[marc464]

hi i am getting what i think is really poor fuel consumption on my a3 tdi pd 130 i am only getting between 250 and 300 miles to a tank full had it on a scaner and there are no errors just wondering if any one has any advice on what could be the problem thanks marc

What kind of driving do you do?
I do 30 miles of M/way and about 5 of town daily and I get 500 out of my 1.9 tdi but on the m/way I sit behind a lorry and enjoy the music while I'm driving :-)

mines heavey on fuel aswell I had it scaned came up with fuel temp sender have not got round to swaping for a new one yet have you checked for a boost leak and are you getting a lot of smoke

[marc464]

hi power seems to be fine no excessive smoke had it on a scanner as well no errors found it is baffeling me really dont know what else it could be any help would be apriciated

have u changed the maf i might be on its way out this can efect MPG also check if you have any boost leaks and if you havent i would clean the EGR valve out and when was it last serviced some times a maf sensor wont show a fault code and are u doing mostly town driving

[marc464]

hi yea i have replaced the maf sensor but didnt make a differance dont think it has any boos leaks as preformance seems to be ok didnt think about egr valve but will try it yea town driving mostly bit did a run to santa pod and back wich is 300 mile round trip and i got 400 miles to a full tank still dont really thing that is that great for 1 of these engines but might be wrong ? thanks for the help people

hi mate i have just had my EGR cleaned at it was full of sluge and this was causeing the valve to stick i also had a vagcom scan done and i needed to repace a temp sensor and fuel temp sensor so will see if this makes a difrance but i recomend you clean the egr valve

[marc464]

yea if you could let me know if it makes a differance thanks marc

[anilkumar]

iv just had a new maf fitted becauses car was low on power il let u know what the MPG is like over the next week or so do you use supermarket fuel by since iv been useing shell mpg is a bit beter and iv put sum
FORTE ADVANCED DIESEL TREATMENT in since the EGR has been cleaned the car is much smother lower down in the rev range

[anilkumar]

hi just to let u know my MPG has improved having the EGR cleaned has diffrance to mpg and the way the car drives i need to change my fuel filter tho as its done over 10k miles another thing to check is tyre presers one of mine wrere down by 3-4 psi

[marc464]

thanks i will have to try that i am getting 34mpg at the moment which i think is really poor it was mostly town driving but was driving it steady has it made a big differance to your mpg i have also just replaced my fuel fillter and found a lot of black bits in the fuel so i removed the pump out of the tank and that was covered in a black like substance all over it so i also need to clean all that up

[anilkumar]

i was getting 32 mpg around town now getting about 39 and arond 45 on the motorway how many miles u got on yours mines done 96K and that EGR had never been cleaned and it was sticking and ful of crap black bits in the fuel i have nerver herd of this before :confused: have u tried driveing on the motorway at about 60 for about 10-15 mins and seen what the mpg is like then

[anilkumar]
