Hi folks,

 

Just wondered if anyone has had this issue. I have a 2015 Skoda Octavia mk3 1.6tdi greenline. About a month ago my EML came on and the code was for exhaust pressure sensor A (DPF), so my local VAG specialist replaced this and coded the car to inform it that it was replaced. 24 hours later same EML with the same problem, DPF. Took it back and he coded the car again with a different computer. No joy, EML back on same day. 
 

Booked in few days later for a deeper search and fount fault with injector 3 pushing to much fuel through. Replaced coded test drive all ok. 
 

Next day EML again with now saying glow plug 2 and DPF. Cat is clean air flow **** on DPF many times good flow all working as should. 
 

Any other ideas guys? 
 

car is nearly at 100,000 miles and serviced by Skoda went needed and only use Bp fuel. I am at my whits end and although the car has been brilliant for the 2/3 years I’ve owned it it’s now just a burden and losing hope. 

Find a “specialist “ that actually is and knows what they are doing instead of changing parts willy nilly, and no doubt charging you for the privilege.

Sounds like a fueling issue.  You might have to test each individual injector to see what the flow rate is.....also the common area behind that will be the High Pressure Fuel pump.  If you have high pressure at one end of the block and not on the other, you will get lumpy running and the car will run rich.  You might well have a downstream issue now with a blocked DPF and gummed up EGR valve - and the fault will seemingly be random until the upstream issue is diagnosed.

 

Big picture diagnosis - and as @Kenny R says - find a decent VAG specialist or use your local Skoda retailer.
