Here a la frog i had to sign a disclaimer as i did not want the 'fix'!

I did here.

I spoke to my pal, the original owner, this afternoon. He got the letter about the fix and said he didn't want it done, and assumed it wasn't done, but now I wonder. I need to have a look.

Can anyone recommend a remap?.

Thanks for the info folks, very well received.

Alan.

Well, I did think there was a fault with the brakes, they would stick on for a second or two after taking my foot off the brake pedal, so I checked all the callipers, slides etc, they were all spot on. After doing all that I checked this informative forum only to find the elegance has hill assist on the brake pedal!. So, the brakes are fine, it rolls very free.

Hill Hold Control from the manual, it does not kick in on the level.

Something really is wrong with the mpg. I ran a 2.0L 110bhp for nearly five years. My normal mpg was in the 48-52mpg range, admittedly not in rush hour, but the run was only 5 miles each way to work so the engine never got hot. Post fix not a lot of change, but slightly higher revs needed to get same performance and regens did seem more frequent. 60+ on a run was the norm and not the exception. Near 40mpg towing a 1200kg low profile caravan was also possible.

At present I am achieving similar figures with a 1.5L 150bhp 250N/m torque petrol in an Audi A3.

My bet is the throttle valve venturi is completely clagged up from the K-rap being sent through it during EGR, also I bet the emissions fix has been carried out (and hence the frequent EGR and clagging up) despite the owners wishes. It's easy to check on line if the fix has been done.

 

My Yeti would not pull the skin off a rice pudding when I got it at 89K miles and was giving similar appalling MPG, after cleaning out the clag and allowing it to breath it was far more responsive and returned 45-55mpg overall. The shuddering and rattling on shutdown also ceased which I had feared was the DMF failing

 

I then had the engine remapped to allegedly 184hp, I reckon its the 170hp standard map, and the MPG has not reduced but it did see off the DMF.

I ran a can of 'on-car' DPF cleaner through the car today. 

 

Shared for info; I make no claims, make your own conclusions, these are just my seat of the pants findings;

 

The can is emptied into the o2 sensor, you let it soak for a while, the 5 mins at tickover, 5 mins at 2500rpm - then a decent test drive. It stopped smoking after about 5 miles. 

 

The instructions suggest the DPF is recalibrated.

 

Driving it? It feels like it's breathing a lot more easily, I can feel there is more torque when accelerating gently and it seems to coast further in gear 

 

I will certainly try this again, I feel there are more gains available but I'll use a different make next time as it wasn't much fun spraying the stuff into a DPF that was at operating temperature.

Hi Folks,

I've bought a can of DPF cleaner, well, the additive anyhow, I'll run that though by putting it into the tank.

I think the suggestion about cleaning the throttle valve may be worthwhile, however, speaking to my pal, the first owner, he said he has always been disappointed with the fuel consumption, I'm still wondering if the "fix", was done, and is responsible to an extent?.

Thanks,

Alan.

Did it also claim to turn the car into a f@nny magnet? 😆

Being a demi-god in that department myself, I didn't need to tick that option

🤣👍
