Boost Pressure Too High - 335i

[soulfood]

Dear 335/Turbo sifus,Need Your Help/Advice.For The Past 2 Week, my 335 has been parked stationary with only driven 1 or 2days. After 2 weeks gone, i was starting to actively driving it until the engine warning light came up when i accelerated at 3000 rpm with a message " boost pressure too high, reduced power suspected".Did a diagnose and physical check on the engine and turbo area but nothing faulty detected on saturday. Retrieved the car with a view to monitor it for the next fewvdays. Today, driven a car climbing up genting and while climbing up the same warning message as above came up again when accerating it hard but after reset, the message gone. Appreciate anyone out there had faced the same fault and what supposed to be done.?Appreciate your feedback?

Bro hakim...tq for the note... Done that but could not find any...but thorough checking will be done if the warning comes up again...thanx again

Hope you resolve the matter soon SF.

Bro SF, try to check the actuator. My previous turbo ride has similar issue due to actuator.

What code is it throwing? It could be a the boost presure sensor.

Maybe u can list what mods u have, piggyback, dps etc, type of fuel 95/97.

Agreed with Hakim.

Chances are there is a leak, quite common for turbo charged cars. Its called boost creep. The culprit is usually the vacuum hose.
