Hi all, I'm considering buying an A6 Avant probably around the 2005 - 2007 reg and hopefully the 2.7 TDI but probably fairly high miles around 100k. Are there any watch outs apart from the obvious like FSH?
 
As Avant search for rear washer pipe ... it run through interior can come apart at joins could fry bluetooth module, can also split at tailgate hinge and fry MMI rack components...

As 2.7 TDi... search for chain rattle ... injectors ... swirl motors flaps ...

Chain rattle fix £2k ish @ indi ... injectors £2k ... swirl motor flaps depending on what you get done another £1K...

As 2.7 TDi is de tuned 3.0 TDi include that in search on web as well...

Be prepared for extras after buying...

Other than that great cars...
 
Does any manufacturer make a diesel estate that isn't got cost you a fortune to maintain!? :crying:

In short the answer is probably no, especially if you are buying at the premium end of the market. These cars all cost £35k+ when they were new and unfortunately the cost of replacements parts is not affected by depreciation so major repairs will cost. Finding a good non-franchise brand specialist to do the maintenance will help to keep the labour charges in check but the cost of the parts especially if they are unique to the car will be harder to address.

Going back to your original question, the major issue with an early c6 avant is the rear washer. The hose is prone to splitting or simply coming apart at one of the connections, especially if used when it is frozen. In itself not a major issue except that it runs past critical electronics (the convenience module) under the front passenger seat and also past the MMI control unit, radio and navigation unit in the storage are on the passenger side of the boot. You need to first check the washer is working with reasonable pressure and then check whether there is any dampness in the front passenger footwell and any evidence of water in the boot storage area. In the case of the latter check not only for new water but also to see if there are any water marks suggesting a previous problem.
 
Honest answer mate if you going for an A6 the face lift or as close as 2009 you can go have better parts/software in modules newer, etc...

My own opinion early A6 ie 04 05 06 I would avoid unless very very good service history...

I will fish out date when they actually fixed the part which causes chain rattle...
 
To avoid chain rattle it looks like need a production date of newer than 01/12/06

The tensioners in question history...

These are P/N and supersession history

057 109 218 G DROPPED 01/10/2005
057 109 218 J DROPPED 01/12/2006
057 109 218 K CURRENT

With injectors... Tech.Service Bulletin suggests 06 onwards...

As I got a 3.0 Tdi with older one I was able to get history...

059 130 277 S
059 130 277 Q DROPPED 01/06/2005
059 130 277 AA DROPPED 01/06/2006
059 130 277 AB DROPPED 01/09/2006
059 130 277 AH DROPPED 01/04/2009
059 130 277 BD Current part since 09 (these apply to BMK BNG ASB engine codes)

So again 06 range better... 09 best...

Swirls flaps/motors on going thing but... Link:- Fontain Motors offer a improved arm linkage for IIRC £225 a side..

On ebay there are now remanufactured ones with improved linkage.. £340 for pair without motors...£225 for 1 side with motor...

Link 1: REINFORCED INTAKE MANIFOLDS 2.7 3.0 TDI 059129712 AUDI ALLROAD A4 A6 A7 A8 Q5 Q7 | eBay

Link 2: COMPLETE INLET MANIFOLD KIT 2.7 3.0 TDI 059129712 AUDI A4 A6 A8 Q5 Q7 VW TOUAREG | eBay

Again not saying these occur on all.. or all together... but forewarned... forearmed ;)

I have a pair of these eBay reconditioned/improved manifolds arriving in the next day or so (£375 for 2, with motors, plus £19 postage) in the hope I can more permanently fix the linkage issue, as I had my bank 1 linkage pop completely off one end last week. This is the second OEM one to cack out on me (bank 2 went while still under warranty with Fontain, but I now presume they only fixed the one instead of replacing both).

I'll keep everyone apprised of how I get on with them ;)
 
Some more info... as you can guess I've had a very turbulent year with mine as...

I have an Audi A6 Avant Quattro 3.0 TDi, 2005, 55 plate, engine code BMK, no DPF fitted from factory.

Production date of car from Audi customer care 07/03/2005, production date on sticker on the engine 25/02/2005 located on left area on engine between air intake on turbo and swirl motor.

A6, A8 - whining noises from rear axle (01R)

Customer statement / workshop findings

Whining noises in overrun with at 140-80 km/h after 30,000 - 60,000 km.
A6, A8 quattro with 01R final drive

Technical background

Wear of bearing and bearing carrier in the gearbox housing.

Production change

Change to new final drive (0AR / 08V), gradual introduction
(in MY 06-07 for individual engine-gearbox variants)

The 01R final drive has a black housing, the 0AR is unpainted (silver).

I've had chain rattle due early production car... there is also other meat to my story... but my advise... I feel 07/57 are the better ones out of pre facelift and then 09 onwards is when they really nail issues...

Again not saying all the issues I've posted occur but I wish I knew when got mine...

