Exhaust Cold Start Unit
Hi All,
I have searched but unable to find the answer.
I have replaced my turbo that went pop and after an exiting time bleeding the cooling system all appears well.
The turbo however lost its turbine fins bit on the exhaust side of the turbo unit it just snapped off and away it went down the exhaust.
The exhaust system appears to be working fine but when idling or on start up its most musical as the fin bit rattles about and runs up and down the pipe on (de)acceleration.
I have the North Japan cold start box on the exhaust and need to know before I start undoing all its bit and bobs what is in the box.
Can I open it up, remove its gubbins and my turbo bit and put it together again, remove the box and clamp the two pipe ends together, fit a spacer or just turn the radio up!
Cheers
Boots

Re: Exhaust Cold Start Unit
oh dear.
are the turbo bits from the old one or the new one.
the winter pack diverter valve can just be removed,as its a bit over the top for uk,and they tend to seize through lack of use,if you remove it you will need a new section of exhaust(longer) and blank off the air supply pipe with a bolt and clip round.
better just to unbolt the unit at the engine side,fish out your blades and reatatch and leave alone/dont use untill the exhaust needs replaced.

You can't polish a turd - but you can roll it in glitter.

Yup, that's all the cold start gubbins.

Re: Exhaust Cold Start Unit
Think I'll leave well alone for now but if the front of the exhaust needs replacing I'm tempted to remove it all.

Re: Exhaust Cold Start Unit
When I had my exhaust replaced with a stainless steel one the guy doing the work said that he had made exhausts for lots of BMWs with the exhaust inhibitor and that he always removed them following advice from BMW. UK being a lot warmer than Germany.
So I had mine removed and the mechanic blanked off the vacuum tube which operated it, been running oh for 4 years.
