Hello to all, I recently hit a large racoon @ 65 MPH which caused some serious mechanical damage to my 2011 COOPER S R56 N18. The MINI dealership gave me an estimate for $6,800 to fix everything which I could not afford. They gave me a list of the parts it needed along with all of the part numbers. I towed it home and installed the following new parts: Radiator, AC Condenser, Electric Fan Assembly, Aux water pump, water pipe, Head Gasket, Cylinder Head Bolts, Intake and Exhaust Camshaft Sprocket Bolts. The engine will turn over but not start. A local shop ran a diagnostic and got the following faults from the DME: 2C58 , 37DE , 2937 , 299A. I noticed from the report, that the software they used at the shop was Autologic.....which I have heard does not work all the time for clearing codes and values....but I don't really know. I think the main issue is the FAILED COMPRESSION TEST: 1 - PSI 54, 2 - PSI 48, 3 - PSI 54, 4 - PSI 55. I'm not really sure where to go from here, any advice would be much appreciated.

 

I can't imagine how hitting a large raccoon could cause the head gasket to need changing.

As for low compression, did they indicate wet or dry test? And was it done before or after the head gasket change?

But without a lot of mini repair experience, I would expect your problem to be workmanship --- timing or head gasket install. Browse thru these repair procedures --- https://www.newtis.info/tisv2/a/en/ and find the timing test using a feeler gauge.

With all the front end damage, there's bound to be a broken / missing sensor signal or two that will keep the ECU from going thru the engine start process, i.e., coolant level, ambient air temp.
