Hey, really (desperately) looking for some advice please!
I have a 17 plate Audi Q5 2.0 TDi Quattro. Car is driven up and down the motorway 3 days a week, gets a good run. Last Thursday, half way to work, EML comes on. Had it plugged in at work, given the code P200200 - Particulate Trap Bank 1 - Efficiency below threshold.
Since had it plugged it in at an Audi specialist (not dealer) and paid for the diagnostic report. The guy said I need: EGR cooler replacement, potentially 2 new sensors and a DPF clean due to mileage (83752).
Car is fully serviced but I have only had it since March. Tried my luck with the garage who sold it to me but they're saying as the fault wasn't present when I bought, I have no rights.
The Audi specialist quoted me between £1800 - £1900 - I simply do not have this kind of money spare. Wondering whether anyone has had the same issue and whether all of the above was required to fix it?
I have an RAC warranty which I now realise was a pretty pointless purchase, but trying not to dwell on that too much. I did call them and she said all of the above minus the DPF clean could potentially be covered but it all depends on the root cause. If it's soot build up/corrosion etc, it wouldn't be covered. If it's a faulty EGR cooler (which I highly doubt) then it would be covered.
I have people saying a DPF clean could potentially sort the problem, but I really don't know anything about this kind of stuff and I'm worried I'll just start paying out on bits here and there and the bill will mount up anyway!
The garage I bought it from are coming back to me today/tomorrow with an approx quote to fix based on my report and saying they will do what they can to get costs down but I'm not confident tbh. (They're 50 miles away annoyingly so can't even pop in to chase).
Any help would really be appreciated!
