Meet a rexton owner in PG during my vacationn to PG , the rexton was seriously underpower 0-100 its about 25 sec, can't uphill at all and the owner still driving it for around 1 year with this unsolved problem , HP pump serviced , service both 5 injector,new turbo, new modulator .. still the same ... the owner nearly give up with the car already...

After few round of testing noticed that the max rail pressure reading was 1380bar !!! it was exactly the Bosh commonrail value , after investigation comfirm that the diesel centre using Bosh Diagnosis tools to do the coding for his rex

Inorder to resolve his problem temporary , i had touched up his ECU map , uplift the rail pressure .. now at least the car doing 1550 bar rail pressure and the power restored .
Adviced him to send his car to fully reset the common rail value by using scan 100.

if any bro encountered under power issue , do check this issue before any parts replacement...

Wow, you like doctor healing all Rexton while on vacation. Maybe should paste a sticker "Dr Rex" so other Rexton owners can identify you easily.

Should recommend him to go for Eco Map instead, then he will fall back in love with his Rexton.

yeah, bro neonlee is healing the lame and blind. Next time going to PG, no need to take the bridge, he can just walk across.... :-)))

Great job mate, sure we have a new member for life now. Incredible, that you caught the 1380 bar rail pressure as the culprit. Guess the R&D department of MB in Untertürkheim would not have spotted it right away.

BTW, when is the next opportunity for me to upgrade to power map ???

Cheers,

Hahhaha.. "i believe i can fly ~" smile_tongue.gif
Luckily having a the scanner that can read the engine live data to find the culprit,base on the scanner can see the coding is done by 3rd party tools instead of Scan100.

Perhaps can update the power map for you by next gathering smile_big.gif
