It might be the hoses on the inside of the engine bay deep in the sides connectiong to the intercoolers, hard to see and get to, def. sounds like a hose is off to me, happened to me a few times!

 

The car can go into limp mode without a CEL but you won't see 1.2 or 1.3 bar in limp mode.

 

also some tears in the hose are not visible until you pull it out and bend them to see the cracks.

 

Drove home, and noticed the car would not go past .6/.7 bar. I have to say if this is how it feels stock.....wow it is slow.
Anyway, I diconnected the battery for about 2 hours while I took the rear bumper off. The top hoses are secured into the intercooler and seem fine. I tried to check for any tears or rips and noticed none. Hopefully the car is now out of limp mode since I reset the ecu. I will find out soon when I go out and do some errands today.

 

Drove the car around, and it is back to normal today. Must have been some kind of limp mode, and is out since I disconnected the battery for a while. This is the first time this has happened to me, and was wondering if this may be some kind of recurring problem?

 

I have to admit I hate to keep repeating myself but I really think that these cars with any mods should include the upgraded silicone boost hoses, there is post after post of the OEM hoses failing, they are rubber and have poor connectors and handle much less pressure....costly but worth while, IMO
