Signum codes

HI All

I have one problem that will be sorted by soulman - CIM, however When the car is hot (90 degrees) and im in traffic the car shudders and revs to 1k and the EML light comes on. If i feel it coming on and rev the engine and it stops. The DTC reports missfire detected in cylinder 1 and 2. 1 is present with EML on and 2 is not present.

If i put my foot on the brake it does not stop the EML coming on but the revs drop to usual tick over. The other odd thing is i noticed it only really happened when the car trip says i have about 45miles left or when it goes into the fuel gauge between the last white bar and the first red.

i have also started using premium diesel and it seems smother.

I had a DTC for the fuel level sender and sometimes it takes sometime to pick up more fuel has gone in on both the gauge and the range. IS the car struggling for fuel as the gauge is off/crap in the tank? as if i stick some derv in it behaviours as it should do

I am also getting a range of other errors. They are below

Its a 06 3.0 V6 CDTI Signum with 89k on it.

Please help. I have only had it a month and have been so stressed i ended up in hospital with a suspect heartattack a week ago. I really like this car

[dave234]

Please ignore

P0425 - Exhaust Gas Temperature Sensor 1 Temperature not Plausible
(52) - Not present

I hadnt cleared the fault after i replaced the sensor

[domtorredo]

By dtc i see you got dpf fitted
Which could be answer to your problems
If car was drived mostly in town and never on high revs than defo its clogged up and needs regeneration
I guess you have opcom look through option and do dpf regeneration it will take some time and car will be running on high revs

[dave234]

Hey dom it did a regeneration on Saturday as that code haven't come.back since clearing them

[domtorredo]

Looking at faults again try cleaning egr valve

How car takes speed up to 40 -50mph doesn't take ages?

[domtorredo]

Ok than ignore question about mph

[dave234]

No its still rapid

[dave234]

I under stand that in September 06 there was a ecu update becausebof these egr faults

[domtorredo]

Will try to check that
With dtc p0235 check 3 pin connector at turbo could be poor conection

[domtorredo]

Yes there is field remedy 2071 end of oct 2006
