Hi All

Starting this thread to keep track of Vento TDI related issues. The engine code is CLNA and is known as Polo sedan in some countries and VW Vento in India. I do have some specific questions here (CLNA engines are diesel gate fixed):

1. How important is it to clean the EGR and Intercooler?

My car is 6 years old - barely 20,000km on the ODO as I lived in Canada most of the time. I ran into injector issues immediately after dieselgate was fixed - it's better now. My concern:

1. I live in a country where Diesel comes with Sulphur and hence no DPF too. I cleaned the return pipe from EGR today and also the intake flap (aka Diesel throttle body). Was not able to clean the intercooler and EGR as it involved reaching the car underbody.

So final question is: How crucial is to clean the EGR and Intercooler in a country where quality of diesel is always a suspect? The EGR valve and return pipe was cleaned as I mentioned. I do have Vagcom no error in normal auto-scan.

Thanks in advance.
