2011 SEAT ALTEA XL SE CR TDI ESTATE - Seat Altea XL fuel pump needs replacing at 27K 13 Jun 2015 (Forum)
I took the car in for a service as I had done just shy of 10K miles, its now on appx 27K. I was quite shocked to find out that the diesel fuel pump needs to be replaced at a cost of appx £1200, with the part costing £722.

Small economical hatchback 26 Mar 2014 (Forum)
The main reason for selling it is because she does 50 miles daily. It's reached 100k now and is terrible on fuel. We want to reduce fuel costs but not necessarily a diesel...
