APPROX EVERY 10 MILES MY ROOMSTER GOES INTO SAFE MODE, IF I THEN LEAVE IT FOR ABOUT1/2 HOUR, IT COMES OUT SAFEMODE ON ITS OWN AND DRIVES FAULTLESS UNTIL YOU DO A 10 MILE RUN.BEEN TO ONE DIAGNOSTIC FIRM AND THEY SAY TURBO NEEDS RESETTING,? BUT THEY ALSO SAID THAT DOING THAT COULD MAKE IT WORSE RESULTING IN NEEDING A NEW TURBO.!!I CAN'T UNDERSTAND THAT.CAN ANYBODY OUT THERE HELP PLEASE. THANKS, GARY

Is your Roomster having a cbzb engine? If so had the 24w6 tpi campaign been performed? 

 

If yes there should be a sticker under the trunk cover. If not this may solve your problem. 

Sounds like an overheating problem, which resets when it cools down.

 

Assuming excess heat not being caused by low oil, or low coolant, or blocked water pump, or ancient oil that is not circulating then :

 

might be faulty sensor

possibly a sticky turbo (carbon build up)

possibly turbo oil feed pipes part blocked so turbo struggling.

 

If it does need new turbo, make sure oil feed is also changed, otherwise new turbo will also fail if cause is oil starvation.

 

Might be worth a tank full of premium fuel with cleaning additives, to see if it can clean some deposits, might not work, but relatively cheap compared to repair

 

Would be easier to identify if someone can plug in and get fault codes before resetting happens

 

Can you advise what mileage, engine type etc

 

Also Is it more time related (after a certain time from start up, rather than normally done about10 miles)

WILL TICKOVER ALL DAY. DONT OVERHEAT BUT DID NOTICE OIL WAS LOWON BOTTOM MARK ON DIPSTICK. COULD THAT HAVE DONE IT,. NOW TOPPED UP BUT NOT RETESTED YET

MY MISTAKE ITA A 1200 NOT1600

@yellski Look, I know it's your screen name, but will you stop shouting?

 

BTW the first things I'd do with this sort of problem are:-

1. Check fluid levels.
2. Find a garage that can explain what they're talking about in terms you can understand!
