Restore crisp boost response on your turbocharged VW or Audi with the Boigevis circuit breaker valve 06H145710D—the correct OE-reference turbo diverter / bypass valve for EA113 and early EA888 1.8T / 2.0 TFSI / TSI engines. Direct-fit for Golf GTI MK5/MK6, Jetta, Passat, CC, Tiguan, Eos, Beetle, plus Audi A3 8P, A4 B8, TT 8J and more.
Older diaphragm-type valves tear, leak, and trigger P0299 / P0033 boost faults, sluggish throttle, and turbo compressor surge. Boigevis supplies the upgraded piston-style revision: precision-machined body, stable spring calibration, and a leak-free seal that holds boost on stock and Stage 2+ tuned cars while safely recirculating pressure on lift-off.
Built to OEM dimensions, batch-tested, packed under the Boigevis label, and backed by a 1-year warranty with Guangzhou warehouse stock and 24-hour dispatch. A smart, affordable fix for workshops and enthusiasts who want OEM-grade VAG turbo behavior without the dealer price.
Choose Boigevis 06H145710D—seal boost, kill lag, drive sharp.
