Limp mode - no faults

[M87NER]

hey peeps,

Does anyone have an idea why my car goes into limp mode every so often for like 10-15minutes? probs couple times a week, doesnt bring up a fault ect and if i switch the engine off and back on again it will still be in limp,

i.e. driving then i will try to boost but will be in limp mode....so i steady drive for 10-15minutes then try to boost again it will be back to normal, with in the 10-15mins i give it a little blip just to check if its still limp or not.


any ideas?

Thanks

Rich

faulty N75 valve possibly

 

[MIkey kc]

i have a standard one if you want it to try? you can have it for a tenner!

 

[M87NER]

I thought N75 but would that no reset if i turned the car off for 5mins? it has a standard one on atm its only about a year old this one, was thinking of trying to get a H or J type see if they make any difference.....ect

 

[M87NER]

Vould also try your standard one aswell see if it does stop it , cheers, have meet up ....

there's another thread 'power problem' running which also discusses this same issue.

i fitted mine with a brand new h valve, went for a blat last night and it cut off boost again but mine only does it for a couple of mins.

Cheers olethalb i'll have a look at that...

i dont think the valve would reset itself if you turned the engine off, i think its the valves inside getting stuck or sumthin like that. when i worked at seat we did get a couple of cars in with your fault and it was just an n75 valve, intermittant boost faults like the maf was knakered, but no fault codes.

i will pm you my mob number- wont be able to have it this weekend tho sorry because its in my tool box at work which is closed.

I have not long fitted an n75j i think it works a treat!

Cool, cheers Mikey Kc.

am still getting this with a new N75... any other things i can look at?

 

[Myki da Pyki]

Could be a coilpack on its way out mate cos they wont bring up a code until there almost dead

Testing.....

Testicals...

 

[MIkey kc]

strange could you explain the fault abit more? do you have your hybrid on now? has it been remapped?

 

[M87NER]

ooo am back online...... yeh its hybrid now and been mapped up, fitted a j valve lets see what happenss now,

Just to check, I've been getting this also. I do have a N75J at home that came with the car, the guy before me says he took it off because it caused alot of surging. Has the N75J sorted your problem out mate?

 

[M87NER]

nope still happened with the j valve, i ended up getting new spark plugs and a new maf but then it still happened and then completly went ito limp mode and wouldnt come out... so started to strip the car down to check the hoses and found a pipe had popped of the bottom of the tip,

 

[Wilkeh]

I think im running a similar setup to yours? I may have to do the same and strip it down a little. Vagcom just pulls up some problem with the MAF and running lean however the MAF is only a week old.
