Turbo cut off

\015 Hi, I have a 2001 golf tdi mk4 90hp and im having turbo problems. When i am in the motorway and step on the gas with 4th or 5th gear the turbo shuts off and the car is horible to drive. When i restart the car then is ok again. What is going on?\015 Posted / edited by AnonymousUser on : 26-10-2020

Answers :

That's a (relatively) common problem with mk4 TDIs. Likely causes are the MAF (= Mass Air Flow) sensor in the air-intake (directly behind the air-filter) and/or the N75 Boost Pressure Controle Valve.
\015\012You should have your car's ECU read for faultcodes to troubleshoot the cause. It might also be useful to create several diagnostics logs with VAGCOM while test-driving.
\015\012This can be done by a mechanic using VAGCOM or by a VW dealer. See http://www.tdiclub.com/ (and it's forum) for more information and perhaps help.
