I think it could be either or both with those codes. Are they using their experience or covering the possibilities and risk to them, by saying replace both? I don't know to be honest and would you believe their answer? To be fair I suppose they don't want to be held responsible for an ineffective repair - incorrectly diagnosed or partially diagnosed. 

 

Those faults are very recent, unless cleared before.  What if the mechatronic has only just become faulty and it is the cause for the misshifts.  Surely there is a chance the clutch packs will be OK? 

 

Dates and mileage should be first occurrence with the counter in freeze frame data increasing counter  each additional log (unless cleared).  

 

Matter of who you trust and if you could stomach the overall cost. I'd be a bit worried going in on basis of clutch pack replacement only on your head. What if it's not the problem -clutch packs fine,  or not the problem alone - as they've diagnosed both faulty. 

 

Thinking out loud,  would it make more sense to start with the mechatronic and try with the existing clutch? If the clutch is OK, great.  If not, you're only then back to doing both. The mechatronic can usually be removed / replaced in car, but access not easy, some peripheral disassembly.  Easier to do if the transmission was being removed on bench for clutch pack but the 2 together are pricey, as you've discovered.  

 

Mechatronics can either be repaired but not always successfully or exchange rebuilt or new unit put in.

 

Sorry, not totally clear in my head what you should do at this precise point in time. 

 

 

 

To be honest I don't know what to think. They knew from the start it gonna be both because I've told them that the clutch has been replaced. They gave me the price for the clutch plus an extra £150 for mec unit diagnosis so they knew from the start it can't be one. 

They're told me the clutch packs are damaged by the mec unit for not applying enough pressure when changing the gears and if i choose to replace just the clutch probably will going to end up in the same situation later and they won't guarantee for the clutch.

This make me think the previous owner was in the same situation choosing to replace just the clutch and get rid of the car after 5k miles

Also they stated that Skoda will charge £6k for this type of repair that makes me think again that they want to rip me off.

The fault codes has been cleared before so the dates are not accurate.

I was thinking to change the clutch because they removed the gearbox anyway drive it at home and try myself to remove mec unit and send it to someone to diagnose it again.

As they said that they tried to fix the mec unit but it's not repairable (witch I don't think).

Oh OK. So the transmission is already out of the car - at a specialist transmission repairers?

 

You're captive then!

 

I doubt they're in it to deliberately rip you off but are trying to stop themselves getting held responsible for an ineffective repair. 

 

Even if the codes have been cleared before that vcds extract,  it only started misbehaving April 23 right? It did 30k without these faults? 

 

I thought there would've have been some other signs of a failing mechatronic over the 30k miles of use.  

 

Not helping you a lot I'm afraid. If the transmissions out, then the extra £400 or whatever for a clutch pack and maybe dmf makes some sense if the clutch packs are worn, and you've got a chance it will be the fix or a major part of the fix.  If not, you just throwing money at a still faulty gearbox... 

 

Have they measured and inspected the clutch packs?

Yes the transmission is out now at them for repair that's why I accepted the repair because they told me it's just about the clutch from the start.
Yes you're right it did 30k without fault codes i have checked it after I have purchased the car. The fault codes came up just after entered into emergency mode.

Didn't had any sign everything perfect, smooth gear changes no issues at all.

I will check the fault codes again it right after I take the car from them.

They didn't gave me any technical information about the clutch ald level of wear just told me that's worn.

Update. So after they replaced the clutch nothing changed with the car so the same symptoms gear disengagement in 2-4-6 gears (especially when coasting) and lost of reverse gear until stop.
The reason why I accepted the clutch replacement was because I thought the car would be like before with no errors but it will wear the clutch in time due to mec unit being not able to keep it in gear.

The garage told me that the pressure on k2 clutch is too low and this will cause the gears slipping of.

I have attached the photos with the tests done by the garage.
The funny thing is I took myself the mec unit out and send it to ECU Testing and they couldn't find anything wrong with the unit. I just explained them the situation and what the garage told me and they accepted to retest it so I'm waiting for further news from them.

I'm in a very strange situation as I don't know what to believe. Maybe it was a mechanical problem inside the gearbox and the garage wanted to rip me off, maybe is something wrong with the mec unit so I'm totally confused.

This is most likely over my experience level now. I'll try to look at the charts later. But, with ecu and mechatronic testing, my belief it they may not always find the fault. If that makes you feel any better.  

 

Edit. As in they are usually worthwhile to try, but not always 100% in identifying fault and therefore rectifying.

I just finally found the problem. The mec unit was ok the problem was inside the gearbox with the output shaft speed sensor wheel G502 faulty. It was spinning around the shaft and I believe that the mec unit took wrong readings from the sensor and that's why slipped gears.

I believe the garage knew the problem as the results provided telling me that the mec unit has low pressure was fake but it was more time consuming and the fix a lot cheaper for them so that's why they told me the cost will be £3500+.I have managed to weld that sensor in place and now the gearbox is working again.

Wow. Good find. You think they knew all along?  And deliberately tried to deceive you? You're ruining my view of humanity!! Well done on the perseverance though.

 

Did you pull the box apart yourself or did you rely on the same fakers to do it. What a good outcome though. If I'm remembering back to the start of this problem one possibility was always the speed sensor, just shows how distracted things become and how even specialists do not check all the correct fault checklists before reaching conclusions..  so if they had of replaced mech it would of still had the same fault!

I think they knew as they tested the mec unit first and they found out the pressure to be fine. But the cost to repair the gearbox inside much cheaper than £3500 and that's why they tried with mec unit + clutch because is a lot of work and the price wouldn't be the same.

Trust me I come from a country (Romania) where everything was possible and why it can't be here in UK also where the people don't look at the bills when they pay for something and the majority don't have knowledge about it?

I just called the garage and explain them the situation and of course they denied everything I've told them and made me look like I'm crazy, telling me that the mec unit pressure could fluctuate in their tests.

Yes I pulled myself the gearbox apart and with the help of YouTube I have managed to fix it.

I have lost my trust in these fake mechanics and I wanted to be convinced that they acted right with me but it wasn't the case.

My belief is that they knew and when they've seen I ask questions(not an usual customer as they've had) they provided me that fake pressure tests.

Thanks for your time and your advice it really helped me to reflect at the entire situation I've been. Maybe will help someone in the future!
