Hey All,

 

New to Skoda Fabia's having just recently purchased a 2012 Fabia 1.2tsi with the 7sp dsg, alls been well with the nugget up until friday past where I pulled out my driveway got about 200 meters away from home then after a stop the thing seemed to have lost 3rd then scrambled to try find a gear before going into limp mode, flashing a spanner on the screen.
I did some research online and decided it may be wise to check the Mechatronics fluid levels and it was low, at 850mls , so I replaced the fluid for the full 1 liter, and the car seemed fine afterwards, up until this afternoon where the problem came back on the way back from work, again, only about 200 meters away from where I was, I was able to pull into a petrol station and switch the car off for a while and try again where it had no problems again getting home.

Now I have managed to use VCDS to get code's off the TCU ( luckily ) and I'm getting the following codes though they are not all that descriptive and I'm getting some mixed results on the codes interpretations:
p173c
p073a
p1862
p177f

p072b

These are all being listed as intermittent on the scanner.

 

when the car behaves it seems to drive perfectly with no slippage or shuddering

 

Ive seen some guys say that the accumulator can cause one of these faults, but they are usually accompanied with other faults it seems?? Anyone got any suggestions??

Welcome .

The Accumulator can cause faults. But you had a oil leak.  The oil went someplace.

There are 2 oils in the MCU and in the gearbox.

?

What oil did you put in? & where?

 

?

When was your car built.

The World wide recall on DQ200,s / Service Campaign in Australia was on ones 2009-summer 2012. '34F7'  Oil changed to mineral oil from synthetic and a software update.

 

there was a period 2012-2013 with No recall or service campaign. Maybe your cars age.

 

2013-2015 there was a service campaign. '34H5' for pressure / heat / leaks / cracks.  A software update.  

In Australia this Recall is on it's 3rd Recall Action / Service Campaign.  

?

Has your car had the 1st or 2nd recalls. Up to 2012, or from 2013? 

I drained and refilled the mechatronics unit itself, through the drain plug closest to the radiator, and refilled it though the fill hole under the starter motor, with the VW specific g004000m2 fluid, I'll have to call Skoda to see if it's been through any recalls, I've only had the car for 2 months

 

Otherwise the only info on the date of manufacture is 2012, not sure where to check what month

Oh I should probably mention that the bollom of the gearbox is a little wet so looks like the mechatronics pan seal might be leaking a tad, and is probably why it was low, but it's not actively dripping I'll be looking to get a new pan gasket, but want to make sure I get to the root of any other issues before throwing money at it if potentially I just need to replace the mechatronics

If it was just P173c, P073a and P072b then I'd suggest it's metallic crap on the gear selector fork position magnets.  Simple fix if you're willing to drain the gearbox and pull the mechatronics off as you just wipe the magnets clean.  The other 2 being present are more worrying as that points towards breakdown of the mechatronics TCU board in some way.  If it had the 34F7 recall done then the oil it previously had in it causes damage to the TCU board causing corrosion and short circuits.  If it's had a recall done properly then they should have put a sticker with the recall code written on it, in the spare wheel well next to the existing vehicle spec sticker.

I'll have a look for the label, though checking on the Skoda vin checker it shows it's had 1 recall for a look issue and that's it, I have yet to call Skoda and find out if mine is due for the other recall/service campaign, the other 2 codes you mentioned, could they be triggered by my dashboard cluster being taken out( led repairs) and the battery being run flat at one time?

I've cleared the codes and none of the codes have come back, however, the car still likes to jump out of 5th and free rev in auto from time to time, in manual it hasn't done this yet .

I might have to get the mechatronics clutch tool and check those selector forks,may as well replace the gaskets that are weeping while I'm in there 

The RECALL '34F7'  in Europe on cars 2009-2012 was not a RECALL as in a DVLA one, it was a voluntary and many cars never got it done. Started 2014.

The World Wide recall started 2012.

 

Then there is a period 2012-2013 when cars /DQ200,s according to Skoda / VW did not require the Synthetic oil changed to mineral and a software update.

 

2013-2015 is a Service Campaign in Europe. A software update.  Started in 2017 '34H5' 

 

WHITE LETTER UK,  a Service Campaign, started 2014 on cars 2009-2012.

Australia has these as RECALLS.  Repeated 3 times now as vehicles were missed. 

 

BLUE LETTER.  NZ and the 2nd Recall. back in 2012 with the first one all cars with a DQ200 DSG got a new MCU.   (No such letter / recall in Europe.)

This is about the 2nd issue, 2013-2015. (Now to 2016 in Australia on some DQ200 cars.)

Update this morning, after a week of the car not going into limp mode it finally did, so I have some codes again they are only

 

P073a- implausible signal

P137c-??

 

I'll have to search online to find out what p137a is, but it looks like that Philthegeek might be onto something
