Question type: Maintenance & Repair

I have a Audi A4 2003 1.8t 5 speed manual car I
have drove my car after I change the oil 5W 40 and
now it won't start but was driving fine before I did
my oil change and this is my first time using 5W 40
my car starts but wouldn't turn over as if it's not

First off those 2 codes are to do with the turbo, second off when you have a code show especially in an audi you fix it not ignore it cause all your going to do is cost yourself more money. Your likely issue is the turbo has failed and now since you never stopped driving the car you likely fried the oxygen sensors and the cats as well as the Spark plugs due to irregular firing on a constant bases. Learn from this mistake if the engine light is lit fix the issue before you make it worse...

alot of people be angry at thier cars for not working when they need them but quite often its cause they don't pay attention to the warning signs

When I had took it to the shop a while back I asked about the trouble code and the catylac converter one of the technician told me it probably can be a sensor he didn't really think that my catylac converter the on my Turbo was going out can it be my 02 sensor that keeps my engine light on and causing all the codes to read

Can that be the reason why my car not starting now cause when I drive the car you can hear the turbo it sounds fine to me

the sensors in the turbo can sometimes do the same thing. Tho the oxygen and cat can get clogged if you use low quality gas. if the turbo is alright i would say try changing one of 2 things the n75 valve or the cat and oxygen sensor. I read a few forums boards and a few people said replacing the valve fixed the issue. The valve i would imagine would be not so expensive so i would start there. keep an eye on the turbo tho since these parts can go at any time.
