Well the plot thickens, had the egr replaced and dpf reading okay
New issue, wouldn't start today, they came out and used starter pack to start car, went for a drive to charge the battery and all lights on my dash came on, power steering failed and headlights would not work! Car also will not look using remote and is now parked outside my house unable to start ??
Did you pay any of the purchase price of the car on a credit card? If you did, you could try for a refund via your credit card company if this all turns really sour and the vehicle turns out that it isn't fit for purpose. And on that note, if you have one, I absolutely advise anyone buying a car from a garage, whether franchised or independent, to pay either the deposit or the balance on a credit card as doing so gives you as the consumer a great deal more protection under the Consumer Credit Act 1974.
I'm wondering now, did the car come with any service history? Do you know whether the vehicle has had any MOT advisories?

How many former keepers has the car had? (you'll find that on the log book if you have it)
Checking these things can give a little bit of an idea of how well (or not) the vehicle has been looked after.
