Drove the A3 this afternoon and noticed that it wasn't boosting properly, part load is fine but go into WOT and there is a massive drop in performance.
Scanned the ECU and got the following fault code:
16683/P0299/000665 - Boost Pressure Regulation: Control Range Not Reached
Did a search on the internet for info and got this:
Possible Symptoms
Reduced Power Output
Limp Mode
Possible Causes
Hoses/Pipes incorrect connected, disconnected or leaking
Charger Pressure Control defective
Possible Solutions
Check Hoses/Pipes to/between Components
Check / Clean / Replace Charge Pressure Control
Special Notes
When found in 2.0l TFSI:
Check Boost Pressure Control Valve (N249), for cracked rubber diaphragm. A new/optimized Valve is available under Part # 06F-145-710-G (or newer), see TPI 2016331 for details.
I changed the recir valve 4 years ago when i remapped the car to the type ' B' level which was then the uprated item.
Looks like i will be doing the job again this weekend on the driveway, anyone had this same issue recently?
