Difficult to say what the exact problem could be but something as simple as a failing battery can cause all kinds of fault codes on the car.
You need to get the fault codes read.
A cheap £5 bluetooth dongle and an app such as Carista will let you see and clear codes. Or if you have a look for somebody near you with VCDS they could read the fault codes .
There are plenty of very good VAG specialists that are cheaper than the dealer. where abouts are you in the country ?

I'm in East Midlands .(Leicester ) .
One of my friend got the vag com but don't think it's original one .so will do the the same or might cause other troubles ?

Hi .been to local mechanic .he checked the fault code and told me its a egr value .creating all kind of trouble .and told me its about 69% clogged up . He carbon cleaned the car and deleted the code and asked me to drive it in high rpm for a while .
Just thinking is there a way to clean it or my only option is to replace it ?
It's not showing engine light now .but other errors came back after a while and again in limp mode but gone again .

Hi me again . I ordered the new egr value and it's coming tomorrow .today I turned on the car and no engine light or other errors and it's not in limp mode any more but other issue .
Its starts fine but about after 20 secends strange vibration and turns off .it did that many times .then I started and kept the rev high for sometime till temeprater slightly goes up and it was fine .but when I was driving it did the same thing again few times .
Any idea if it's still related to egr ?
