Advice after I put petrol in my TDI by accident!!

You think you would never be so stupid as to do this. Obviously it's easy to do in a moment of absent mindedness. This is all driving up the insurance premiums for diesel owners. A $60 ounce of prevention can prevent it, so get a misfuelling device even if you think you'd never do it!

You'd think manufacturers could put them in by default.

From three decades in the engineering field, I prefer a pragmatic approach.

So, you should know that, if you leave just one damaged componnent in the chain of devices, you can render whole system useless again.

Anyhow, it's good to have your feedback and it's good that you fixed it yourself.

Start from the source and work down the chain - the components that are damaged not likely to get better by themselves, hence the process of elimination - cleaned the tank, sender, low pressure fuel pump, lines all up to the HPFP. If the injectors were or have been damaged I will find out in time. However all idling issues now resolved so unlikely but yet possible - I am not sure of the long term effect of petrol on piezo injectors. However the point I was making by the phased approach is that when the anticipated costs are enough to break out a sweat, it may be an option to put to customers.

I agree with comments about the misfuel device - this episode occurred after four years of owning the vehicle and when dark & tired. My first thoughts after 30kms of driving was a dirty batch of fuel. Only realised when I looked at the docket. Checked my insurance policy and they are quite specific about misfuelling and specifically petrol into a diesel which is on the list of exclusions.

Another recommendation for anyone else unfortunate enough to do this, is to take your vehicle to an accredited (Bosch) diesel injection specialist - they are doing most of the work for the dealers anyway - they also have facilities such as dynos which can be very useful when testing diesels under load. One of the questions I asked the dealer was if they had the facilities to test the HPFP which of course they don't have.
