Help! 2001 A4 1.8T quattro low engine oil pressure

[gnev34]

hello folks I am new to this site. I needed to get some advice on my car. I am the second owner on it and I have been good to my Audi. last year the turbo went out and I have had issues with the low pressure engine light coming on. Since then I took it to a well known shop. They started with the pick up tube for sludge and have gone through all the motions to a tune of almost 4k. The light continues to come on and they cant seem to figure it out. the conclusion was the instrument cluster.....well I have been to Audi dealership on this matter and they have ruled out the cluster and wiring. My concern is this.....Is it possible the engine block used to replaced the old one with is also bad? Is there a way I can identify the block to confirm it was switched out. any feedback would be greatly appreciated. At this point im feeling that 4k could have gone to a down payment on a new car.

when you say the shop went through all of the motions what else did they replace aside from the oil pickup tube?

That's only for low oil, you need to top it up. The usual problem is the microswitch in the hood latch has failed so the car doesn't realize you have topped up and will still display that. Low oil pressure has three long (ANNOYING) beeps accompanied wit "STOP, LOW OIL PRESSURE! I think you need to ask the garage for a rather large refund, take a baseball bat for persuasion and to teach them not to rip you off.
