A6 Avant project

[Inside No A6]

Hi, having introduced myself in the new members forum, I will post here now.

So the A6 arrived on Tuesday, here are a few pictures.  It has error code P2149, which doesn't appear in the list of codes included with my OBDII tool, but I believe it is fuel injectors needing repaired/replaced. 

There is a warning on the dash for new brakes, and the EML is on, the dash also says 'service due'

 My son and I are hoping to repair this ourselves. 

 I've only had to pay for the recovery service so far.

So, can you fine folks point me in right direction to fix the error codes firstly? Any advice welcome. I am considering getting the Haynes manual online book, would that be recommended or not?  

Quite happy to purchase tools/parts to do all this.

Looks a good project. Could it be injector seals rather than the injectors? 

I'd recommend doing a full service. Check the brake pads, sometimes the wires and sensor that warns of worn brakes can in fact break.

Hi if I were you I would invest in a better scan tool if you are going to start doing injector coding, the cheaper scanners tend to throw up erroneous codes as bless them they don't have the capacity for in depth interrogation.

So the injectors would need to come out anyway, to check if it's just the seals, and as Stevey Y says below your post, would a better VAG scanner be a better investment?

Would a better scanning tool identify which particular injector needed attention? 

For example, it's a V6, so would a superior one identify which  of the 6 was cuffed?

 I realise now there may be a bit more involved than I first thought,  I didn't know that I needed to recode injectors when replaced, which needs specialist software?

What scanner would you recommend?

Hi yes VCDS or OBD Eleven will do the job, the OBD is the cheaper option and just as effective it should identify the rogue injector and allow you to code the new injector, if you don't code the injector it will run rough, the superior scanner will also allow you to re adapt sensors and batteries as well as release the parking brake should you wish to change the pads, [brake service position] it will tell you which speed sensor is playing about, the list is endless, I can recommend OBD ELEVEN PRO as it covers multiple VINS on every vehicle in the VAG range, is all you need is a reasonably new Android phone and away you go. Welcome to the world of modern cars!

Sorry Steve,  I must remember to read posts thoroughly before responding.

The OBD eleven pro looks good, I always worry about doing things through my phone though.

I think, (for no reason I can think of), the Ancel VD700 seems a better choice, but absolutely willing to be told differently, OBD eleven is also cheaper. 

 I had a look at the injectors, numbers 4,5 and 6 all look good, no wet patches on the parts below, the area below numbers 1,2 and 3 look as if they have been wet before, but dry now🤔, number 3 is wet with diesel though, I'm hoping that it's just one needing replaced( maybe spraying diesel about (I fear that I'm going to be told that's it's best to replace them all), can these be refurbished, at home? Would this be recommended or discouraged?

I'm dying to get stuck in. 

UPDATE:- I managed to get hold of a VAG OBDII tool, see pic, it won't enter 'engine mode', but will read codes, and I got a wee bit more info, it says same code,  P2149, but adds something about electrics, sorry, didn't note it down.  

 Update incoming..

My son had a look at both readers, and he prefers the OBD eleven, so he ordered it. Cheers

Hi you wont regret ordering the OBD eleven it has about the same capabilities as VCDS at third of the price, okay the tokens bit is a pain sometimes but in my opinion its interrogation capabilities are slightly better and coding is a lot simpler, your son sounds very tech savvy and will soon surround that system, always though the door to the forum is always open should you encounter any problems and I and the others will always try and put you on the right path to a solution.
