i brought my car in 02/08/2024 to be diagnosed for a low boost code. the tech did a visual inspection and noted boost coupler was loose and swollen. It's connected with hose clamps and could have been tightened. The coupler was replaced, two days later i get the same code. I contacted ***** on 02/13/2024 told him the issue and he said the turbos would need to be replaced. I asked for an estimate he said $5500. I asked for an itemized bill knowing the 2 turbos and all the complete upgrade parts would be under $2000 with the $300 core fee that can be returned after the job he made it seem like it they would have to be sent in before purchase. I requested multiple times since i want to see where the extra $3500 was going. I asked him if he could guarantee that would fix the code he said no. Then I was told to rule out anything else before the turbos he would have to do another diagnostic with smoke and pressure testing. That should have been done first before anything else with the initial diagnostics which I talked to him about when I got there. I've never been to a shop that does multiple diagnostics for the same issue and keeps throwing parts and charging or immediately wants to do the most expensive job first then back track to vac lines, charge pipe or other common failures that are know to throw boost codes on the e92 n54. My vehicle was not properly diagnosed a coupler was put on and i had the same issue. that could have been eliminated if the car was smoked and boost tested to isolate the issue. Now my tire rubs the inside of wheel well where he removed the trim when i parallel park, he did not put it back properly. i'm puzzled why he would not send me an itemized bill to explain the 5500 price when parts were under 2000 not to mention a 7% discount if i bought the turbos in cash and core fee of 300. once i questioned why he did not do the smoke test and boost test during the diagnostics and pricing he never responded. emails included shows conversation.
