Took my car to vw for its service and they tell me I have this fault code 00665 turbo under boost coming up, they wanted to charge me £75 to investigate it but I thought I'd ask on here first to see if anyone else has had the problem and how much it cost to sort out.
Any help much appreciated.
Cheers

If you're prepared to investigate yourself, I would first check that your dv hasn't got a tear.

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 # 06H-145-710-D (or newer). RoW vehicles see: TPI 2016331 for details.
NAR vehicles see: TSB 01-07-70 or 2013392 for details.
When stored in conjunction with misfire codes and/or fuel trim faults see the notes associated with the following faults regarding PCV failure: Crankcase Breather Valve
If the Turbocharger is faulty due to mechanical / internal problems or the exhaust system is restricted (typically the Catalyst) this fault may be the end result.
When found in VW Golf/Jetta (1K): 2.0l CR-TDI (CBEA/CJAA): Verify the mechanical part of the Exhaust Valve Control Module (J883) is not siezed or binding.
