4.0 TDI Turbo Module 2 Fault Code - Limp Mode
Guys, I had my actuator refurbished 2 months ago (complete with warrant) . It throwing up the following codes. Is it possible the codes are relating to another problem (listed in special notes of Ross Tech)? I hate the thought of having to replace the turbo (I did the drives side - it a killer of a job!).
18361 - Turbocharger Control Module 2 P1953 - 000 - Defective - MIL ON Freeze Frame: RPM: 0 /min Torque: 19.5 Nm Speed: 0.0 km/h Duty Cycle: 0.4 % Voltage: 11.86 V Duty Cycle: 94.5 % Mass Air / Rev.: 0.0 mg/str Absolute Pres.: 999.6 mbar 19805 - Control Circuit for Controller for Turbocharger 2 (J725) P3349 - 002 - Electrical Malfunction - Intermittent Freeze Frame: RPM: 0 /min Torque: 27.3 Nm Speed: 0.0 km/h Duty Cycle: 0.4 % Voltage: 11.78 V Duty Cycle: 94.5 % Mass Air / Rev.: 0.0 mg/str Absolute Pres.: 979.2 mbar |
Update: drove 20 mins this morning no faults or limp mode. Could someone advise where the earth connection would be for the turbo 2 actuator? I'm thinking it could just be a bad connection.

Hi did you use vcds to control the actuator to see if its working ok, there is a bulletin on here somewhere to service the actuator on the 4.0tdi.
these turbos are variable vain type so it could be sticky vains on the turbo do I google search on sticky vain turbos you do get diesel additives for this. cheers trev |
Sent unit back and it was repaired again without any extra cost. Appears to be fault free today - so far.
