EGR, Ad Blue, DPF delete

[Lacey86]

Hi all, I just got my car back from the garage as engine light was on and got fault codes P2002 & P20E8. Technician notes say, after further test, they think the EGR cooler is likely blocked and Ad Blue pump has failed as no signs its engaging when initiated. As I drove away the DPF 650miles light came on, which wasn't on before. Not sure why.

Anyway, they're putting a quote together but the lad on reception reckons at least £2500, which I don't have right now. 

I'm looking into other options and notice a lot of people online seem to overwhelmingly steer towards a delete and gut the DPF which they all seem to say saves a ton of money, makes the car run better, is way more fuel efficient with no issues at MOT (if certain parts left in) and no warnings on the dash. After reading I see this technically makes the car not road legal.

My concern is I really don't want to devalue the car. It's the best car I ever owned, has pretty much all the added packs including tech pack, Virtual Cockpit, Bose Sound System, upgraded suspension amongst others. The mileage is only 75k and according to AutoTrader is worth about 11k.

If I delete the EGR, DPF and AdBlue am I risking never being able to sell the car again? 

Is there any other option than paying £2.5k or deleting? I've seen someone online say you can try an exhaust system flush and cleaning service. Has anyone tried this and it fixed the fault codes? 

I'm not daft but I'm also definitely not mechanically minded so please be kind ha. 

It's worth noting that I have never modified the car in anyway, no re mapping or anything. I just use it to get from A - B and want it to be in the best condition possible.

Hi the exhaust system flush will not cure your problem, deleting the adblue may well solve that problem, the only way to cure P2002 is to replace the cooler and valve unfortunately I did it three times on my A6, its an inherent design fault which is like a disease without any real cure, if you listen to some of the waffle about delete this delete that its all wonderful which is why I sold the car a few months later.

Thanks Steve, did you pay to get yours fixed before you sold it? I've just the quote in from the garage, £3620!! Is that normal for P2002 and P20E8 fault codes??

Hi I did get it fixed but I never got the chance to sell it as it rolled off of my local garage forecourt into the brick wall across the road, electro mechanical handbrake failure caused by a voltage drop on the battery which is another favourite trick of the cars from 2014-2017, no the price you have been quoted is not normal as I never paid more than £1600 for the cooler unit to be replaced bearing in mind you could only get the parts from Audi at around £700, now you can get aftermarket parts around £450, my advice would be to get the adblue mapped out and then the cooler fixed as cheaply as possible then get rid of it ASAP, beautifully made car body wise and a joy to drive BUT parts are ruinous price wise and as mine was used as a cab frequent, got a Passat estate now not as glamorous but is as nice to drive and any parts are about a third of the price.
