you tried all the breather pipes mate? Who mapped it?

[rfn_hodgson]

breather pipes?- to do with the oil catch can ?? a tuning complex near me called top gear performance, i only went there because my mate has had his done there and no problems, the map it self wasn't a custom one as such it was like a bulk map if you know what i mean.

[Wazzzer]

yeah those pies, just to see if they are all ok etc.

It might be worth asking them if they could have a look. Just tell them it's happened since the remap

There's your problem dude get a proper map.. Who was it? Danny who mapped it? Mine has one of there maps and I can't wait to get it done somewhere else. But if that's not the issue try changing n75 valve that went on mine,

[Wazzzer]

I'm sure there is a problem with certain AUQ ECUs that needs sorting when you map them, Topher will probably know more

Boom, from R-Techs website

We have been updated with many emails from 1.8T 20v owners which have Golf, Seat & Skoda VRS with the AUM and AUQ engine codes. They have reported issues of there remaps from other tuners causing boost surge and 17705 limp mode / fault codes.

The fault IS based in the OEM mapping and once  remapped the fault is highlighted and becomes a really anoying issues when trying to drive the car in a smooth linear style.

[rfn_hodgson]

P1297 and p1560

Once again cheers for the help
