Interesting Dtcs And Intermittent No Boost.

[Olley]

Hi all.

Been smoking around in a 1998 mk1 galaxy for about 7 months while my other car is being played with.

 

but since i've owned the old bus it's never boosted, at all. until the other day when i took it in for an air con service. it now boosts but only when started from cold. (the fella who did the air con said the maf was unplugged)

 

i've also had the DTCs read, as my Bluepoint microscan won't connect.

 

the codes are as follows

 

01237 fuel cut off mechanical malfunction

 

65535 ECU defective, intermittent

 

00741 Brake pedal check not plausible (new pedal sensor fitted months ago)

 

00575 Map sensor deviation

 

has anyone had any thing like this before and could point me in the right direction? i do all work myself. (aside from the air con) and could use a few pointers as to where to start.

Diagnostics wise its a case of using vcds (a cheap vag com cable and the free version is adequate for checking for codes and clearing them) assuming your using the diesel engine version (which the boost references would suggest you are)

 

The brake pedal sensor message is probably old from what you have said anyway.

 

65535 ECU defective, intermittent - this has popped up before and doesn't appear to be anything major its more like unspecified error than anything precise - see

Generally its probably best to get the codes cleared and then drive it and rescan for codes, though the same combination has come up elsewhere > http://www.fordgalaxy.org.uk/ford/index.php/topic/23800-19tdi-diesel-fuel-feed-problem-r-reg/page-4?hl=00575&do=findComment&comment=170939

 

I think I'd be looking at the map sensor referenced to in that post and your error code listing if the code still appears.
