testing off ?? Is it right ?


Nowhere in the thread have you Tested the "SIGNAL LINE FOR GEAR DISPLAY ON SELECTOR LEVER" Should it not be you that gets slated for being "half a job"

I would imagine being a signal line you would need a scope and specific knowledge to test it - Do you have both ?

This could be a Selector Lever issue - it is plain in the DTC - Why did you not send the selector lever for test and repair - You guessed and maybe got it wrong ?

Could be a broken wire ? You did not check that !!



PS. Go slate Ecu Testing as much as you like - They are nothing to me !!

 

[Dr Sheldon]

didn't have this fault before sending to ecutesting

Just saw that !!!!!!

My post #9 can be deleted / ignored

I wasn't "slating " ECU Testing exactly, I'm giving my opinion on the experience I've had with them.

For example the unit was delivered to them by dhl on a Friday morning, I called just to make sure it was received as their own tracking still said it was awaiting pick up... I was told "yeah were busy at the minute, if we have it then we'll let you know by close of business on Monday..." (their website says they keep you updated at every stage, obviously not the case).

I then had an email saying the unit could be repaired, I made the payment and within literally 2 hours I got an email saying it was despatched to dhl to me... that's good in one way but from my paying the cost to it being returned in 2 hours made me wonder exactly what had been done in that short space of time, I asked the question via email and was told "we don't tell customers what work has been done or parts replaced but everything is fixed" ... if you took your car to a garage and they wouldn't tell you what work they carried out would you be happy??

Then I get this NEW fault that wasn't there before and ask for advice, a member from the tech support rang me, made out he couldn't hear me and hung up sending a text to say I didn't answer his call... I rang back to be told by the lady who answered that he left a note saying check the live , earth and fluid levels.... Not exactly the"tech support" i hoped to receive.

I'm not a professional mechanic and have little experience with vehicle electrics, I was hoping that maybe someone might have had a similar issue here and could point me in the right direction or guide me, I didn't realise this was a forum where I would need to justify my experience with a company I've had dealing with

Ecu testing do a lot of advertising with good promises, would you rather I just pretend everything went perfectly or give you my real world experience???

 

[Ziddywerks]

If the fault is there now and it wasn't there prior I would say its related to the repair or lack or or possibly damage caused by them directly. It's hard to say and going to be hard to nail down without knowing what they touched and so on. Just my opinion. Also not telling your customers what you fixed is a shady business practice if you ask me. I fail to see how business can function and build trust with clientele without stating even the most basic of information.

I thought ECU Testing were supposedly highly recommended?

By whom? Certainly not by any of the UK professionals like @Crasher who frequent this place.

If only I'd known that two weeks ago

 

[Crasher]

I thought ECU Testing were supposedly highly recommended?

In the Notts/Derby area they are avoided by those in the know but there are always new victims to be found. BUT it may not be the mech, what is the VIN?

 

[Ga73]

@Crasher

thanks for getting back to me, the vin is WAUZZZ8F5AN014102

REALLY appreciate any help, advice or pointers you could give me

Thanks!

Morning @Crasher , just wondered if you had any further thoughts on anything I can try over the weekend to try to sort this issue.

Any help or advice is really gratefully appreciated!

Thanks Gary

The 0B5 box is simply a pile of stinking poo, if I was stupid enough to do this job (I am not) then I would start by replacing the wiring set with the revised version 0B5 398 009 F for £465.60 retail inc. but they are available aftermarket.

If I loved the car I would fit a new box at £11694 but UNDER NO CIRCUSTANCES would I gamble £4224 on a new mechatronic.

 

[Ga73]

Thanks @Crasher at the moment I'm trying to get ecutesting to let me know what exactly they did in the "repair" as doesn't look like the wiring/PCB was touched in any way from what I recall prior to refitting.

If I knew for certain this P1893 fault was due to the wiring I'd just bite the bullet and order an aftermarket board... love my car but I need this fault resolving

Hi All,

Just thought i'd post a small update here, after ALOT of emails/phone calls/frustration with ECU Testing they've agreed via e-mail to refund me less a testing fee which i'm okay with - still yet to receive the refund though !

So now back to square one kind of, with my A5 being a 2010 and very early 0b5 transmission (lucky me!) i'm going to purchase a revised PCB/wiring repair kit.

Looking online there are a few revisions, latest being revision 'F' as @Crasher kindly pointed out but this is JUST the PCB/wiring, i've noticed earlier ( D revision) also comes with solenoids, filters as well as the PCB/wiring.

Is it worthwhile going for the latest 'f' revision without the solenoids etc. or is the difference not that huge in me getting the 'd' revision which includes these ?

For the record car has done 130k just to add a bit of context.

Look forward to hearing your thoughts!

thanks,
Gary
