Another limp mode problem

[Rsv75]

Hi, I have just joined the group hoping you experts can help me please.
2011 rcz 200 68000 miles.

car had being going into limp mode with engine warning light on.

After reading the fault codes I Had the garage fit a full new cam chain kit and vvt solenoid valve. Two coil packs were also changed. Previous to this the in tank fuel pump was also changed due to non starting.
the problem is however still persisting. Them codes have gone but I am getting
p1057 and p1147. I think p1072 is the vvt motor and p1147 is another coil pack. Can someone confirm this please?
if I need to change the vvt motor would I be best with a used genuine one or a cheaper new copy part for around £120?
new genuine ones will be very pricey and a bit of a gamble for me
The car right now starts and drives perfect at low revs (with light on) but anything over half throttle and it will stutter, go into limp mode and misfire juddering as it drives. Fans on full blast for 10 mins after switching off. Start back up and ok again until more than half throttle and same again.

Any help or advice would be much appreciated. Spent over £1000 now ….

Check the fuel pressure & trims you might consider changing the Cam or Crank sensor or both together
Limp mode & stuttering with poor acceleration could be timing or fuel delivery?

 

[Rsv75]

Thanks for the reply. How do i Do that? With my reader on live data?
can you confirm my current codes relate to vvt motor and coil packs?

Thanks Scott

I hope you haven't been led on a merry dance and have possibly been fleeced when it could be the high pressure fuel pump.....get thee to a thp specialist if you can.

Live data will show the trims on acceleration as for the VVT & coil packs these may need to be investigated as if 1 or 2 are failing then replace all 4 same with plugs you didn't say if fault showed up as Bank1 for ignition timing coherence but this can occur with cam/crank sensor problems usually on the intake cam
My 200 still has original coil packs which are given a long life spec & plugs (which can overheat destroying a coil pack) were changed when I bought it on 37.085 & are still firing the VVT valves are usually fooked up by filthy oil with other engine components which rely on clean oil & good pressure

It was a good job the cam chain kit was done tbh. The crank cog was loose and the guy couldn’t believe it hadn’t fallen off apparently.
he is a specialist in this engine but with mini coopers. He’s a mechanic for rally mini rally cross championship I believe.

Thanks for the info. The original codes showed mismatch between cams and crank timing I believe.hence why timing chain kit was fitted. I’ve ordered coil packs now. And a guaranteed good used vvt motor to try.
prob next step will be cam/crank sensors then hpfp??

 

[Rsv75]

Hi all. A quick update.
I have now fitted new coil packs and a guaranteed good working vvt motor. That thing is a pig to get in and out. Anyway. Started the car no problem and now it ticks over fine but doesn’t want to Rev up at all so it is un drivable. Still engine management light on and now reading different codes p1030 and p0013. Has anyone got any ideas please? Basically I have made things worse!!
one thought I have is how by winding the vvt motor into the cylinder head and engaging it with the cam it may have advanced or retarded the cam into the wrong position. Does it need to be set in a certain way or will it sort itself out electronically?
Really hoping someone can advise.
thank you

P0013 Generic in all variants -B Camshaft position -Actuator open Bank 1 poss exhaust cam problem it can mean the valve is faulty?

 

[Rsv75]

Hi, a little update. 2new vvt valves fitted but still p1030 code and limp mode all the time. Have got the rocker cover off to check that the vvt motor is working. with the motor out of the engine but connected to the plug and cycling the ignition it spins backwards and forwards no problem. With vvt motor connected , fitted to the engine and cycling the ignition it does move the gear/shaft but Does sound a little rough. photos are of the gear itself. It does look worn.
mum a bit lost now. Any ideas please???

 

[Chillipip]

I remember reading somewhere (possibly even on the forum) that when the lift gear is worn it’s a cylinder head replacement as it’s all in one or not available as a separate part.

I found the below video showing the gear being tested using a scan tool. The engine shown is the non turbo 1.6vvt but same concept

 

[Rsv75]

I have also read that too. The car starts ok but just ticks over and won’t even really Rev when in neutral never mind trying to drive it. I’m stuck now so please fire away with ideas

High there
I am a new member
I have just had a similar adventure, car would start when cold and very soon would show an engine light and would not rev and was lumpy (Limp Mode) also the cooling fan would come one and stay on for many minutes after the car was turned off.
Found that when the engine got warm it would run ok but with the engine light on
Changed the timing chain etc as it was showing a mis match between crank and cam sensors
seemed ok but within a day or so away from home, the fault re occurred again with the cooling fan coming on.
After clearing the codes found that it was now showing showing low fuel line pressure.
Removed the high pressure fuel pump and measured the distance of the diaphragm to the body of the pumps pressure expansion valve.
This measure 29mm where it should be 22mm meaning that there was not enough oil in the pump for it to work
changed the pump for one from Neo Bros £635.00 and it all seems ok for now fingers crossed

 

[Rsv75]

Pleased you got yours sorted.
Mine is only showing one code now. p1030 VVL system fault. Need to get to the bottom of this as the car can’t be driven right now.

 

[Rsv75]

Can anyone tell me how to do an ecu reset please?

 

[Rsv75]

Pulled the spark plugs to replace and found two of them to be like this with the tips broken off. Surely can’t be helping.

 

[Pascal]

hello Rsv75

are these really broken off or melted away ?
If these are broken off then the piston should bump into them or am I seeing this wrong

 

[Rsv75]

I think they have eroded away but difficult to tell.

 

[Pedro]

Tip is broken off by looks of it barring continuous overheating caused cooling & pre ignition (Timing related) other thing to consider these engines are interference where the piston would make contact on mechanical failure

Thanks pedro. Makes perfect sense. Timing chain done now so that shouldn’t be an issue. Will see what happens with new plugs in. Would damaged plugs be enough for limp mode??
