Reply With QuoteI have had success with the rubber feet on mine by sanding them back with some fine emery paper to flatten out the indents.

SupporterHaving mucked around with this EAS for a number of weeks I am convinced that the problem with these valve blocks is the seals in the bottom of the 4 air bag line solenoid shafts rather than the o rings so much. I had heard of someone drilling them out and replacing with a 4mm thick rubber plug. Has anyone done this? as I note that the current plugs are well indented and I fear if any leaks in the block are happening it is from this area.
PS. the base of the lower shaft with the spring on it.

Subscriberyep, 2000 grade wet 'n' dry which has been soaked in soapy water for an hour and left wet. Persistent gentle abrasion cleans them up quite well!
Master
SupporterThanks Paul I will give that a go.
Would be worth adding that procedure plus checking the position of the top rubber top on the same piece, to the O ring rebuild steps and doing a short test with each solenoid with a 12v feed to check operation before putting it back in the car ( I know prolonged direct feeds may burn out solenoids so testing this way is for short burst only to check initial operation).

SubscriberHmmm ... I seem to recall that the solenoids are only 5 volt...need to check this out before pressing the button!
Master
SupporterHappy to be corrected in the voltage as I am only retelling what I was advised by a far more knowledgeable person than I in these matters. No surprise if they burn out then but he definetly told me to use a 12v feed.
Master
SupporterHoges the sensors are at 5Volts but the solenoids are 12v as detailed in this service bulletin P38 EAS Service Bulletins

Are these the 'indented' ones you mean ? - They rest on top of the internal volcano-shape and seal... hopefully...Originally Posted by PaulP38a
That O ring in the pic can easily be a problem, if its not 101% correctly seated on re-assembley.
Don't ask how I know...

SupporterYep that's the one

A similar thing happened to me, but I think the small black piece had fallen out and I had put it back the wrong way.
