SLK 230 PSE pump

Hi Guys.....

The PSE pump has been diagnosed as being faulty on my SLK230. My local MB dealer has quoted £450 to change it for a new one.

Can anyone give me some advice about replacing this unit myself? Where is the PSE pump located in a SLK? Is it a genuine MB part or can I buy it from another source (ie. Bosch, Lucas etc.)? Does it need setting up on a diagnostics machine or is it a simple part to replace? Where can I buy the part from (I am in the UK)?

Any advice appreciated.

Thanks
Martin

the right price is 322.50 euro if you go buy it yourself.

replacing it is very easy. it can be done with the simple tools provided with your car.

almost all of them are already coded which is not necessary to use the computer upon replacement.

i never been in UK and doesn't know where to buy it.

it is located at the back:

Many thanks Sleepwalker, that should save me a bit of cash! I just need to find the part now.

Sleepwalker (or anyone who can answer the question!)

I have managed to source a secondhand PSE pump, will this present any problems with coding when I fit it to my car?

Cheers

if it comes from the same model as your car, no need for coding.

Still need some help here guys.....

I have sourced a secondhand PSE pump for my SLK230. It is from exactly the same model and year as my car but the part numbers are different.

The PSE pump on my car is part number 170 800 0548
The part number on the secondhand unit is 170 800 1248

I want to make sure they are the same part before I part with my hard earned cash, can anyone reassure me???

Thanks (again)

Martin

better give me your VIN.

i cannot find 05 or 12 either.

Thanks for your help Sleepwalker.

VIN # is WDB1704472F146551

the right latest part number is: A170 800 08 48.
price is 322.50 euro

you can also use the older number 02, 03, 04, 06.

cheers.

Owners of later models SLK 2003/4 are saying that the pump now is fitted upside down so the water can drain out of the 3 holes in the cover, gets round the water coming down the cables.

Hi,
Where did you get a quote of 322.50 euro?
I've been quoted euro 535 + tax from a local MB dealer.
Thanks,

The price i was quoted recently from MBZ dealer was U.S. $510 (part only!) - waaaaay too much for what is essentially a design flaw (water coming thru via wires??)  Anyway, finding this as a replacement part is pretty impossible outside MBZ, however contact the salvage yards in the area and ask if they have an SLK...the way this part is designed it is pretty interchangeable through a number of the model years.  Also, the codes are already in, so it's pretty much a plug and play situation (not hard to remove, not hard to re-install)...hope this helps all others to avoid some of the frustration I went thru to fix my PSE

Thx Bazzle for the link and the instructions - actually, I read through it while trying to figure out what/where the hell the PSE was located - and so got the courage to try to do it myself!
 
Updating, I got the part installed - was able to put the unit back in upside down, which requires simply turning the unit on the horizontal axis (front becomes back) - this allows the wires to stretch so you can mount it upside down.  Did spray WD-40 in the connectors but not the conformal coating on the PCB  and...voila! It works

Uh - with one *minor* annoyance - everytime I go to turn on the car, as soon as the key hits position '2' the car alarm goes off for exactly one "honk" of the horn - right now, i'm too pleased with the $500 i saved to be overly concerned...but it would be nice to figure out how to fix it
 

my pump # 1708000488      used pump # A1708050019   will this work My car is a 2000SLK  the one I can get a pump from is a 2002SLK

bought a new pump from the dealer for $408.00 ( that was wholsale price) everything works great except the doors do not automatically lock when the car is put in gear or starts to move....anyone got any ideas?
