Injector Failures - Possible recall

Had mine replaced as well about 4 weeks ago. I always check my MPG on my morning trip to work, my record was 56 mpg, this week alone I've hit 60 mpg twice! :)

So whatever they are fitting, recon or not, they are better than the originals ever were. Perhaps if they are reconditioned ones as Crasher says then they have tweaked them in some way as part of that process. As far as being smoother is concerned, then yes it did feel smoother but that may just have been that the courtesy car was rough and being back in the Passat was better. So not sure on that one

Do you mean by doing your own calculations or do you mean just keeping a careful record of what the computer is showing?

Wasn't one chap complaining a few weeks ago that when his injectors were replaced he thought VW had changed the calibration on his computer such that it was falsely showing an improved mpg?

Quite sure he said that he'd checked the fuel consumption manually himself, but if others are seeing an improvement then perhaps he was wrong, particularly if Vince47 has been keeping proper records.

i have a 2007 a4 tdi 2.o 170 avanti, im quite new to this, or just thick !,i dont have any problems with my car, other than the cruise control stopped working on Saturday,but how do i know if it had a recall for the injectors, i have filled in an Audi owner registration form yesterday, maybe they will contact me if it is part of the faullty injectors.

60MPG ! - really in a mk5 170 TDI?? - I must be driving mine wrong - I have seen 53mpg MAX on the average readout (which is clearly an estimate based on all the discussions on this forum) and driving it like its on fumes. I cannot possibly imagine how it manages 60 - my wife has a Fiat 500 diesel and even IT is listed as 65MPG tops, and thats with a teeny little engine.

Just had my injector recall done yesterday, I must admit that I was considering taking it out today for a thrash to see if it was any quicker - perhaps I'm just the wrong type of person .. My inner voice says 'Mart, you could have had a GTI, so 45-50mpg (my av) is a very good figure lol..)

I think i want to swap my car for yours!

Mart.

Ring Vw UK 0800 333 666 ask if you're on the list.

My Passat 170tdi went into VW Heritige yesterday and had injectors and loom replaced foc. Well happy this issue had been making me think about selling the car rather than getting ripped for 2k plus for injectors :) Cheers VW.

Hi Folks,

Had my injectors and loom replaced on Monday and done nearly 500 miles since and can say that the on board figures seem to suggest that the car is indeed running more efficiently and returning a slightly higher mpg. I run down to Warwick from Birmingham using the M6, M42 and M40 and usually the car tells me I've done between 52 and 58 mpg depending on if I'm running late or not once I hit the M40! So far this week since Monday I've not had a reading below 58mpg and got up to 62mpg when I got to work this morning. The range calculator also seems to be suggesting I'll be getting more to this fill up - done a shade over 300 miles on the 1st third of a tank.

I can't say that it feels any smoother to drive but it certainly seems to pull away quicker and seems more eager to rev whilst putting out a lot less smoke from the back when I give it some boot.

All in all I can only say thanks VW as the car feels like new now especially with my new clutch and flywheel!

Had my injectors done yesterday on my 170 GT '07 plate. Car is erratic at low revs now surging every now and then , doesn't feel comfortable on cruise control and , get this , fuel consumption figures (displayed on the MFD, as opposed to real figures, I'm guessing) are ridiculous now . at some point yesterday it broke 80mpg! , just not right . My trip to work this morning which for the last 3 yrs has rendered between 39 -45 mpg depending on conditions showed 73 mpg - would be great if real. Phoned Verve and they said to bring it in and get it rechecked. One positive though, was at start up this morning where it was the smoothest start up for about 6 months . Maybe they've made a change to the ecu settings.

Sounds like the one I did when one of the new injectors failed immediately and I have heard of others doing this.
