Common Faults

  • Loss of power or limp mode, often with an underboost (P0299) or overboost (P0234) fault code
  • Blue or grey smoke from the exhaust
  • Whistling or siren noise that rises as the turbo spools up
  • Oil in the intercooler pipes or leaking from the turbo
  • Sticking vanes or wastegate, so boost comes in late, drops out or spikes
  • Shaft play or blade damage on the compressor wheel

Description

Summary: A component-level rebuild of the turbocharger already on your Vauxhall Signum 1.9 CDTi. You post your own unit in; it is stripped, measured, rebuilt, balanced and bench-tested in our Epsom workshop, then sent back ready to refit. Choose your year and power output above to see the price for your car.

  • Turbochargers fitted: 10 different part numbers across these years, made by Garrett

  • What this is: a repair service by post: your own turbocharger back, not an exchange unit
  • Warranty: lifetime, unlimited mileage

Finding Which One Your Car Has

You do not need the part number to order. Pick the year and power output that match your car and the price follows. If you are unsure of the power output, choose “Not sure”: the V5C logbook gives it in kilowatts at section P.2, and one kilowatt is about 1.34 bhp.

10 different turbochargers are catalogued for the Signum 1.9 CDTi between 2003 and 2006: they look alike from the outside, but they are not interchangeable. If you have the turbocharger off the car already, the label on the housing carries its part number, and the Affected Part Numbers tab lists each one by year, power output and engine code. If the label is missing or unreadable, send it in anyway: we identify every unit on the bench before any work starts.

Sending Your Signum Turbocharger In

  1. Choose your year and power output above, add the rebuild to your basket and check out.
  2. Complete the Repair Form. It gives you a repair reference and emails you a copy.
  3. Write that reference on a note inside the box, and on the outside of the box under our address.
  4. Plug or tape every port, pack the turbocharger so it cannot move, and post it to Unit 102 Reaver House, 12 East Street, Epsom, Surrey, KT17 1HX, United Kingdom.

On refitting, renew the oil feed and return lines rather than reusing them, and prime the oil feed before the engine first starts, so the new bearings are not run dry.
