Hi Guys,

 

Let me start, im a total noob here.

 

I just wanted to ask if its possible to swap an ECU with a another ECU that I can source and flash a tune file onto it and drive with it. They seem to void your warranty if you tune your car or do any physical modifications. Wanted to know if you swap ECU's and send it into the service centre, will they know that you swapped out the ECU? They obviously won't know that you had tuned the car but is it advisable to do this? The car has a long warranty and im already ready for more power, but I wouldn't dare touch the warranty due the infamous DQ200 and tensioner problems not he car. Any suggestions?

Suggest you consider a removable tuning box, DTUK or JB1 should do the job

If the 1.8 TSI engine and the DQ200 DSG concerns you because of possible fundamental design / manufacturing or material / software failings best not up the power. 

Or if you do just pay out yourself if they go wrong rather than trying to defraud a warranty provider.

 

Yes you can change the ECU if you want to. 

Can you source another ECU for your vehicle, and do you have someone to do the changes you want or need?

Thanks for the input, I am concerned with some design flaws but most are restricted to earlier generations, im pretty sure the newer ones have all the bases covered but I need to run them in to know they're solid so that when I tune the car there are no surprises. I know its a VW/Audi under the hood but I am cautious due to the brands dubious nature in our country (yes, they have a reputation to break here in India).

 

I have a professional tuner who is a friend who said it would be pragmatic to tune the car right from the showroom but im a bit too cautious. The defraud part is the other way around here, FYI :P You can read up many incidents online.

If you're intending to refit the original ECU for servicing or warranty work, the ECU mileage will differ from other modules in the car. Correcting this mileage might be detectable. It'll probably be obvious that the security bolts holding the ECU cage have been removed and replaced too. 

 

As you've posted your intent in a public forum, that might also be used against you if you were to make a warranty claim.

 

In short, yes they can probably tell if you've replaced the ECU unless you're very careful

 

 

The DQ200 DSG is sorted out, Skoda produce 2,200 a day.

Odd then that they are still having issues with some built in the past year that are now needing uprated Clutch Packs and Software Updates.

'Vorsprung Durch Technik' = Never risk voiding your warranty, it can cost you lots....

We had clutch packs replaced on our Fabia 1.2TSi due to judder at around 15k miles.

We have two leased Yeti 1.2TSi's. Both have clutch slip issues occasionally when cold one worse than the other. The dealer can't seem to replicate this so can't replace the clutches. As they are leased and go back this year they will be returned with the fault.

Our TDi Octavia with the DQ200 has so far been OK with 25k on the clock.

 

In contrast I've done nearly 250k miles in three different DQ250 DSG without a single issue.

 

There's no way would I significantly go over the DQ200's torque limit. And no way I would own a DQ200 out of warranty.

DQ200 standard can be fine with cars remapped to around 220ps / 320 Nm.

They certainly should not have issues at 192 ps /250 Nm like as used with the 1.8TSI 192 ps VW Polo GTI, 2015/16.

But then there are 48 various configurations of DQ200. To suit different engines and outputs, Petrol, diesel or hybrid 1.4 TSI / TFSI VW / Audi's.

I have the 1.8 TSI motor, any idea which one of the 48 variants goes onto it? Maybe I can find some more detailed info on it that way.

You have the one that should be left well alone and keep your warranty valid and if keeping it buy an extended warranty when the manufacturers expires.

Maybe if you need or want more power fit a Tuning Box.

Alright matey, ill leave it alone. Swapping the sway bar for one by APR to improve roll. Would you suggest the JB1 or Jb4?

JB1 is fine and easier to remove without trace, JB4 has to be wired into the ODB connector inside the car so is more hassle to remove.  The 4 can provide a bit more power and is more tunable but for most uses there is little in it unless you intend to track the car where you want ultimate power.

Firstly you can't just swap the ECU's ...unless you have a FAZIT connection due to component protection....& the Dealers have the FAZIT connection..

 

Secondly, ANY plug in module tuning box can be detected IF the Dealer & the FAZIT connection interrogate down enough...as the tuning box trick the ECU by asking for more than the actual values...so difference is certain stored values..
