Engine Management Upgrade
Does anyone know exactly what a Q068 engine management upgrade is please, and what it does. It was carried out as part fo a recent 36K service.

When I asked, the expalnation was, "it makes the engine more tolerant and expands the perimiters", that's answered that then!! Rolling Eyes

I've often found the engine very "!intolerant", it sometimes refuses to start at all when the mother in law is on-board! Wink

It doesn't say on the invoice, it just says "Carry out warranty upgrade Q068 to engine management system. This is on an 07 Puma 110.

The Q068 is going to haunt me forever I know it! All I can say is that it made my remap incompatable and has caused me a lot of frustration!

Q068 some info about version 2 can be seen here:

Page 2 of this thread mentions Q068 version 4:

I have just had mine done to V4 and the difference is very noticeable, more pulling power in higher gears and now accelerates like my TD5.
I may add that my unit has not been remapped other than by this LR patch.

Just had mine done to what i believe is V4 and yes it is much improved, feels more powerful, will pull higher gears at lower speeds than before and fuel consumption improved but as it was combined with new EGR valve, new Clutch and new gearbox selector shaft under warranty, can't be sure what has contributed what. MAD COW
