2005 e53 3.0 d - sluggish start - starter or IVM?

Google44 · #1 09-10-2014, 10:20 AM

Hi

I've got a problem where the starter motor does not spin the engine as it should. It always starts but you always think it is not going to as engine is span very slowly. I've read elsewhere that it is usualy starter motor or IVM (battery is defo OK)

Is there a way to be sure before I comit myself for second hand starter? I've messure the Amp on crank taken by starter and it is around 400 A. That sounds a lot. The starter is made by DENSO pn 7788680.

thanks

What is IVM?

My starter motor started making a weird sound back in August. Luckily, I was in Ukraine, 40€ later it was removed, fully rebuild and reinstalled. If I was in Greece, I would probably have paid about 400€.

Thanks for replies. It is defo slower then friend X5 next to it. It start after a few spins but them few spins should be in a few secs. I can count the revs of starter.

I will try the second hand starter. Apparently, same fault is on 7 series with same part number 7788680. 400A defo taken when spec claims around 180. So it could be only the starter. I can see previous owner put a large 110Ah battery to address the issue.

Hey fella, did swapping the starter solve your issue with sluggish start? and was the sluggish start worse in the cold? I did some digging around and the draw should not be over 180a when engaging starter, excuse my ignorance you said you measured 400amps, how?

If you battery checks out and charging system too then that leaves the starter I guess...

3.0d battery/slow starting problem?? Read on pls

I had a clamp meter around battery feed which showed over 400 A on crank. Replaced starter motor and all OK now.

Thanks

Thanks for reply will get this test done at a car electrician, don't have an amp clamp or a meter that can read that high alas, just curious when they do this test do they wrap clamp around battery cable and just startup car? finding more and more of these results

Did you replace the starter motor yourself? Was it difficult, any tips on how to go about it?
What brand Starter motor did you use to replace ?
