Hi,

My 2000slk 230 just got trouble codes p1235 and p450. I think p1235
is the k40 relay, but I'm not sure about p450. Can Anyone provide
any information on this?

Thanks,
J

 

if the car is shaking from one side to the other and the revs will not "go" above 2500 or 3000 than you need to check out your k40. i had the same trouble with my slk 200 2.0 non kompressor. do not do anything else check your k40 first!!!!!!!
if you dont fix that first, youll be seing all kinds of "codes"!!!! do not do anything else but remove your k40 with a new one!it costs 125 euro includindtaxes etc. in europe that is.. [8D]

 

any news on the issue?
