I own a Volkswagen Golf Estate Mk6 1.6 TDI. I bought it a year ago as a family estate and I like the car a lot. Recently the EGR valve failed, luckily under main dealer warranty. At the same time as this was replaced, I had the emissions fix done. I have heard that after the fix, the EGR valve is more likely to fail again. The main dealer has suggested, therefore, that I run the car at least monthly for 20 miles at 3500rpm and I have read your advice to rev to 4500 through the gears (which sounds a lot easier to do). I do a short local work commute (about 7 - 15 miles each way) and general family, dog stuff and occasional holiday journey (roughly 10,000 miles a year). We have no local motorway and, although the recommended 20 mile blast is possible, I find it ludicrous that I have to do this. Do I simply own a car with a poor engine and/or, could you again offer your sensible advice on running the car to try and avoid future EGR failure?
