Steve Q

You're welcome 🙂

Have you tried eBay including international sellers?

Could it be a damaged crank, or bearings etc? What does the mechanic think? Only way you'll know it dismantling the engine. But from the sounds of it, it could be a big bill.

I agree with cliff, most likely a seized motor.

If the car hasn't had the remap to map out the dpf or egr then this could be the problem. Have you had a diagnostic check to see if any fault codes flag up? Also the injectors can be sent off to be tested to see if any are faulty. Also have the injector seals been checked as a leaking injector seal can cause these symptoms.

Well the cheapest 2014 one on eBay is £4k. So at least that'll give you some idea. It will also depend on spec. You could push £3k in the hope to get £2-2.5k at a guess

What's the engine and gearbox? I ask as that often will decide what it's worth too.

Please keep us posted on how you get on. Feel free to list it on here under the fir sale section (this is free to do)

I think this needs Audi or an Audi specialist to rectify the key issue in my opinion. I think you'd have to sell it spares or repairs non runner.

Do t get me started. I need to replace the engine in mine but all this complexity has prevented me from doing it so far.

If it's anything like my 2002 A6 the imobiliser system has 3 components the instrument cluster, injection pump and ECU. Yours could be the same. To save yourself heartache I'd recommend you send your current cluster off to be repaired. Lok an eBay as there's companies that offer this service. You'll be looking at around £300+

You're welcome. Are you certain it's the ECU? I ask as the instrument cluster is part of the imobiliser system and failing clusters is not unheard of

Obd11, vcds, vagcom or Ross tech are all good.

Is it behind the lower dash on the driver's side or kick panels?

Welcome to the forum you'll find the members on here are a friendly and helpful bunch 🙂 looks lovely 👍

Id suspect a faulty switch or bad earth.

I can't say my A6 has this (2.5tdi). Are you sure there's no additional electrical equipment fitted? Or previously fitted? Do you know the cars history? It must have had additional bits added if it was a working vehicle. Signs of this would be holes drilled into bodywork or interior. Or unusual blanking covers that look out of place. Alternatively follow the wire to see where it goes. If it goes towards the engine bay could it be for electric fan?

How did you get on viewing the Q3?

Please keep us posted on how you get on

Further to Gareth's sound advice, if it's not the battery it could be a sensor or the rack itself.

You're welcome 🙂

I have to say the same, thank you so much Paul for sharing your knowledge and review. It's very rare we get this from new members. Keith I'm pleased the information has been useful, please keep us posted on how you get on searching for an A8. Cheers Steve

Let us know how the test drive goes. You might find the saloon slightly different. Not sure about that to be honest. What about an S4?
