Over the years our Yeti 110 diesel has been coming up with the dreaded orange heating coil icon and have kept on clearing it down over the years. Stopped the Mrs from using Supermarket diesel fuel from Sainsburys and filled her car to the top with Shell V Power. Surprisingly since we have been using the Shell fuel the EGR light and onto limp mode has not come on over 8 months of daily driving to work and back. On holiday we could not find the more expensive fuel and filled up at Tesco's and coming home surprise surprise the little light came on and then limp mode.  Mrs turned off the ignition and waited a couple of minutes then turned on the ignition back on and manged to get back home ok.

Once home filled the tank right up with Shell and back to a clean running engine and no problems again?  Filling up with supermarket diesel fuel has convinced me there is a big difference and we manage 56mpg with Shell instead of 50mpg from the cheaper stuff. Have now knocked up 134,000 miles so it is a real effect.

I am now looking at the Skoda Karoq 1.5 TSI as another car.

So it would be the same on Shell regular diesel and it is the v-Power making the difference.

Regular Supermarket Filling Station or Shell, BP, Esso, Gulf, Texaco Diesel and the likes of Miller's Additive could do the same.

Hi e_Roottoot

 

Have not tried all the regular fuels you suggest but using Sainsburys, Tesco's, Morrisons and Asda we came up with the same problem over the years but filling up with BP and Shell top end fuels have definitely stopped the dreaded fault coming up on my VCDS reader.

We still have the old software installed and not had it updated by those nice VW people. Otherwise a lovely car and no breakdowns to date with just two new tie rods installed to stop the knocking over bumps.
