Hi All, does anyone have any diagrams showing the exact whereabouts/position of the DPF on a 2.0TDi 170? Also has anybody had any issues with a DPF? Thanks

You'll have to let us know how you get on. My passenger door intermittently stays locked after opening.. possibly lack of use.

Chris Umpleby in Bradford, Indepenent VAG specialist.. very honest & reasonable

Yeah, not good. Very unlucky.

Exact same thing happened to me in July. My belt had disintegrated & fortunately fell in pieces onto the under tray. It cost me £70 at Chris Umpelby's VAG indy garage in Bradford for a new belt. Very Lucky.

I bought the bluetooth version plugged it in the back of the nav player & it currently flashes blue, is there anything that anybody knows of that needs to be done to make it work?

I have no idea which MMI version I have & I wonder if the version it is should make any difference.

Hi guys, thanks for getting my hopes up, briefly!!! I've just checked & I have no such extra plug in the top of my glove box.... devastated.... I do have a small blanking square which looks like it can removed to position the plug in the photos you very kindly uploaded. How can the systems be so different? Can anybody else explain why some have the plug & others don't? Is there something which can be added. I ha

My local VAG independent, Chris Umpleby fitted a new belt & confirmed no issues & no damage. Just an old belt that had split into slivers & failed due to being old...

Update, I've just inspected & found the V belt to have split in half & snapped. It looked to be in pretty bad shape. Its been squealing a bit recently & the AC was regassed two weeks prior & has been on most of the time putting more strain on an already old & 'past it' V belt. I'll get a new one fitted & report my findings back.

Hi, 2011 2.0 tdi 170, Has anybody suffered from a failed drive belt tensioner? First thing that happened to me was loss of power steering, then a minute later a warning came up saying the battery was not being charged & a battery symbol flashes on & off. I haven't checked the belt yet but it points to this being the problem. If anybody has managed to sort the problem please let me know what you did & if it can be done easily enough as DIY project.

I think its a build up of leaf debris not cleaned regular enough and once broken down clogs up any drainage holes. It does it in the boot area on either side & if not cleaned especially in the spring time builds up.

The only downside with the A6 is the costs when something goes wrong...

The only let down is the sound system... no dab & no way of connecting a phone to play music. Other than that I'm happy... they are one of the nicest looking saloons on the road... imo & the boot is ridiculously spacious..

I have had a 2011 C6 2.0tdi 170 le mans for 3 years now & its just passed 165k. Its due an oil & filter change but the exhaust tips are spotless, 100% cleaner than a petrol equivalent. Straight through all 3 MOT's. Advisory on the front discs on the last one which have been changed. No complaints from me...

I would say get it dried out & find somebody who can run a diagnostic scan.. probably followed by a chat with an auto electrian... Its not something that has happened to me, but its what I would do. Hopefully it will dry out along with any electrical gremlins.. Good Luck

Good to hear you got it fixed, its interesting how some garages try it on.. the problem I have is my AC blows frigid air intermittantly & I get the foisty whiff when switching back from AC to normal so that tells me its intermittant. It's not blowing warm air for sure just not the frigid air it should. I can only assume the gas is low & so a gas recharge is booked for Saturday morning, £42 through Groupon. I had it regassed a couple of years ago & no leaks were detected then. We're supposed to regas every 2 years so I can only guess it's due again. I'll post the results regardless.

Good informative topic/post this is, Easy question to answer.... has the facelift C6 got the same drainage issues under the windscreen scuttle/cowel cover thingy?

Have you had any joy fixing your AC?

From what I've read you can plug things into the pre face lift C6's but not the post 2008 C6's. We are stuck with bluetooth phone calls only and memory sticks for adding any extra music which is disapointing for a car of its age & spec that is spot on in all other areas. Well at least thats what I have in my 2011 C6.

I have an issue with my AC that might be connected. I had an issue in 2021 with the fan staying on all the time. I checked a few chat rooms & spoke to a customer who had an S5 with the same problem & the fix was to fit a new AC pressure sensor..£15, front bumper off, done.. fan not on any longer but still no AC... a quick £65 regas & it was sorted. Last week when the summer turned up, I obviously turned the temp down & the AC has been blowing very cold & then not so cold intermittently. In other peoples experience could it be low refridgerant & it needs a recharge? I hear they reuse the gas that they pull out including all the debris & moisture that have been taken out of all the cars that they do recharges on. Without plugging in & scanning for faults, has anybody had an experience similar & solved it?

There doesn't seem to be too much interest in here!!! Did you manage to sort your AC problem out?

Thanks for the info Steve, can the speakers be just changed for a more powerful alternative of the same size? I wasn't sure if it was the amp that determines the loudness & quality of sound. It looks like the 6.5 inch speakers in the doors will most likely make all the difference.

Hi All, I have the standard setup speakers in my 2011 C6, the sound is OK its clear & crisp but both the 2002 volvo S60 I had many moons ago & the 2006 Saab aero 2.8T I had previously where surprisingly better. Does anybody have any suggestions on how to add a little bit more mid range volume? Without breaking the bank where possible!!! Thanks,Graham

Its a code in your service book both front and rear have a separate code, its needs to be compred to the fitment section on Euro Parts for each disc & pads. They got mine correct first time without me needing to measure the discs & compare yhe pads.
