Possums, heaps of 'em.

Razza123 - I'm sure if you have your passat fixed with the updated injectors you'll love it for many years to come - especially if you take it up the oxley highway now and then

Yes thank you . Only a short time driver of the Passat but I am impressed with it. VW Aus tell me there is a replacement policy for the injectors depending on VIN number of the vehicle and a fuel test to make sure no E10 Diesel was used . Interesting point for owners and future buyers --- using E19 diesel fuel voids warranties. I dont use this type of fuel anyway but its a warning for anyone who might be tempted to use the cheaper fuel . VW tell me they insist the dealer does a fuel test from the tank in the vehicle and must confirm to VW Aus that no E10 is present.
I think this would apply to many of the VW diesel range ????

The dealer has not yet looked at the vehicle which is a little disappointing.

And yes the Oxley highway is a drivers road . The long run up the mountains tests any car and you are rewarded when you get to the long straights further on. I counted over 70 corners of 55 kms per hour or less ( most are 35 km ) and many of these can test just how far the front wheel drive tramps sideways on the rougher ones. Much more pronounced than rear wheel drive. I get through there as easily in the Passat as with previously owned benz or bmw models as long as one is aware the front wheels will tend to sometimes skip sideways just to keep one ones interest. I think the vw diesel tends to respond with power quicker with very little turbo lag but also gulps fuel quicker too. Its about 0.7 litres per 100 kms more fuel used than my previous benz for that run. Not suggesting unsafe driving though at all. Oh the woes of work travel lol.

I thought Exx signified petrol with xx% ethanol added and it was Bxx that was normal diesel with xx% biodiesel added.

Mine has been at the dealer two weeks now... I've forgotten what she looks like

Yes you may be correct Kaanage . I did mean diesel with the bio additive which is the Bxx% and not E as I mentioned . Thanks for the correction.

Two weeks wait --Heck I need my car back asp . Heaps of work running to do before xmas .

Yeah it was probably my own fault. I told the dealer to take all the time they needed as I have another car. But I am growing rather tired of driving around in the 1970's...

The injectors , loom and timing belt have been repaired by the dealer at VW Aus expense. Havent seen the invoice yet but I have been assured by the dealer the updated injectors were used.

Interesting point: the dealer showed me a sample of diesel fuel from the cars tank and it was virtually black with what looked like floating muck while a similar sample of good fuel was clean. They drained the tank and replaced with clean fuel. I had used four or five tanks of so called fuel from Aussie's largest shopping chain local outlet. They tested for Bio additives as requested by VW but found none. It appears a large percentage of the cars with injector problems locally also had dirty fuel.

As I mentioned before I have friends who had numerous diesel injector problems in mercedes cars and vans using cheap fuel but previously ( for over 5 years) I always used fuel from the red and yellow retail store outlets and never had a problem. Only recently I swapped to the other large W one. Bad fuel may not be the main cause of injector failure but perhaps its a factor.

One more thing: Thanks to this forum for the info on the injectors and failure rate. It was a huge help to have everyones input when talking to VW Aus and the dealer.

Glad to hear you've got your car back! Mine is STILL at the dealer. It has now been three weeks...

Interesting info, and I have to admit I'm amazed VW footed the bill if you had contaminated fuel. Makes me think there really is a quiet recall going on, but Lindsay suggests otherwise.....

I have never considered anything but BP or Caltex Vortex, and have driven 40kms on empty ( 0 range left ) past Woolies and other servos out west to get to one of the above. I'd walk before I'd put that stuff through my car, you get what you pay for. Even draining the tank that low and getting into the sediment scares me less. A bug in a diesel tank is a nightmare.
