2008 Golf Variant 1K Auto gearbox fault 18148

[joesurf]

Hi
my DSG 02E 6sp has fault code 18148 clutch temp monitoring. it will not clear.
Twice in the past month the shift indicator on the DPI started flashing and lost forward drive after reversing then going to drive away.
I looked into Clutch temperature, Trans oil temp and Mecha Control unit temp in advance measure blocks and am able to get a measurement of around in the high 90s.
There was about 10 to 15 degrees difference momentarily between the Control unit and the Clutch when i accelerated hard but would return back to be within 0 to 7 degrees of each other in a relatively short time. My test drive was in city and motorway including hills, driven as I normally would. During my test drive the gearbox operated like normal.

I was looking for VW NAR TSB 37-06-07 (2012681) but am unable to find it.
I registered in erWin and paid for a session and was unable to find it.
I also tried to search in the forums but couldn't
I am trying to determine if it is the Temp sensor that is the cause of the fault or the if the Clutch is overheating.

oops!

 

[NEtech]

Look in SSP 386.
N218 is used for cooling G309.
What are measurements MWB 019 and 064

 

[joesurf]

Bed time here. I'll be on it in the morning.
Thank you for your help.

 

[joesurf]

hello.
like i mentioned in my first post the temperature are all very similar
group 019, 83* 84* 83*

then in group 064, 80, 77

I have been looking around while I have time and have a couple questions.
I was looking for G309 and found it to be a footwell temperature sensor. Am I incorrect?
Or were you referring to G509?
And what am I measuring in Group 064 in the auto gearbox?
In the Advance Measure blocks there is no 064. I have looked twice.

 

[NEtech]

Sorry spelling mistake, G509

Please post Controller Channel Maps from DSG.

[Crasher]

The G509 is plugged into the Mechatronic and is combined with the G182 speed sensor, part number 02E 927 321 B although ETKA's fitment description is a bit odd but FI suggestion points to that number, easily available aftermarket from Febi and other companies

 

[NEtech]

G509 is 38.0 °C
Temperature excess 80 times.

hello
I sent the controller map very late last night and car was not up to temperature.
info I found before i got VCDS lead my to think G509 might be faulty.
I waited till VCDS was delivered to check if it was communicating and showing actual temperatures.
Since I saw that it was communicating it lead me to think it was something else i.e. Clutches or Mechatronic.
Original G509 in my country cost $250, Original Mechatronic cost $4,500.
There are "fleets" of VW in my country for sale listed as needing replacement gear boxes.

So I am asking the following,
Measured Value Block 064 is showing how many times G509 overheated?
If G509 was the cause of the permanent fault 18148, wouldnt it be showing wrong or no information?.
Are you suggesting G509 is the cause and should be replaced?
Or is it failure of N218 to cool G509?
Is there data to show N218 operation or failure?

Thank you for your efforts

part number 02E 927 321 B

G509 arrived and will install it now.
and post an update after

 

[Makke]

Did it work? I have the same faultcode, and i have changed the G509 and it shows temperature. And i cant get basic settings done correct because of the faultcode i think. Im thinking its a mechatronic issue?

 

[joesurf]

Hi. life got hectic and posting my result got put off. Thanks for push Makke!
Yes it did solve the gear box issues. My scan allways showed temperatures even with a dead G509. I did not do basic settings but it did take a bit of driving to sort itself out.
Gone is the hesitation on acceleration and way better fuel consumption. and no codes.
I wanted to confirm it was an open circuit beside throwing a code with the VDSC but that was not possible.
So I did a simple check with an ohm meter and verified it was an open circuit so i compared the new to old,
The first two are the speed sensor side. Quite different readings between the two ,I was surprised
The red cap is the new G509.The last two pictures show the proof I was Looking for.

I suspect you might have a broken wire between the G509 convector and the Mtronic unit if you replaced the sensor and still have a code.
But thats just my guess

I want to thank the others here for the help they had offered
Cheers
