FAULTY AUDI A6 INJECTORS FITTED WHEN NEW ?

[markpain]

I have a 2006 Audi A6 3.0 TDi with 120,000 miles on the clock. I noticed that every now and then there was a lot of white smoke coming out of the car recently and my main dealer ran some diagnostics and found it to be a faulty injector over fuelling. However they have recommended that I have all six replaced at the same time which runs to over £4000 ! However Audi UK have said that they will contribute 70% towards the cost as the the car has a full main dealer history and I have owned it from you. Car manufacturers don't just hand out money for nothing so I presume they have come across this problem before. I saw on another posting that there was a faulty batch of injectors used in 2006 on this engine. Is this true? Does anyone know any more about this? If so I will push to get Audi to pay the whole bill.

I've just been informed I have the same problem with my A6 which has done 90k miles on a 55 plate. I have a dealer warranty through 2013 which I hope will cover mst of the costs but with a maximum claim of £2k it's going to cost me something. Apparently this is a common problem, the guy at the dealership guessed I had a 3.0 diesel A^ when I told him the problem.

I have another friend who had two injectors go on his A3 2.0 Diesel and Audi Uk paid for the lot. I would push for Audi UK to pay for everything, even over your claim limit.

Same here, 05 A6 3.0TDi, had all 6 replaced last year for £1200 (vs. cost of £2500) as a goodwill gesture though the audi dealer not Audi themselves, bloody things should've been recalled.

As a bonus, my MPG increased by around 7-10mpg after they were fitted.

And don't believe the £4000 price tag. the injectors are £400 each from Audi, and it's a 1.5-2hr labour cost.

£400 X 6 = £2400 + 1.5-2 hours labour.

Will this be the Siemens injector issue?

Here's the Technical Product Information for the fault. It is WELL KNOWN!

Audi TPI said:

TPI 2013969/12

Technical product information

Transaction No.: 2013969/12
White smoke or juddering at idle speed - V6 2.7 l / 3.0 l TDI

Release date: 11-Aug-2008

Customer statement / workshop findings

White smoke from the exhaust system and juddering when the engine runs at idle speed for some time - V6 TDI 2.7l / 3.0l TDI.

Technical background

Mechanical wear of the needle attachment of the injector leads to an increased fuel injection into the combustion chamber. The fuel is not completely burnt, which causes white smoke (unburnt fuel) or juddering when the engine runs at idle speed for some time.

This complaint occurs only on vehicles with more than 50,000 km.

Production change

Modified injectors from:

8E47A040360

4F37N026750

4EX7N004204

4L*7D049162

Measure

Try to reproduce the customer complaint so that it can be clearly assigned to this TPI. The following repair must only be carried out, if all the criteria (model/type, chassis number, engine/gearbox code, PR number(s), software version, code etc. ) match exactly. Otherwise this solution won't work and repeat repairs may be necessary. In such a case, we may reject the warranty claim and redebit the parts.

Read the measured value blocks 72 - 77.

3 values per measured value block appear there (for 300 bar, 600 bar, 1000 bar).

Should the values be higher than minus -45 ms (example - 60ms) or

on digit 2 be

higher than minus -15 ms (e.g. 20ms),

the needle attachment is worn and the injector is incorrect. To avoid repeat repairs, replace all 6 injectors.

>>>> Observe the algebraic sign (minus) in measured value block 72-77 !!!!! <<<<<
