Try to use cataclean or diesel sistem cleaner, your oil need to be change on time becose that is affect your engine 

First is better if you come whit more details about your car, engine, year etc. If your egr problem is not bad try to avoid start stop option, short drive distance, use a  fuel sistem cleaner  for a few months. I don't believe egr delete plus remap is  a good options for long time especially if you want to sell car, or on Mot emissions test. 

First you need to run a diagnosis, after ceck air filter, oxigen senzori, injectors (return fuel). After that use a additive in fuel  to clean injector etc.(cataclean)  Ceck what drive mode you use, is a difference  between dinamic and comfort on fuel

Is a lot of labour  to change this egr cooler, is a lot of garage who will avoid to do this. 

Is for diesel engine?

That sensor is if you are lucky, in most case is egr cooler. Try to use a good dpf cleaner in your fuel tank, and avoid start stop option

@Laurentiu it's inevitable.

No amount of fuel additives or spray cleaners will get rid of the problem.

When the EGR cooler and valve have been replaced, you can however take measures to hopefully delay the inevitable......

 

I don't believe is OK to change egr cooler on premium brand on 60 k miles, and this is about 1000 £

OK tell me if you fix this after replace this sensor. What I see on Internet is egr cooler who is expensive to replace. To be onest  I'm disappointed to have this problem  from premium car on this mileage. 

Hello, I have a4 b9 2tdi 190 manual with 62k miles, and yesterday when I drive on motorway with 80 mph my engine light come on. I read ecu and error is P2002, and probably is egr cooler. Is anyone have this problem on this mileage, I expect this problem to come late on high mileage from audi. 

so on efficiency I have 53 mpg and on auto I have 56mpg 🙂

Hello, I read on audi book efficiency mod is for save fuel,but when I drive on auto mod on same distance I see mph fuel is increase by 3 mpg

How much you pay for remap and how much fuel economy you do? Is don't deserve 

45 mpg is for old engine from b8,mine is ultra and is around 52

2016 a4 b9 2tdi 190 manual

i expected from diesel to have better mpg in compare with petrol,im  a little disappointing about this engine mpg

Hello, I have a4b9 2tdi 190 manual and my average mpg is 45 with 31 mph average. on motorway with 70 mph I have about 50mpg. Is that normal  becose for me is look a little to low, or maybe my car  have some issues. 

hello, i have one key who don't work(i change battery,i try to sync with car,i see a few youtube video)is any option to order a new one, and if yes, from where? tnx

just i buy car today, i believe as well is not normal, car have 60k mile.is possible to be a mount or  flywheel

hello,just i buy a used a 4 .2tdi 190 manual ,and i have vibration when is park in neutral gear, and i feel some vibration when i keep  my hand on gear shift and i run on  road ,  guy from dealership tell me is normal because the engine and gear is longitudinal, is that true. tnx
