Hard to give a value without knowing which car, what year, other spec, general overall condition.
I think @
gerrywac has a BXE, so hopefully he can shed some light on reliability.
I still have my 07 Mk5 1.9tdi BXE engined Golf now a few weeks over 13 years old, 9 and a half years since I bought it as a one owner car with Fsh.
It's now on 94k, just over half mine and I have had very little bother with it and running sweetly as ever.
No breakdowns, ran out of fuel once, one accident, one boost pipe failure and several limp mode episodes but nothing that was down to the engine.
When I bought the car in December 2010 I joined several VW and VAG forums including this one to learn how to look after it and I came across a few posts about BXE engine failures that disturbed me quite a bit as I was concerned that I might have bought a dud. I spent quite a lot of time over several months researching the issue through numerous car and mechanic forums, technical groups and several VW mechanics. When I'd finished I found perhaps a dozen and a half posts of BXEs throwing a rod over a number of years but with little or no consistency over the age, mileage, oil use, service regime, revs/speed at failure etc and nothing to support suspicions over a batch of dodgy rods,, cranks, big end bearings, cap bolts which had been suggested and having regard to the large number of engines fitted to the 4 marques over several years nothing to suggest the numbers were in any way unusual or high.
As to the two specific points mentioned I haven't had any issue with either, I had seen mention of EGR sooting and checked at services but mine is in no way excessive and I've had no need to touch it. I can't say I've noticed a post over several years now so haven't had any reason to think it's anything other than rare and random and I stopped worrying several years ago
