P1888 - Coolant shut-off valve: Short circuit to B+

P1888 - Blocking Valve for Coolant (N82): Short to Plus

Possible Symptoms

  • Reduced heat output
  • Stalling, no-start, no communication to control module(s)

Possible Causes

  • Coolant shut-off valve (N82) faulty
  • Wiring or power supply to/from N82 faulty

Possible Solutions

  • Check Coolant shut-off valve (N82)
  • Check for applicable recalls or TPIs related to N82 failure resulting in coolant migration thorough the N82 solenoid connector resting in destroyed wiring harness(es)

Special Notes

  • Although VW does not have a TPI or recall related to N82 failure for this DTC, the following photo is from a 2013 RoW market (5G / Mk7 / MQB) Golf with CHHB 2.0T which destroyed wiring harness and resulted in a no-start:
