Dear All,

I got issue with my Audi Q7 in which 4 items has being replace accordingly but the GLOW Light still coming out.
This cause my Q7 (2014) cannot accelerate more than usual and pressing fuel paddle does not bring any changes when the GLOW light come out.

Action taken:
1) Change Fuel Pressure Sensor
2) Change Fuel Pressure Regulator
3) Change Fuel Pump
4) change Fuel Filter

But the above action does not bring any impact.

Dear All - Need your help. Please advise.

If you have not replaced your battery in the last year then that is the problem. The Q7 has all sorts of crazy stuff happen when the battery goes off. You need to have it recoded to the new battery otherwise it will not charge correctly.

Scan it and show the codes.... ours was and EGR valve that went bad. You r in Limp mode due to the type of fault code being thrown.

Did you check when the battery was last replaced? You'll need a VCDS to actually pull the codes. A ODB2 scan tool won't give you much information with a VAG group vehicle. Change the battery, it's about $250 and an hour of work to change it out. My 2015 TDI just had multiple glow plug and check engine lights. The battery (original, 3.5 years old) was degraded and needed replacement. That said, they did replace my high pressure fuel pump under the extended warranty at no cost to me. If you are the original owner and it's a 2014 and you've never changed the battery then that is the next thing you should do. There are many threads on this here.
