Title: REVO 1.8TFSI (CDHB) P0234, P0087 Post by: seppok on November 17, 2015, 09:22:06 AM Hello,
Seat Exeo 2011 1.8TFSI (CDHB) 160hp with REVO software. After flashing 2 years ago there has always been a P0234 overboost fault code. Funny thing is that after removing it reappears at idle. Now there is also a P0087 fuel pressure fault and limp mode... Any ideas?

It is mislabeled in many diagnostics tools.

Title: Re: REVO 1.8TFSI (CDHB) P0234, P0087 Post by: seppok on December 29, 2015, 03:34:25 AM Now the car was at the dealer and they flashed the original software. No fault codes, but now the engine runs for 10 seconds and stalls. They said the ECU must be replaced. This is hard to believe because the car could be driven before the flashing...
Any ideas? Title: Re: REVO 1.8TFSI (CDHB) P0234, P0087 Post by: adam- on December 29, 2015, 01:45:56 PM Revo modify the EEPROM too. You'll need a fresh EEPROM flashed as well, and the dealer won't have done that.
Title: Re: REVO 1.8TFSI (CDHB) P0234, P0087 Post by: seppok on January 29, 2016, 12:46:27 AM The car works now with a new high pressure fuel pump and the factory software. I have a strong feeling that the faulty software has requested too high fuel pressure and that broke the pump. I don't think the newer style pump with the roller cam follower could break when the car has been driven only 49k kilometers.
