Hi, John, My jaguar x-type 2.2d auto (54k miles) was difficult to start, turning but not firing up on an intermittent basis. Read about egr and when I tapped it, it would start. gradually got worse and I'd have to strike it several times and pump accelerator pedal like mad. eventually took it to garage and explained to them I thought it was egr and why. they ran diagnostic and apparently high fuel pressure was only fault found. they took off fuel filter and told me fuel pump had failed and released metal filings throughout fuel system. They said there were no other faults. I was told that the pump and injectors needed to be replaced and remainder of fuel system cleared of filings. I was shown a tray of fuel with what seemed to contain a very fine 'glitter' like substance. I agreed. the result was £1800 bill. I collected car and I started it from cold next day, but it only went on third or fourth attempt. Then, after a short drive of about 1-2 miles, a new warning light came on - 'gearbox failure' with coil lights flashing. After a few trips back to the same garage, they eventually discovered there WAS a fault with the egr valve. They fitted a new egr (without advising me of the cost). Of course, I paid the bill of a further £200 because I need the car and all seems okay so far. however, my concern is whether it was just the egr in the first place and they jumped to the conclusion it was the fuel line and I've paid way over the odds and paid for work that was not causing problem.

Garage are saying there must have been two faults at the same time, and erg fault was an 'incidental' not sure if they meant coincidental fault.

Do you think I should challenge initial works carried out and charges incurred? thank you
