[cupra 200]

hi, just wondering if any could help as i got a probblem with boost pressure, basicely iv just started 2 notice that my bosst pressure changes after drive the car for a while,

when i start driving my car it boost at 10 - 12 psi (boost gauge needle steady) after about driving it 30 mins boost seem to drop to 4 -5 psi but boost gauge needle moves up down like it not holding boost very well, check all boost hoses clamp ect 2day all seem good, do u think my turbo is on it last legs ?

probably a fault with the penny valve on ure turbo have a look ware the actuator goes through the turbo have a shake at it and c if its loose in any way.

if your running a standard intercooler still, heat soak will be an issue in hot weather, and will affect performance and can cause limp mode. best check on vag com to see if you have any faults come up also.
