Performance issue

[J6BXR]

Have a std 1.8t 150(arz) seems fine round about the town, sounds great ,drives great until you want to go over 3500 then its as flat as a witches T** and ideas? no weird noises from engine ,turbo etc .

cheers

[topher]

is it just flat or is it misfiring?

[J6BXR]

just flat like having no turbo.

Cheers

no engine light on i take it? probably won't be limp mode then unless someone has removed the engine management light (not unheard of)

jack the car up and stick your head under the drivers wing, find your intercooler and check neither of the hoses have popped off.. then follow the pipes back as far as you can and make sure its all connected tight.

check it on vag com too see if any fault codes pop up

could possibly be a MAF sensor, if it feels like the power is cutting out, or boggy! very common problem, and does not bring engine lights up!!

To be honnest how long have you had it? Mine used to drive like that before the remap, starts to pull then just flat after 3500-4000rpm.

Topher sounds like you are on the mark (again)

Jubilee clip on bottom intercooler pipe not there , no idea why some brown residue on the pipe corrosion of clip perhaps? , haven't tested car yet so fingers crossed.

cheers

residue means it's been blowing.. so thats probably the issue, opening up once the boost builds and p!ssing the air out. That would be the first one i've come across where the clip is actually missing though!
