Removing Remap (VW)

[dtr]

Thanks for that. It is now time to work out the cheapest option to get rid of the remap.

I could try the small garage - pretty much a scrapyard - in London (3hr travel) that apparently did the remap for the previous owner, but unless they have the original file I don't want them near the car again.

I could ask dealership. Failing that what are the recommendation for businesses around Worcestershire and Birmingham? Thanks.

This is underboost. Basically car is asking for a given amount of boost and it's not getting it.
This can be a boost leak but if the car has been tuned then it's usually a mapping issue.


Looking at it in this case it appears that from 1600rpm or so at full throttle the car requests 2570.4 mbar which is 1.5bar .

In Log03 at around 52s.

Specified 2570.4
Actual 1897.2

This is why you get limp mode for P0299.
start with stock software and see what happens

Phil at TRP developments should be able to do it. He is in Birmingham.

My tuner is based in Windsor and should be able to do it for £50 if not.

I looked at TRP and it appears they ceased operating around 2 months ago. So I would need some alternatives please. Windsor would be certainly doable. Thanks.

1800 mb is too low a pressure at high boost. I am still of the view there is a mechanical problem with the car that is not associated with the map.

May well be badly adjusted actuator but the tune should not be requested maximum readable from MAP sensor at 1600rpm.
Ergo the tune is st.
