Mini cooper 2885
Was going to do case study but had no documentation so I figured at least get this info out there since it was difficult for me to find anything. (No i don't use Google, I get annoyed easily by forums due to so many arm chair specialist)
Car gets towed in, crank no start. I go out, obviously timing jump no compression. Was going to document with pictures but relative compression was barely anything all flatline, had 0 compression on all cylinders. Welp this won't be interesting so I didn't take pics or anything, but turns out the intake cam and crankshaft was in time perfectly, exhaust however was about 90 degrees retarded every valve bent. Thought weird no slack in chain. Removing vacuum pump and it was seized. One of the veins slipped out and locked it up. Get the head back all new timing components and goes together great. Runs awesome, but code 2885 comes up. Based on the description it's obvious it's boost related. Identifix, all data, Mitchell had nothing. Checked vacuum lines one was melted through and blocked which would cause the wastegate to stay open all times. Repaired hey wastegate moved, awesome code 2885 returned, pulled blow off valve, its in pieces, I snapped it back together, and it worked but comes apart easily. Replaced code returned, this time noticed wastegate would move the second engine started. So pulled intake again and found the vacuum solenoid always bleeding vacuum. Now I did find the purge valve and vacuum valve is same connector and wiring, but there is obviously more slack for the vacuum valve unless not in its bracket you can't mess it up. Only reason I checked is an old Honda got me once. But the info may be important. Now new vacuum valve all would work correctly with handheld pump and scan tool. All finally was well. Basically every one of these things, along with boost sensor which is also the baro sensor. Back pressure, intake leaks, faulty turbo. Can cause this code. It's not a hard code once you figure it out, maybe this info can help someone be a little faster at the diagnosis than I was.
Thanks for that update, there was another mini cooper that was having the same problem, hope he can read this and get to the bottom of his headache-thanks once again.
Sean, you work at the Milford location? I'm from the east side and know the location well. Thanks for the posting.
Okay, that's even closer tome. Quick question. Cam you guys do a chemical carbon clean on a 18 Honda CVR 1.5 turbo. If so, do you fog the intake? My wife bought it new and the dealer tells her she don't need it done and I keep telling her it needs to be done. Has 30,000 miles on it. DFI Turbo. If you can, I'll call and get it in to get it done.
We have a basic 3 step process. Clean the throttle body, fuel additive, and run a chemical drop in the intake. Personally if it's a plastic intake I don't like to. If it's bad enough ie. Misfiring i recommend taking the intake off and clean the valves