I paid £10k for car last year, did research before buying but not enough :(

I did most work at home ie service,brakes,etc I have paid out to the tune of £4400 in the year... the biggest costs was chain rattle fix £2.2K, C-Links/gearbox rear output seal £450, the rest of costs were decisions which I took to make car how I like or keep...

When I read a review before buying car highlighting high ownership costs I never knew it would be this high :shrug:

Yes, be very sure the MMI is all working correctly as mine is a nightmare & potentially very costly to sort. I have just posted this which explains:
I need some help as my MMI has failed due to water ingress (rear washer) in the rear n/s panel soaking the
Bose amplifier. (have upgraded music in my 2.7Tdi Avant S line 2007). I dried it out and it worked for a while but bit by bit the volume, radio, screen, blue tooth etc started to fail. Now nothing works. Have tried to find a replacement amp but to no avail, (£1000 for a new one +++?)
I understand there is a known problem and in certain cases Audi have admitted fault & repaired/replaced?
Has anyone out there had a similar experience? Any suggestions how I can approach this please .......
 
Well, not sure I want to be buying a car with potentially so much hassle and cost. Think I'll be going for a 2009 Mazda 6 Sport 2.2d, it's not an Audi but it's a lot of car for your money.

Good cars but not without their faults. 2.2diesel's stretch the timing chain, eat oil at an alarming rate, DPF fail regularly. And they are well known to self destruct engines by as little as 40,000 miles....get a petrol!
 
I assume the 2.0TDI (140) is more reliable?

Might be a bit of exaggeration their mate. The oil issue and DPF issue is nowhere near as prevalent in the 2.2d as it was the 2.0d and as for the engines self destructing can't say I have ever heard that and there are plenty of cars around with 100k on them.

Really? I did some research on these as i was considering one befrore i bought the A4.

Taken from Honest john. Mazda 6 2008 - Car Review | Honest John

2012: Timing chains of 2.2 diesels are stretching.5-2-2012: DPFs failing to regenerate can bring numerous other problems:
  • DPF Blockage (Loss Of Power, Warning Lights On Dash, Limp Mode)
  • Stuck In Regen Mode (Dumps Diesel In Oil + Reduces Oil Lubrication)
  • Blocks EGR valve (Carbon Backup)
  • Backpressure Destroys Turbo (Carbon Backup)
  • Carbon Backup Damages Injectors
  • Carbon Backup Damages Engine Seals & can cause overpressurising
17-7-2012: DPFs of 2.2 diesel continuing to fail, resulting in total engine failure if the oil/fuel level in the engine is not checked and addressed. Today had notification of another 2.2 diesel engine failure at 36,500, but at the time of failure the engine contained 8.5 litres of fuel/oil mixture so the driver had obviously not checked the oil level.



i own a mazda 3 2.2 diesel sport. i paid 21k for the car and its got 36500 miles. the car has been serviced at either mazda garages or citreon garages (using genuine mazda parts). last week the dpf light came. i drove straight to the garage, but about 0.5 miles before the garage, the oil light came on and the engine started rattling as i entered the garage. the garage drained 8.5l of deisel contaminated oil from the engine when it should of had 4.5l of oil. when restarted the engine failed. the car is now with mazda who are "considering" if it is a warranty claim. they have indicted 5k to replace the short engine. i have been told its a dpf regeneration problem can you give me any advice
 
Look i know there have been problems, what diesels don't nowadays? You've given one real life example and from what you are saying it's every car! If I have problems with one the likely hood is it will be a DPF issue and I have a simple fix for that, have it removed.

I agree... my car again is one out of many... some of the issues are production/mileage related....

At each time I've faced a big bill... I've test drove other cars and could not let go of my A6 :blush:

We have power of choice... so ultimately the chooser must choose...

At least due to the WWW we have more info to digest...

And forums can be more full of the owners posts with problems than the owners without...
 
Yes. go for an 09 TDIe. Much more reliable and cheap to maintain too.
A good one with low miles start at about £13k. Is that too much?
 
2.0 TDI Le Mans would do nicely!

Blasphemer! :) I still think they should have reserved the Le Mans moniker for the V6 versions... I realise they sell far more 2 litre vehicles, so it was all about prising a little more dosh out of the pockets of fleet buyers etc, but it just seemed wrong when they started slapping it on the smallest and least powerful engine offered for the model.

By the by (to contribute to the actual topic), I did get those ebay "remanufactured" manifolds fitted, and I firmly believe I won't be having to deal with the flap issue again... the catch with these was that they were a bit tight/sticky initially, so it would pay to lube them and work them around a bit by hand before fitting. I just gave the linkage sockets a squirt of lube, and had to reset the engine management light a couple of times (as linkages wouldn't travel to full extent initially), but was advised by my local independent (who did the fitting) to just drive as normal, and they would loosen up (which they have).
 
You say that, but at least they reserved the Le Mans moniker for the 170 version.
