Good Morning All,
I have been having an intermittent limp mode problem with my Lupo 3L. Sometimes it will struggle to reach 120kmh on the autobahn. if i turn it off and on again it normally fixes it. I scanned it with VCDS and got codes 17964 P1556 - Charge pressure control - Negative deviation. I belive this is called the N75 valve. I ordered one on ebay that i hope is compatible . It stated part number 1H0906627A which i think is correct.
When i fitted it yesterday it made the car a lot worse, it wouldnt even get upto 80kmh. I realised there are two very similar looking devices in the engine bay. Please see attached image. I changed the one on the right. Can someone identify what each one does so i know if i changed the right one. Also, when i fit the new N75 does it require any programming or basic setting?
Cheers
Kieran
