Chris

Thanks.

I will run with jojn 35's solution for the tome being

Let me know how you get on Johnaitken, hopefully your car gets sorted soon, think my problems are a bit deaper than that though now.

Car is still running rough, seems to be a coincidence that its after around 40 minutes of driving, the jolting and loss of power starts and EPC light comes on.

Its back in Audi again tomorrow, they have said they will look at it free of charge this time, I need to know whats wrong with it!


How did you get on Chris, any joy with Audi??

Thanks
John

John35,

Yesterday I went and sat in Tonbridge Audi until they had given HO enough details to enable them to asses whther they would give any goodwill, I was getting the hump with being messed around so I thought this was best course of action.

First of all they came back and said that as car is over 5 years they wont cover anything, I then pointed out that it is a 53 plate and only just over 4 years old! So they have offered 25% towards the cost of repairs, which is rubbish but as good as it gets. The total bill is £2700 so I will have to pick up £2025.

Basically you can follow Audi guidlines on servicing, maintenance and repair and should your car go wrong its your problem (-25% if your lucky).

Thats life I suppose...

Chrisbu,
What else had to be done other than the NOX sensor.

Which of the faults caused the problem or did they both ?

Chris how unlucky!! and can't even imagine how frustrated you are

My car was back in Audi today, they put it on the machine again and have said its now showing as the Fuel Pressure Regulator - being to low, which could be a number of things but recommended that I get the fuel pump replaced and the a new air filter, but also said they don't want to commit to it.

I think I am going to go ahead with replacing this but am really unsure as to whether it will fix the problem.

Its weird how our cars all seem to have the same problem but have been diagnosed with different things???

[JOHN35]

Things for my car have gone from bad to worse, the car stopped today completle loss of power gutted!!

I spoke to a very helpful guy at an Audi/VW scrap yard who said that it doesn't sound like it has anything to do with my fuel pump as I would have noticed a buzzing noise coming from the back of the car, which I haven't.

Would be great if Audi could pin point what problem was but seem to be getting could be this that or the other.

Anybody had same problems and outcomes please reply to this post.

Thanks

Hi,

I have the same problems. I have power loss in the lower rpm regions which comes to a stotter at about 2100-2300 rpm. At 3800 rpm and up it picks up and drives normal.

I have been in and out the Audi shop. for the past year. I replaced the following:

Sparks+Bobine
Nox sensor and Nox unit

Then they found out that the 2 valves where not functioning due to a broken tubler. They replaced the tubler, but there still was power loss. It has been chiptuned in the past so I am going to go back to the tuning shop and put it back in the original state. I have however little trust in the outcome.

Oh the dealers last suggestion to resolve the problem was a replacement engine...

It is fustrating

[JOHN35]

Hi Lexter,

I bet it has been very costly!!

After a very long think, I have decided to get shut of my Audi. I seem to be hearing/reading a lot of negative outcomes and yet to hear one person say that they have had this problem solved.

I am afraid of putting a lot of money into the car, and still not to sort the problem out.

Hope your car gets sorted for you.

John

Hi John,

It has been costly. I spend a lot of money (about 2500€) with little to no result. I switched Audi dealers, because the 1st dealership said "I hope we can fix it"... I replied "where should I go to if you guys can't fix it. They (the 1st dealer) stated (another guess) that it might be the petrol filter. Luckely this filter is located in the petroltank, so it would take a lot of effort (money) to clean it.

When I went to my 2nd dealership they, after replacing the noksensor because it was giving a message in the log..., finaly opened up the engine an quickly found out the tubler was missing, so 2 valves where not functioning. This took them almost a year! Then they stated there was a lot of dammage on the camshaft! NO KIDDING! I have been driving with a missing tumbler for almost a year. Then they adviced a replacement engine. Costs unknown.

I totally lost faith in the audi dealer. I am actualy looking for a different car. I don't think that these problems are normal for an Audi, but maybe a fist generation fsi engine is to much of a gamble.
