DQ381 MK3 Seat Leon FR 190

[iadam03]

Hello all!

I have a Seat leon mk3 190 DSG and I came across an emergency mode fault. Car only went into even gears.

Long story short, I have the car at a VAG specialist garage and they've come back to me that the mechatronics unit would need replacing. They've ordered the replacement unit from Germany. They said 2 weeks but wasn't too sure if this was the case. I understand that the unit will need programming.
Has anyone recently ordered a mechatronics unit from Germany and if so how long it took to arrive?

They did advise that the work would take 3-4 hours once it arrives.

Thank you

Was the fault code relating to that clutch 2 opens unintentionally?

Not a clue mate. The car was just going into even gears intermittently. I just had a call earlier that the unit would need replacing.

From experience, it's the control unit on the mechatronics module that needs replacing, that's a special order part tailored to your vehicle and takes 7-10 days to arrive.
However, the complete mechatronics modules can be fitted to any applicable vehicle. If they're not on backorder they usually arrive within a couple of days, there is a significant price difference between the two repair methods.

Thanks for explaining that mate. I'll wait the 7-10 days and hope it's sorted for end of next week

Thanks again!

Just an update on this.
The garage was able to source a part on Wednesday and the car is now complete.

The fault code they found on VCDS was 'P1735 position sensor'

Total cost was 2.5k. (Dealer covered this under warranty)

Thank you

Glad it all got sorted under warranty, that's a big old bill otherwise. How many miles was your car on when it failed?

 

[iadam03]

Hi mate. It was on 37900 miles.

I never use the paddles for what it's worth. My theory is driving the gearbox like a racing car is going to put greater stress on it. The motoring TVs and video have the click, click, click as if it's a F1 car. Probably my last words.

 

[iadam03]

I don't have paddles on my car mate. I only put the gearbox in S once it's up to temp (90 degrees oil temp)
Otherwise it's just sat in D.

I never drive my diesel in S but then you wouldn't . Gone are the old day of DSGs and no SCR when annoying people behind you, you could cover in diesel particles. Now jab your foot down, no smoke but they do go.

Apart from normal mechanical failure with second hand cars, you don't know what level of abuse the gearbox has been given... that's if it's second hand. Those people that chip their engines, the gear box is designed to take the torque matched to it, but not with with a chipped engine. May be yours isn't second hand but if so you don't know what the previous owner got up to with it and those videos of what you dont do with DSGs. The costs involved if they go wrong.
