Limp mode but no engine light?

[ChrisCurzon]

Think my cars gone into limp mode its only boosting to max of 7psi then dropping to 5 or less after, did a scan on vag com only thing that came up was 1 Fault Found:

18010 - Power Supply Terminal 30: Voltage too Low

P1602 - 35-10 - - - Intermittent


cleared it off and dident come back on but still not boosting properly.

what we things happend?

thats only comes on when you disconnect the battery i believe -

strange how no other codes have come up -

can you do a log of 118 which measures req v act

 

[ChrisCurzon]

havent disconnected the battery :S

only disconnected ecu when was looking at the part number if that does it.

will try do it tomorow see what its doing. seems to be running better than it does normally now though lol.

 

[ibizacupra]

power off ecu = that code

i know it gets said a million times but have you checked all vacum hoses?

 

[ChrisCurzon]

that will explain the code then cheers bill.

theres new ones on there as though that was a problem abit ago so dont think that the problem will double check every thing and do some logs.

 

[mr_D]

what dv u got mate? Have you tried others on there. My car only ever went into limp mode before i done the bypass. Has only happened once since but thats because my turbosmart was open full

 

[ChrisCurzon]

found the problem the vaxc pipe on dump valve had a hole in it again, how do i stop it from doign that it keeps rubbing on the a/c pipe behind and putting a hole in the vac pipe.

Buy your self some superflexi pipe and relocate your dv.

Do the cold side relocation

Maybe extend the vac line so it doesn't rub

Just 3 options you can choose from. There are others as well mate

 

[ChrisCurzon]

will have a look at it done it twice now put a bigger long vac pipe on this time but made no diffrence it seems.

will see if can get a cable tie on there and pull it away abit.

 

[mr_D]

sure it will be easy enough. Have a look on the turbosmart dv thread and you will see pic's of my relocation. £30 is all it cost.

 

[freddie]

can the dv be moved to cold side when running forge fmic (pipework wise)?

cheers for that had a look not hard to do 2 flex pipes move it away maybe good idea to do.
