Welcome Reg, and thanks for joining. To save you buying components in the hope the fault lies with them, have you tried measuring the voltage ( and earth continuity) at suspected components? That would be my plan of action - if it helps. Regards, Gareth.

What is the ID of the pipe Richard? Regards, Gareth.

I've still not given up on the A6 and still considering options. As the title suggests I'm wondering if the Audi/VW 2.5tdi inline 5 engine could fit in my A6 C5. Here's the research I've done so far: Pros 1. I'm thinking parts would be more readily available for the 5 cylinder as it had a 17 year production run 89-06) in various cars including the A6, VW T4, VW lt and Volvo 850/V70 (known as D5252T). Whereas the V6 only had an 8 year production run in Audi A4, A6, VW Passat and Skoda superb. 2. They are an older style of engine so easier to work on and they can be converted to mechanical fuel pump rather than electrical. 3. In the A6 and VW LT they are mounted longitudinally and can mount to the 01e gearbox that's currently in my A6 as bellhousings are the same. 4. No change in emissions class as the 2.5tdi 5 cylinder is euro 3 like the 2.5tdi V6. 5. Proven to be a very reliable engine and can run on veg oil (WVO). Cons: 1. Longer engine so might be a tight squeeze in the engine bay. C4 from bellhouse to front of viscouse fan measures around 64 cm, while the allroad seems to measure around 58. The small difference looks to be a result of the fan wich is pulled forward on the allroad. 2. Less refined as the V6 with max power output of 140bhp whereas my A6 had 155. 3. Can't use a code reader. I5 engine uses an archaic 8 Bit ECU with no VNT provision, but can be converted to run the later T4 multivan ECU which can be flashed trough OBD and is capable to run a VNT turbo. Unknowns: 1. Does DVLA need to be notified of the engine swap (other than engine code) as I'm going from a 2.5tdi to a 2.5tdi? (I know insurance would). 2. Getting the C5 instrument cluster to work (but this would be an issue with any engine swap) 3. Would engine height be an issue? 4. The C4 engine mounts seems not to be attached to the subframe but directly to the cars body, so I doubt if that can be done without welding. I'd appreciate your thoughts on this 🙂

Apologies I've only just seen this. I still have the A6 but no further forward to be honest. They definitely become a labour of love. The issue I've found with the 2.5tdi V6 is parts availablity for the engine now. How are you getting on with yours?

Ideally you'll need a diagnostic check to see if any fault codes flag up. It might also be worth contacting Audi to see if there's a software update available for the mmi.

I guess you could always get a diagnostic check at a garage? Or an automatic electrician

Hey all Have an annoying issue , my mmi sound stops working from time to time , i have to turn off car and unplug the leads from the amplifier in the boot for around 10 min and then reconnect and it works again . Has anybody else has this issue , is there a better way to fix this without having to unplug everything ? turning mmi off and on doesn't work . Thanks

Will try that again with new keyboard😁 Brother has all the diagnostic kit getting him to bring it over is the challenge. Is that better👍😁

Hey don't shoot me down!! Death pipe is what the the bunch over on the A2 owners club and other sites call it (Not me) I assumed you all called it that I'm new to the A2 FSI just looking for help and advice please don't jump on me with For goodness sake it's only leaking coolant pipe!! That's not much help to me or anyone else

Example for the Audi A6 2019 (MY2020). Part list as it did not fit on the screen grab.

I think a fundamental problem might be that some dealers will check to see if there is a Recall on a car. By this I mean a Recall that is proactively pushed to owners even if their vehicle is fine. I could be wrong, but I think that some dealers may not realise that there are a number of active Recall items that only become applicable if a given unit fails. In my case the affected part was the MHEV Belt Starter Generator.(BSG) Whilst it should not be necessary, it is worth keeping an eye on what recalls are in place on your car, so that if a relevant fault occurs you can take the evidence to Audi. An example is in my post above. This information is on the gov.uk website at https://www.check-vehicle-recalls.service.gov.uk/recall-type/vehicle/make

Wasted advice I'm afraid Steve. Swansea has not been back to the forum since posting his question.

Audi number is 032121065b If you want to google it. Its a pain of a job to do so only want to do it once hence the metal one if I can find one, Have a good weekend,

"Death pipe" is the sort of term I expect from America where everything is exaggerated to make a minor problem seem major. For goodness sake, it's only a leaking coolant pipe. It happens on all cars.

That should have said another challenge keyboard playing up sorry folks,

Sorry to hear that

Yes my brother has all the diagnostic kit betty him to bring it over is an challenge

Yes, no issues again today. I'll see how it goes, will let you know if there's any further developments. Rgds, Rich

Pd engine is a very reliable engine. Check for mayo round the oil filler. Might be worth getting the engine pressure tested. Obviously worse case scenario is a head gasket.

Sorry to hear this. If the warranty company are refusing to honour the unlimited labour rate then I'd argue this is warranty has been miss sold. So the dealer is partly responsible for this. I'd open a case with the motoring ombudsman but you'll be waiting 4 months for a case to be assigned.

If bought from a dealer they should fix this free of charge in the first 30 days after sale.

Yeah it’s very annoying this is my last issue tho hahaha hopefully 🤞 I have a pd130 awx code

Might be worth getting a diagnostic check to see if any fault codes flag up

Sorry to hear of your other issue. What engine has the car got?

Please keep us posted on any developments.
