Which model is this? Convertible? Because my sportback comes out of the pillar.

I'm assuming the light came back on since your reported on July 1st that it was ok?

I think we've crossed wires here. I was asking Steve about his EGR cooler and pressure sensor he mentioned in his post I quoted.

What model, and mileage was it?

Hi Steve, How's the car running since you had the EGR cooler changed? Did you change the valve too? Was it the cooler or the G450 sensor you needed to adapt? UDS Protocol (G450) procedure Key ON, Engine OFF [Basic Settings] Select Adaptation of diff. pressure sensor particulate filter [Go!] to activate the Basic Setting. After the result of Finished Correctly appears click [Stop] Select Resetting of learned values of difference pressure sensor [Go!] to activate the Basic Setting. After the result of Finished Correctly appears click [Stop] [Done, Go Back]

As Steve and Stevey have already mentioned, P2002 is caused by a blocked EGR cooler, though it's worth doing a voltage check on the G450 sensors too because that's the pressure feedback. I was strongly advised to not delete the EGR cooler, so to avoid failure of components/engine from overheating 12-18 months later. You could be lucky and get away with replacing an £80 sensor vs. £1k for an EGR valve and cooler replacement, but you're already experiencing it getting hot quickly, so chances are it's blocked.

I've since used this: Autoglym VRC500US Vinyl & Rubber Care, 500ml https://amzn.eu/d/2LTVxQJ Very easy to use; all seals done in around 10 minutes. And I'm really pleased with the outcome.

So what's the learning here? If something is not clear, get clarification in writing before you sign the deal.

I just don't get it. All this effort for what is essentially an extra £20/month on a car that's being rented at a cost of what? £300-500/month? I wish this was all I had to concern myself with in life. It's all relativel I guess 🙂

Thanks for the summary. I've never had a car on a lease, but I'd personally expect details of the service to be in writing so there's no ambiguity. The A5 I bought had been serviced on the 2 year/18600 miles and so had my wife's Golf. They were both 4 years old from a lease. I realise none of this is helpful, and really cannot relate, so all the best with this - I hope you achieve the desired outcome.

Someone help me out here please. Is the issue potentially having to spend an extra £400 over a 3 year period? Or any fallout from the car not being serviced according to the recommended schedule?

Quick update: Car is booked in to have the EGR Valve and Cooler replaced. I'll get some photos of the old parts, and do a quick summary of my experience and learning when it's done.

Done! Perfect

It's behind the glovebox. If you cannot see this from the manual in the A5 forum, I'd advise you take it to a garage.

Is it possible to do so?

I've disabled it using VCDS but it doesn't stop it from becoming active when the ignition is cycled. The only way I know of is to manually disable in the MMI at the start of every journey.

I've had it happen once in the five or so months I've owned my A5 when the postie crossed the road and I'd moved over to give him more space, but I was only doing around 10 MPH and not using ACC. It's a shame the original post was not followed up.

Where do you live? Dealers sell the recirculation flap motors for £219 Inc VAT in Cambridge area. I've not had the cambelt done on mine yet. It's coming up to the 5 year point in September, so I'll have it have it changed then. My old A4 B8 diesel was around £450 with water pump.

I heard dealers vary their prices, but I never thought it would be so much!

Great you have this sorted. Did you buy the part, or the specialist?

Indeed, it does turn black quickly. I've never let an oil change go past 10k, so you become familiar with how it looks/smalls at that point. Maybe I just need to move on with the times 😄

I have an unused bottle of that. I recall buying it for one last effort, but then I lost interest 😕

No, I don't have photos. The manual extract posted on May 16th shows where it is.

Yeah, I've seen the one from states, but as you say it's over-priced even without shipping and potential customs. My only desire for this is to see the oil condition, but I suppose that can wait until the end of year when I do the interim oil change at around 9k miles.

I realise the level can be checked in the MMI but has anyone fitted a physical dipstick to the B9? If so, which part did you use?
