Sudden limp mode under acceleration, but no code.
Question Sudden limp mode under acceleration, but no code.

Hey 2nd Gen owners...

I'm having a continuing issue that's quite literally "driving me crazy."

My Clubby is a '08 Clubman S with 107000 on the clock. It is unaltered but the dealer I got it from turns out was a shyster and abused the heck out of this car and left nearly every possible maintenance concern unaddressed for a long time and then polished it up and sold it to me for a really low relative price. I should have known, but everyone has to pay the stupid tax sometime in their lives...

I fell in lust with the car and now I'm paying the price to make it all right. So far I've spent the four months I've owned it fixing every major component in the engine bay and it had SEEMED that my independent Mini certified mech had it all fixed but even after thousands of $$ of repairs, I've found myself in the shop again twice this week with a persistent Check engine light. Something is throwing the engine into limp mode but not showing any codes when hooked up to the computer.

After having the water pump, thermostat and the pipe between them as well as a heater core hose replaced Tuesday, it was running as good as I'd ever heard or felt it... Then that evening under moderate acceleration while the turbo was in boost, the CEL popped on and the turbo cut out.

The light never reset until I took it to an autozone and had them put their computer on it. It showed NO codes and when I restarted it, the CEL CLEARED and it was back to "new normal" again. The car ran great all afternoon/evening and the the next morning did it again! I took it back to my mech and HE found vacuum errors using his more sophisticated computer. He replaced a small, cracked vacuum hose and unbent a crimped line on a sensor which the shady dealer had left hanging loose instead of re mounting it. My mech had me drive while he monitored his computer live while it was linked to vacuum data and it checked out great. So I left happy and ready to motor... All good until last night when it did it AGAIN under the same conditions, except I was pushing it harder (going around an annoying Impala driver who thought his LT was a match for a Mini S) plus the engine was warmer this time.

So, now I'm back at my Mech waiting to hear the latest cost for this issue.

All of this is to ask, has anyone ever had a problem like this and what did it turn out to be? How did you finally (hopefully) fix it?!?!

Thanks!

Auto Zone won't be able to read the codes it's throwing. Need something more specific to BMW / MINI, like a BavTech cable and software. Until you read those codes.... You'll pull your hair out.

Maybe a problem with the turbocharger recirc valve, possibly a torn rubber diaphragm?

it could be carbon build up in the intake. You can have it walnut blasted to clean it up. With that mileage it may be time.

This link shows what it looks like.

Still sitting on the shop.

After another smoke test, a check of the diverter solenoid and finding nothing, it is still throwing a vacuum leak code, so they are going through everything...

With 107,000 on the clock I am betting Carbon build up.

Carbon build up even if its not the cause of your problem now should be on your to do maintenance list.

At that mileage I'd bet you a dozen donuts you have carbon buildup. DI is great, until you need to shoot walnuts. If you post your location someone may be able to point you in the right direction to good MINI mechanic.

I had the carbon removed at about 108,000 on my '08. I wasn't throwing codes but it did make a huge difference in response.

Is the turbo itself OK?

Well, with so many votes for carbon buildup and the legendary way these '08's suffer this malady, I'm inclined to believe it. I mentioned it to the service manager and he said possibly and that it DOES help performance to walnut blast it, but he's concerned that there's nothing wrong with the turbo before assuming it needs to be blasted, so they are looking at that first. it is the intermittent way it is happening that's not yet convinced him of carbon, but he says it's on the list.

Thanks for the responses all!
