Just had my new to me 2013 180DSG 4motion (50k well looked after) remapped and very happy with the results. Low rev torque is way up and hills are now my friends. Only now on full throttle when the box changes up there is a very noticeable and worrying eeek noise every time the next gear up is engaged. It's hard to workout the noise as masked by the revving engine. Sounds a bit like a fan belt slipping or the kind of eeek a cold manual clutch can make when engaged a little too quickly. It happens when DSG harshly drops the clutch onto the next gear up and there is a spike of torque as the engine revs are forced down by the clutch to match the speed of new gear selected. Something doesn't like this new higher spike in torque and yelps in pain! There are no error codes on box, rear diff or engine. Data logged box and engine, nothing. Only happens when using new remap power at higher revs. The respected re-mapper has never come across this before. Ive searched web for hours. I don't want to remove remap as make the van so much better to drive normally but also don't want to do any damage on the rare times I need or want to max it. I'm sure it's wet clutches, can wet clutches make a noise when engaging quickly under very heavy load?? Can the DSG adapt to a more powerful / responsive engine to reduce load spikes during gear change? DMF stressed? A hose farting? Any ideas gratefully received.. Cheers Seb.

I'm in the SG1 Postcode area 20th / 21st if you want to pop up and we can have a drive and also log the DSG system?

Hey Martin that would be great, thank you so much. I'm actually going up north for a week and could either pop in on the 21st or I will be passing close to your workshop Monday or Tuesday next week if you will be there?

Seb.
